Can Tether or Circle Freeze Your Stablecoins?

Yes. Tether and Circle can both freeze USDT and USDC held at any Ethereum address, including a self-custody wallet, because each token's contract has an administrator-controlled blacklist. On Ethereum alone, Tether's contract has logged 3,178 blacklisting events since November 2017 and Circle's USDC contract 906 since June 2020, according to a count of the contracts' public event logs run on October 23, 2026.

What a freeze is at the contract level

Both tokens are programs. Their code decides whether a transfer succeeds, and both contain an administrator-controlled blacklist. The details differ, and the differences matter for what a freeze actually does to your balance.

Feature	USDT on Ethereum (TetherToken)	USDC (Circle's FiatToken code)
Who can blacklist	The contract owner calls addBlackList(address)	The blacklister role calls blacklist(address)
Blocks the blacklisted address from sending	Yes: transfer requires the sender not be listed; transferFrom requires the "from" address not be listed	Yes: transfer, transferFrom and approve all require the caller not be blacklisted
Blocks others from sending to the address	Not in the verified source: transfer has no check on the recipient	Yes: transfer requires the recipient not be blacklisted
Can the issuer destroy the frozen balance?	Yes: destroyBlackFunds(address) sets the balance to zero and reduces total supply, for a listed address	Not in the repository code read for this page: the flag blocks movement; the balance stays recorded
Can the issuer pause everything?	Yes: pause() by the owner halts transfers	Yes: pause() by the pauser role
How a freeze is undone	removeBlackList(address) by the owner	unBlacklist(address) by the blacklister

The USDT facts come from the verified source of the Ethereum contract (0xdAC17F958D2ee523a2206206994597C13D831ec7) as served by Sourcify, compiled with Solidity 0.4.18. The USDC facts come from Circle's public stablecoin-evm repository on GitHub. That repository is the current master branch of Circle's code, not necessarily the exact bytecode deployed at the USDC address, so read the USDC column as the design Circle publishes and not as a byte-level audit of the live contract. In Circle's newer version, the blacklist flag is stored in the top bit of the same storage slot as the balance, so the number of tokens is unchanged while the flag blocks any change to it.

Three practical consequences follow.

1.A freeze is not a seizure by default. Under both designs the tokens remain at the address. Whether they are later released, burned or reissued is a separate decision by the issuer, following whatever process it follows.

2.Tether has a burn function that Circle's published code lacks. The destroyBlackFunds function exists so that tokens at a listed address can be removed from supply. What the issuer does with the value after that is a matter for its policy and the law, and the code does not say.

3.Receiving from a frozen address is treated differently. In USDC's design, a transfer to a blacklisted address fails outright. In the USDT source read here, the check is only on the sender, so a transfer to a listed address can succeed, after which the tokens cannot be moved out.

What the issuers' own terms say

The contract gives the power. The terms say when it will be used, to the extent that they say anything.

Tether. The Tether terms of service, as retrieved October 23, 2026, give Tether broad contractual rights. They say Tether may "freeze any Tether Tokens held by you" and may terminate your wallet (section 2); may impose "freezing or confiscation of any Fiat, funds, property" and "blacklisting any Digital Tokens Address which holds Tether Tokens" for a prohibited use (section 8); and may "bar transactions from or to" users (section 9). They also allow Tether to report suspected prohibited uses "without providing any notice to you," to seize and deliver property to a government where circumstances warrant (section 8), and to suspend services "when Tether is directed to do so by any Government" (section 6). On redemption, section 4.1 says you "must be a verified customer of Tether" and that the redemption right is "a contractual right personal to you."

Circle. Circle's USDC terms, which show "Last Updated: October 15, 2026," say Circle "reserves the right to 'block' certain USDC addresses" and may "block the transfer of USDC to and from an address on chain as permitted under the blocklisting policy" (section 13). If you send to or receive from a blocked address, Circle "may freeze such USDC and take steps to terminate your USDC Account" (section 13). Circle may also be required to freeze USDC or surrender associated dollars "in the event it receives a legal order from a valid government authority." Only holders with a Circle Mint account can redeem directly with Circle (sections 2 and 13). A separate Circle risk-factors page, last updated October 27, 2023, adds that freezing is governed by its blacklisting policy and applied "in extraordinary circumstances."

