Circle Failed To Freeze $420M in Illicit USDC Since 2022

In an April 3, 2026 X post, ZachXBT alleged Circle failed to freeze $420M in illicit USDC activity dating back to 2022, but the research brief for this run does not independently verify that aggregate and does not include a public response from Circle.

Cointelegraph reported that ZachXBT described 15 cases in which Circle allegedly had several hours or days to act, and the outlet said Circle had not immediately responded before publication. That is why the central claim in this story remains an accusation from one public thread rather than a confirmed enforcement record.

What Circle’s own terms show

Circle’s USDC Terms say the company may block certain addresses and may freeze associated USDC if it determines an activity may be illegal or otherwise violate the terms. Those terms do not prove ZachXBT’s allegation, but they do document that Circle reserves the contractual ability to stop transfers and immobilize tokens.

The same USDC Terms say Circle may freeze USDC or surrender the related dollars when it receives a legal order from a valid government authority, and they add that USDC is issued and redeemed under a blocklisting policy. On the evidence available here, the dispute is not whether Circle has a freeze mechanism, but whether it used that mechanism quickly enough in the cases ZachXBT highlighted.

Why the criticism is about enforcement, not capability

A March 27, 2025 DOJ forfeiture complaint gives a concrete example of Circle using that authority: the filing says Circle Internet Financial will permanently blocklist or freeze USDC tied to a seized wallet and then wire the dollar equivalent to a government-controlled bank account. That court filing is narrower than the X thread, but it shows the freeze-and-remit process exists in practice, not only in policy language.

Read together, Circle’s terms, the DOJ complaint, and Cointelegraph’s summary of ZachXBT’s thread support a narrower conclusion than the headline alone suggests: Circle’s documented capability to freeze USDC is real, while the full allegation about historical misses remains unverified in this research run. That makes this a compliance challenge to Circle’s response timing, not a settled finding that every cited flow should have been frozen.

The debate lands in a stablecoin market that DefiLlama sized at $315.781B in the research brief, which helps explain why an allegation about issuer intervention attracts attention beyond one X thread. Coinwy readers have been following other trust and exposure questions in Corporate Bitcoin Split: Strategy Holds, Nakamoto Sells, OKZOO’s April-to-May Listing Window Built a Fast Access Ramp for AIOT, and Crypto Derivatives Hit $18.6T in Q1 2026, CoinGlass Says, but this case is narrower: the sourced question is whether Circle’s documented freeze powers were used promptly enough in the cases ZachXBT flagged.
