# Fystack

> An enterprise-grade digital asset custody platform for teams

Fystack helps developers create secure wallets by providing MPC infrastructure that distributes key fragments across multiple nodes.

Fystack provides MPC wallet infrastructure that lets developers eliminate single points of failure in key management. Developers can integrate wallet generation, smart contract deployment, and crypto payment flows into their applications. The distributed key architecture reduces security risks compared to centralized key storage approaches.
