$MEFAI is a wallet security scanner that does deep forensics without requiring wallet connection. Drop any address and it runs a full readonly audit across 18 EVM chains plus Solana.
What it actually checks:
- Complete transaction history scan across all supported networks
- ERC7702 delegation detection (catches drainer contracts)
- Every active ERC20 token allowance including Permit2 and DEX router approvals
- Spam token identification and malicious contract interaction flags
- Generates instant risk score
The killer feature: one-click revoke for risky approvals. Most users have dozens of forgotten allowances sitting there as attack vectors. This tool surfaces them all without needing to connect your wallet first.
Basically a forensic security audit that's normally manual work, now automated. If you've been farming airdrops or testing protocols, you probably have way more active approvals than you think.
