what's citrea?

Citrea is the first ZK-Rollup for Bitcoin that makes Bitcoin programmable through zero-knowledge technology. The project enables the development of ₿apps (Bitcoin-native applications) that are non-custodial and inherit Bitcoin's security while being EVM-compatible. Citrea uses a BitVM-based trust-minimized bridge called "Clementine" and leverages Bitcoin as a data availability layer. The project completed one year of testnet operations, having posted over 1GB of testnet state directly to Bitcoin Testnet4. Citrea raised $14M in Series A funding led by Founders Fund, with notable investors including Balaji Srinivasan, Jameson Lopp, and Erik Voorhees. The ecosystem features over 30 live ₿apps including DEXs, lending platforms, and other DeFi applications. The project is preparing for mainnet launch with ongoing "Unfreeze ₿apps" campaigns and has conducted multiple hackathons with 120+ builders participating. Citrea combines Bitcoin's security with smart contract expressivity, featuring ZK proofs for transaction security, soft finality for fast confirmations, and cross-chain infrastructure capabilities.
