Yes, USDT can be frozen. Tether can blacklist any address that holds USDT, and once it does, the tokens at that address can't be sent until Tether lifts the block. Circle can do the same with USDC. Both issuers used that power after the late-October 2026 Binance hack: Tether said it froze more than $1.5 billion in USDT and Circle more than $800 million in USDC tied to the theft, per CNBC. Bitcoin and ether stolen in the same attack could not be frozen the same way, because they "have no issuer that can directly freeze the assets," per CNBC.

For most holders a freeze is a remote risk: it targets specific addresses, not everyone who holds the coin. This guide explains how stablecoin freezes work, how often they happen, and what they mean if you hold USDT or USDC to spend.

This article is general information, not legal or financial advice.

Can USDT be frozen? The short answer

USDT and USDC are tokens issued by companies. On Ethereum and Tron, Tether's USDT contract keeps a blacklist of addresses that the issuer controls. Circle runs its own blocklist for USDC. When an address goes on the list, the tokens stay where they are, but the holder can't move them.

Three things decide whether a coin can be frozen:

  1. Is there an issuer? USDT and USDC have one. Bitcoin, ether and SOL don't.
  2. Did the issuer build a freeze function into the token? Tether and Circle did.
  3. Is your address the one being blocked? A freeze applies address by address. It is not a switch that stops every USDT in the world.

How a stablecoin freeze works, chain by chain

USDT on Ethereum and Tron

The USDT contract has an owner-only function called addBlackList. Calling it flags an address, and a paired removeBlackList function undoes the flag, per BlockSec's analysis of the contract. A third function, destroyBlackFunds, burns the balance of an address that is already blacklisted. BlockSec notes that the Ethereum and Tron blacklists are separate, so a freeze on one chain doesn't freeze the same address on the other.

Tokens on Solana

Solana tokens use a different mechanism: a mint can have an optional freeze authority. That authority can freeze any token account for that mint. A frozen account keeps its balance but can't send, receive or burn tokens until the authority thaws it, per the Solana docs. The docs also note that native wrapped-SOL token accounts can't be frozen.

Freeze, burn, reissue

A freeze doesn't have to be permanent. Tether and Circle "can freeze, burn and reissue, which allows frozen USDT and USDC to be returned to a victim," per CNBC. The route CNBC describes is law enforcement obtaining a court order or seizure warrant, then working with the issuer to release or reissue the tokens to their rightful owners.

When Tether and Circle say they can freeze

Both issuers put the power in their terms, and both leave themselves wide discretion.

Tether. Tether's terms of service let it freeze tokens held by a user when required by law or when it "determines it is prudent to do so." Among its remedies for prohibited use, the terms list blacklisting any address that holds Tether tokens and freezing or confiscating tokens.

Circle. Circle's USDC terms say it can block addresses that it "determines, in its sole discretion, may be associated with illegal activity," and freeze the USDC at them, "temporarily or permanently." The holder "may forfeit any rights associated with your USDC, including the ability to redeem USDC for USD." The terms also say Circle may be required to freeze USDC if "it receives a legal order from a valid government authority."

Does the GENIUS Act require stablecoins to be freezable?

For US-regulated issuers, yes. The GENIUS Act, the US federal law for payment stablecoins, says a permitted issuer "may issue payment stablecoins only if the issuer has the technological capability to comply, and will comply, with the terms of any lawful order," per the statute.

The law defines a "lawful order" as a final, valid order from a court or an authorized federal agency. It must require the issuer to "seize, freeze, burn, or prevent the transfer of payment stablecoins." It must also identify the coins or accounts "with reasonable particularity" and be "subject to judicial or administrative review or appeal."

That definition helps holders in one way: an order under the Act has to name specific coins or accounts and can be challenged. It does not remove the issuer's own contractual right to freeze. For the rest of the law, see our GENIUS Act explainer.

How often are stablecoins frozen?

Freezes add up to billions of dollars, spread across thousands of addresses.

FigureValueSource
USDT addresses blacklisted on Ethereum and Tron (as of July 26, 2026)9,597BlockSec

USDT frozen after the Binance hackMore than $1.5 billionCNBC
USDC frozen after the Binance hackMore than $800 millionCNBC

Two cautions on reading these numbers. Tether's law-enforcement total and BlockSec's on-chain count measure different things: the on-chain count also covers sanctions listings and Tether's own monitoring, per BlockSec. And the Circle figure covers a different period from the Tether one, so the two counts aren't a like-for-like comparison.

What the Binance hack showed about freezes

The October 2026 attack is a clear test of what freezing can and can't do.

  • The size. Binance was hacked "with an estimated impact of $6.3 billion," per CNBC. CNBC called it the largest crypto theft on record.
  • What got stopped. "Around $3 billion in cryptocurrency assets have been frozen so far, according to a Binance security update," per CNBC. Separately, Tether and Circle reported more than $2.3 billion in stablecoin freezes between them.
  • What didn't. Recovering bitcoin and ether "is more challenging because they have no issuer that can directly freeze the assets," per the same report.

