Citrea is building Bitcoin’s first ZK rollup, bringing programmable apps secured by Bitcoin consensus 🍊🍋 Both the rollup and the BitVM-based Clementine bridge have now completed public audits, putting @citrea_xyz in the final stage before mainnet. here’s why this matters ⬇️
Citrea Fully Completes Its Audit Phase! All audits for our rollup (Citrea) and BitVM-based bridge (Clementine) are complete, marking a major step toward the mainnet launch of Bitcoin’s first ZK rollup 🧵
Bitcoin was never built for smart contract execution. That pushed liquidity into wrapped assets, custodial bridges and external chains. The goal is to scale Bitcoin without weakening its security model Citrea extends Bitcoin using ZK proofs, keeping Bitcoin as the root of trust

Citrea executes app logic off-chain and posts validity proofs to Bitcoin. This preserves Bitcoin’s settlement guarantees while enabling Bapps like DEXs, lending markets, games and more The rollup and prover architecture are customized for Bitcoin’s UTXO model and data constraints Programmability, without leaving Bitcoin

To verify robustness under real adversaries, @citrea_xyz ran two public audit competitions with @cantinaxyz Participation was broad: • 510 researchers on the rollup • 535 researchers on the Clementine (bridge) results: • Rollup: 84 findings (2 high, 10 medium) → all significant issues resolved • Clementine: 117 findings (2 high, 3 medium) → all significant issues resolved Fixes covered UTXO handling, sequencer stability, state machine edge cases, fee logic and proof flow reliability

Next milestone: Risc0 → BitVM Trusted Setup Ceremony, which will establish the cryptographic parameters securing the bridge. This will be the first trusted setup for ZK proofs in a BitVM-based bridge After that comes mainnet This unlocks: • Bitcoin’s first ZK rollup • A trust-minimized BTC-native bridge • The first real wave of Bapps and onchain Bitcoin liquidity Programmable Bitcoin is about to become real
