Deploy your first Bitcoin-native
contract in four steps

Deploy your first Bitcoin-native contract in four steps

Write, deploy, and verify Solidity contracts directly on Bitcoin. No wrappers, bridges, or new tooling.

1

Connect your wallet

Use MetaMask or any EVM-compatible wallet.

2

Fund your deployment

Claim test BTC and ETH from the faucet.

3

Deploy your contract

Use Remix or Foundry, select the Hemi network, and deploy with hVM.

4

Query Bitcoin state

Access headers, balances, and UTXOs through the hBK module.

Bitcoin security.
Ethereum programmability.
One execution layer.

Hemi runs Solidity contracts while exposing native Bitcoin state inside the EVM. Its dual-layer architecture pairs hVM for contract execution with hBK for trustless Bitcoin state access.

hVM (Hemi Virtual Machine)

The hVM wraps a Bitcoin node in an EVM-compatible runtime, combining Bitcoin’s security with Ethereum-grade programmability in a unified execution layer.

hVM enables

Low-fee Bitcoin DeFi

Non-custodial Bitcoin services

Multi-chain DAOs

Bitcoin-secured AI applications

Cross-chain exchanges

Bitcoin-backed financial instruments

What is Hemi?

Hemi is a dual-layer protocol that makes Bitcoin programmable. It combines Bitcoin’s Proof-of-Work security with Ethereum-level smart contract execution through the Hemi Virtual Machine (hVM) and Hemi Bitcoin Kit (hBK).

How does Hemi differ from other Bitcoin Layer-2s?

Hemi anchors every transaction to Bitcoin via Proof-of-Proof (PoP), inheriting Bitcoin’s full security. Other L2s rely on bridges, wrapping, or hybrid validation. Hemi keeps assets and logic verifiable on-chain.

How is Hemi secured?

All Hemi blocks are anchored to Bitcoin through Proof-of-Proof. This means Bitcoin miners indirectly secure the network. Every transaction can be traced back to Bitcoin’s Proof-of-Work chain.
