BOB ("Build on Bitcoin" / "The Bank of Bitcoin"), operated by BOB Labs Inc., runs a hybrid chain that combines Bitcoin security with EVM programmability. The network is built on the OP stack, is a member of the OP Superchain, has a native ETH bridge, and uses ETH as its gas currency (mainnet chain ID 60808; test network BOB Sepolia, chain ID 808813). The company describes four core chain properties: full EVM opcode compatibility, rollup security via hybrid ZK fault proofs, Bitcoin finality secured by staked BTC, and a BitVM-based native BTC bridge that avoids custodians and wrapped assets.

A second product line, BOB Gateway, provides one-click swaps between native BTC and other assets and direct deposits into DeFi positions using a single Bitcoin transaction. The company states the Gateway SDK gives 15,000 dapps across 11 chains access to native BTC, supports on- and off-ramps from connected chains including BNB, Base, Unichain, Sonic and Avalanche using LayerZero, and allows onboarding directly from centralized exchanges and hardware wallets. BOB also offers a vault layer packaging tokenized BTC yield strategies with institutional curators and custodians, and invites institutions to run "hybrid nodes" responsible for Bitcoin finality provision, BitVM bridge operation, block building and Gateway solving.

BOB positions Bitcoin DeFi as an underpenetrated market, stating that roughly 0.3% of Bitcoin's market capitalization is used in Bitcoin DeFi versus about 30% for Ethereum, framing a $750B opportunity. In research and standards work, BOB says it co-authored the BitVM2 paper on Bitcoin rollups and bridges, founded the bitvm/acc working group for BitVM builders and Bitcoin institutions, and developed a model for managing native Bitcoin lending liquidations.

Business model

Latest developments

In November 2025 BOB Labs announced the $BOB token (10,000,000,000 total supply) with staking, governance and utility functions, and a community sale offering up to 4% of supply (400,000,000 tokens) across a general public tranche at $230M FDV and a community-member tranche at $165M FDV, with terms updated on 12 November to accelerate vesting. The sale ran 10-16 November 2025, accepted USDC and USDT, and had bid limits of $50 to $250,000. A BOB DAO is planned to launch on day one of the token generation event. A third-party dataset also records a November 2025 partnership with Anchorage Digital.
