Overview
Bitlayer is a Bitcoin Layer-2 protocol that brings smart contract functionality to Bitcoin without altering its base layer.
• Built on the BitVM paradigm, it enables Ethereum-compatible applications to run with Bitcoin’s security guarantees.
• Acts as a scalable, high-performance execution layer for DeFi, gaming, and other Web3 use cases.
• Think of Bitcoin as a massive vault - Bitlayer is the key that lets developers build on top of it without weakening its security.
• For Ethereum developers, it feels like home - Solidity, EVM compatibility, familiar tools -:but powered by Bitcoin’s unmatched trust layer.
• No need to choose between speed and security - Bitlayer blends both in a developer-friendly sandbox.
• It’s Bitcoin, but with superpowers for the Web3 era.
• Smart Contract Layer on Bitcoin
Uses the Layered Virtual Machine (LVM) to run Solidity, CairoVM, and more.
• Hybrid Optimistic + ZKP Execution
Off-chain computation with rollups that publish proofs back to Bitcoin.
• Native BTC Bridge via BitVM
Trust-minimized, two-way transfers of BTC and wrapped assets.
• Bitcoin-Level Security Without a Fork
State proofs settle directly on Bitcoin’s main chain.
• Ecosystem Reach
Bridges Bitcoin assets into DeFi ecosystems on Base, Starknet, Arbitrum, Sonic, and Plume.
• Leverages BitVM for programmability while preserving Bitcoin consensus rules.
• Supported by 30% of Bitcoin’s mining hashrate, including Antpool, F2Pool, and SpiderPool.
• Functions as a Bitcoin-native rollup-not a sidechain-publishing batched proofs to L1 for verification.
• Backed by leading Bitcoin DeFi projects like Velar, which is building a Bitcoin-native PerpDex on Bitlayer.
• Designed for interoperability and scalability, making BTC a first-class citizen in DeFi.
