The Resolv Hack: How One Compromised Key Printed $23 Million
Summary
Chainalysis documents the Resolv hack where an attacker used a privileged off-chain signing key to mint 80 million USR, extracting about $25 million and causing a depeg. The analysis emphasizes that the vulnerability lay in off-chain infrastructure rather than the on-chain contract, and it advocates real-time on-chain monitoring and automated response as essential defenses for DeFi protocols and security-conscious SMBs.
