The debate over how far stablecoin issuers should go in policing activity on public blockchains has returned to the center of the crypto market. With a market capitalization of about $78.7 billion, USDC remains one of the most important dollar-backed tokens in circulation, and that scale has intensified questions about whether Circle’s compliance model is too narrow for fast-moving exploit scenarios.
Circle Sticks To A Legal Trigger Standard
Speaking in Seoul on April 13, 2026, Jeremy Allaire said Circle does not freeze wallets on its own initiative and acts only when directed by law enforcement or the courts. That position is broadly consistent with Circle’s public help materials, which state that wallet addresses are blocked only when the company is legally compelled to do so. Circle’s message is clear: the issue is not whether the technology exists, but whether the company has the legal authority to act.
That stance reflects Circle’s effort to frame USDC as a regulated financial product rather than a discretionary enforcement tool. In practice, the company is signaling that rapid intervention during hacks may be possible in theory, but not something it is willing to normalize outside a formal legal process.
The Drift Protocol Exploit Sits At The Center Of The Backlash
The sharpest criticism followed the Drift Protocol exploit on April 1, 2026. Reports from multiple outlets put the size of the attack at roughly $280 million to $285 million. A large portion of that total was denominated in USDC, with more than $232 million reportedly bridged from Solana to Ethereum through Circle’s Cross Chain Transfer Protocol over the course of several hours and more than one hundred transactions.
That timeline became the basis of the case against Circle. Onchain investigator ZachXBT argued that the company had a visible window in which the funds were moving across infrastructure tied to its own stablecoin but still did not intervene. CoinDesk also reported, citing Elliptic, that the exploit was likely linked to North Korean actors, while The Block said Drift and SEAL 911 had reached a similar assessment with medium to high confidence.
The $420 Million Claim Raised The Stakes
The controversy did not stop with Drift. Secondary reports citing ZachXBT said that more than $420 million in illicit USDC flows across 15 documented incidents since 2022 had not been frozen in time. Some coverage used a lower incident count, but the broader accusation was the same: Circle’s enforcement response appeared inconsistent across major cases.
Pressure on Circle grew further after reports that the company froze 16 business wallets in March 2026 in connection with a US civil case, with at least five later unfrozen. For critics, that episode sharpened the contrast. The company appeared willing to move quickly in one legal context while remaining far more restrained during high-profile exploit flows.
Tether Has Been Used As The Benchmark
Much of the comparison has centered on Tether, whose issuer has repeatedly been cited as more aggressive in blocking suspicious funds. Ledger’s official incident report states that USDT tied to the December 14, 2023 attack was frozen the same day. In the Remitano case, Tether was reported to have frozen roughly $1.4 million in USDT. Tether also announced in November 2023 that it had voluntarily frozen $225 million in USDT as part of an investigation involving the US Department of Justice and OKX.
Those examples have reinforced the market view that Tether is willing to act faster and more proactively when suspicious flows emerge. Circle’s answer has been that a broader use of freeze powers would open a much larger debate about private control over public blockchain money.
The Bigger DeFi Question Is About Private Power
Not everyone sees slower intervention as a policy failure. Omid Malekan, who teaches at Columbia Business School, has argued that if stablecoin issuers begin going beyond what the law requires, they risk undermining trust in decentralized finance by turning private companies into ad hoc gatekeepers. In that reading, the dispute is not only about stopping crime faster. It is also about how much unilateral authority a stablecoin issuer should have over a digital dollar used across open networks.
Given USDC’s role as the second-largest dollar stablecoin, the issue now extends well beyond Circle itself. CoinGecko data for April 13, 2026 showed USDT at roughly $184.4 billion in market value and USDC at about $78.7 billion, underscoring how decisions around freezes, compliance, and issuer discretion can shape confidence across the broader stablecoin market.
