WalletTriage — real-time wallet risk check: dangerous ERC20 approvals cross-referenced with a live exploit threat feed. Returns risk_score (0-100), risk_level and actionable findings.

Explain and preflight an unsigned Base transaction, EIP-712 typed data, or an EIP-3009 x402 payment authorization before you sign it.

Returns unknown rather than guessing when a selector is ambiguous. Not a guarantee that a transaction is safe or profitable.
