It gives banks, fintechs, and enterprises the infrastructure to run financial operations and build products onchain, provisioning wallets, securing keys, governing transactions, and servicing tokenized assets across blockchains, the way a traditional core banking system underpins accounts, payments, and ledgers in conventional finance. The platform addresses a structural gap. The core systems financial institutions run today were not built for assets that settle in seconds, on public networks, with cryptographic ownership. Rather than replacing an organization's existing core banking system, hardware security modules, or compliance stack, DFNS provides the layer that lets those systems operate onchain. It is delivered as composable modules through one REST API and SDKs, so an organization can adopt a single capability or the full platform, and it connects to more than 100 blockchains and third party services through a single integration surface. Over 400 institutional and fintech clients run on DFNS, including Standard Chartered, First Abu Dhabi Bank, IBM, Stripe, Circle, Kraken, and Apex Group. Roughly 1% of all global stablecoin payment volume settles through the platform. DFNS is used across digital asset custody, banking, embedded wallets, stablecoin payments, trading operations, tokenization, and treasury and asset management. The platform is organized into modules, including: 1. Wallet-as-a-Service — create, index, and manage wallets across 100+ blockchains and third party services, as one account layer for custody, payments, trading, treasury, and tokenization. 2. Transaction Management — format, approve, decode, simulate, sign, broadcast, and track transactions at scale, built for high volume flows and complex approval logic. 3. Treasury Management and Tokenization Engine — manage onchain treasury across entities, currencies, and networks, and issue and service tokenized assets across their full lifecycle. 4. Policy Engine and Governance Engine — enforce limits, allowlists, quorums, roles, and ABI aware approvals before every signature, and cryptographically verify every intent, policy, and signature against a state the customer controls, deployed within their own perimeter. 5. Key Management — run keys across MPC, HSM, TEE, or BYOK models, with production grade protocols built for resilience, scale, and no single point of failure. A defining characteristic is that authentication and transaction signing are handled as separate functions, and policies are evaluated before any signature is produced, giving organizations programmable control over who can move which assets, under what conditions. Keys are operated so that a complete private key is never assembled in one place. DFNS can be deployed as managed SaaS, hybrid, or fully on premises. The deployment model changes while the modules and controls stay the same, allowing key material and infrastructure to be placed according to regulatory and operational requirements. It integrates with existing systems including core banking platforms, custody and compliance tooling, and payment rails, and organizations typically adopt it to add digital asset capabilities to existing products, to meet requirements under frameworks such as MiCAR and DORA, or to consolidate wallet, transaction, governance, and settlement operations onto one platform. ## Dfns Pros & Cons **What users like:** - Users appreciate the **great customer support** from Dfns, enhancing their experience and confidence in the service.

Scaling with Confidence Using DFNS **Rating:** 5.0/5.0 stars **Reviewed by:** Jordan P. | CEO, Small-Business (50 or fewer emp.) **Reviewed Date:** July 19, 2026 **What do you like best about Dfns?** DFNS continues to deliver meaningful enhancements to its platform, including new capabilities such as cross-chain swaps. Previously, our team relied on a third-party solution outside of the DFNS dashboard, but these new secure integrations now allow us to manage the entire swap process within a single environment. This gives us greater operational control while simplifying reconciliation and improving overall efficiency. One of the standout aspects of working with DFNS has been their support. They maintain an active support channel with specialists covering technical questions, implementation, and general product guidance. Given that our team operates across multiple time zones, their responsiveness has been especially valuable and has helped keep projects moving without unnecessary delays. From a technical perspective, our CTO noted that the integration was straightforward and well documented, allowing us to get up and running quickly with minimal friction. I personally find the dashboard easy to navigate and saves our team time when adding new wallet structures and policies. Finally, their pricing is extremely competitive, particularly considering the quality of the platform and support they provide. As we continue to scale, we're looking forward to moving into the next performance tier together as our transaction volumes grow throughout Q3. **What do you dislike about Dfns?** We always want to understand the risks associated with adopting new technology. In our view, every company—including DFNS—benefits from sharing real-world case studies where market participants experienced losses, operational failures, or security incidents. Those examples are often the most valuable learning opportunities for customers. I’m a strong believer in taking guidance from experienced industry leaders and learning from situations that have already occurred in the market. Transparent case-study guidance helps companies make better decisions around security, operational controls, treasury management, and incident response. While we have had a very positive experience with DFNS, we believe the industry as a whole would benefit from more structured educational content focused not only on successful implementations, but also on lessons learned from real incidents and how those risks could have been mitigated. That kind of transparency ultimately strengthens trust and helps all participants improve their security posture. **What problems is Dfns solving and how is that benefiting you?** As DFNS continues to build the infrastructure layer for moving programmable money around the globe at the speed of the internet, it allows companies like ours to focus on what we do best—building exceptional user experiences, growing our business, and serving our customers. DFNS has solved one of the most complex and sensitive pieces of the payments puzzle: secure, automated digital asset infrastructure. By abstracting away much of the operational and security complexity, they've enabled us to accelerate product development with confidence while maintaining the controls expected of a modern financial platform. Rather than spending our engineering resources building and maintaining wallet security infrastructure, we can invest our time in innovation, marketing, and delivering value to our customers. That's exactly the type of partnership we're looking for as we continue to scale. **Official Response from Christopher Grilhault des Fontaines:** > Thank you for the review, and in particular for the second half. You are right that this industry publishes wins and buries failures. We can point to our own record, which is zero breaches and zero security incidents since August 2020, but a clean record is not an education. The instructive material sits in the incidents that happened elsewhere: blind signing, compromised operator workstations, approval flows with one real human in them, key ceremonies with a single point of failure. Each one has a control that would have caught it. We try to write them in the security section of our blog. Structured teardowns of public incidents, with the specific policy and governance configuration that would have prevented each. Let us know if there is anything specific you'd like to dive into. ### 2. Highly Customizable, Friendly UX with Responsive Support and Flat-Fee Pricing **Rating:** 5.0/5.0 stars **Reviewed by:** Ganesh M. | Investment Principal, Small-Business (50 or fewer emp.) **Reviewed Date:** July 28, 2026 **What do you like best about Dfns?