"The best wallet-as-a-service that I have tried"
5/5
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. Review collected by and hosted on G2.com.

What do you dislike about Dfns?

Nothing to complain about for now. If there are features missing, they will implement them quite quickly. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

Response from Christopher Grilhault des Fontaines of Dfns

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. However, we've recently dedicated resources to completely revamp our dashboard, aligning it seamlessly with our APIs. Below, you'll find a click-through demo providing a sneak peek into the look and feel of the new UI. We are confident that this updated dashboard will cater to all your needs and will continue to evolve and improve over time.
