Welcome to BOB, the home of Bitcoin DeFi

BOB is the first Bitcoin Layer-2 on the Superchain, giving users of the new ecosystem easy and secure access to BTC DeFi. BOB’s Hybrid L2 model combines the best of Bitcoin and Ethereum, merging Bitcoin's security and dormant capital with Ethereum's innovation and user base.

BOB’s unique approach uses BitVM to inherit security from Bitcoin and create trust-minimized bridges between BOB, Bitcoin, Ethereum, and other L1s. As a result, the Hybrid L2 does not need to rely on third-party bridges for interoperability, concentrating liquidity around Bitcoin instead of fragmenting it across chains.

With an ecosystem of 100+ projects live or building, including Uniswap, Solv & Sovryn. BOB has successfully captured the growing interest in Bitcoin staking and yield-bearing assets:

  • Launched 1-click BTC staking powered by Bitcoin Intents
  • Achieved ∽$250m in DeFi TVL
  • Recruited 180k unique users since launch in May 2024.
  • BOB supports decentralized tBTC as well as institutional wBTC, FBTC and SolvBTC as BTC bridges, as well as numerous Bitcoin LSTs like SolvBTC.BBN, UniBTC and PumpBTC.

Whether you’re a builder or a user, BOB makes Bitcoin DeFi simpler and more accessible than ever.