** Highly customizable, super friendly UX, great asset coverage, with focus on local cloud deployments. Also integrated into Canton- which is a network we are bullish on. We are also able to implement multi party policy control on several of the workflows that are common to a VC- which helps us make the best use of the product. The pricing, being flat fee is also very helpful for a small team that can handle higher assets under management. The team is super responsive at both the UAE level and at the global level and have addressed war related downtimes very quickly. **What do you dislike about Dfns?** They have some reliance on single party cloud providers in a region- even though that got fixed quickly. **What problems is Dfns solving and how is that benefiting you?** Custody and validator ops on canton. transaction monitoring and admin for Further Infrastructure labs Wallet cycling, simplified MPC control of digital assets. **Official Response from Christopher Grilhault des Fontaines:** > Thank you for the detailed feedback, and good to hear both the UAE and global teams showed up when it mattered. On cloud concentration: our SaaS platform runs three clusters, in the US, the EU and the UAE, all inside AWS. That gives you regional isolation and data residency. It does not remove single provider dependency, and you are right to name it. With that said, our track record on the SaaS platform is perfect: zero breaches and zero security incidents since August 2020. For clients where that risk matters, we support hybrid and on-premise configurations. You run signers on your own cloud accounts or your own hardware, and DFNS never holds the full picture. Both options are available to you today. ### 3. Smooth Integration, Intuitive UI, and Outstanding DFNS Support **Rating:** 5.0/5.0 stars **Reviewed by:** Matt O. | CMO, Small-Business (50 or fewer emp.) **Reviewed Date:** July 21, 2026 **What do you like best about Dfns?** The platform’s functionality and UI are easy to navigate and provide exactly what we need. The integration process was smooth, and the overall performance has been satisfying. When we did run into issues, the DFNS support and dev teams were extremely helpful and efficient, resolving everything much faster than we expected. Overall, we’re very satisfied with the product, which is why we decided to choose DFNS as our wallet infrastructure provider. **What do you dislike about Dfns?** The only minor issue we’ve noticed is that passkeys don’t work seamlessly in Chrome on macOS and often cause problems. **What problems is Dfns solving and how is that benefiting you?** DFNS provides us with the wallet infrastructure for the issuance and distribution of our MiCA-regulated euro stablecoins. If we had to build this ourselves, it would take months and an unreasonable amount of funds and energy. **Official Response from Christopher Grilhault des Fontaines:** > Thank you for the review. Good to know the integration went smoothly, and that the team kept up when it did not. On passkeys in Chrome on macOS, you are not imagining it. That combination is the messiest one in the WebAuthn ecosystem, because Chrome, iCloud Keychain and Touch ID all want to own the credential. Two things help right now. Have users register a second passkey on another device so nobody gets locked out when a prompt misbehaves. And it is worth checking your rpId and origin settings, since misconfiguration there looks a lot like this. Also tell support which failure you are hitting. The prompt never appearing, dropping to the phone QR flow, and the credential not being offered are three different problems, and we would rather chase the right one. One more thing. If you are not using policy-gated mint and burn controls on the stablecoin side yet, that is worth 20 minutes with your account contact. ### 4. Outstanding Support, Competitive Pricing, and a Crisp Developer Experience **Rating:** 5.0/5.0 stars **Reviewed by:** Niko L. | Co-Founder, COO, Small-Business (50 or fewer emp.) **Reviewed Date:** July 16, 2026 **What do you like best about Dfns?** Rapid, helpful, and technically deep customer support for the products that we pay for, as well as a fully fleshed-out and understandable product development timeline. The product performs well, the price point is extremely competitive, the developer experience is crisp and easy to grasp, and it works as advertised. **What do you dislike about Dfns?** I dislike that the product is billed in EUR rather than USD. **What problems is Dfns solving and how is that benefiting you?** We needed a platform to be able to spin up self-custodial smart wallets en-masse for users, in an API-forward way, with full ability to control every lever of the process and ensure that our customers' self-custody was maintained across the implementation. We assessed several providers, and struggled to find ones that had the features and the capabilities that DFNS provides. **Official Response from Christopher Grilhault des Fontaines:** > Thank you, Niko! Your feedback means a lot. We'll fix the billing issue for you, we are able to bill in USD as well. Feel free to ping our finance team on the support chat. ### 5. Extremely responsive team, easy to integrate, and a dashboard that keeps improving **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Financial Services | Small-Business (50 or fewer emp.) **Reviewed Date:** July 22, 2026 **What do you like best about Dfns?** The responsiveness. When we reach out on Slack we get answers fast, and the turnaround on issues is excellent. That matters more than anything else when you're running custody in production. The platform is easy to use even if you're not technical. I'm on the product side, not engineering, and I can find my way around it without help. The documentation is outstanding. Our engineers integrated DFNS with very little back and forth, and the docs carried most of the weight. **What do you dislike about Dfns?** Not much worth flagging. The one thing I'd have called out six to nine months ago was the dashboard UI, and they've improved it a lot since. It's much easier now for non-technical users, so credit to the team for that. **What problems is Dfns solving and how is that benefiting you?** DFNS gives us the wallet and custody infrastructure behind our digital asset features. We needed something our engineers could integrate quickly and that we could operate with clear controls over who can do what. On the enterprise plan we feel we get real value for the money, from the platform and from the team behind it. **Official Response from Christopher Grilhault des Fontaines:** > Thank you for your feedback, and for calling out the dashboard specifically. A lot of work went into it over the last year, so it is good to know it landed! Please continue to tell us what you want next in the dashboard. You are exactly who we build it for. ### 6. Rock-Solid Wallet Infrastructure with Secure Passkeys and Responsive Support **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Small-Business (50 or fewer emp.) **Reviewed Date:** July 21, 2026 **What do you like best about Dfns?** What stands out most is how solid the core wallet infrastructure is for a production app. The API is well documented, and the signing and key management gave us confidence we weren't compromising security for speed of integration. Support for multiple blockchain networks meant we didn't need separate providers or custom logic per chain, which saved significant engineering time. The use of passkeys for authentication is a standout feature, it gives users a much more secure sign-in experience than traditional passwords or seed phrases. Pricing was very good for the value delivered, especially compared to building and maintaining this infrastructure in-house. Support during integration was responsive; when we hit edge cases specific to our mobile flow, we got direct engineering-level answers rather than generic tier-1 responses. **What do you dislike about Dfns?