The decentralized trade (DEX) GMX has fallen sufferer to an exploit by a big and complicated dealer who reportedly was in a position to “siphon all of the liquidity” from its avalanche (AVAX) market and revenue from the manipulated value.
In keeping with a number of threads posted on Twitter by main members of the crypto neighborhood, the worth of AVAX was manipulated by a big “whale” who first took a multi-million-dollar place in AVAX on GMX, after which manipulated the worth larger on different exchanges.
In keeping with some sources, the dealer made as much as $1m by doing this, whereas others declare the revenue from the market manipulation was solely about half of that.
GMX differs from most different exchanges – each centralized and decentralized – in that it has a particular characteristic that lets customers keep away from slippage, even for giant orders.
In buying and selling, slippage is the distinction between the worth a dealer thinks he’ll get and the one he truly will get when the commerce is executed. On all exchanges, massive orders particularly could cause slippage, as there generally isn’t sufficient liquidity obtainable at the most effective market value to accommodate the complete order. Specifically, this could be a downside for smaller tokens with little buying and selling volumes.
On GMX, the trade guarantees that the spot value in its market is not going to change regardless of how massive of an order is positioned available in the market, thus letting the person keep away from slippage. Consequently, the dealer who exploited the trade was in a position to take a big place in AVAX with out affecting the worth, earlier than then driving up the worth of the identical token on one other trade.

Amongst those that voiced concern was Taureau, the pseudonymous founding father of the competing DEX Zigzag, who in a latest podcast interview mentioned GMX’s no-slippage mannequin “sounds sort of insane.”
“I’m a bit of skeptical that the GMX mannequin can final,” Taureau mentioned within the podcast, referring to a state of affairs the place bigger and extra refined merchants are available to benefit from GMX’s no-slippage system.
The issue with counting on a no-slippage system was additionally pointed to by others, with one Twitter person saying the system opens the trade up for “value manipulation exploits:”
