BOB is a hybrid Ethereum Layer 2 network that fuses the security of Bitcoin with the programmability and DeFi innovation of Ethereum. Built on the OP Stack, BOB initially operates as an optimistic rollup on Ethereum, but is evolving to inherit Bitcoin-level security through BTC staking and BitVM-powered trust-minimized bridges. Users can deposit BTC and interact with DeFi apps using EVM smart contracts, with all critical operations and settlements anchored to Bitcoin for maximum security. The platform enables seamless, trustless BTC deposits, supports Bitcoin-native assets (like Runes, Ordinals, BRC20s), and provides state-of-the-art EVM infrastructure, making it easy for both Ethereum and Bitcoin developers to build and deploy dApps.
BOB’s security is anchored in Bitcoin’s proven consensus. Through BitVM2, every state transition is validated and published to Bitcoin L1, with a fault-proof mechanism that allows any participant to challenge incorrect operations—requiring only one honest node for network integrity. The trust-minimized bridge design means users don’t rely on multisig or centralized custodians. As BOB’s phased rollout progresses, BTC staking and Bitcoin finality will secure not just the network, but also all cross-chain bridges and DeFi transactions.
Users can connect an EVM-compatible wallet, bridge BTC or ETH to BOB via its native bridges, and interact with DeFi protocols, staking, and vaults on the network. Developers can deploy Solidity smart contracts using familiar Ethereum tools, access Bitcoin transaction data, and utilize the BOB SDK for building hybrid dApps. BOB supports both Bitcoin and Ethereum wallets, enabling fast onramps for BTC, stablecoins, and ERC20s, and provides developer resources for full node operation and smart contract deployment.
BOB offers trustless BTC deposits, cross-chain asset transfers, hybrid BTC vaults for staking and yield, access to both Bitcoin and Ethereum DeFi, and support for innovative Bitcoin-native assets. The platform enables one-click Bitcoin DeFi participation, developer tooling for EVM and Bitcoin apps, and secure, trust-minimized bridges. BOB also features a dual-liquidity model, aggregating liquidity from both Bitcoin and Ethereum, and is a member of the OP Superchain for broad interoperability and ecosystem support.
