Before you pay USDC
Before you pay USDC: the payee check only, for $0.002. Poison lookalike, USDC blacklist and OFAC. Not the duplicate, catalog price or delivery check. Not a PASS. Not a permission to pay. Arc builders: https://apexfaucet.xyz/arc-builders/. Pay-safe lite: the payee check only, for $0.002. Pass ?payee=<0x>. Optional &chain=arc|base (default arc), &payer=<0x> and &amount= (a USDC decimal). Resource, nonce and window are ignored.