** Overall everything worked well. There wasn't much to dislike. On the few occasions where something didn't behave as we expected, the team was quick to jump in and get it resolved, often turning around fixes or adjustments faster than we anticipated. That responsiveness made the rare rough edges a non-issue. **What problems is Dfns solving and how is that benefiting you?** Before working with Dfns, building and securing our own wallet infrastructure for the app would have meant a significant investment in cryptography, key management, and ongoing security maintenance, all outside our core focus as a social and crypto platform. Dfns solved that by giving us production-ready wallet infrastructure with strong key management and multi-chain support out of the box. Now our team can focus on building the actual product experience instead of maintaining low-level wallet security. This has resulted in faster time to market, less engineering overhead spent on infrastructure, and more confidence in the security of our users' assets since that responsibility sits with a specialized provider rather than being something we maintain ourselves. **Official Response from Christopher Grilhault des Fontaines:** > Thank you for the review! We especially appreciate your point about getting engineering-level answers rather than generic support. Passkeys also remove one of the biggest risks of seed phrases: they cannot be phished, copied, or entered in the wrong place. And yes, the same address works across EVM networks, so adding chains often does not require creating new wallets. ### 7. Effortless Integration with Amazing Support **Rating:** 5.0/5.0 stars **Reviewed by:** Andrew A. | Founding Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** July 16, 2026 **What do you like best about Dfns?** I use Dfns for wallet infrastructure for a non-custodial retail application. The ability to integrate with multiple chains very quickly is a significant benefit for me. I really enjoyed the ability to use pass keys on mobile devices, which users find convenient. I liked the customer support the most; the team was always available on Slack or Telegram, making it easy to get in contact and get help, which is especially valuable when you're not a big customer. I never ran into any issues, everything integrated fine, and the support was wonderful in helping me understand the documentation. I like the API as it was more full-featured at the time we switched from Privy. The initial setup of Dfns was super easy, and we got live in a couple of hours, connecting, testing, and then building it out over the next week. **What do you dislike about Dfns?** Nothing **What problems is Dfns solving and how is that benefiting you?** Dfns allows me to integrate with multiple chains quickly and use passkeys on mobile devices, making things easier for users. **Official Response from Christopher Grilhault des Fontaines:** > Thank you, Andrew! ### 8. A Core Component with Stellar Security and Flexibility **Rating:** 5.0/5.0 stars **Reviewed by:** Gaspard L. | Co-founder, Small-Business (50 or fewer emp.) **Reviewed Date:** July 17, 2026 **What do you like best about Dfns?** I love that Dfns is a core part of our tech stack at Suby because it allows us to handle multi-chain and multi-asset transactions with a lot of flexibility in how money moves. Their strong security reputation gives us trust in how they manage stablecoins, so we don't have to deal with the complexity, risk, or licensing. I have a close relationship with one of the founders, and the team listens, moves fast, and is accommodating to young companies like ours. The initial setup was super easy. **What do you dislike about Dfns?** Honestly, nothing to report for now **What problems is Dfns solving and how is that benefiting you?** Dfns lets us avoid the complexity, risk, and licensing of holding stablecoins, with a strong security reputation we trust. It offers multi-chain, multi-asset capabilities and flexible money movement. **Official Response from Christopher Grilhault des Fontaines:** > Thank you, Gaspard! ### 9. Intuitive APIs, but Errors and Stability Can Improve **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User | Small-Business (50 or fewer emp.) **Reviewed Date:** July 29, 2026 **What do you like best about Dfns?** We use Dfns to provide wallets to our clients and perform On/Off Ramp operations. I like the way the APIs were made; they are very simple to understand. **What do you dislike about Dfns?** The mapping of error scenarios is not very good, Dfns returns very generic errors in various situations, and we always have to get in touch to understand what actually happened with the transaction. We have been facing stability issues on the testnet networks, especially when making transactions on the Sepolia Ethereum network, where transactions get stuck in the Broadcasted status. Additionally, I think there could be greater flexibility in the policy rules; currently, when I register a policy that can be approved by a service account, we are required to provide the user IDs as well. **What problems is Dfns solving and how is that benefiting you?** Dfns simplifies communication with the blockchain, which would be costly to build internally. However, the errors are generic and the error scenarios are poorly mapped, we need to contact support. Stability in testnet networks and the flexibility of policy rules also need improvements. **Official Response from Christopher Grilhault des Fontaines:** > Thank you for the detail. This is more useful to us than a high score. On errors, you are right. Parsable errors are specced and in the queue, i.e., named reasons on failed transactions and transfers, such as INSUFFICIENT_FUNDS_FOR_FEE, GAS_LIMIT_TOO_LOW, AMOUNT_TOO_SMALL, and DROPPED_BY_BLOCKCHAIN. That takes support out of the loop. Until it lands, every error response carries an "id." Quote it to support and you get the exact trace with no back and forth. On Sepolia, for transactions stuck in Broadcasted, the Speed Up and Cancel endpoints let you replace the transaction now rather than wait. DROPPED_BY_BLOCKCHAIN will make that state explicit instead of leaving it ambiguous. On policy rules, requiring user IDs alongside a service account approver is a real limitation. It is with the product team as a named request. Almost there! Reach out to product@dfns.co for more information about timelines. ### 10. Quick Integration and Responsive Support with Dfns **Rating:** 5.0/5.0 stars **Reviewed by:** Dominique R. | Small-Business (50 or fewer emp.) **Reviewed Date:** July 27, 2026 **What do you like best about Dfns?** I like the ability to easily integrate cryptocurrencies of our choice thanks to Dfns. Their support is also appreciated because it is responsive and helps us fix issues. I am also satisfied with the security of their platform. **What do you dislike about Dfns?** I think the interface part could be improved, especially regarding the wallets section. Today, when wallets are integrated, they are all listed on the same page, or even on multiple pages. I think it would be interesting to have sub-menus by cryptocurrency. **What problems is Dfns solving and how is that benefiting you?** We can quickly integrate new wallets and cryptocurrencies with Dfns, which is fully secure with responsive support. **Official Response from Christopher Grilhault des Fontaines:** > Thank you for the review, Dominique! We're proud supporters of you and your team. The issue you mentioned was actually fixed two weeks ago. You can now filter wallets by asset directly from the Wallets page. The option is inside the filter dropdown, so it may have been easy to miss. ### 11. Simple Integration, Useful Dashboard, and Solid Security **Rating:** 4.0/5.0 stars **Reviewed by:** Robert S. | Summer Analyst - FICC & Equities, Small-Business (50 or fewer emp.) **Reviewed Date:** July 22, 2026 **What do you like best about Dfns?