Dfns

Dfns is a programmable wallet-as-a-service infrastructure (MPC/TSS wallets) for fintechs, banks and payment platforms. The company is based in Paris, France and New York, United States, and was founded in 2020. Through the Dfns API, a business creates wallets, manages keys and signs transactions without building its own custody system.

What the service provides - API-first MPC wallets for customers or internal use; - Passkeys and biometric authentication; - a Policy and Governance Engine; - a Gas Station that sponsors network fees; - support for 40+ networks.

Secure key storage and signing is the hardest part of crypto infrastructure, and a ready-made service lets the team embed on-chain features directly into a financial app.

Clients Target customers are fintechs, PSPs, stablecoin apps, neobanks and exchanges. According to the company, Fidelity and Bridge are among its users.

Limitations and pricing The service covers the on-chain side. Linking it to fiat, such as bank top-ups, withdrawals and conversion, requires extra integrations with partners. Pricing is a modular SaaS subscription based on the number of wallets and signatures.
