What Build on Bitcoin does
Build on Bitcoin (BOB) operates a hybrid Layer-2 blockchain that combines Bitcoin's security and finality with Ethereum Virtual Machine compatibility. Founded in 2023 by ex-Imperial College London PhDs Alexei Zamyatin and Dominik Harz, the company is incorporated in the British Virgin Islands as Bob Labs, Inc. and operates from London. The protocol is built on the OP Stack and uses hybrid ZK fault proofs; its trust-minimized BitVM Bridge enables native BTC deposits and withdrawals without wrappers or third-party custodians, while Bitcoin finality is delivered via staked BTC on Hybrid Nodes. The core product portfolio comprises the BOB Hybrid Chain (the L2 itself), the BOB Gateway SDK (a Bitcoin intents toolkit giving 15,000+ dapps on 11 chains 1-click native BTC deposits and cross-chain swaps via LayerZero), BOB Earn (1-click staking, DeFi and vault strategies), the Bitcoin Vaults Liquidation Engine, and the $BOB native token (10 billion fixed supply, launched November 2025). The platform serves four overlapping segments: retail Bitcoin holders seeking DeFi yield, EVM developers wanting Bitcoin-secured infrastructure, institutional digital-asset players (accessed via Fireblocks and Anchorage), and dapp/protocol partners integrated through the Gateway SDK and Uniswap, Solv, Chainlink, Babylon, Bedrock, and Pell.
BOB's go-to-market combines product-led growth (the self-serve app.gobob.xyz application), community-led growth through the BOB Fusion program, Spice and Cookie Snapping community sales, and DAO governance, supplemented by event-driven DeFi campaigns with Optimism (BOB Rise, 750,000 OP tokens) and Binance Web3 Wallet quests. Revenue is generated at the protocol layer through sequencer fees and "good MEV" from DEX rebalancing and liquidations, Gateway swap fees for cross-chain BTC interoperability, Hybrid Vault performance fees, and fees from the native BTC lending and liquidation engine. The company has raised $21M+ across a $10M seed led by Castle Island Ventures (March 2024), a $1.6M angel round led by Ledger Cathay (July 2024), and a $9.5M strategic round at a $300M post-money valuation (August 2025), with a $4.2M community token sale completing in November 2025 alongside the launch of the BOB DAO.

Revenue model
- Sequencer Fees & MEV: BOB earns revenue through sequencer fees from transactions on its L2 network. Additionally, 'good MEV' from DEX rebalancing and liquidations generates exponential revenue growth as activity increases.
- Gateway Swap Fees: BOB Gateway charges fees for native BTC swaps across 11+ chains. Higher swap volume directly increases revenue from these cross-chain Bitcoin interoperability services.
- Hybrid Vault Fees: BOB's BTC yield vaults combine on-chain and off-chain strategies with institutional partners, generating performance fees for the treasury as TVL grows.
- Native BTC Lending & Liquidations: Bitcoin-native lending system where BTC remains secured on Bitcoin while users borrow stablecoins. Powered by BitVM vaults and the liquidation engine, generating revenue from borrowing demand and liquidations.

Build on Bitcoin competitors and assessment
Company assessmentDirect peers
- Babylon Labs: Bitcoin staking protocol and BTCFi infrastructure provider. Babylon and BOB both target native Bitcoin security for DeFi and are co-listed as bitvm/acc working group members, making them direct collaborators and competitors in the Bitcoin staking/locking narrative.
- Rootstock (RSK): Long-standing Bitcoin sidechain providing EVM-compatible smart contracts merged-mined with Bitcoin. Rootstock is a direct peer in Bitcoin DeFi infrastructure with significantly longer operational history but similar product positioning.
- Stacks: Established Bitcoin L2 adding smart contract functionality via Proof-of-Transfer. Stacks competes for the same Bitcoin DeFi developer and user mindshare BOB targets, though with a different consensus and bridging model.
- Citrea: Bitcoin L2 using BitVM for verifiable computation and trust-minimized BTC bridging. Citrea is BOB's closest architectural competitor as both pursue BitVM-based native BTC DeFi on EVM-compatible rollups.
Emerging players
- Alpen Labs: Bitcoin L2 (Strata) building ZK-based trust-minimized BTC bridging. Alpen is an emerging competitor with comparable technical ambition around bringing native BTC into EVM environments, backed by notable crypto VCs.
- Interlay: Creator of interBTC, a trust-minimized wrapped Bitcoin on multiple chains. Interlay competes with BOB Gateway in the cross-chain BTC interoperability space with similar trust-minimized bridging philosophy.
- Threshold Network: Decentralized network operating tBTC, a trust-minimized Bitcoin bridge to Ethereum. Threshold is comparable to BOB in offering wrapped BTC access without centralized custodians and operates in the same cross-chain BTCFi category.
Broad incumbents
- Liquid Network: Bitcoin sidechain operated by Blockstream providing fast BTC settlement and token issuance. Liquid is a broad incumbent in Bitcoin-native financial infrastructure with overlapping institutional and DeFi use cases.
- Optimism: Ethereum L2 whose OP Stack BOB is built on. While not a direct competitor in Bitcoin DeFi, Optimism is the foundational infrastructure provider and a GTM partner (BOB Rise campaign), making it a critical ecosystem relationship.
Others
- LayerZero: Cross-chain messaging protocol that powers BOB Gateway's multichain BTC transfers via OFT standard. LayerZero is an enabling infrastructure partner whose broader interoperability network shapes BOB's competitive positioning.