Two differences show up when the quotes sit next to each other. Tether's terms reach any user who breaches them for any prohibited use and include "confiscation." Circle's terms tie blocking to its published blocklisting policy and to legal orders, and Circle's risk-factors page uses the phrase "extraordinary circumstances." Neither document, as retrieved, sets out an appeal procedure. Circle's blocklisting policy is linked from its risk-factors page as a PDF that could not be opened for this page, so its grounds are not summarized here.

What the law now requires: the GENIUS Act

Freeze capability used to be a design choice. For US-facing payment stablecoins it is becoming a statutory requirement. The GENIUS Act, Public Law 119-27, contains three provisions, read from the GovInfo text.

A definition. Section 2 defines a "lawful order" as a final and valid writ, process, order, rule, decree, command or other requirement under Federal law, issued by a court of competent jurisdiction or an authorized Federal agency, that "requires a person to seize, freeze, burn, or prevent the transfer of payment stablecoins issued by the person," that specifies the coins or accounts "with reasonable particularity," and that "is subject to judicial or administrative review or appeal as provided by law."

A condition for issuers. Section 4 provides that a permitted payment stablecoin 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." Another part of section 4 requires an issuer's anti-money-laundering program to include "technical capabilities, policies, and procedures to block, freeze, and reject specific or impermissible transactions that violate Federal or State laws, rules, or regulations."

A condition for foreign issuers. Section 3 makes it unlawful, starting three years after enactment, for a digital asset service provider to offer a payment stablecoin to a person in the United States unless a permitted issuer issued it; and it makes it unlawful to offer a foreign issuer's stablecoin unless that issuer "has the technological capability to comply, and will comply," with lawful orders and any reciprocal arrangement.

Two features of the definition matter for a holder. The order must be reviewable, and it must name coins or accounts with reasonable particularity, which limits what a lawful order can reach. The statute is silent, in the parts read, on a private right for an affected holder to demand release. Our fuller reading of the statute is in the GENIUS Act guide, and the practical differences between the two coins are compared in our USDT versus USDC guide.

The count: how often it has happened, on Ethereum and Tron

Both contracts emit an event each time an address is listed or unlisted, and Ethereum logs are public. Counting those events gives a lower bound on how often each issuer has exercised the power, on this one chain. The method is described below so that anyone can reproduce it.

Year	USDT: addresses blacklisted	USDT: removed	USDT: balances destroyed	USDC: addresses blacklisted	USDC: removed
2017	1	1	1	0	0
2018	8	0	8	0	0
2019	7	0	9	0	0
2020	232	7	129	1	0
2021	312	27	205	24	2
2022	250	11	222	126	2
2023	440	7	86	60	1
2024	755	23	216	54	6
2025	657	173	255	215	125
2026 to Oct 22	516	98	165	426	90
Total	3,178	347	1,296	906	226

Read as follows.

Tether on Ethereum. 3,178 blacklist events covered 3,168 distinct addresses. Replaying the add and remove events in block order leaves about 2,825 addresses currently listed. The 1,296 destroy events removed a total of roughly 858.9 million USDT from supply on Ethereum, (1,295 of the events were non-zero) across 1,199 distinct addresses; the largest single event was about 87.5 million USDT. By year, destroyed amounts rose from about $113 million in 2021 to about $431 million in 2025 and about $144 million in 2026 so far.

Circle on Ethereum. 906 events covered 852 distinct addresses. Replay leaves about 656 currently listed. Circle's published code has no destroy function, so there is no matching column.

Trend. Both counts rose through 2025 and 2026. In the 365 days to October 22, 2026 there were 642 USDT blacklist events and 101 removals, and 529 USDC blacklist events and 90 removals. Removals also rose, which shows freezes are not always permanent. Over the whole record USDT logged 347 removals against 3,178 additions (about 11 percent) and USDC 226 against 906 (about 25 percent); the logs do not say why an address was removed.

Cross-check. To check the replay, 48 addresses (24 per token, half predicted listed and half predicted unlisted) were queried directly on the contracts on October 23, 2026, and all 48 matched the replay.

What the count does not show

Two chains at most. The Ethereum tables cover Ethereum mainnet only. Tron is counted separately below for USDT. USDC on other networks, and USDT elsewhere, were not counted, so every total here is a floor.

Events, not owners. An address is not a person. An exchange omnibus wallet or a protocol contract can be one address with many users behind it.

No reasons. The logs record that a listing happened, not whether it followed a court order, a sanctions designation, a hack response or an error.

Only some are theft cases. Neither issuer's data breaks listings down by cause, so these numbers should not be read as a count of recovered theft.

