Resolv's USR stablecoin depegs after attacker uses a compromised signing key to mint 80M unbacked tokens
On 21 March 2026 an attacker obtained a privileged private key used by Resolv's off-chain minting service, deposited about $100K-$200K in USDC and minted about 80M USR, which the contracts did not cap. They swapped out for about 11,408 ETH, roughly $24.5M, and USR fell to about 26 cents. Resolv paused its app, offered the attacker a 10% bounty and asked holders not to trade USR while it works on recovery.
