Circle Internet Group faces class action over failure to stop Drift Protocol exploit funds

• Circle is accused of failing to freeze exploit-linked transfers.
• Approximately $230 million in stolen funds was routed through Circle’s USDC.
• Drift plans $147.5 million recovery backed by future revenue.

Circle Internet Group, the issuer of the USDC stablecoin, is facing a class action lawsuit over its alleged failure to stop the movement of stolen funds linked to the Drift Protocol exploit.

The lawsuit, filed by Drift investor Joshua McCollum at the US district court in Massachusetts on behalf of over 100 impacted users, centres on whether the company had both the ability and the obligation to intervene as the exploit unfolded.

Lawsuit targets Circle’s role in fund transfers

The legal action stems from the April 2026 breach of Drift Protocol, a Solana-based decentralised exchange, where attackers drained roughly $285 million.

A significant portion of those funds, estimated at around $230 million, was quickly converted into USDC.

From there, the funds were moved across chains, primarily from Solana to Ethereum, using cross-chain infrastructure.

The transfers were not instantaneous. They occurred over several hours and were split into more than 100 transactions.

This detail sits at the centre of the lawsuit.

Plaintiffs argue that Circle had a window of opportunity to act.

According to the claim, the company could have frozen the affected wallets or halted the transfers, limiting the damage. Instead, the funds continued moving until they were fully out of reach.

The case accuses Circle of negligence and of indirectly facilitating the loss by failing to act despite having the technical capability to do so.

This argument is reinforced by previous instances where the company has frozen wallets tied to illicit activity, showing that such intervention is not only possible but already part of its operational toolkit.

At its core, the lawsuit raises a difficult question: when a centralised entity operates within a decentralised system, where does its responsibility begin and end?

Drift’s recovery plan

In response to the exploit, Drift Protocol has outlined a structured recovery plan aimed at addressing user losses while rebuilding the platform’s liquidity and operations.

The protocol is seeking to mobilise up to $147.5 million, with a significant portion backed by Tether and other ecosystem partners.

This figure, however, should not be viewed as immediate compensation.

A large share of the funding comes in the form of a revenue-linked credit facility estimated at around $100 million.

This means the protocol will draw funds over time and repay them using future trading fees and platform revenue rather than distributing the full amount upfront.

To manage user claims, Drift plans to issue a new recovery token, though its official name and final structure are yet to be confirmed.

This token will be distributed to affected users and will represent their share of the recovery pool.

It is expected to be transferable, allowing users to either hold it and wait for gradual repayments or sell it on secondary markets for immediate liquidity, likely at a discount.

The recovery pool itself will not rely solely on external funding.

It is designed to be continuously replenished through multiple sources, including protocol revenue, partner contributions, and any funds that may be recovered from the attackers.

This creates a system where repayments are tied directly to the platform’s ability to restart operations and generate consistent trading activity.

Despite these measures, there remains a clear shortfall.

With total losses estimated at approximately $285 million and recovery efforts targeting up to $150 million, a large portion of user funds is not immediately covered.

This gap highlights that users are unlikely to be fully reimbursed in the near term, and recovery will depend heavily on Drift’s long-term performance.

To support a relaunch, part of the recovery framework is also focused on restoring liquidity.

Incentives and financial support are being directed toward market makers to rebuild order books and improve trading conditions once the platform resumes full operations.

Without sufficient liquidity, even a technically sound relaunch would struggle to attract users back.

Another major shift is the protocol’s decision to move away from USDC as its primary settlement asset and instead adopt USDT.

This change comes after roughly $230 million of the stolen funds were converted into USDC and moved across chains during the exploit.

The switch signals a reassessment of risk and reflects a broader effort to restructure the platform’s core infrastructure following the incident.

Overall, Drift’s recovery plan is built around gradual restitution rather than immediate payouts.

Its success will depend on how quickly the platform can regain user trust, restore liquidity, and generate enough revenue to sustain long-term repayments.
