About Messiah

Messiah is a Chrome browser extension that protects Web3 assets by scanning websites, transactions, smart contract bytecode and addresses before you sign. It uses advanced AI (OpenAI Codex, Claude Opus 4.6 and proprietary models) and on-chain forensics to identify phishing sites, contract exploits, malicious approvals, and token-level vulnerabilities, then blocks high-risk transactions in real time. Validated by Unphishable (36/36 challenges).
