What happened
On July 9, 2025, GMX was exploited for about $42M on Arbitrum. The attacker later returned the funds after accepting a $5M white-hat bounty.
The exploit targeted GMX's older vault logic. After a public bounty offer of 10%, the attacker returned the stolen funds, making this one of the larger successful white-hat recoveries. Recovery does not erase the underlying issue, but it stopped the headline from becoming even worse.
