Summary
Steadefi is a decentralized leveraged yield farming protocol operating on Arbitrum and Avalanche. On August 7, 2023, an attacker exploited a compromised deployer private key to drain approximately $1.14 million from the protocol's lending vaults across both chains. The protocol subsequently relaunched with enhanced security measures and issued a token-based compensation plan for affected users, though roughly 70% of stolen funds were never recovered.
