BitcoinOS (BOS) is building a suite of developer and institutional tools that enable Bitcoin to function as a programmable foundation for digital economies. The company achieved a milestone by verifying the first zero-knowledge (ZK) proof on Bitcoin’s mainnet, opening the door to smart-contract-like functionality without altering the core protocol. Its product roadmap includes Grail Pro, an institutional-grade BTC yield protocol now in pilot with custodians, and trustless bridges that connect Bitcoin liquidity to other chains such as Ethereum and Cardano. BOS positions itself within the emerging Bitcoin DeFi (BTCFi) sector, aiming to unlock Bitcoin’s deep liquidity for broader financial use cases. The newly raised capital will fund the scaling of its developer infrastructure and continued rollout of institutional products.
