Haedal Vault Smart Contract Vulnerability: $915.18K Reported Loss

·Historical incident record

Incident Overview

Haedal Protocol’s Vault pools on Sui suffered an exploit due to a hidden cross-version logic flaw from a 2025 upgrade. The attacker used deprecated old deposit paths to mint inflated LP shares and redeemed them via new paths for excess underlying assets, causing ~$915k in direct losses. Haedal has paused the affected contracts, will fully compensate users, and is preparing a patched upgrade.
