Hemi

Hemi was built on a simple but powerful thesis: Bitcoin has unmatched security, but no programmability; Ethereum has powerful smart contracts, but lacks Bitcoin-native trust. Most attempts to bridge the two have relied on custodial or synthetic systems. Hemi offers something different—a single execution environment where both chains are foundational, not secondary.

The result is an environment where a dApp can settle value in BTC, execute logic in Solidity, and benefit from dual-chain security without custodians or trust-minimized bridges.

Architectural Overview

Hemi’s system introduces a modular stack built to support high-throughput applications with ultra-secure finality:

1. hVM (Hemi Virtual Machine)

An execution layer that wraps a full Bitcoin node within an EVM context, allowing smart contracts to directly query Bitcoin UTXO state and respond to BTC-native events.

2. Proof-of-Proof (PoP) Consensus

Hemi checkpoints its block headers into the Bitcoin blockchain using an anchoring mechanism, effectively “finalizing” its own block history using Bitcoin’s proof-of-work. This gives the network a unique level of economic security—anchored by BTC itself.

3. Ethereum Integration

Hemi also publishes state roots and fault-proofs to Ethereum, ensuring smart contract integrity and enabling cross-rollup composability within the EVM ecosystem.

4. Bitcoin-Secured Sequencer

Sequencer nodes collect and verify Bitcoin block headers and use them to organize Hemi’s internal execution timeline—bridging BTC's consensus with Hemi’s smart contract layer.

Capabilities & Use Cases

Hemi is not built for general-purpose dApps or meme coins. It is targeted at:

• Cross-chain DeFi: Apps that need native BTC access while leveraging the full scope of Ethereum’s DeFi ecosystem.

• Bitcoin-native smart contracts: Contracts that react to BTC movements or UTXO activity without relying on oracles or custodians.

• hTokens and Tunnels: Asset bridges that allow BTC, ETH, and other tokens to move across the Hemi network trustlessly.

• Sovereign DAOs: Governance systems that can coordinate activity across Bitcoin and Ethereum simultaneously.

Ecosystem and Adoption

Since its mainnet launch, Hemi has attracted rapid traction:

• Over $440 million in total value locked within days of launch

• A DeFi stack that includes DEXs, AMMs, lending protocols, vault strategies, and decentralized stablecoins

• Integration from major Web3 infrastructure partners including oracle networks, bridge providers, and restaking frameworks

• Immediate interest from teams building Bitcoin-backed stablecoins, hybrid DAOs, and programmable BTC derivatives

Hemi offers what no other Layer 2 can: Bitcoin-native trust with Ethereum-native logic, tightly bound into a coherent network. It does not rely on synthetic tokens, off-chain oracles, or cross-chain hacks. Instead, it embeds two consensus systems into one unified model.For developers building the next generation of cross-chain DeFi, asset-backed stablecoins, or programmable Bitcoin utilities, Hemi delivers the foundational infrastructure to do so without compromise.
