What Is BOB (Build on Bitcoin) (BOB) and How Does It Work?
BOB (Build on Bitcoin) is a hybrid
Bitcoin Layer-2 blockchain designed to bring full
Ethereum-style smart contract functionality to the
Bitcoin ecosystem. It acts as a bridge between Bitcoin’s unmatched security and Ethereum’s flexible development environment, letting developers build DeFi,
NFTs, and on-chain applications that settle back to Bitcoin. The goal is to make Bitcoin more programmable without compromising its core principles.
BOB works by combining Bitcoin’s base-layer security with an EVM-compatible execution environment. Developers can deploy Solidity smart contracts, while users can bridge
BTC into the network in a trust-minimized way. This hybrid model enables fast finality, low-cost transactions, and native support for Bitcoin assets, making BOB a natural gateway for
Bitcoin-based DeFi applications, liquidity layers, and cross-chain apps.
Under the hood, BOB uses a modular architecture that links Bitcoin, Ethereum, and its own L2 environment. It secures data through Bitcoin anchoring, handles computation through an EVM-compatible L2, and enables seamless interoperability through cross-chain bridges. This design allows BOB to scale Bitcoin’s utility while maintaining a familiar and developer-friendly framework for building advanced applications.
When Did BOB (Build on Bitcoin) Launch?
BOB was founded by Alexei Zamyatin, Co-Founder and CEO, and Dominik Harz, Co-Founder and CTO, along with a broader team including Caroline Mascarin in operations. The project aims to become the “Gateway to Bitcoin DeFi” by marrying Bitcoin’s security with Ethereum-style programmability. According to published data, the native BOB token had its Token Generation Event (TGE) on 20 November 2025 at 12:00 UTC. Prior to that, the network had been in testnet and early mainnet phases, raising funds and building infrastructure through 2024-2025.
Build on Bitcoin (BOB) Roadmap
- Q4 2025: Launch of the mainnet with the native BTC bridge via BitVM, enabling trust-minimised native BTC transfers.
- 2026 H1: Expand the BOB Gateway to enable 1-click multi-chain strategies, hybrid yield vaults, and deeper Bitcoin finality features.
- 2026 H2 and beyond: Roll out hybrid staking, broader ecosystem integrations, and modular rollups for scaling and custom developer deployments.
What Is the BOB Token Utility?
The BOB token is the native asset of the Build on Bitcoin ecosystem and powers the network’s core economic functions. It is used to pay gas fees for executing smart contracts, facilitating transactions, and interacting with dApps on the BOB hybrid Layer-2. BOB also serves as the governance token, allowing holders to vote on protocol upgrades, bridge design choices, and future economic parameters. In addition, BOB is integrated into ecosystem incentives, rewarding developers, liquidity providers, and early adopters who contribute to network growth.

How Does BOB Differ From Other Bitcoin Layer-2 Projects?
BOB differs from other Bitcoin Layer-2 projects by operating as a hybrid chain that combines Bitcoin’s security with full EVM compatibility. While most Bitcoin L2s focus on scaling simple BTC transactions or enabling limited smart contract functionality, BOB offers a complete Ethereum-style development environment anchored to Bitcoin. Developers can deploy Solidity smart contracts, run DeFi protocols, and bridge BTC natively, something not possible on many BTC-only L2s. BOB’s architecture also uses hybrid ZK proofs and BitVM-powered native BTC deposits, enabling trust-minimized interoperability without wrapped assets or custodial bridges.
Another major difference is BOB’s multi-chain flexibility and one-click Bitcoin DeFi experience. Unlike traditional Bitcoin-centric L2s, BOB allows users to move BTC across 11+ major chains, including Ethereum,
Base,
BNB Chain, and Unichain, through a unified gateway. Its ecosystem integrates directly with top-tier DeFi protocols like
Uniswap,
Solv,
LayerZero,
Chainlink, and Anchorage, giving Bitcoin holders access to advanced financial applications with minimal friction. This multi-chain, EVM-first approach makes BOB a more versatile and developer-friendly Bitcoin L2 compared to single-chain or restricted script-based alternatives.
What Blockchain Does BOB Operate on?
BOB operates on a hybrid Layer-2 blockchain that anchors its security to Bitcoin while providing full EVM compatibility through its own execution layer. This means transactions and smart contracts run in an Ethereum-style environment, but the underlying settlement and data commitments rely on Bitcoin, giving BOB the combined benefits of Bitcoin’s security and Ethereum’s programmability. The chain also integrates BitVM-powered native BTC deposits, allowing users to bridge BTC directly into the network without custodial wrappers.
Which Wallets Store BOB Tokens?
The easiest and most secure way to store your BOB tokens is on BingX. When you purchase BOB on the BingX spot market, your tokens are held safely in your BingX account, protected by industry-leading security measures, multi-layer cold storage, and
BingX’s transparent Proof-of-Reserves system. This option is ideal if you want quick access for trading or converting BOB back to USDT at any time.
You can also store BOB in
self-custody wallets that support EVM-compatible tokens, since BOB is represented as an ERC-20 asset on its hybrid chain. Popular options include
MetaMask, Rabby Wallet, and
Base App, each allowing you to add the BOB contract address and access BOB-based dApps. If you choose a self-custody wallet, make sure to store your seed phrase securely and keep enough of the required gas token for smooth transactions.
Is BOB (Build on Bitcoin) (BOB) a Good Investment?
BOB (Build on Bitcoin) is considered a compelling investment because it brings full smart-contract functionality, multi-chain interoperability, and native BTC DeFi to the world’s most secure blockchain. Its hybrid design combines Bitcoin’s settlement strength with Ethereum’s programmability, enabling developers to build advanced dApps while giving BTC holders direct access to staking, yield vaults, and cross-chain liquidity, without wrapped assets or custodial bridges. With backing from leading ecosystem partners, strong community incentives, and a clear four-year token unlock schedule, BOB positions itself as a long-term infrastructure play in the rapidly growing Bitcoin DeFi sector.