** The integration was simple, and the dashboard experience is genuinely useful. The pricing is good, and security is solid. When issues came up, they were resolved quickly. **What do you dislike about Dfns?** There isn’t anything specific I dislike; it’s more that some specific features are missing, such as delegated multi-user wallets. **What problems is Dfns solving and how is that benefiting you?** DFNS secures wallets for us and our clients, providing wallet security infrastructure across EVMs, Solana, Tron, and more. **Official Response from Christopher Grilhault des Fontaines:** > Thank you, Robert! Your feedback means a lot. We’ll be investing more in delegated wallets this quarter and through the end of the year. Please feel free to ping us on Slack with any similar requests or use cases. ### 12. Highly Customizable, Surprisingly Efficient **Rating:** 4.5/5.0 stars **Reviewed by:** Franz S. | Mid-Market (51-1000 emp.) **Reviewed Date:** May 11, 2026 **What do you like best about Dfns?** I find Dfns to be customizable, which is great as it offers a licensing wrapper in certain regions. The integration time is shorter, and I have the option to choose between HSM and MPC models, which is beneficial for expanding to certain jurisdictions and needs. I also like that the product can be tailored and the on- and offramp network is strong, allowing us to go beyond the wallet infrastructure and use other providers. The initial setup has been going well so far. **What do you dislike about Dfns?** More preset configurations **What problems is Dfns solving and how is that benefiting you?** I like that Dfns is customizable with a licensing wrapper for certain regions. It shortens integration time and offers flexible security models, enabling expansion. The strong on- & off-ramp network also enhances provider options beyond wallet infrastructure. **Official Response from Christopher Grilhault des Fontaines:** > Thank you, Franz! Appreciate the feedback. Have you seen our latest "Role Templates": https://www.dfns.co/article/introducing-role-templates. Hopefully that's one step closer to more preset configurations. We also intend to roll out Policy Templates and Automation Templates soon. ### 13. Fast, Responsive Support and Rapid Feature Updates **Rating:** 5.0/5.0 stars **Reviewed by:** Chanwoo P. | Chief of Staff, Small-Business (50 or fewer emp.) **Reviewed Date:** July 27, 2026 **What do you like best about Dfns?** They move really fast when it comes to support, and they’re quick to introduce new features as well. **What do you dislike about Dfns?** Nothing here to report particularly. Fairly satisfied. **What problems is Dfns solving and how is that benefiting you?** Highly configurable wallet infrastructure that requires minimal integration effort. **Official Response from Christopher Grilhault des Fontaines:** > Thank you, Chanwoo! We are very proud to support you and your team. ### 14. Simplicity and Exceptional Support for Blockchain **Rating:** 5.0/5.0 stars **Reviewed by:** Moises Z. | Small-Business (50 or fewer emp.) **Reviewed Date:** July 22, 2026 **What do you like best about Dfns?** I like the simplicity of Dfns and their technical support. When there is a problem, we can resolve it quickly. Additionally, new products and everything integrate very quickly and easily. The initial setup is very easy. **What do you dislike about Dfns?** I think we should have monthly meetings about the product's development. **What problems is Dfns solving and how is that benefiting you?** Dfns simplifies Blockchain infrastructure and allows us to solve problems quickly. The ease of integrating new products and the efficient technical support are noteworthy. **Official Response from Christopher Grilhault des Fontaines:** > Thank you, Moises! Our CPO will reach out to schedule a monthly call and keep the conversation going. ### 15. Great Support and Regular New Features **Rating:** 4.0/5.0 stars **Reviewed by:** Uladzislau R. | CTO, Small-Business (50 or fewer emp.) **Reviewed Date:** July 27, 2026 **What do you like best about Dfns?** great support, new features are added regularly **What do you dislike about Dfns?** everything is good, can't think about anything that I dislike **What problems is Dfns solving and how is that benefiting you?** we are using dfns for our internal and external crypto treasury management **Official Response from Christopher Grilhault des Fontaines:** > Thank you, Uladzislau! We appreciate the positive feedback. At your disposal should you need anything. ### 16. Clear Documentation and Rich, Flexible Functionality **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Financial Services | Small-Business (50 or fewer emp.) **Reviewed Date:** July 16, 2026 **What do you like best about Dfns?** The documentation is clear, and the functionality is rich, offering a lot of flexibility. **What do you dislike about Dfns?** If I had to pick one issue, DFNS’s dashboard is pretty unpleasant to use. I sometimes get hit with rate limits, and the address search doesn’t always work. **What problems is Dfns solving and how is that benefiting you?** We really like the gas sponsorship features and the ability to bring your own Canton validator. We also appreciate the nonce management and how it supports the overall functionality. **Official Response from Christopher Grilhault des Fontaines:** > Thank you for the honest feedback. We’ve done a lot of work on the dashboard recently and will keep improving it. The address search issue is a bug, and we’ll look into it. Rate limits can be increased with a simple message to our team on the support chat, so feel free to ping us anytime. Glad to hear fee sponsorship and the bring-your-own Canton validator are working well for you. ### 17. Intuitive Integration and Support, But Wallet Management & MPC signature messages Needs Improvement **Rating:** 3.5/5.0 stars **Reviewed by:** Lucas G. | CEO, Small-Business (50 or fewer emp.) **Reviewed Date:** October 20, 2025 **What do you like best about Dfns?** Dfns has been straightforward to integrate into our platform. To be honest, you do need developers to handle the integration, but the thorough documentation makes the process much easier. The product is also very intuitive for end users, and we benefit from an excellent team behind the product who are attentive to our feedback. **What do you dislike about Dfns?** There are a couple of aspects we would like to highlight. Firstly, the MPC messages that need to be signed are not user-friendly, which makes it difficult for signers to clearly understand what they are approving. Secondly, the front end for managing wallets and policies is quite complex, as there is no way to organize the information efficiently. Even a basic feature like organizing policies and wallets by "tags" would significantly enhance the user experience. **What problems is Dfns solving and how is that benefiting you?** At Ethernodes, we provide our customers with custody services for their digital assets, along with yield-generating products -based on custody-. This requires the product to be extremely robust—essentially a bunker—when it comes to interactions between customers and DeFi. Dfns supports us by establishing an environment with clear rules that make it easier to determine who can interact, when, and how. This helps secure both the funds and DeFi deployments needed to generate yield. **Official Response from Christopher Grilhault des Fontaines:** > Thank you, Lucas! This is really helpful feedback that we’ll take back to the team. Improving the user and admin experience on the dashboard is a top priority for us right now. Dfns has always been an API-first product, but we’re now focused on making it safer and easier to manage for non-technical users, something the market is clearly asking for. ### 18. Smooth DFNS Integration with Clear Docs, AI Help, and Responsive Support **Rating:** 3.5/5.0 stars **Reviewed by:** Verified User in Financial Services | Mid-Market (51-1000 emp.) **Reviewed Date:** July 28, 2026 **What do you like best about Dfns?