BOB is a unique Hybrid Layer 2 that combines Bitcoin’s security with EVM smart contracts. Powered by BitVM, it enables BTC to be deployed into DeFi in a trust-minimized way. BOB also operates BTC-secured bridges to Ethereum and other chains, providing BTC holders with the most secure and decentralized access to Bitcoin DeFi products. The Hybrid model has been designed to merge the strengths of Bitcoin and Ethereum, fusing Bitcoin's security and capital with Ethereum's DeFi innovation and versatility. By placing BTC at the heart of DeFi, BOB can unlock new use cases and trillions in liquidity. This makes BOB the ideal home for Bitcoin DeFi - the best and safest place to earn yield on your Bitcoin. BOB is bootstrapped as an ETH rollup, member of the OP Superchain, and actively working on BitVM2 as co-authors of the official technical blueprint. Through the hybrid design and BitVM2, BOB will have trustless bridges to BTC as well as ETH and other L1s, secured by Bitcoin.
