Service Overview

ChainLight's flagship security audit service is backed by a proven track record of zero client compromises. Every audit is conducted by security researchers who operate at the highest levels of offensive security, bringing real-world attacker perspective to blockchain defense. The team has uncovered critical bugs in ZKSync Era (zk-EVM soundness bug) and TON Network (node-killing vulnerability), and published audit reports for major protocols including Blur/Blend, Kroma, Klaytn, and PancakeSwap.
