Class Action Filed Against Circle Internet Group Over Unfrozen Drift Protocol Exploit Funds

Circle Internet Group, the issuer of USDC, is facing a class action lawsuit over its alleged failure to halt the movement of stolen funds tied to the Drift Protocol exploit. The lawsuit was filed by Drift investor Joshua McCollum at the US district court in Massachusetts, representing over 100 impacted users. The core question is whether Circle had both the capability and the obligation to intervene while the exploit was underway. The legal action traces back to the April 2026 breach of Drift Protocol, a Solana-based decentralised exchange. Attackers drained roughly $285 million. A significant portion of those funds, estimated at around $230 million, was rapidly converted into USDC. The funds were then moved across chains, primarily from Solana to Ethereum, using cross-chain infrastructure. These transfers were not instantaneous. They played out over several hours, split across more than 100 transactions. This timescale forms the crux of the lawsuit. Plaintiffs argue that Circle had a clear window to act. The claim states the company could have frozen the affected wallets or halted the transfers, thereby limiting the damage. Instead, the funds kept 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 both the time and the technical means to do so. Meanwhile, Drift plans a $147.5 million recovery effort backed by future revenue. I will be watching how the court interprets the obligations of a stablecoin issuer in these scenarios. The outcome could set a precedent for how quickly intermediaries are expected to respond during active exploits.
