Dfns

4.2/5 3.9/5 · Data verified on

Dfns is an API-based wallet-as-a-service platform for developers, fintechs and regulated institutions. It uses multi-party computation (MPC) and threshold signature schemes: private keys are never reassembled in one place and the client institution retains full control, so Dfns does not act as a custodian of funds. Founded in Paris in 2020, it reports over 400 banks, fintechs and institutions and more than 20 million managed wallets.
