Check before you pay

Paste the address, the payment link or the invoice. CompliR grades the wallet in one call and tells you in plain English whether to pay, how much, or not at all. Every answer is signed, mirrored on Arc and kept on a public page you can share.

Try:
Don't pay
Sanctions list, Circle USDC blocklist, Arc protocol blocklist, or funded directly by one of those.
Pay up to N
Something upstream looks off: a sanctioned wallet two hops back, a fresh wallet, a name that changed address. We cap the amount.
Safe to pay
No sanctions, no blocklist, normal history. Signed EIP-712 verdict, mirrored on Arc, re-graded on a cadence.
Privacy
Addresses you check join the public history on their /a/ page. Invoices are read in memory and discarded; your vendor list stays in this browser.
