This freeze data is about USDT, not USDC

A stablecoin issuer can block an address from moving its tokens, and our evidence shows how Tether does it with USDT. Perhaps a transfer landed from an address you don't recognize, or a platform held your account after a USDC deposit. Every number below comes from our live record of USDT freezes on Ethereum and TRON, built since 2026-07-14. We have no matching count for USDC. What carries over is the method for checking an address yourself on a block explorer.

How an issuer blocks a stablecoin address

A stablecoin's balance lives inside the token's own contract: one number per address, whether the token follows the ERC-20 standard on Ethereum or the matching TRC-20 standard on TRON. A deposit adds to that number, and nothing in the standard keeps a new transfer separate from funds already sitting in the address. Tether freezes an address through a multisig proposal that is later executed. Our tracker watches those proposals and flags the target address before the freeze executes. Since mid-2026 it has flagged 1,067 wallets. For 1,066 of them we know the outcome, and Tether went on to freeze 1,061, so 99.5% of the addresses we flagged were in fact frozen.

Picture two addresses, one on TRON and one on Ethereum, that each receive the same kind of flagged deposit (a made-up example). In our tracker the TRON side loses access first in the typical case: the median gap between our flag and Tether's freeze is 5 minutes on TRON against 33 minutes on Ethereum. Combined across both chains, the typical lead time is 6 minutes, and the slowest 10% of cases take up to 3.2 hours.

The TRON and Ethereum gap, and what happens to a wallet's counterpart

Of the 1,067 wallets we have flagged since mid-2026, 969 came from Tether's TRON proposals and 88 from Ethereum proposals, which lines up with the shorter TRON lead time above. A separate group of 4 wallets was frozen for a different reason. Each was the same wallet on two chains: one private key controls a matching address on both networks, and when Tether froze the address on one chain, the freeze reached its twin on the other chain without a new proposal.

TRON: 969 wallets flagged from Tether's TRON proposals, a median 5 minutes before the freeze executed.
Ethereum: 88 wallets flagged from Tether's Ethereum proposals, a median 33 minutes before the freeze executed.
Cross-chain twins: 4 wallets frozen because the same address, controlled by the same key, had just been frozen on another network.
Funds involved: $436.3 million held across the flagged wallets at the moment of freeze.

Checking any address on Etherscan or Tronscan

The check itself doesn't depend on which stablecoin you're looking at. These steps work for a USDT address, a USDC address, or any other token built on the same standards.

Confirm the contract first. Genuine USDT runs from one contract per network, TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t on TRON and 0xdAC17F958D2ee523a2206206994597C13D831ec7 on Ethereum. The same principle holds for any token: compare the address you're checking against the contract the issuer publishes for that network before you trust what you see.
Open the address on the matching explorer. Tronscan shows the sender, recipient, token contract, amount and time of every TRON transfer; Etherscan shows the same fields for Ethereum.
Read the transfer history as well as the balance. A token balance is one number per address, and a deposit merges into it, so the balance alone cannot show whether the address, or any address that sent to it, has been frozen. The history shows each sender and the time of each transfer, which is what you compare against the freeze tracker in the next step.
Cross-check the address, and the senders you found in its history, against our live USDT freeze tracker, which lists every wallet we have flagged so far. For a broader risk read, run the address through the wallet checker.

What our tracker can't say about USDC

Our freeze tracker is built from Tether's own multisig proposals. Tether publishes those proposals without the target address or exact amount until the freeze executes, so a holder gets no public warning from Tether in time to move funds, and the lead times above show how short the window is even when we flag the address first. All of this describes Tether's process only. We have not published an equivalent proposal-based tracker for USDC. If the address you're checking holds USDC, the explorer steps still apply: confirm the contract and read the transfer history. If the balance looks stuck, that alone is not a verdict. Run the address through the wallet checker, and if the result is still unclear, do not rely on the funds until the platform or issuer confirms their status.

Frequently asked questions

Can USDC be frozen the way USDT is?

A stablecoin issuer can block an address from moving its tokens at the contract level. Tether does this with USDT, and we track every USDT freeze as it happens. We do not have equivalent freeze statistics for USDC, so every number in this article describes USDT. What carries over to USDC is the explorer check: confirm the contract and read the address's transfer history.

How do I check if an address is frozen on Etherscan or Tronscan?

Confirm the token contract first by comparing it against the contract the issuer publishes for that network. Then open the address on Tronscan for TRON or Etherscan for Ethereum and read the transfer history as well as the balance. A balance is one number per address, so it cannot show on its own where a deposit came from. If the balance looks stuck, run the address through the wallet checker.

How much warning do you get before Tether freezes an address?

Very little. Tether publishes its freeze proposals without the target address or exact amount until the freeze executes. Our tracker flags the address first, and the median gap between our flag and the freeze is 5 minutes on TRON and 33 minutes on Ethereum. Combined, the typical lead time is 6 minutes, and the slowest 10% of cases take up to 3.2 hours.

How many USDT freezes has TrustSniffer tracked?

Since mid-2026 our tracker has flagged 1,067 wallets from Tether's multisig proposals. We know the outcome for 1,066 of them, and Tether went on to freeze 1,061, so 99.5% of flagged addresses were frozen. Those wallets held $436.3 million at the moment of freeze.
