Primary features
The Hemi platform is a modular OP Stack-based Layer 2 blockchain built by Hemi Labs, designed to bridge Bitcoin and Ethereum into a unified supernetwork — inheriting Bitcoin's battle-tested security through a novel Proof-of-Proof consensus mechanism while remaining fully EVM-compatible. At its core, the Hemi platform introduces the Hemi Virtual Machine (hVM), which embeds a full Bitcoin node inside the EVM, giving developers direct, trustless access to Bitcoin's live state.
- Proof-of-Proof Consensus — Hemi block data anchored directly into Bitcoin for inherited PoW finality.
- Hemi Virtual Machine (hVM) — Full Bitcoin node running inside the EVM for native BTC state access.
- Bitcoin Kit (hBK) — Developer toolkit enabling BTC-aware smart contracts, restaking, and lending.
- Tunnels — Bitcoin-secured trustless asset portability between Bitcoin, Ethereum, and Hemi.
In short, the Hemi platform lets developers build EVM-compatible dApps that natively interact with real Bitcoin state — with superfinality inherited directly from Bitcoin's proof-of-work.

User benefits
The Hemi platform allows developers and DeFi users to leverage Bitcoin's unmatched security alongside Ethereum's full smart contract ecosystem — without relying on centralized bridges, wrapped tokens, or trusted intermediaries.
- Smart contracts interact with real, native BTC state rather than synthetic or bridged proxies.
- Superfinality provides settlement security beyond standard Ethereum L2s by anchoring into Bitcoin.
- Trustless Tunnels enable cross-chain asset movement secured by Bitcoin's PoW rather than multisig custodians.
- Full EVM compatibility means existing Ethereum tools, wallets, and auditors work on Hemi without changes.
Overall, Hemi exists to resolve the long-standing divide between Bitcoin and Ethereum — giving the entire developer ecosystem a single, programmable, Bitcoin-secured network to build the next generation of cross-chain applications.
