What is BOB (Build on Bitcoin)?

BOB (Build on Bitcoin) is a Hybrid Layer 2 (Hybrid L2) blockchain solution that inherits security from Bitcoin. Its goal is to combine Bitcoin’s security with Ethereum’s flexibility to create a premier liquidity and application hub for both users and institutions. BOB offers a unique hybrid chain model that merges Bitcoin staking with ZK proofs and establishes native bridges between Bitcoin and Ethereum.

BOB allows users to deposit Bitcoin into DeFi applications or swap it into other assets across more than 11 blockchains with a single click. This ensures fast, secure, and low-cost Bitcoin transactions for both individual investors and institutions.

Team and Founders

Key visionaries and authors of BOB’s Vision Paper include:

• Alexei Zamyatin

• Dominik Harz

Investors and Partners

BOB maintains strong financial and technological partnerships. Corporate partners include Fireblocks, Cobo, and ForDeFi, while top DeFi protocols such as Solv, Xverse, Pell, and Sovryn have integrated BOB into their ecosystems.

Project Concept

Although Bitcoin is the world’s most valuable digital asset, its penetration in DeFi is extremely low (~0.3%), whereas Ethereum has ~30% of DeFi TVL. BOB’s mission is to unlock Bitcoin’s DeFi potential, providing sustainable returns and liquidity for both users and projects.

Core Idea: BOB brings Ethereum’s EVM (Ethereum Virtual Machine) compatibility and smart contract capabilities to the Bitcoin ecosystem, centralizing Bitcoin liquidity in a single DeFi ecosystem rather than scattering it across multiple chains.

How the Project Works

BOB combines Bitcoin security with Ethereum flexibility through a hybrid chain. BitVM bridges allow users to deposit, stake, or swap BTC in a single transaction. The hybrid chain model ensures that all transactions are verified by both Bitcoin and Ethereum networks.

• Hybrid Chain Model: Combines Bitcoin security (BitVM2) with Ethereum flexibility.

• BTC Staking: Users can stake BTC with one click to earn DeFi yields.

• Multichain Gateway: BTC can be swapped or deposited into DeFi on 11+ chains.

• Trustless Bridges: BTC deposits and withdrawals are secure without relying on bridge operators.

• Hybrid Vault: Tokenized BTC yields optimized with institutional security and strategies.

• Ethereum & L1/L2 Integration: Trustless bridges secured by Bitcoin allow DeFi usage across multiple chains.

Governance

The BOB ecosystem has a decentralized governance model. Users, token holders, and BitVM partners can contribute to protocol development, ensuring both security and transparency.

Roadmap

End of 2025:

• $BOB token and DAO launch (completed)

• Hybrid yield vaults (BTC-native earning products)

• BOB Gateway multichain swaps (expansion to 11+ chains)

2026:

• BitVM2 integration (rollup and bridge optimizations)

• Enterprise BTCFi tools (via bitvm/acc alliance)

• Additional chain integrations and native lending expansion

Note: The mainnet launched 18 months ago, aiming for Bitcoin Summer initiatives.

BOB Token

• Total Supply: 10,000,000,000 BOB

• Max Supply: 10,000,000,000 BOB

• Circulating Supply: 2,220,000,000 BOB

Token Allocation:

• Ecosystem & Community: 44.76% (14.6% unlocked at TGE, remainder over 48 months)

• Initial Claims & Staking Bonuses: 4.15%

• Community Sale: 2%

• Foundation: 10% (2.5% TGE, 7.5% linear unlock over 4 years)

• Core Contributors: 19%

• Early Backers: 20.09%

Token Locking & Unlocking:
77.8% of total supply is locked at launch. Locked tokens cannot be staked; only active users and community participants receive staking rewards. Full supply unlocks 48 months after the token launch.

Token Utility

• Staking & Economic Security: BOB tokens can be staked on Hybrid Nodes to provide Bitcoin finality and operate BitVM, earning higher fee shares.

• Decentralized Governance: Both staked and unstaked tokens can participate in BOB DAO governance. Users can vote directly or delegate their vote to governance delegates.

• Protocol Benefits: Token holders get priority access to new features like BOB Earn and BOB Gateway DeFi strategies.

Revenue Models & Buyback Programs

• Sequencer Fees & MEV: Fees from DEX rebalancing and liquidations scale with network activity.

• BOB Gateway Swap Fees: Native BTC swaps generate revenue, increasing as swap volume grows.

• Hybrid Vaults: BTC yield vaults combine on-chain and off-chain strategies to produce performance fees.

• Native BTC Lending & Liquidations: BTC-collateralized borrowing of stablecoins generates revenue from lending demand and liquidations.

• DAO Buyback Program: As protocol revenue grows, BOB DAO may implement structured buybacks to reward participants securing and staking the system.

Ecosystem and Partners

BOB integrates tier 1 DeFi protocols including Uniswap, Euler, Aave, LiFi, Lombard, Chainlink, Babylon, and Solv. Corporate partners include Fireblocks, Cobo, and ForDeFi, supporting rapid ecosystem growth.

Features

• Hybrid Chain Model: Secures transactions with ZK proofs and Bitcoin staking.

• Multichain Gateway: Single-click BTC DeFi access and cross-chain swaps.

• Hybrid Vault: Institutional-grade tokenized BTC yields.

• BitVM Security: First solution providing full finality on Bitcoin.
