Hemi is a modular Layer-2 blockchain network designed to unify Bitcoin and Ethereum into a single “supernetwork”. Built using the Cosmos SDK and OP Stack technologies, Hemi runs a Geth-based EVM (the hVM) alongside a unique Proof-of-Proof consensus mechanism that leverages Bitcoin’s hashpower for security. This architecture lets developers deploy Ethereum-standard smart contracts that can seamlessly interact with Bitcoin’s state and assets. By converging the two largest blockchain ecosystems, Hemi enables new possibilities – from Bitcoin-collateralized DeFi and crosschain DEXs to multi-chain DAOs – all on a secure, scalable L2 platform.

__Hemi Labs__
Hemi’s development is led by Hemi Labs, co-founded by early Bitcoin core developer Jeff Garzik and blockchain security expert Max Sanchez. Backed by investors like Binance Labs, Breyer Capital, and Big Brain Holdings, Hemi Labs drives core protocol development and ecosystem growth. The team’s vision is progressive decentralization: with mainnet live as of March 2025, Hemi is moving toward community governance and expanded validator/miner participation.

about-hemi

Launch Solidity-based dApps on an OP Stack Layer-2 that’s enhanced with Bitcoin functionality. Use familiar Ethereum tools (Hardhat, Foundry, MetaMask) to build Bitcoin-aware smart contracts on Hemi written in hVM.

Hemi Virtual Machine embeds a full Bitcoin node inside an EVM environment. Your smart contracts can directly access Bitcoin state and verify Bitcoin transactions, all while using standard Ethereum development frameworks. This unprecedented integration unlocks Bitcoin-native DeFi use cases without trusted intermediaries

Bitcoin-Integrated EVM (hVM)

Infura Ecosystem-Icon

Hemi’s novel PoP consensus anchors the chain’s checkpoints to Bitcoin, inheriting Bitcoin’s security and achieving “better-than-Bitcoin” finality within hours. Every few hours, Hemi transactions reach Bitcoin-level irreversibility – a concept known as superfinality. This gives your dApp the assurance of Bitcoin-grade security alongside fast L2 throughput (block times in seconds).

Proof-of-Proof Security (Superfinality)

Hemi’s RPC endpoints are served by a federation of providers from day one. Developers benefit from geo-distributed nodes, automatic failover, and load balancing across multiple trusted infrastructure providers.

Decentralized RPC via DIN

Hemi redefines what a Layer-2 can be by combining Bitcoin’s proven security with Ethereum’s rich programmability, and delivering seamless interoperability from day one.

High-Performance Infrastructure for Crosschain DeFi

infura+hemi

Sign up for a free Infura account (MetaMask Developer Dashboard) and add Hemi to your project’s networks. You can start interacting with Hemi’s testnet or mainnet instantly using your existing API key

Be Part of the Converged Future

Leverage your go-to Ethereum tools. Connect MetaMask to Hemi (Chain ID 43111), deploy contracts with Hardhat or Foundry, and enjoy Ethereum’s developer experience on a chain that’s also attuned to Bitcoin.

Seamless Integration

Create dApps that span Bitcoin and Ethereum like never before. Whether it’s a BTC lending platform, a crosschain DEX, or an AI application anchored on Bitcoin for trust, Hemi’s infrastructure (28K TPS capacity, sub-15s block times, ~6-conf finality) ensures maximum performance with minimum friction.

Build Without Limits

Hemi is a Bitcoin-secured Layer 2 network that merges Bitcoin’s security with Ethereum’s flexibility. Built on the OP Stack and powered by Proof-of-Proof consensus.
