metamask/tkey-tss

tKey is a TypeScript-compatible SDK for managing private keys using Shamir Secret Sharing, allowing developers to implement threshold key management in their applications. It enables secure storage and retrieval of cryptographic keys by splitting them into shares across multiple locations, such as user devices, OAuth providers, and recovery mechanisms. This project is designed for developers building Web3 applications who want to self-host Web3Auth's authentication system or integrate advanced key management features into their own systems.
