The check before the riskiest moment — signing.

The check before the riskiest moment — signing. Decodes raw unsigned calldata (approve / permit / transfer / setApprovalForAll), shows the exact intent (who gets power over what, and whether it's UNLIMITED), and screens the destination + spender for OFAC sanctions and dangerous owner powers, in one GO/HOLD/STOP verdict + receipt. No simulation needed — pure decode + onchain risk. Catches the unlimited-approval drain vector before it's signed.Overview
