About BOB 

BOB (Build on Bitcoin) is a pioneering hybrid Layer-2 blockchain that bridges the robust security and liquidity of Bitcoin with the innovative decentralized finance (DeFi) ecosystem of Ethereum. Launched as the "Gateway to Bitcoin DeFi," BOB aims to unlock the full potential of Bitcoin, the world’s largest and most trusted digital asset, by enabling seamless, secure, and user-friendly access to DeFi opportunities. With a mission to onboard the next billion users to Bitcoin DeFi, BOB combines Bitcoin’s unparalleled security—backed by billions of dollars of staked BTC—with Ethereum’s versatile EVM (Ethereum Virtual Machine) infrastructure to create a unique hybrid chain.Founded by a team of innovators, including co-founder and BitVM researcher Alexei Zamyatin, BOB is at the forefront of revolutionizing how Bitcoin holders can earn yield on their assets.  

The company’s flagship product, the BOB Gateway, simplifies the user experience by allowing BTC holders to stake, swap, or lend their Bitcoin through a single, unified interface, leveraging trustless cross-chain swaps and Bitcoin intents. BOB’s hybrid model integrates advanced technologies like BitVM for trustless BTC deposits and Zero-Knowledge (ZK) proofs to enhance efficiency and security, positioning it as a leader in the Bitcoin DeFi space.BOB has raised $21 million in strategic funding rounds since December 2024, backed by prominent investors such as Castle Island Ventures, Coinbase Ventures, Ledger Cathay Capital, and others, reflecting strong confidence in its vision to tap into Bitcoin’s $750 billion latent capital opportunity. The company collaborates with top-tier DeFi protocols and institutions, including Uniswap, Euler, Chainlink, Fireblocks, and Lombard, to build a robust ecosystem that supports staking, lending, yield farming, and cross-chain asset swaps.  

As a member of the OP Superchain and powered by the OP Stack, BOB offers developers a cutting-edge playground to build at the intersection of Bitcoin and Ethereum, with full EVM compatibility and state-of-the-art tooling.BOB’s vision is to make Bitcoin DeFi accessible, secure, and efficient, addressing the gap where only 0.3% of Bitcoin’s total value is currently utilized in DeFi compared to Ethereum’s 30%. By providing 1-click DeFi solutions and trustless bridges to major chains, BOB is poised to unlock trillions in liquidity and drive mass adoption of Bitcoin in decentralized finance.
