Bitcoin ZK Rollup Citrea has restored cross-chain services for ctUSD, USDC, USDT, WBTC and CTR following a comprehensive review. Some Solver-based routes are still being brought back online gradually. The services were previously paused after a security incident involving third-party application Zentra Finance. Citrea said the root cause has been confirmed and related contracts have been suspended, while its protocol and bridge contracts were not affected. The team will separately disclose the incident’s impact on ecosystem projects including ctUSD Earn Vault and depositors.
