Dfns is the most secure wallet-as-a-service infrastructure in Web3. Dfns offers an API-first wallet management system designed to provide application developers with secure, plug-and-play access to all blockchains. We designed the product with focus on developer experience to maximize programmability, minimize high-touch implementations, and provide granular sets of permissions, controls and policies via secure API credentials.The core security model of Dfns is based on a decentralized, MPC-driven key management network with built-in threshold recovery mechanisms. Dfns Labs is the PhD-led cryptography team that is pushing the boundaries of decentralized and trustless key management systems by making multi-party computation and threshold-based protocols more scalable, robust, and accountable.
