. @retrodao_kr just dropped something big.
Imagine this: a full Bitcoin node running inside an EVM. that’s Hemi VM by @hemi_xyz. No oracle. No bridge. Just native Bitcoin-Ethereum interoperability.
✅ BTC tx verification on-chain
✅ WBTC mint/burn via SPV
✅ Solidity-based Bitcoin apps

explaining how the @hemi_xyz Virtual Machine (hVM) integrates a full Bitcoin node within an EVM, enabling seamless cross-chain applications
The Hemi Virtual Machine (hVM) is an innovative blockchain execution environment that integrates a full Bitcoin node within an Ethereum Virtual Machine (EVM)-compatible framework, enabling seamless cross-chain applications between Bitcoin and Ethereum-based ecosystems.
Here’s how it works
1. Core Architecture of hVM
The hVM extends the EVM by embedding a Bitcoin full node directly into its runtime, allowing smart contracts to interact natively with Bitcoin’s blockchain. This integration enables:
- Bitcoin state verification (SPV-like proofs or full validation).
Direct Bitcoin transaction execution (sending, receiving, and verifying BTC transactions).
Seamless interoperability between Bitcoin and EVM-based chains (e.g., Ethereum, Polygon, Arbitrum).
2. Key Components
Bitcoin Node Integration
- A light client or full node runs inside the hVM, enabling smart contracts to verify Bitcoin transactions without relying on third-party oracles.
Uses Bitcoin’s UTXO model for trustless verification within EVM contracts.
EVM Compatibility
- Supports Solidity/Vyper smart contracts, allowing developers to write Bitcoin-aware dApps.
Extends EVM opcodes to include Bitcoin-specific operations (e.g., verifying BTC transactions, checking UTXOs).
Cross-Chain Messaging
- Uses atomic swaps, wrapped BTC (WBTC), or bridges to move value between Bitcoin and EVM chains.
Enables Bitcoin-backed DeFi (e.g., BTC lending, staking, or liquidity provisioning).
3. How Cross-Chain Applications Work
BTC → EVM Transactions
- A smart contract in hVM can lock BTC in a Bitcoin transaction and mint a corresponding wrapped asset (e.g., WBTC) on the EVM side.
Uses SPV proofs or Bitcoin light client verification to ensure trustlessness.
EVM → BTC Transactions
- An EVM smart contract can burn wrapped BTC and release native BTC by submitting a Bitcoin transaction via the embedded node.
Bitcoin-Aware Smart Contracts:
The Hemi Virtual Machine (hVM) bridges Bitcoin and EVM ecosystems by embedding a full Bitcoin node inside an EVM, enabling trustless cross-chain applications. This unlocks Bitcoin’s liquidity for DeFi, NFTs, and more while maintaining security and decentralization.
