Stablecoin Freeze Check
Paste any wallet to check whether Tether (USDT) or Circle (USDC) have blacklisted it. We read the issuer's on-chain blacklist directly — a frozen address can't move that stablecoin. Covers 9 chains: Ethereum, BNB Chain, Polygon, Arbitrum, Optimism, Base, Avalanche, Tron, and Solana.
What is a stablecoin freeze?
Tether (USDT) and Circle (USDC) keep a blacklist inside their token contracts. When an address is added to it, that address can no longer send or receive the stablecoin — the balance is effectively frozen in place. Issuers do this in response to OFAC compliance obligations, law-enforcement requests, or reported theft. Because the blacklist lives on-chain, anyone can read it directly — which is exactly what this tool does.
What this tool does
We call the issuer's blacklist function (isBlackListed for Tether, isBlacklisted for Circle) on the native USDT/USDC contract for the chain you pick, and report whether it returns true. On Tron and Solana we check the equivalent freeze mechanism. No transaction is sent and nothing is spent. We only check native Tether/Circle deployments — bridged variants (USDC.e and similar) have no blacklist to read.
What “no freeze” means
It means the issuer has not blacklisted the address on that chain at check time — nothing more. It is not a clean bill of health: the address may be frozen on a different chain, sanctioned without a stablecoin freeze, or freshly frozen a minute later. To screen a wallet properly — sanctions lists, scam clusters, mixers, exposure — run a Quick Check.
