[Circle Sued for Failing to Freeze $230 Million in Stolen USDC] According to Cointelegraph, Circle is facing a class-action lawsuit in the U.S. District Court for the District of Massachusetts for failing to freeze stolen funds from the April 1 attack on Drift Protocol. The plaintiffs claim that the attackers transferred approximately $230 million in USDC from Solana to Ethereum via CCTP, and Circle did not intervene. The lawsuit accuses Circle of aiding misappropriation and negligence. Elliptic suspects the attack is linked to North Korea-backed hackers, with the funds converted to ETH and transferred through Tornado Cash.
