What?

BOB is building the Gateway to Bitcoin DeFi, unlocking real utility for the world’s most important asset. By fusing Bitcoin’s unmatched security with Ethereum’s versatility, BOB creates the premier destination for Bitcoin liquidity, applications, and institutions.

BOB’s hybrid chain uniquely combines ZK proofs and BTC staking to create native bridges to both Ethereum and Bitcoin (BitVM). BOB’s multichain gateway lets users swap Bitcoin into any asset or deposit directly into DeFi across 14+ chains, powered by BTC intents.

With $200M+ TVL, 540K users, and tier 1 DeFi and institutional partners such as Uniswap, Chainlink and Fireblocks, BOB has already established itself as the leading hub for Bitcoin DeFi.

BOB has raised $21M from Castle Island, Coinbase, Ledger, major BTC miners and angels from Aave, Curve, GMX & more.

Why?

• Hybrid of Bitcoin and Ethereum: A hybrid ZK rollup on Ethereum, secured by billions of dollars of staked BTC, BOB will be the first chain to have finality from both Ethereum and Bitcoin.
• Multi-chain BTC gateway: Powered by BTC intents, BOB lets users swap Bitcoin into any asset or deposit directly into DeFi across 14+ chains.
• Non-custodial BTC bridge: Powered by BitVM and protected by Bitcoin’s security guarantees, BTC on BOB will be BTC - with no need for wrappers.
