According to an official update from Resolv Labs, regarding the illegal minting incident caused by private key leakage on March 22, 2026, approximately 46 million (about 57% of the total) illegally minted USR stablecoins have been permanently removed from circulation. This operation was carried out through a combination of destruction and blacklisting, ensuring that addresses associated with the attacker no longer hold illegal assets that can be further transferred or exchanged. Previously, the attacker gained privileged private keys in the AWS KMS environment and illegally minted 80 million USR with less than $200,000 in collateral, causing USR to depeg and resulting in approximately $23 million in losses.
