# Dfns Reviews **Vendor:** Dfns **Category:** [Cryptocurrency Custody Software](https://www.g2.com/categories/cryptocurrency-custody) **Average Rating:** 4.8/5.0 **Total Reviews:** 34 ## About Dfns DFNS is a core banking platform for digital assets. 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 commend the **responsive and knowledgeable customer support** of Dfns, enhancing their integration experience significantly.

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. ### 2. 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. ### 3. 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. ### 4. 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. ### 5. 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. ### 6. 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. ### 7. Nimble, Responsive and Easy Integration **Rating:** 4.5/5.0 stars **Reviewed by:** Anoosh A. | Chief RIsk Officer, Mid-Market (51-1000 emp.) **Reviewed Date:** October 13, 2025 **What do you like best about Dfns?** I appreciate Dfns for its nimble team and easy API integration, which facilitates seamless project delivery for my firm. 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! ### 8. 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! ### 9. 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. ### 10. 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. ### 11. 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. ### 12. 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. ### 13. 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! ### 14. Transparent Pricing and Clear Dev Docs Make It Stand Out **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.) **Reviewed Date:** October 24, 2025 **What do you like best about Dfns?** transparent pricing, clear dev docs, responsive team **What do you dislike about Dfns?** N/A, full implementation not yet carried out **What problems is Dfns solving and how is that benefiting you?** custody tech infrastructure, speed (instant generation of deposit addresses), and breadth (number of networks) and depth (supported assets, e.g., NFTs) of coverage **Official Response from Christopher Grilhault des Fontaines:** > Thank you! ### 15. 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! ### 16. 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. ### 17. 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! Indeed, though historically we have always been API-firs, we have reinforced our frontend engineering team to improve the dashboard and build a mobile app for Q3 2025. We'll keep you posted on the next updates. ### 18. 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. Speed and scale of execution is always an issue but it's understandable given the size of the business. **What problems is Dfns solving and how is that benefiting you?** More reactive than other providers with the ability to influence and collaborate on road map items **Official Response from Christopher Grilhault des Fontaines:** > Thank you for your feedback! 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. ### 19. 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. ### 20. 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. ### 21. 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. ### 22. 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. ### 23. 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! ### 24. 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! ### 25. 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. ### 26. 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!
