    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.

How these numbers are made

Each listing is called on a schedule without paying. Listings with usage or a verified owner are checked about every 30 minutes, others about every 6 hours. Uptime is the share of passing checks over 30 days, averaged across this provider's listings. Trust scores follow the published method. The figures on this page can be a few minutes behind the latest checks, and listings hidden after review aren't counted.
