Yes. A self-custody wallet protects your keys, not the token: USDT and USDC are smart contracts whose issuers, Tether and Circle, can blacklist an address so the contract refuses to move that balance, whichever wallet holds the keys. No wallet can override an issuer freeze, including non-custodial WATS Wallet, which holds none of your keys and cannot freeze anything either. As of October 2026, the US GENIUS Act (signed 18 July 2025, effective no later than 18 January 2027) requires permitted stablecoin issuers to be technically able to comply with lawful freeze orders.
What does "frozen" mean when you hold your own keys?
A frozen stablecoin is a balance that the issuer's token contract refuses to move, even though you still control the keys. Your wallet only signs transactions; the USDT or USDC balance is a record inside the issuer's contract on each chain (see what a stablecoin is).
The contract checks a blacklist, or the frozen state of a token account, before a transfer, so the wallet still shows the balance but sending fails. Importing the same seed phrase into another wallet derives the same address, so the funds stay frozen.
Only that token is affected. Native coins such as ETH, BNB, SOL and GRAM (formerly Toncoin) have no issuer and no issuer-controlled freeze, and other tokens at the same address keep moving unless their own contracts restrict them. A custodial exchange can instead freeze a whole account (see custodial vs non-custodial wallets).
How do USDT and USDC blacklists work on each chain?
Each chain implements the freeze differently, which is why ERC-20, SPL and jetton tokens behave differently. Always check the specific contract.
| Token and chain | Mechanism | Can a frozen address receive? | Can the issuer destroy the funds? |
|---|---|---|---|
| USDT on Ethereum and Tron | Tether calls addBlackList; removeBlackList lifts it | Yes, inbound transfers still land (per BlockSec) | Yes, via destroyBlackFunds |
| USDC on EVM chains | Circle's blacklister role calls blacklist and unBlacklist | No, it can neither send nor receive | No such function in the FiatToken source |
| USDC and USDT on Solana | The mint's freeze authority freezes a token account | No, until the account is thawed | A freeze alone does not burn funds |
| USDT on TON (jetton) | Admin governance mechanism in the contract | Check the contract | Check the contract |
On Solana, a mint whose optional freeze authority is revoked can never freeze accounts; on-chain data for the USDC and USDT mints in October 2026 shows a freeze authority set on both. On TON, the official documentation says the USDT contract has a governance mechanism that lets an admin perform actions on other jetton wallets.
Who decides a freeze, and why does it happen?
The issuer carries out the freeze, often after a government request or a sanctions listing. Tether's terms (updated 26 February 2026) allow freezing and blacklisting when directed by a government, on suspected violations or where the law requires it. Circle's USDC terms (updated 12 December 2025) let it block addresses that, in its sole discretion, may be associated with illegal activity. Per BlockSec, Tether acts on verified agency requests, not always court orders, and freezes OFAC-sanctioned addresses proactively.
- 8 August 2022: after the OFAC designation of Tornado Cash, USDC addresses tied to it were blacklisted, freezing at least 75,000 USDC (The Block).
- 23 March 2026: Circle froze 16 addresses under a sealed US civil court order, including the DFINITY ckETH minter contract, which affected users with no link to the case (AMLBot, 26 March 2026).
- 23 April 2026: Tether froze about $344M USDT on two Tron addresses in coordination with US authorities (Cryptonomist).
Innocent holders can be caught when funds trace to hacks, scams, sanctioned entities or a shared service address.
How much USDT and USDC has been frozen?
Totals depend on the source, method and date, so each figure carries both. BlockSec (30 January 2026) counted $1.26B of USDT frozen across 4,163 addresses on Ethereum and Tron in calendar 2025. Of the frozen value, 55.6% ($698.42M) was destroyed through destroyBlackFunds, and only 3.6% of the addresses (150) were removed from the blacklist within 2025.
Tether itself said, as reported on 23 April 2026, that its global frozen total exceeds $4.4B, with more than $2.1B of it in cooperation with US authorities. The two figures measure different things (one year on two chains versus a global running total) and should not be added together.
What does the GENIUS Act require of stablecoin issuers?
The GENIUS Act requires permitted US payment stablecoin issuers to be technically able to comply with lawful orders to seize, freeze, burn or block transfers. It was signed on 18 July 2025 as Public Law 119-27.
- Sec. 4(a)(6)(B): a permitted issuer may issue payment stablecoins only if it can comply, and will comply, with any lawful order.