The lesson works both ways. The freeze function that stopped stolen USDT and USDC from leaving is the same one that could, in principle, stop an ordinary holder's coins. Whether that is reassuring depends on whether you are the victim or the address being flagged.

What can and can't be frozen

What you holdCan an issuer freeze it?Why
USDT on Ethereum or TronYesOwner-only blacklist in the contract, per BlockSec
USDCYesCircle's blocklist, per its terms
Any token on Solana whose mint has a freeze authorityYesThe freeze authority can freeze token accounts, per the Solana docs
Bitcoin, etherNo issuer canNo issuer exists, per CNBC
Coins held on an exchangeThe exchange can restrict your account under its own termsA separate risk from a token freeze
A prepaid card balanceNot a token, so no token freeze appliesThe card program has its own terms and compliance duties

"Can't be frozen by an issuer" isn't the same as "safe." Bitcoin and ether carry price swings that stablecoins are designed to avoid, and any coin on an exchange is subject to that exchange's account rules.

What a freeze means if you hold stablecoins to spend

If you keep USDT or USDC in a wallet and top up a card from time to time, here is where freeze risk actually sits.

Where your coins come from matters

A freeze targets addresses linked to theft, sanctions or other illegal activity. The practical way to stay clear of it is to get stablecoins from a regulated exchange or a known counterparty rather than an unknown peer-to-peer seller, and to be wary of payments from strangers. Tether's terms let it act when it "determines it is prudent to do so," per its terms. Our security basics for card users cover the scams that most often reach spenders.

You can check an address

Blacklist status is public. You can look up an address on Etherscan or Tronscan, or paste it into BlockSec's free USDT freeze checker, per BlockSec. It is worth doing before you accept a large USDT payment from someone you don't know.

A card balance is a different thing from a token

A prepaid crypto card that converts your deposit into a fiat balance holds dollars for spending, not USDT. SolCard works this way: it is a prepaid Visa / Mastercard card, and your crypto converts to fiat when you top up. The tokens-in-a-wallet risk, from freezes as well as from a stablecoin depeg, mostly sits with the coins before you deposit them.

What that does not mean:

  • It isn't a way around a freeze or the law. Card programs have their own compliance obligations, and a card balance is held by the card program and its issuing partner.
  • It doesn't protect coins you haven't deposited. Stablecoins in your wallet are exposed for as long as they sit there.
  • It costs something. SolCard's Virtual card charges a 5% top-up fee, and Platinum charges 0% but requires identity verification and isn't offered in the US. Full numbers are on the fees page.

If you want a card that takes USDT directly, our USDT card guide compares the options.

The verdict

USDT and USDC are freezable by design, and US law now expects that of regulated issuers. For an ordinary holder, the risk is narrow: freezes target addresses tied to theft, sanctions or court orders, and the October 2026 Binance case showed the power working against thieves. The real exposure comes from receiving coins from addresses you don't know and holding them longer than you need to. If you hold stablecoins to spend, get them from a regulated source, check unfamiliar addresses, and know which issuer's terms you are under.

If you'd rather spend USDT or USDC deposited from Solana, Ethereum, Base, Polygon and more as a dollar card balance, see how SolCard works.

FAQ

Can Tether freeze my USDT?

Yes. Tether's terms let it freeze tokens when required by law or when it "determines it is prudent to do so." On Ethereum and Tron it does this by blacklisting an address in the USDT contract, per BlockSec. Only the blacklisted address is affected.

Can USDC be frozen?

Yes. Circle's USDC terms let it block addresses it believes "may be associated with illegal activity" and freeze the USDC there, "temporarily or permanently." Circle froze more than $800 million in USDC after the October 2026 Binance hack, per CNBC.

Can frozen USDT be unfrozen?

It can be. The USDT contract has a removeBlackList function that lifts a freeze, per BlockSec. For stolen funds, the route CNBC describes is law enforcement working with the issuer after a court order or seizure warrant, per CNBC.

How do I know if my USDT address is frozen?

Look the address up on Etherscan or Tronscan, or use BlockSec's free freeze checker, per BlockSec. Check each chain separately, because the Ethereum and Tron blacklists are independent.

Can bitcoin be frozen like USDT?

Not by an issuer, because bitcoin has none. That is why bitcoin stolen in the Binance hack was harder to recover than the stablecoins, per CNBC. An exchange can still restrict an account that holds bitcoin.

Does a stablecoin freeze affect my crypto card?

A token freeze applies to an address holding the token. A prepaid card that converts deposits into a fiat balance isn't holding the token, so a token freeze doesn't apply to that balance. Coins still in your wallet are exposed, and the card program has its own terms.
