The GMX exchange hack was confirmed on July 9 by DeBank. It sparked panic among the investors and a steep fall in its token price. 

Suspicious outflow sparks concerns 

The very first signal of trouble came when blockchain trackers noticed a sudden and suspicious outflow of funds from their wallets. A large amount of digital assets including WETH, WBTC, USDC, DAI, LINK, FRAX and more  were moved to a suspicious wallet starting with “0xdf3340a4…”. 

This wallet showed an 800%+  increase in value that confirms that something is seriously happening wrong. Security companies like ExVul and data providers like DeBank suddenly flagged the activity as a potential breach. Later on it was confirmed by the marketplace about GMX exchange hack.

Later, GMX exchange hack was discovered that the attacker had funded their wallet via Tornado cash days in advance which suggests that it was a pre planned and well executed.

Marketplace shared some immediate taken steps by them that are:

• The platform disabled the trading and GLP mint/redeem functions on Arbitrum and Avalanche. 

• Confirmed that GMX V2, tokens and other trading pools will remain unaffected. 

• It promised to the investors that the full details of the incident will be disclosed soon, as soon as all findings are validated. 

What all was stolen? 

The hacker didn’t just steal platform’s one coin but they hacked a mix of major visual assets like $9.6M in USDC, $8.5M in WETH, $10.4 in Frax Dollar , $9.6M in WBTC and smaller amounts of UNI, LINK, DAI and other tokens.

Exchange speaks out after silence

It was also discovered that the attacker used Circle’s CCTP(Cross- Chain Transfer Protocol) to move USEDC from Arbitrum to Ethereum(ETH) and later converted to DAI. This has triggered criticism among the people involved with the community and are questioning why Circle didn’t freeze the stolen USDC in time.  

Token price drops, Users panic 

As expected the panic set in fast. The platform’s token price dropped by more than 10% falling to around $12.50 within 24 hours. This news caused a quick sell-off as many users rushed to exit

Crypto breach continue to be a feature of the digital asset landscape

In the first half of the year 2025, losses from virtual hacks reached $2.5 billion and approximately $1.4 billion in stolen funds resulting from the Bybit hack in the month of February. 

Also, Iranian crypto exchange Nobitex has recently fallen victim of cyber attacks too. It was done by a pro-Israeli hacker group called Gonjeshke Darande. This hack caused a loss of over $81 million, forced to stop services temporarily to mitigate the effect of the breach.
