With no on-chain maximum mint cap enforced, the attacker deposited ~$100K–$200K in USDC and used the stolen key to mint 80 million USR tokens (~$25M). The unbacked tokens were converted to wstUSR, swapped through DEX pools into ETH, and extracted before the protocol could respond. USR's peg collapsed 80% before Resolv halted operations. The post-mortem highlights that 18 smart contract audits couldn't prevent an off-chain infrastructure compromise, and argues that real-time on-chain monitoring (specifically Chainalysis Hexagate) with automated pause triggers is now essential for DeFi protocols relying on privileged off-chain signers. ## Full article daily.dev links to this article rather than hosting it.
