PANews reported on May 28th that, according to on-chain analyst Yu Jin, 14.981 million GUA (worth $15.18 million at the time) were sold off on-chain nine hours ago after being transferred out of the unlocking contract, causing the price of GUA to plummet by 75%. This GUA was ultimately exchanged for 2,784 ETH ($5.66 million) and stored in three wallets. The project team stated that this GUA unlock was due to a hacker attack, with the funds being transferred to a hacker address that had the same first and last four characters as the intended address.

Previously, Superfortune confirmed a security incident, stating that "addresses in multisignature transactions were tampered with."
