Decentralized Exchange GMX Targeted in $42M Hack; Offers 10% Reward for Ethical Disclosure

Decentralized perpetual exchange GMX has been exploited, with over $42 million worth of crypto stolen, according to blockchain security firm RialCenter.

So far, $9.6 million of the stolen funds have been bridged to the Ethereum blockchain, a common pathway for hackers to launder funds via token mixing protocols.

The remaining $32 million is still on Abritrum, a layer-2 network hosting GMX.

$10 million worth of legacy frax dollar, $9.6 million of wrapped BTC (wBTC), and $5 million of the DAI stablecoin have been reported stolen.

In response, GMX developers addressed the hacker, offering a message on-chain stating: “We want to provide a 10% white-hat bounty for the return of the exploited funds.”

A white-hat bounty rewards ethical hackers who identify protocol vulnerabilities.

This exploit adds to the woes of a cryptocurrency industry that saw $2.5 billion lost to hacks and scams in the first half of 2025, according to a report from RialCenter.