** Integration with DFNS has been smooth. The API is straightforward to integrate, and the documentation is comprehensive. There's also an AI assistant on the docs page that helps our engineers get answers directly without back-and-forth. Support from the DFNS side has been responsive and prompt. **What do you dislike about Dfns?** No major pain points so far. The integration experience, documentation, and support have all met our expectations. **What problems is Dfns solving and how is that benefiting you?** DFNS provides the key management and signing infrastructure that lets us scale our custody operations securely without building and maintaining that layer in-house. **Official Response from Christopher Grilhault des Fontaines:** > Thank you for taking the time! Good to hear the docs and the Ask AI assistant are doing their job. We rebuilt both this year, so that feedback is landing where we hoped. ### 19. Good UI, fast start, and attractive price **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Financial Services | Small-Business (50 or fewer emp.) **Reviewed Date:** July 27, 2026 **What do you like best about Dfns?** - good UI - fast start (no complex governance setup) - attractive price vs. competitors **What do you dislike about Dfns?** I can't think of anything specific that I don't like. **What problems is Dfns solving and how is that benefiting you?** - secure storage and access to private keys of admin wallets - custody of crypto assets **Official Response from Christopher Grilhault des Fontaines:** > Thank you for your feedback! At your service should you think of any missing feature. ### 20. Effortless Setup and Robust Wallet Infrastructure with Constant Updates **Rating:** 4.5/5.0 stars **Reviewed by:** Ibahima S. **Reviewed Date:** October 27, 2025 **What do you like best about Dfns?** I appreciate Dfns for its low entry cost and robust infrastructure, which made it an excellent alternative for our needs compared to other expensive options. The setup process was straightforward and easy, which was a great start for us. I'm impressed by the robust wallet infrastructure that Dfns provides, especially with its prebuilt integrations with third-party vendors, which saves us a lot of time and effort as we don't need to integrate them individually. The core functionality of the wallets, particularly sending and receiving, is extremely beneficial for our operations. Additionally, the fact that Dfns frequently ships new features shows their commitment to constant improvement, which is crucial for us. Lastly, I value the team's support and the ongoing updates, which give me confidence in their service. **What do you dislike about Dfns?** I don't like the limited support for USDT, which restricts our operations in certain markets we cover. Additionally, more blockchain support on USDT tokens, including integration with Solana, would be highly beneficial for us. I also feel that incorporating low-cost on-ramp and off-ramp features and integrating a card program would enhance the platform's offerings. **What problems is Dfns solving and how is that benefiting you?** Dfns provides robust wallet infrastructure and prebuilt third-party integrations, solving major integration issues and facilitating seamless operations. ### 21. Incredibly Helpful Team Support from Dfns **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Financial Services | Small-Business (50 or fewer emp.) **Reviewed Date:** July 16, 2026 **What do you like best about Dfns?** Their team was incredibly helpful even having their own CEO to support across the entire process. **What do you dislike about Dfns?** Not much to highlight about things we dislike about Dfns **What problems is Dfns solving and how is that benefiting you?** Getting Lightning Network integrated to their stack was a major win. **Official Response from Christopher Grilhault des Fontaines:** > Thank you so much! ### 22. Exceptional Support Made DFNS API Integration a Breeze **Rating:** 4.5/5.0 stars **Reviewed by:** David A. | Chief Technology Officer, Small-Business (50 or fewer emp.) **Reviewed Date:** October 23, 2025 **What do you like best about Dfns?** The support team was incredibly responsive and knowledgeable, which allowed me to implement the DFNS API in a very short amount of time. **What do you dislike about Dfns?** The complexity of the API results in a steep learning curve, but it is still manageable. **What problems is Dfns solving and how is that benefiting you?** Users require an easy method to interact with blockchains, especially when they do not have existing wallets. It is important that they can quickly get started with a highly secure wallet that is directly linked to their account. **Official Response from Christopher Grilhault des Fontaines:** > Thank you, David! This is very valuable. Our Head of Product will reach out to you to learn more about the complexities that make the onboarding and configuration of the product sometimes difficult. We want to simplify the developer experience as much as possible. ### 23. Outstanding Tech, Perfect Pricing, and Top-Notch Security **Rating:** 5.0/5.0 stars **Reviewed by:** Berhan K. | CEO, Small-Business (50 or fewer emp.) **Reviewed Date:** October 21, 2025 **What do you like best about Dfns?** There are 5: 1) They have nailed the pricing structure for payments companies. 2) Great natively built-in security around the MPC wallets with an additional on-premise option. 3) Extremely well working customer success processes. 4) Great coverage on all L1 blockchains. 5) Overall, great tech that just works. Best I have seen. **What do you dislike about Dfns?** There isn't anything about Dfns that we don't like as Keyrails. We integrated it once and it just works. We only contact them to get information about the new features and how they work. **What problems is Dfns solving and how is that benefiting you?** Keyrails' entire stablecoin payments stack is built on top of Dfns' tech. All stablecoin custody and money movement goes through Dfns' API. ### 24. Valuable MPC and Workflow Features, But Usability and Security Could Improve **Rating:** 3.5/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Small-Business (50 or fewer emp.) **Reviewed Date:** October 23, 2025 **What do you like best about Dfns?** Having an MPC on Canton is definitely valuable. Additionally, the ability to set up approval workflows and matrices is particularly useful in this environment. **What do you dislike about Dfns?** Other networks offer solutions that are significantly more user-friendly. While I appreciate that MPC eliminates the need for hardware wallets, as someone who prefers cold wallets, I find these options less secure. For example, my computer could serve as an attack vector, and even the physical security of a yubikey is not guaranteed. **What problems is Dfns solving and how is that benefiting you?** Decentralised wallet management with the ability to setup policies. In other case, we would rely solely on EOAs with unique user credentials. **Official Response from Christopher Grilhault des Fontaines:** > Thank you for your feedback! Indeed, Dfns is an API-first company and we take pride in offering the best programming interfaces of the industry. When it comes to the dashboard, we still have work to do. Fortunately, we have hired a great team of frontend engineers this year and you should be seeing significant improvements in the coming months. The hard part is to build the security, the infrastructure, the APIs, and that's done. We look forward to getting your updated feedback next quarter as we keep improving the user interfaces. ### 25.

