# Bitlayer

Bitcoin L2 with focus on **BTC staking** for yield, plus EVM
smart contracts.

## Architecture

- **ZK rollup** with state commitments to Bitcoin.
- **EVM compatibility** for Solidity contracts.
- **BTC staking** — bridged BTC earns yield via Bitlayer's protocols.
- **Federation peg** (planned BitVM upgrade).

## Position

Among the "BTCFi" Bitcoin L2s competing on yield products. TVL
moderate (early 2026).

## Use cases

- **BTC staking** for yield.
- **DeFi protocols** (lending, AMMs).
- **Bridge integrations** to Ethereum L2s.

## Limitations

- **Federation trust** until BitVM bridge.
- **Yield sources** sometimes unclear / require careful audit.
