Bridging Bitcoin and Ethereum
BOB uses the hybrid chain model, which combines the security and stability of Bitcoin with the versatility of Ethereum’s DeFi ecosystem.
BOB is a hybrid because it is simultaneously a member of the Superchain, leveraging the OP Stack as an Ethereum rollup, and also a Bitcoin-secured network, integrating with Babylon for Bitcoin finality via billions of dollars of staked BTC.
As of Aug. 7, 2025, BOB’s total value locked is $212 million, DeFi TVL is $132.2 million, with 553,000 users.

Native Bitcoin DeFi is on the way
Previously, Bitcoin DeFi largely relied on centralized institutions or wrapped Bitcoin tokens such as wBTC, tBTC, and Huobi BTC. These so-called “Bitcoin” tokens were representations of real BTC, where users deposited their genuine BTC with a centralized or multisignature custodian in exchange for a tokenized version that could be used on-chain.
While all BTC bridges have historically relied on multisignature custody, BOB’s BitVM2 allows users to interact with DeFi applications using their native BTC directly—no custody, no wrapping required.
BitVM2 is the latest BitVM design, co-authored by BOB co-founder Alexei Zamyatin. It enables practical fraud proofs on Bitcoin, which allows users to enforce trust-minimized bridging between the Bitcoin L1 and BOB.
By leveraging this technology, BOB aims to bring Bitcoin closer to Ethereum-style decentralized finance, allowing Bitcoin users to engage in DeFi without losing control of their assets. The network aims to preserve Bitcoin’s security while enabling interaction with Ethereum-based DeFi protocols.
