GMBL.COMPUTER is an Arbitrum-based DeFi gambling protocol that launched in September 2023 and was exploited within hours of going live, losing approximately 471 ETH (~$770,000) due to an off-chain server signature vulnerability and a flaw in its referral system. The exploiter returned roughly half of the stolen funds (235 ETH) after the team issued a conditional bug bounty offer. The protocol operates with an anonymous team, no disclosed security audits, no regulatory licensing, and as of 2025 shows near-zero trading volume and minimal on-chain activity.