The team is highly accessible and eager to collaborate, making it a pleasure to work with them. Their responsiveness and continuous improvements, especially in evolving security standards, are commendable. Additionally, Dfns excels in providing a key management system that is quick, scalable, and simple to implement, even for lesser-known or pre-launch blockchains. **What do you dislike about Dfns?** N/A Great trajectory and growth. **What problems is Dfns solving and how is that benefiting you?** Dfns frees us from transaction building, offering a scalable, easy-to-implement transaction signing mechanisms even for less-known blockchains, simplifying our project delivery. **Official Response from Christopher Grilhault des Fontaines:** > Thank you, Anoosh! ### 26. Very happy **Rating:** 5.0/5.0 stars **Reviewed by:** Pablo P. | Chief Executive Officer, Small-Business (50 or fewer emp.) **Reviewed Date:** October 23, 2025 **What do you like best about Dfns?** Cybersecurity reputation and willingness to integrate our own blockchain technology to their wallets. **What do you dislike about Dfns?** EU base. I am in Hawaii so live communication was delayed. **What problems is Dfns solving and how is that benefiting you?** WaaS and cybersecurity are the main ones. Custody is also important. **Official Response from Christopher Grilhault des Fontaines:** > Thank you, Pablo! ### 27. Works exactly as advertised **Rating:** 5.0/5.0 stars **Reviewed by:** Olivier S. | CTO and Co-Founder, Small-Business (50 or fewer emp.) **Reviewed Date:** May 09, 2024 **What do you like best about Dfns?** The solution is easy to use even in the most complex situations. Great documentation makes it quick and easy to get started. The customer service is very responsive and knowledgeable. Newer standards, techs, protocols, DTLs etc. are proactively incorporated into the solution so DFNS wallets always work regardless of your needs. They keep on adding new features and improving their tooling's User Interfaces, making the solution easier and easier to use. **What do you dislike about Dfns?** The wallets are so secured and permissions so fine-grained that it's sometimes difficult to reason about the best way to secure assets, but it will certainly satisfy the most complex enterprise requirements. However, their new UIs greatly help making the most basic use cases easy to reason about. **What problems is Dfns solving and how is that benefiting you?** I want to keep my customer's assets secured and easily control who can access the wallets and sign transactions. I don't have to worry about managing secrets keys **Official Response from Christopher Grilhault des Fontaines:** > Thank you, Olivier! We're lucky to have you as our clients. ### 28. Easy-to-Use SDKs and Portals Make Development Simple **Rating:** 5.0/5.0 stars **Reviewed by:** Mamadou D. | CEO, Small-Business (50 or fewer emp.) **Reviewed Date:** October 16, 2025 **What do you like best about Dfns?** Easy to understand and straightforward SDKs and portals. **What do you dislike about Dfns?** N/A but could extend the flexibility for any ERC-20 token support with no prior approval. **What problems is Dfns solving and how is that benefiting you?** Managing and auditing wallet infrastructure can be challenging, but DFNS is tackling this issue by providing dedicated wallet addresses that include segregation features and wallet tags. This setup simplifies the process of reconciling transactions with our off-chain internal ledger. **Official Response from Christopher Grilhault des Fontaines:** > Thank you, Mamadou! We've taken note of your request for extended ERC-20 token support. ### 29. A great wallet infrastructure for a fintech provider **Rating:** 5.0/5.0 stars **Reviewed by:** Jasper F. | CEO, Small-Business (50 or fewer emp.) **Reviewed Date:** June 12, 2025 **What do you like best about Dfns?** Robust, highly flexible and configurable API. We've quite a few applications of it within our system for businesses as well as for users. The team is incredibly responsive and supportive. **What do you dislike about Dfns?** They have incredibly detailed and expansive API capabilities, it can be overwhelming to jump in. **What problems is Dfns solving and how is that benefiting you?** As a payment infrastructure provider targetting non-blockchain native users, we need to create wallets for them and a UX that they are familiar with, as well as have significant capability to interact with existing products on the market. **Official Response from Christopher Grilhault des Fontaines:** > Thank you, Jasper! We are going to work harder on our SDKs to make Dfns easier to use and implement. ### 30. Excellent Features and Support with Continuous Improvements **Rating:** 5.0/5.0 stars **Reviewed by:** Zahra J. | Product Manager, Mid-Market (51-1000 emp.) **Reviewed Date:** October 22, 2025 **What do you like best about Dfns?** Great feedback loop that keeps improving the product Fast and helpful support team Valuable and practical features **What do you dislike about Dfns?** The dashboard is not very practical. Missing some useful APIs **What problems is Dfns solving and how is that benefiting you?** Enables interaction with the blockchain and provides wallets for both users and our company in a secure and easy to implement way. **Official Response from Christopher Grilhault des Fontaines:** > Thank you, Zahra! We hope to impress you with our next iteration of the dashboard coming up soon. Please keep feeding our product team with the missing APIs and we'll build them out this quarter. ### 31. User-Friendly, Informative, and Supported by a Diligent Team **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Small-Business (50 or fewer emp.) **Reviewed Date:** October 21, 2025 **What do you like best about Dfns?** Easy to use, amazing support, very informative documents and videos. Diligent and professional. Predictive pricing model. **What do you dislike about Dfns?** Does what it is supposed to do. Its strength is API first deployment, as its user base evolves, more UI functionality would be expected. **What problems is Dfns solving and how is that benefiting you?** Securing digital assets. **Official Response from Christopher Grilhault des Fontaines:** > Thank you so much! ### 32.

