Resolv Labs Faces $25M Exploit as USR Stablecoin Minting Mechanism Compromised

On March 22, 2026, Resolv Labs reported a significant security breach where an attacker exploited the minting mechanism of its USR stablecoin, generating approximately 80 million uncollateralized tokens. The attacker gained access to the protocol's private keys, allowing them to mint the tokens with only $100,000 to $200,000 in collateral. Following the minting, the attacker swiftly converted the USR into Ethereum, extracting around $25 million in value. The exploit caused USR to depeg from its $1 value, dropping as low as $0.14 before partially recovering. Resolv Labs has since paused all protocol functions and destroyed 9 million of the illegally minted tokens to mitigate further impact. The incident highlights vulnerabilities in DeFi protocols, particularly regarding off-chain components and minting controls. Investigations are ongoing to assess the full scope of the damage and to recover lost funds.

Key Points: • An attacker exploited Resolv's minting mechanism to create 80 million unbacked USR tokens. • The exploit resulted in a loss of approximately $25 million, with USR dropping to $0.14. • Resolv Labs has paused all operations and destroyed 9 million illegally minted tokens.
