GUA token, associated with the Manta-incubated project Superfortune, experienced significant price volatility following a security incident on May 27, 2026. The volatility is attributed to an address-poisoning attack that tampered with a multisig transaction address intended for releasing additional unlocked tokens to an airdrop claim contract. The compromised address had no prior interactions with its associated addresses, raising concerns about the integrity of the transaction. The incident led to a sharp 74% decline in GUA's price within 24 hours. Investigations are ongoing, with relevant authorities and incident response teams engaged to address the breach and mitigate further risks.
