Chain detective ZachXBT published an article on the X platform questioning Circle's handling of the security incident, stating that "history has proven Circle to be a bad actor." ZachXBT stated that approximately 10 hours ago, the SwapNet contract on the Base network was attacked, resulting in a loss of approximately $13 million USDC. About $3 million of this USDC remains in an address that Circle could freeze (0x6cAad74121bF602e71386505A4687f310e0D833e), but no effective action has been taken to address this issue. He further questioned Circle's failure to take timely action to protect user interests after the attack on user assets, and asked why developers are still willing to build applications based on USDC, arguing that its centralized risks and governance methods have impacted trust within the ecosystem.
