CYBAVO

CYBAVO was a digital asset security company (founded 2018, Taipei/Singapore) providing institutional-grade cryptocurrency custody and wallet infrastructure. Its flagship CYBAVO Vault delivered MPC-based (Multi-Party Computation) custody with a policy/workflow engine, REST API, and client SDKs, alongside the CYBAVO Wallet App SDK for embedding secure private-key storage into mobile apps. Circle Internet Financial acquired CYBAVO in June 2022; the team and technology became the foundation of Circle Web3 Services and Circle Programmable Wallets. The cybavo.com developer surface has since been wound down (redirects to circle.com), but the first-party @cybavo Wallet/Auth SDKs remain published on npm and are maintained under Circle's circlefin GitHub organization.

CYBAVO is profiled on the APIs.io network. Tagged areas include Company, Cryptocurrency, Digital Asset Security, Wallet, and Custody.
