Hemi Network
Hybrid L2 by Hemi Labs combining Bitcoin and Ethereum. Featured "superfinality": uses Bitcoin's PoW to provide an additional finality layer beyond Ethereum's.
Architecture
- EVM execution with Solidity.
- Anchored to Ethereum for DA.
- PoW finality from Bitcoin: state checkpoints periodically committed to Bitcoin chain.
- Bridge: Multi-chain bridge to BTC, ETH, and other L2s.
Superfinality
After Ethereum-style finality, Hemi additionally requires Bitcoin checkpoint:
- Provides "irreversibility" akin to Bitcoin's beyond Ethereum's.
- Trade-off: longer effective finality time.
Position
Significant TVL (~$1.2B early 2026), 90+ protocols deployed. Among the more active "hybrid Bitcoin L2" projects.
Use cases
- Cross-chain DeFi.
- Apps requiring strongest finality from both chains.
- NFT bridges Bitcoin Ordinals ↔ Ethereum NFTs.
Limitations
- Complex security model.
- Dual chain dependency.
