BitGoJS

BitGoJS is a JavaScript SDK for developers building applications that require secure multi-signature cryptocurrency wallet management, key generation, and transaction signing. It is designed for blockchain developers and fintech teams who need to integrate BitGo’s enterprise-grade custody and security infrastructure directly into their own software. The project is interesting because it abstracts complex, high-assurance cryptographic operations into a simple API, enabling non-custodial and institutional-grade digital asset management without building security from scratch.