Best WaaS provider **Rating:** 5.0/5.0 stars **Reviewed by:** Teshank R. | Tech Lead, Small-Business (50 or fewer emp.) **Reviewed Date:** July 18, 2025 **What do you like best about Dfns?** Great support from the team. Easy to integrate APIs **What do you dislike about Dfns?** Due to high security, there are some problems with the user experience. **What problems is Dfns solving and how is that benefiting you?** Dfns takes care of wallet management and abstract the complexity that various blockchain holds **Official Response from Christopher Grilhault des Fontaines:** > Thank you, Teshank! You’re right. Security and frictionless experiences often pull in different directions. That said, our roadmap includes several features aimed at closing that gap. You should see steady improvements in the coming months. If you have suggestions for specific upgrades or changes, we’d love to hear them! ### 34. Solid product **Rating:** 5.0/5.0 stars **Reviewed by:** Nikola T. | Director, Small-Business (50 or fewer emp.) **Reviewed Date:** February 27, 2025 **What do you like best about Dfns?** It's a solid product for security minded builders in crypto with everything you need. The architecture and API are well thought-out, flexible and general. You can do everything with it! The team was also very responsive to our specific needs. **What do you dislike about Dfns?** Dfns still has to build out things around their core offering (like wallets for less popular chains) and do some UX polishing, but they have well-designed foundations. **What problems is Dfns solving and how is that benefiting you?** With Dfns we're moving away from single points of trust in our architecture. **Official Response from Christopher Grilhault des Fontaines:** > Thank you very much, Nikola! You're right, adding blockchains is a continuous area of improvement and we're glad to announce in the coming days support for Polymesh, Bittensor, Bitcoin Cash, Cardano and more. Regarding the dashboard, we're actually releasing a brand new one next month and would love to hear your feedback. We're convinced you'll appreciate it better than the current one. ### 35. Secure MPC wallet for corporate payments **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Financial Services | Mid-Market (51-1000 emp.) **Reviewed Date:** June 06, 2025 **What do you like best about Dfns?** API is clean and the product does what it says **What do you dislike about Dfns?** Still raw in terms of UX but glad to hear improvements are on the way **What problems is Dfns solving and how is that benefiting you?** Secure infra for corporate crypto **Official Response from Christopher Grilhault des Fontaines:** > Thank you!

Great product, great team! **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Financial Services | Mid-Market (51-1000 emp.) **Reviewed Date:** June 13, 2025 **What do you like best about Dfns?** Continually evolving the product with a responsive and accessible team. The two founders are great to work with! **What do you dislike about Dfns?** There is very little to dislike.

It means a lot. We went from 20 to 30 employee since January and expect to grow to 40-45 people (mostly engineers) in the next months. ### 37. A complete WaaS solution **Rating:** 5.0/5.0 stars **Reviewed by:** Milan A. | Co-Founder, Small-Business (50 or fewer emp.) **Reviewed Date:** May 10, 2024 **What do you like best about Dfns?** The integration of the dfns wallet infrastructure is super convenient. Anyone with basic knowledge of blockchain can implement their solution. The top-notch security of the dfns wallet saved us time and money so we could focus more on business development. Their solution gave us the flexibility to operate on multiple blockchains simultaneously and reduced our go-to-market time. Integrating these chains individually would have cost us a ton of manpower and money. Now dfns is the backbone of our product. Another thing we like is their expert support team. No matter our issue, these guys had a solution for everything. **What do you dislike about Dfns?** Dfns solutions meet our expectations however during the onboarding process, we faced certain delays but dfns handled those issues within due time. As an early customer of dfns, few development journeys were travelled together. **What problems is Dfns solving and how is that benefiting you?** DFNS provides MPC wallets to ScopeX customers, incorporating advanced biometric security features. Their private key securing mechanisms eliminated the operational complexity for users. This enhanced the user experience, which is the most challenging issue in adopting blockchain technology to the mass market. Dfns wallet infrastructure enables us to provide web3 services to web2 people seamlessly. **Official Response from Christopher Grilhault des Fontaines:** > Thank you, Milan! We appreciate your feedback and your engagement with Dfns. Your input helps us improve our product. We look forward to supporting ScopeX as you grow. ### 38. Great Product - Great Team - Great Integration **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Financial Services | Small-Business (50 or fewer emp.) **Reviewed Date:** June 30, 2025 **What do you like best about Dfns?** Easy to implement, really cool team, nice dashboard. **What do you dislike about Dfns?** List views on dashboard to ease the use of the dashboard. **What problems is Dfns solving and how is that benefiting you?** Giving wallets to our users. **Official Response from Christopher Grilhault des Fontaines:** > Thank you! Glad to read the dashboard is appreciated. We made a lot of efforts on it in the past 12 months and will continue to improve it. Views are a feature we'll develop during the second half of 2025. ### 39. DFNS offers exactly what web3 companies need **Rating:** 5.0/5.0 stars **Reviewed by:** David v. | Small-Business (50 or fewer emp.) **Reviewed Date:** May 16, 2024 **What do you like best about Dfns?** The signature/wallet service that DFNS offers is state of the art and exactly what most web3 companies need. Besides their excellent service and pricing, the team from DFNS really goes that extra mile in making sure that you get the right support with integrating their software but also in connecting with other parties that may be of value. We really feel we have a partnership with DFNS and not that we are just another customer. I can highly recommend DFNS. **What do you dislike about Dfns?** To be honest we haven't found one. We did a very thorough market research before selecting DFNS and since we have been using DFNS (at the time of writing this review for around 6 months) it not only fulfilled our expectations but also exceeded them. This is mainly due to their excellent support which is obviously very hard to judge when comparing various companies beforehand. **What problems is Dfns solving and how is that benefiting you?** We have a platform on which we tokenize our assets. With DFNS we create wallets for our users so that they don't have to create a non-custodial wallet and can directly invest in our tokenized assets. **Official Response from Christopher Grilhault des Fontaines:** > Thank you, David! Our team is very grateful for your feedback, which means a lot. ### 40. A true enabler for the web3 space and a wonderful team **Rating:** 5.0/5.0 stars **Reviewed by:** Peter B. | Board Member (Blockchain Developer Program), Small-Business (50 or fewer emp.) **Reviewed Date:** May 09, 2024 **What do you like best about Dfns?** Their product solves a significant problem in Web3's path towards mainstream adoption: providing secure keyless wallets that anyone can use. They have a really strong team, both on the tech and the business side, along with excellent support and a clear roadmap, and they always provide helpful easy to understand introductions to all updates they ship. You can feel that they really want you to succeed in what you are buidling, and they are always there to help and share knowledge. **What do you dislike about Dfns?** Nothing I can think of. Really enjoy their new blog as well. **What problems is Dfns solving and how is that benefiting you?