Investors Sue Circle for Failing to Freeze Stolen USDC
Circle Internet Financial is now the target of a class action lawsuit filed on April 15, 2026, by a group of Drift Protocol investors who lost funds in the $280 million exploit that occurred on April 1, 2026 — one of the largest hacks in DeFi history.
The lawsuit, brought by law firm Gibbs Mura, accuses Circle of failing to act swiftly to freeze the stolen USDC despite having both the technical capability and contractual authority to do so. Lawyers stated:
“Circle allegedly took no action to freeze the funds, despite having the technical and contractual authority to do so.”
On-chain investigator ZachXBT had earlier criticized Circle, noting the company had approximately six hours to freeze the stolen funds before the attacker moved over $230 million worth of USDC from Solana to Ethereum via Circle’s cross-chain transfer protocol.
The complaint highlights that just nine days before the Drift exploit, Circle froze 16 unrelated wallets in a separate civil case, demonstrating both the capability and willingness to act when it chose to.
Circle’s Defense and the Moral Quandary
In a press conference earlier this week, Circle CEO Jeremy Allaire defended the company’s position. He stated that Circle only freezes USDC wallets when directed by law enforcement or the courts. Acting unilaterally in private matters, according to Allaire, would create a “significant moral quandary” and set a dangerous precedent.
“If there are others that believe that Circle should just step away from what the law says and do its own decisions, I think it’s a very risky proposition.”
Circle has not yet issued a formal comment on the class action lawsuit itself.
Drift Protocol’s Recovery Efforts
Drift Protocol announced on April 16 that it has secured a proposed recovery package of up to $127.5 million from Tether and $20 million from other partners. The structure is intended to support user recovery and facilitate Drift’s relaunch as the largest USDT-based perpetual DEX on Solana.
What This Means for the Market
This lawsuit raises important questions about the responsibilities of stablecoin issuers when large-scale exploits occur. It highlights the tension between strict adherence to legal processes and the expectation for rapid action in the fast-moving world of decentralized finance.
For USDC holders and DeFi users, the case could influence how future exploits are handled and whether stablecoin issuers will face increasing pressure to act more proactively.
Bitcoin (BTC) and Ethereum (ETH) prices have shown limited direct reaction so far, but continued scrutiny of stablecoin issuers could affect broader market confidence in regulated crypto infrastructure.
Investor Takeaway
The lawsuit is in its very early stages. Outcomes will likely depend on whether courts determine Circle had a duty to freeze the funds independently of law enforcement requests. In the meantime, users of USDC and other stablecoins should remain aware of the evolving debate around issuer responsibilities during security incidents.
