Circle’s Compliance Claims Challenged by ZachXBT on X

Key Highlights:

• Circle has claimed it has always worked closely with the government to build a safe financial space. 
• ZachXBT has accused Circle of delaying freezing addresses that were tied to Lazarus Group and Garantex.
• The dispute highlights the tension between corporate compliance and on-chain enforcement speed. 

This week, a clash between crypto firms and regulators was observed on social media when blockchain sleuth ZachXBT questioned Circle’s claims of working closely with the government. This disagreement and dispute indicates a bigger issue: how stablecoin issuers can follow rules while staying true to crypto’s open and transparent spirit.

Circle’s Big Moment

On Monday August 18, 2025, the issuer of USD Coin (USDC) took over X to describe its 12-year journey in this industry. In this post which was reflective, the company emphasized its strategy of working directly with the government and regulators to make what it calls the “internet of money” a reality.

“You’ve got to work with governments. There’s no way around it,” the post quoted Circle CEO Jeremy Allaire, linking to a profile that described Circle’s long road towards earning trust, shaping policy and building a safer financial system. The message positioned Circle as a responsible actor who is committed to transparency and oversight. All of this at a time when regulators are scrutinizing stablecoin issuers more intensely.

The Clap Back from ZachXBT

Not everyone in the industry was convinced. Within hours of the post being online, ZachXBT, a well-known blockchain sleuth fired back. To the post made by Circle, ZachXBT replied back, where he accused Circle of overstating its promptness in responding to government concerns.

From the response on X (formerly known as Twitter) , it can be deduced that the sleuth’s allegation centers on two episodes:

• The Lazarus Group case: The hacking group in North Korea, sanctioned by the U.S. Treasury, has been linked to some of the largest DeFi exploits in the history (Bybit exploit, Ronin Network, Horizon Bridge and Atomic wallet exploits). While Tether and other stablecoin issuers took immediate action and blocked the sanctioned addresses tied to Lazarus. ZachXBT claims Circle delayed the exact process for months before doing the same.
• The Garantex case: The Russian crypto exchange Garantex was sanctioned by OFAC in 2022 for facilitating money laundering. ZachXBT pointed out that Circle did not freeze sanctioned Garantex-linked addresses immediately even though the U.S. authorities had highlighted the takedown in press releases.

Why the Clash Matters?

If you look at the both the matters closely, you will figure it out that the dispute is not just about compliance speed but it reflects a broader contradiction faced by stablecoin issuers. On one hand, firms like Circle want to be seen as partners to governments and banks, making a way for mainstream adoption of digital dollars. On the other hand, crypto purists and watchdogs demand concrete proof that issuers are acting decisively when sanctioned entities are involved.

This criticism from the blockchain sleuth indicates that Circle’s narrative of seamless cooperation may be a little too over simplified. Regulators expect not only eventual compliance, but it also requires timely action from the stablecoin issuers to prevent any kind of misuse by the bad actors. Any delay in such matters can be framed as reluctance, or worse, it can also be framed as prioritizing business relationships over international security measures.

For Circle, which has promoted its stablecoin USDC, as the more regulation-friendly stablecoin compared to Tether, these accusations attack its reputation. The company has often highlighted its focus on transparency, audits, and cooperation with governments. However, critics argue that such claims mean little unless they are being backed by clear proofs and consistent enforcement.

As of now, there has been no response from Circle for the accusations made by the blockchain sleuth. Whether the company issues a clarification or lets the comment slide could hint as to how it plans to manage criticism as regulatory pressure intensifies.