** Web3 is growing even faster than the Internet did in its early days, but one significant hurdle remains: wallet security. Consider the concept of individuals becoming their own bank and managing their own security, only to be asked to rely on 12 words written on a piece of paper. Dfns remove the keys while still empowering users with control. They make it possible to establish different rules, making it easy to adapt whether for individual users or organizations. In case of lost access, the system itself can facilitate recovery, so no need for any centralized intermediaries. During our benchmarking of various wallets, one standout feature was the ability to withdraw access in a multisig setup. This means that even if an employee has the ability to sign transactions, access can be revoked upon their departure. This capability is unique and is crucial for organizations, as the need for this feature will inevitably arise. **Official Response from Christopher Grilhault des Fontaines:** > Thank you, Peter! Your feedback means a lot. ### 41. Been using Dfns for over a year, it's a great product, I can only recommend it **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Financial Services | Small-Business (50 or fewer emp.) **Reviewed Date:** March 24, 2025 **What do you like best about Dfns?** Ease of integration, reliability and customer support. **What do you dislike about Dfns?** Nothing, our experience has been great so far. **What problems is Dfns solving and how is that benefiting you?** Dfns solves the creation of wallets via API in our technical stack. **Official Response from Christopher Grilhault des Fontaines:** > Thank you! ### 42. The best wallet-as-a-service that I have tried **Rating:** 5.0/5.0 stars **Reviewed by:** Alexandre C. | CEO, Financial Services, Small-Business (50 or fewer emp.) **Reviewed Date:** May 11, 2024 **What do you like best about Dfns?** I have tried several Wallet-as-a-Service (WaaS) platforms, both self-custodial and custodial, and DFNS stands out as one of the most flexible in this field. For example, you can craft your transactions exactly as you want. Although this might add complexity for some, my team and I greatly prefer this approach. The documentation is well written and simple to understand. Their team is always there to answer any questions you may have. DFNS provides everything you need to effectively manage your digital assets. **What do you dislike about Dfns?** Nothing to complain about for now. If there are features missing, they will implement them quite quickly. **What problems is Dfns solving and how is that benefiting you?** We needed audited, flexible, and future-proof software to manage our digital assets (Bitcoin and others). After trying and discussing many platforms, we settled on DFNS. **Official Response from Christopher Grilhault des Fontaines:** > Thank you, Alexandre! ### 43. Powerful Web2 Onboarder **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Small-Business (50 or fewer emp.) **Reviewed Date:** September 02, 2024 **What do you like best about Dfns?** The flexibility of the product to adapt to all necessities and the great help and responsiveness of the DFNS team **What do you dislike about Dfns?** Documentation is a bit chaotic both for API and SDK. I'd provide less examples and more structured topic learning. **What problems is Dfns solving and how is that benefiting you?** Web2 users don't know what a crypto wallet is and the main bottleneck for blockchain adoption is how rapid and easy the web3 onboarding is. DFNS uses latest cutting edge security and cryptogrsphy patterns with a comprehensive solution. **Official Response from Christopher Grilhault des Fontaines:** > Thank you! Improving the developer experience is our top priority. We'll be making significant updates to our API documentation in the coming weeks and months. ### 44. Had an amazing experience using DFNS wallet management system **Rating:** 5.0/5.0 stars **Reviewed by:** Teshank R. | Software Engineer 1, Small-Business (50 or fewer emp.) **Reviewed Date:** May 15, 2024 **What do you like best about Dfns?** The wallet creation and management system is so well taken care of by dfns that we don't have to worry about the security of the wallets, they provide an simple API hiding all the complexity. **What do you dislike about Dfns?** Their typescript docs is not very helpful. **What problems is Dfns solving and how is that benefiting you?** DFNS is taking care of underlying complexities and security behind blockchain wallets and providing with a simple endpoint to interact with, which makes development from our side faster. **Official Response from Christopher Grilhault des Fontaines:** > Hey Teshank! Thank you very much for the positive feedback. Let us know via email or chat what specifically about the Typescript SDK is not helpful enough and we will do our best to adjust the descriptions and guidelines within the docs. ### 45. Dfns offers top notch customer service and integration support **Rating:** 5.0/5.0 stars **Reviewed by:** Mitul M. | Mid-Market (51-1000 emp.) **Reviewed Date:** May 10, 2024 **What do you like best about Dfns?** The Dfns team consistently demonstrates a positive and collaborative approach.

Dfns provides the wallet infrastructure for us **Official Response from Christopher Grilhault des Fontaines:** > Thank you, Mitul! ### 46. Excellent MPC Infrastructure **Rating:** 5.0/5.0 stars **Reviewed by:** Luke T. | Small-Business (50 or fewer emp.) **Reviewed Date:** May 09, 2024 **What do you like best about Dfns?** - Extremely flexible infrastructure - Affordable pricing for large scale usage - Broad, multi-chain support - Quick and effective issue resolution - Helpful integration guides **What do you dislike about Dfns?** - Expensive for low volume use - Limited Rust Support **What problems is Dfns solving and how is that benefiting you?** We need the ability to offer keyless wallets to our users in a flexible and multi-chain manner, that allows for complex user actions and gives us full control over the user experience and authentication schemas. **Official Response from Christopher Grilhault des Fontaines:** > Thank you for the feedback, Luke! The Rust SDK is on our near-term roadmap and we'd be happy to discuss a new pricing structure that works better for you. ### 47. Gamechanging for those that are serious about wallet solutions **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.) **Reviewed Date:** May 07, 2024 **What do you like best about Dfns?** Team is awesome. Product does what it should. It has been a pleasure to work with them. They are responsive, sharp, and have gone above and beyond to help us out. Easy to use. Easy to integrate/implement. We use dfns daily, and there are a lot of features. **What do you dislike about Dfns?** Only complaint is that certain virtual machines have more robust support than others. But this shouldn't really matter if you know your way around the less supported ones. **What problems is Dfns solving and how is that benefiting you?** We need to issue customers custodial wallets so that way they control their funds. dfns is that in an API. **Official Response from Christopher Grilhault des Fontaines:** > Thank you sincerely for your heartfelt feedback! Just to inform you: Our Transaction Broadcasting API empowers any feature within any virtual machine (VM) to access bespoke functionalities through the native blockchain SDK. For further details, please refer below. ### 48.

Our mission is to offer peace of mind to application developers who rely on Dfns for their projects. While most of our informative videos and educational content can be found in our API documentation (https://docs.dfns.co), additional resources are available in our data room (see below). ### 49.

Ninja environment and the Postman collection are very useful. In production the service works well. **What do you dislike about Dfns?** The dashboard. It is very simple, that is good, but sometimes we need more options like filtering wallets, download transaction history and custom the fee for transactions. **What problems is Dfns solving and how is that benefiting you?** DFNS helps us to provide recharges in USDT. **Official Response from Christopher Grilhault des Fontaines:** > Thank you sincerely for your review. Over the past four years, Dfns has dedicated itself to crafting the most robust and secure wallet APIs on the market. While our primary focus has been on functionality, the user interface (UI) has remained secondary.
