Easy to use, amazing support, very informative documents and videos. Diligent and professional. Predictive pricing model. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

Great support from the team.

Easy to integrate APIs Review collected by and hosted on G2.com.

What do you dislike about Dfns?

Due to high security, there are some problems with the user experience. Review collected by and hosted on G2.com.

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!

"Solid product"

5/5

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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

Response from Christopher Grilhault des Fontaines of Dfns

edit

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.

Continually evolving the product with a responsive and accessible team. The two founders are great to work with! Review collected by and hosted on G2.com.

What do you dislike about Dfns?

"A complete WaaS solution"

5/5

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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

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.

Easy to implement, really cool team, nice dashboard. Review collected by and hosted on G2.com.

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.

"DFNS offers exactly what web3 companies need"

5/5

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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

"A true enabler for the web3 space and a wonderful team"

5/5

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. Review collected by and hosted on G2.com.

What do you dislike about Dfns?

Nothing I can think of. Really enjoy their new blog as well. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.
