What is BOB (BOB)?

Quick Facts

  • Full name: BOB — Build on Bitcoin
  • Type: Hybrid EVM-compatible Layer-2 blockchain
  • Underlying stack: OP Stack (optimistic rollup)
  • Token utility: Staking, governance, protocol access
  • Governance: BOB DAO with on-chain voting
  • Backers: Coinbase Ventures, Castle Island VC, Ledger
  • Token launch: November 2025 (TGE)

Introduction

BOB — short for Build on Bitcoin — is a hybrid Layer-2 network designed to unite Bitcoin's security with Ethereum's smart contract capabilities. The project's mission is straightforward: make Bitcoin productive inside decentralized finance, transforming it from a passive store of value into active collateral for swapping, lending, and earning yield.

History & Background

BOB was created by the team behind Interlay, a decentralized Bitcoin infrastructure provider. Co-founders Alexei Zamyatin and Dominik Harz announced the project in 2023, launching an MVP featuring an integrated Bitcoin light client and trustless bridge. The mainnet went live ahead of the 2024 Bitcoin halving, and by the time of the Token Generation Event in late 2025, the network had accumulated over $300 million in total value locked and more than one million wallets. The project raised $23.7 million across seed, strategic, and public rounds from backers including Coinbase Ventures, Castle Island VC, and Ledger.

How BOB Works

BOB is built on the OP Stack, making it an EVM-compatible optimistic rollup. This means developers can deploy Solidity smart contracts using familiar Ethereum tooling, while the network ultimately anchors security to Bitcoin.

A key innovation is the BOB Gateway, which uses 'Bitcoin intents' to route cross-chain swaps — letting users move native BTC to any supported chain with a single action. BitVM technology, co-authored by a BOB founder, underpins a trust-minimized bridge between Bitcoin and EVM networks. Chainlink CCIP is used as the sole supported path for BOB token portability across chains.

Tokenomics

The BOB token serves three core functions: security (staking to Hybrid Nodes and bridge operators), governance (voting on network upgrades and treasury), and protocol utility (priority access and discounts for holders). Approximately 44.76% of the token supply is reserved for the ecosystem and community, with the remainder distributed among investors, team, and foundation — all subject to vesting schedules. The BOB Foundation and BOB DAO jointly steward the community treasury.

Ecosystem & Use Cases

BOB supports a wide range of BTCfi applications: cross-chain BTC swaps, 1-click BTC yield strategies, collateral-backed stablecoin borrowing, and low-fee payments. Its BOB Gateway supports over eleven major chains including Ethereum, Base, and BNB Chain, enabling seamless BTC liquidity flow into multi-chain DeFi.

Team, Governance & Community

The project was founded by Alexei Zamyatin and Dominik Harz from Interlay. Governance is handled by the BOB DAO, which votes on core protocol upgrades including the underlying network, BitVM, and Gateway components. Treasury allocations are also subject to DAO votes, ensuring community oversight of long-term resources.

Advantages

  • Hybrid architecture merges Bitcoin security with Ethereum's DeFi tooling
  • EVM compatibility lets Ethereum developers deploy on Bitcoin rails without relearning tooling
  • BOB Gateway enables 1-click BTC access across 11+ chains
  • Trust-minimized bridge using BitVM reduces reliance on custodians
  • Community-first tokenomics with the largest share directed to ecosystem growth

Risks & Challenges

  • Bridge risk: Cross-chain bridging remains a common attack surface in DeFi
  • Optimistic rollup assumptions: Fraud-proof windows introduce withdrawal delays
  • Competitive landscape: Numerous Bitcoin L2s are competing for the same BTCfi market
  • DAO governance complexity: Managing a large community treasury requires robust and transparent processes
  • Adoption dependency: Long-term value relies on continued developer and user growth

Long-Term Vision

BOB frames itself as building the Bank of Bitcoin — a single platform for swapping, saving, earning, and borrowing, all secured by Bitcoin. The roadmap includes introducing Bitcoin finality through Hybrid Nodes, expanding BitVM bridge capabilities, and deepening integration across the multi-chain DeFi ecosystem. The broader goal is to unlock Bitcoin's latent value for the hundreds of millions of users who hold it, bringing them access to the full range of decentralized financial services.

Frequently Asked Questions

BOB stands for 'Build on Bitcoin.' It is a hybrid Layer-2 blockchain network designed to bring Bitcoin into the world of EVM-compatible decentralized finance.

BOB is built on the OP Stack, making it an EVM-compatible optimistic rollup. It uses Bitcoin for security and Ethereum's Virtual Machine for smart contract execution.

The BOB token is used for staking to Hybrid Nodes, participating in on-chain governance via the BOB DAO, and accessing protocol features like priority access and discounts.

BOB was created by Alexei Zamyatin and Dominik Harz, the co-founders of Interlay, a decentralized Bitcoin infrastructure company. The project has raised $23.7 million from investors including Coinbase Ventures and Ledger.

The BOB Gateway is a cross-chain toolkit that uses 'Bitcoin intents' to facilitate seamless BTC swaps across over eleven major chains, including Ethereum, Base, and BNB Chain, with a single click.

BOB uses a decentralized autonomous organization called the BOB DAO for on-chain governance. Token holders vote on protocol upgrades, treasury allocations, and other key decisions.

BitVM is a technology for creating trust-minimized bridges between Bitcoin and other networks. A BOB co-founder helped author the BitVM protocol, and BOB uses it to underpin its Bitcoin bridge infrastructure.

The BOB token is natively minted on the BOB network and is available on BNB Smart Chain and other EVM-compatible chains. Chainlink CCIP is the official bridge used to move BOB tokens across supported chains.
