Sentinel Token Safety

Token safety pre-flight — one verdict before your agent buys, swaps or approves any ERC-20 on Base (GET ?contract=0x… or POST body {contract}). Call it right before the trade and branch on `verdict`: ALLOW / WARN / BLOCK, with `action`: PROCEED / REVIEW / ABORT and a one-line `reason`. Aggregates honeypot and scam-token detection, buy tax and sell tax, transfer restrictions, hidden mint and owner privileges, and EIP-1967 proxy upgrade risk into a single decision. `checks` carries the raw fields for audit. $0.10 USDC
