What is BOB?
The Vision: Putting Bitcoin at the Heart of DeFi
Bitcoin represents the world's largest and most valuable digital asset, yet it remains largely untapped in DeFi. While Ethereum has achieved ~30% DeFi TVL penetration, Bitcoin sits at just 0.3%. BOB exists to bridge this gap, giving everyone access to Bitcoin's potential.
The Problem: Users and institutions want sustainable returns on their Bitcoin holdings, while projects and apps need liquidity in the world's most trusted asset.
The Solution: BOB - The Gateway to Bitcoin DeFi
BOB combines the security of Bitcoin with the DeFi innovation of Ethereum, creating the best place to build and earn yield with BTC.
For Users: 1-click Bitcoin staking, cross-chain BTC swaps, and seamless DeFi access
For Developers: "Integrate BOB EVM, get native BTC access"
Key Innovation: "BTC on BOB is BTC" - The first chain to achieve finality from both Ethereum and Bitcoin.
The Technology: The Hybrid Chain
BOB is an optimistic rollup with ZK proofs on Ethereum secured by billions of dollars of staked Bitcoin, serviced by a hybrid BitVM bridge for native BTC integration.
Core Architecture
Bitcoin Security: BTC on BOB is protected by Bitcoin's security model via BitVM
Ethereum Compatibility: Full EVM compatibility with ZK fraud proofs
Hybrid Finality: Finality secured by both Bitcoin and Ethereum networks
