Wallet Safety Scanner
Scan any wallet for freeze status, sanctions flags, and high-risk interactions. Verify before every P2P trade.
Checks USDT/USDC freeze status, OFAC sanctions, and high-risk interaction history.
Why Check for Blacklisted Addresses?
Tether and Circle have the ability to freeze USDT and USDC held at any address. Once frozen, the tokens cannot be transferred, traded, or redeemed. As of 2026, Tether has frozen over $1.8 billion across 1,000+ addresses, and Circle has blacklisted hundreds of USDC addresses.
This matters most for P2P traders. Receiving USDT from a blacklisted address does not automatically freeze your tokens. However, centralized exchanges may flag your account, request source-of-funds documentation, or temporarily restrict withdrawals. Checking the sender's address before accepting a P2P trade helps you avoid these complications.
How Does Freezing Work?
Both Tether and Circle have admin functions built into their smart contracts. Tether uses addBlackList() and Circle uses blacklist(). Once an address is added, all transfer functions check the blacklist and reject transactions from or to that address.
Freezing typically happens in response to law enforcement requests, hacks, sanctions compliance, or fraud investigations. The process is irreversible without issuer cooperation.
Which Chains Are Supported?
For EVM addresses (0x...), this tool scans Ethereum, BSC, Polygon, and Arbitrum simultaneously — checking USDT and USDC freeze status on all four chains, plus OFAC sanctions via Chainalysis Oracle, plus transaction history across all chains to detect high-risk counterparties.
For Tron addresses (T...), the tool checks TRC20 USDT freeze status and scans recent transaction history for high-risk interactions.
The same address may have different status on different chains — frozen on Ethereum but clean on BSC, for example. That is why we scan all chains at once.
What To Do If Your Wallet Is Flagged
Don't panic. Being flagged does not always mean your funds are frozen. There are different risk levels — a "high-risk interaction" warning is not the same as a full blacklist freeze. Many wallets get flagged simply for receiving funds that passed through a mixer or a sanctioned address several hops back in the transaction chain.
Contact the exchange or platform if your account has been restricted. Most exchanges have a compliance team that can review your case. Provide any documentation they request promptly — delays usually make things worse, not better.
Keep transaction records. Save screenshots of P2P trade conversations, payment receipts, and withdrawal confirmations. If you can prove the legitimate source of your funds (salary, business income, personal savings), compliance teams are far more likely to clear your account quickly.
Consider using a fresh wallet for new transactions if your old address has been flagged. Transfer remaining clean funds to a new wallet through a reputable exchange with KYC — this creates a documented chain of custody that compliance teams can verify.
Report to authorities if you received flagged funds unknowingly. In many jurisdictions, proactively reporting suspicious transactions protects you legally. Contact your local financial authority or cybercrime unit — and keep records of the report for your own protection.
Frequently Asked Questions
Can USDT be blacklisted?
Yes. Tether can freeze USDT on any address, and has done so for law enforcement requests and hack recoveries. Once an address is added to the blacklist via the smart contract, all USDT held at that address becomes non-transferable.
How do I check if a crypto wallet is blacklisted?
Use our free scanner above — just paste any Ethereum or Tron address. Alternatively, you can check directly on Etherscan or TronScan by reading the USDT contract's isBlackListed() function or the USDC contract's isBlacklisted() function for the address in question.
What happens if I receive USDT from a blacklisted wallet?
The USDT itself is not automatically frozen by association. However, centralized exchanges may flag your account for receiving funds from known bad addresses. Some compliance teams will request you to explain the source of funds, and in extreme cases your account could be temporarily restricted pending review.
Can USDC be frozen too?
Yes. Circle, the issuer of USDC, complies with law enforcement and regulatory orders and can freeze any address. Circle has frozen over $100 million in USDC historically, primarily in response to sanctions enforcement and law enforcement requests.
How can I protect myself from receiving blacklisted crypto?
Always verify the sender's address using a tool like this scanner before accepting P2P trades. Use reputable P2P platforms with verified merchants and escrow protection. Avoid unusually good deals that seem too good to be true — they may involve stolen or laundered funds.
Disclaimer: This tool queries on-chain contract data directly. Results reflect the current state of the Tether and Circle blacklists at the time of query. A "clean" result does not guarantee the address is safe — it may be blacklisted after your check. Always do your own due diligence. This is not legal or financial advice.
On-chain contract data queried in real-time from Ethereum, Tron, BSC, Polygon, and Arbitrum. Fees, rates, and availability change frequently — always verify on the official platform before transacting.