- Sec. 2(16): a lawful order is a final, valid order from a court or authorized federal agency to seize, freeze, burn or block transfers of the issuer's stablecoins, identifying them with reasonable particularity and subject to judicial or administrative review.
- Sec. 3(b): once the service-provider restriction applies (three years after enactment, 18 July 2028, under Sec. 3(b)(1)), a digital asset service provider may not offer a foreign issuer's payment stablecoin in the US unless that issuer has the technological capability to comply, and will comply, with lawful orders and any reciprocal arrangement under Sec. 18. Sec. 3(h)(1) exempts transactions made through a software or hardware wallet that facilitates an individual's own custody.
- Sec. 20: the Act takes effect on the earlier of 18 January 2027 or 120 days after final implementing regulations, so no later than 18 January 2027; some provisions, such as the Sec. 3(b)(1) service-provider restriction, apply later.
Freezability is becoming a legal requirement for permitted US payment stablecoin issuers and, through the service-provider rule, a condition for foreign issuers' coins offered in the US, not just a contract feature. This is not legal advice and takes no view on how regulators or courts will apply the text.
How can you check whether an address is blacklisted?
You check by reading the issuer's contract on a block explorer, which is the primary source (see how to read a block explorer). Confirm the official contract address from the issuer first.
- USDT on Ethereum and Tron: on the official contract, open Read Contract and call getBlackListStatus (or isBlackListed) with the address. True means frozen.
- USDC on EVM chains: the contract is a proxy, so use Read as Proxy and call isBlacklisted.
- Solana: look up the token account on an explorer; its state reads Frozen if the freeze authority froze it.
- TON: inspect the jetton wallet in an explorer such as Tonviewer.
Third-party checkers are a convenience only. If the balance shows but every send fails or reverts in simulation, rule out the wrong network and missing fee funds first.
How do you avoid receiving tainted stablecoins?
You avoid it by screening counterparties before you accept funds.
- Before a large payment or P2P trade from a stranger, check the sender address on an explorer for links to hacks, scams or sanctioned services.
- Check an address before sending USDT to it: per BlockSec, a blacklisted address can still receive USDT, and those funds are then stuck too.
- Keep invoices, chat logs and transaction hashes showing where funds came from.
If your address is frozen, only the issuer can lift it. Contact Tether or Circle through official support channels and get qualified legal help. Treat anyone selling "unfreeze" or "USDT recovery" services as a likely scam.
Can WATS Wallet freeze your stablecoins?
No. WATS Wallet, made by Alltoscan LLC, is fully non-custodial: you create and hold your own keys and seed phrase in the Chrome extension and the iOS and Android app. WATS never holds a key, with no co-signer, no MPC share and no recovery back door, so it cannot freeze, move or seize your funds.
Equally, WATS Wallet cannot override or lift an issuer-level freeze on USDT, USDC or any token whose contract has one. It supports EVM networks, Solana and TON, so the per-chain rules above apply there. On EVM networks WATS charges fees in ATS from one balance on BSC through an ERC-4337 paymaster (see the ATS fee); that changes how you pay network fees, not who controls a token contract. The optional WATS NFC Metal Card is tap-to-authenticate only: it holds no keys and has no effect on freezes. For holding USDT and USDC across chains, see wallets for stablecoin payments.
Frequently asked questions
If my USDT is frozen, can I move it by importing my seed phrase into a different wallet?
No. The freeze is recorded against your address in the USDT token contract on that chain. Importing the same seed phrase into another wallet derives the same address, so the contract still refuses the transfer. Native coins and other tokens at that address can still be moved unless their own contracts restrict them, and only the issuer can lift the freeze.
How do I get frozen USDT or USDC unfrozen?
Only the issuer can lift a freeze: Tether calls removeBlackList and Circle calls unBlacklist. Contact the issuer through its official support or legal channel with evidence of where the funds came from, and consider a qualified lawyer. Set expectations: BlockSec reported that only 3.6% of the addresses Tether blacklisted in 2025 were removed from the blacklist within that year. Be wary of anyone who contacts you offering an unfreeze or recovery service, which is a common scam. This is not legal advice.
Can my ETH, SOL or other tokens be frozen too?
Native coins such as ETH, BNB, SOL and GRAM on TON have no issuer and no issuer-controlled freeze function in a token contract. A freeze applies only to the specific token whose contract has a blacklist or freeze authority, so other tokens at the same address are unaffected unless their own contracts include such controls. Some issuer-run tokens do. On Solana check whether the mint has a freeze authority, and on EVM chains read the contract.