Data source. Ethereum events were pulled from a public RPC endpoint (rpc.mevblocker.io) by event signature and contract address; Tron events from the public TronGrid API. The contract addresses and event signatures are in the sources below.

The same count on Tron

A large share of USDT circulates on Tron, whose USDT contract (TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t) has the same blacklist functions and emits the same events. Its public event history, pulled from the TronGrid API on October 23, 2026 with the same method, shows a larger and faster-growing record than Ethereum's.

Year	Tron USDT: addresses blacklisted	Tron USDT: removed	Tron USDT: destroy events
2020 (from Jun 26)	14	0	21
2021	24	2	18
2022	315	3	225
2023	275	17	27
2024	1,225	60	73
2025	3,509	210	455
2026 to Oct 22	3,669	695	449
Total	9,031	987	1,268

The 9,031 listing events covered 8,994 distinct addresses, the 1,268 destroy events covered 1,224 addresses and removed about 607.0 million USDT, and replaying the add and remove events in order leaves about 8,020 addresses currently listed. In the 365 days to October 22, 2026 there were about 4,119 additions and 728 removals. Tron's USDT history starts in June 2020, so it covers fewer years than Ethereum's, yet it has nearly three times as many listing events.

Put together, the two chains show 12,209 USDT blacklist events and about 1.47 billion USDT destroyed from listed addresses (858.9 million on Ethereum, 607.0 million on Tron). Tether is also deployed on other networks that this page did not count, so those totals remain a floor. The trend is the more telling number: Tron's additions grew from 315 in 2022 to 3,669 in the first ten months of 2026, and removals grew faster in relative terms, from 3 to 695. The logs cannot say why. More enforcement, more cooperation with authorities, more exploit responses and a change in how routinely the tool is used would all produce the same curve, and the counts carry no cause field.

How to count it yourself

1.Take the contract address and compute the Keccak-256 hash of the event signature: AddedBlackList(address) and RemovedBlackList(address) for USDT; Blacklisted(address) and UnBlacklisted(address) for USDC.

2.Query eth_getLogs for that address and topic, in block ranges small enough for your provider, from deployment to the latest block.

3.For USDT the listed address is in the log data. For USDC it is the first indexed topic.

4.To know who is listed now, replay the events in order, or call getBlackListStatus on the USDT contract or isBlacklisted on USDC for a single address.

Block explorers also expose a "Read contract" tab with these functions, which is the simplest way to check one address.

Who bears the risk, and what recourse the sources show

The sources show a clear allocation of power. They show much less about remedy.

Question	USDT	USDC
Can the issuer freeze an address on its own?	Contract: yes. Terms: broad rights, including for breach of the prohibited-use terms	Contract: yes. Terms: "in extraordinary circumstances" under its blocklisting policy, and on legal orders
Can a self-custody holder be frozen?	Yes. The list covers any address	Yes. The list covers any address
Can receiving from a frozen address cause trouble?	Terms allow Tether to bar transactions from or to users	Terms say Circle may freeze USDC and terminate your account if you send to or receive from a blocked address
Is there a published appeal process?	None found in the terms retrieved	None found in the pages retrieved; the blocklisting policy PDF was not opened
Is redemption available to anyone?	Only verified Tether customers	Only Circle Mint account holders redeem directly
What does US law add?	Lawful orders must be reviewable; issuers must be able to comply	Same

Exposure is not equal for everyone. A holder who bought on a regulated exchange and sells on the same exchange rarely touches a frozen address. A holder who receives a payment from an unknown address or interacts with a smart contract that later turns out to be linked to an exploit carries more. Two habits reduce the chance of ending up next to a frozen address: be cautious about unsolicited transfers, and keep the records of where your tokens came from. Our guide to token approvals covers the permissions side, and the comparison of stablecoin designs places freeze power among the other differences. Whether an issuer's reserves are verifiable is a separate check, laid out in the proof-of-reserves checklist, and the stablecoins topic hub collects the rest. For what a wallet's keys do and do not control, see the wallet guide.

Do other dollar stablecoins carry the same lever?

The freeze power is a design choice, not a property of stablecoins. Reading the verified Ethereum sources for four other dollar tokens, served by Sourcify on October 23, 2026 after resolving each proxy to its current implementation, shows how the choice differs. The table reports what the code shows and says nothing about how, or whether, an issuer uses it.

