ChainLight is an award-winning blockchain security firm established in 2016, operating as the Web3 security division of Theori. Powered by some of the world's leading white hat hackers, ChainLight provides tailored security solutions to fortify smart contracts and help blockchain projects thrive safely. The team has an exceptional competitive record, winning major cybersecurity competitions including DEF CON, CODEGATE, HITCON, SECCON, Google CTF, Paradigm CTF, and many others every year from 2016 to 2023.

Core Products/Services

ChainLight's solutions portfolio is focused on three primary offerings:

Security Audit is the flagship service, delivering comprehensive smart contract and blockchain security reviews. With a proven track record of zero client compromises, ChainLight's audit process covers five phases: request and scoping, quote and audit strategy, real-time security examination and vulnerability reporting, security consultation and code review, and final audit report with certification. The team has published audit reports for major blockchain protocols including Blur/Blend NFT Marketplace, Kroma (L2/Blockchain Node), Klaytn Governance Contracts, and has identified critical bugs in ZKSync Era (zk-EVM soundness bug) and TON Network (node-killing vulnerability).

DART (Digital Asset Risk Tracker) is ChainLight's Web3 risk management product, described as a vigilant sentinel that reveals concealed threats often missed by standard risk assessments and security audits. DART goes beyond conventional risk management by uncovering hidden vulnerabilities such as unlimited token minting capabilities, circulating supply mismatches, centralized minting authority, and upgradeability risks.

Relic Protocol is the world's first trustless oracle for Ethereum's historical data. Utilizing zk-SNARKs and optimized on-chain state verification, Relic Protocol enables decentralized applications to access historical blockchain data securely without relying on third-party authorities, while minimizing gas usage.
