About Us

Dfns is a cybersecurity company providing crypto wallet infrastructure. Founded in August 2020, Dfns was incubated by Techstars and STATION F before becoming a SOC 2 Type II certified firm audited by Deloitte. Built by a team of PhDs and experts in security and cryptography, Dfns is leading research in threshold signatures applied to keys.

Dfns develops the most secure wallet-as-a-service infrastructure in Web3. It’s a developer-friendly wallet management system, ideal for applications and organizations seeking to provide secure access to all blockchains through a single integration. Our APIs and SDKs were designed for wallet programmability and efficient implementations, enabling fast deployments, smart automation flows, as well as granular sets of permissions and policies via secure authentication credentials.

Since 2020, Dfns has helped ABN AMRO, Fidelity, Zodia and many others create over a million wallets. We’ve raised over $25M with White Star Capital, Motive, ABN AMRO, Bpifrance, Coinbase, Semantic, Wintermute, Figment, Motier Ventures, Hashed, 6MV, Susquehanna and others.