Token (Ethereum)	Verification level at Sourcify	Account freeze in the code?	Who holds it	What a freeze blocks	Destroy or claw back?
FDUSD	Full match	Yes: freeze(address) and unfreeze(address), with a public frozen mapping	The contract owner	Transfers and approvals to or from a frozen account	No owner-forced burn of another account in the code read; the owner can burn its own balance
USD1	Full match	Yes: the same freeze and unfreeze pair	The contract owner	Transfers and approvals involving a frozen sender, recipient or caller	No owner-forced burn of another account in the code read
RLUSD	Partial match	Yes: accounts can be paused, a "frozen" state	A pauser role	Transfers from, to or by a paused account	Yes: a clawback role can burn from a frozen account (code comment: "allow burn when account is frozen (clawback)")
USDS	Partial match	None found: the implementation has an authorization list for administrators and no per-holder block	Not applicable	Not applicable	Not applicable

Three cautions. A partial match means only some of the contract's files were verified, so the RLUSD and USDS rows describe what could be read. The contracts are upgradeable proxies, so an issuer can change the code behind the address, and the table is a dated reading and not a promise. And the absence of a freeze function in a token's own contract does not mean the token is unfreezable in practice: assets that depend on other contracts, custodians or off-chain redemption can be restricted at those layers. The point of the table is narrower. USDT's design includes a function that destroys a listed account's balance. In the code read, FDUSD and USD1 freeze without a forced burn, RLUSD has an explicit clawback role, and USDS has no per-holder block. Holders who care about the difference can read a token's contract on a block explorer before holding it. DAI and PayPal's PYUSD were not read for this page because their verified sources could not be retrieved from the same service.

If your stablecoins are frozen

This is general information, not legal advice. These are the routes the sources support.

Confirm it. Use the read functions above or a block explorer to check whether the address is listed. A failed transfer can also come from low gas, an approval problem or a paused contract.

Go to the right party. If the tokens are on an exchange, the exchange's support process comes first. If they are in your own wallet, the issuer is the party that holds the lever, and its terms are the starting point.

Ask a lawyer. The terms limit what you can demand. A qualified lawyer can say what your jurisdiction allows, including whether a court order is involved.

If you were scammed. Report it through official channels. Our guide on how to report a crypto scam lists them. Do not pay anyone who promises to unfreeze or recover funds for a fee; that is a common second scam and our recovery scams guide explains the pattern.

None of the sources reviewed promises that a frozen balance will be released, and this page does not either.

Both sets of terms were retrieved on one date and can change. The statute behind the freeze requirement is read section by section in the GENIUS Act guide, which is the better place to check whether a rule you are relying on is still current.

Frequently Asked Questions

Can Tether freeze USDT in my wallet?

Yes. The USDT contract on Ethereum lets the owner add any address to a blacklist, after which that address cannot send USDT. The Tether terms also reserve the right to freeze tokens and blacklist addresses for prohibited uses. Self-custody does not exempt an address.

Can Circle freeze USDC?

Yes. Circle's FiatToken design has a blacklister role that can block an address from sending or receiving. Circle's terms say it may block addresses under its blocklisting policy and freeze USDC on valid legal orders. Its risk factors page says this is used in extraordinary circumstances.

How many USDT and USDC addresses have been frozen?

A count of the public contract events on October 23, 2026 found, on Ethereum, 3,178 USDT blacklist events (3,168 distinct addresses) and 906 USDC events (852 distinct addresses), and on Tron 9,031 USDT events (8,994 distinct addresses). Other blockchains were not counted, so these are lower bounds.

Does a frozen balance get destroyed?

Not automatically. In both designs the tokens stay at the address. Tether's contract has a function that can destroy the balance of a listed address, and its logs show 1,296 such events on Ethereum and 1,268 on Tron. Circle's published code reviewed here has no such function.

Does the GENIUS Act require stablecoin issuers to be able to freeze?

Yes for permitted payment stablecoin issuers. The statute allows issuance only if the issuer has the technological capability to comply, and will comply, with any lawful order, defined as a reviewable court or agency order to seize, freeze, burn or prevent transfer, with reasonable particularity.

Is there an appeal if my address is frozen?

The terms and pages retrieved for this guide do not describe an appeal process. Circle's blocklisting policy PDF could not be opened. If you are affected, the sensible step is to read the issuer's current policy and speak to a qualified lawyer.

Do all stablecoins have a freeze function?

No. In the verified Ethereum code read for this page, FDUSD and USD1 have an owner-controlled freeze, RLUSD has an account-pause state with a clawback role, and the USDS implementation has no per-holder block. The design differs by token, and contracts behind proxies can be upgraded.
