dYdX raises margin requirements in some markets, bans “highly profitable trades”
cointelegraph.comDecentralized crypto exchange dYdX has disclosed new measures to mitigate trading-related risks after burning $9 million of its insurance fund on Nov. 17 to cover users’ losses.
According to an announcement on X (formerly Twitter), the exchange increased margin requirements on several “less liquid markets,” affecting tokens such as Eos (EOS), 0x Protocol (ZRX), Aave (AAVE), Algorand (ALGO), Internet Computer (ICP), Monero (XRM), Tezos (XTZ), Zcash (ZEC), SushiSwap (SUSHI), THORChain (RUNE), Synthetix (SNX), Enjin (ENJ), 1inch Network (1INCH), Celo (CELO), Yearn.finance (YFI), and Uma (UMA).
dYdX triggered its insurance fund to cover users’ trading losses on Nov. 17 after a profitable trade targeting long positions on the YFI token caused the liquidation of positions worth nearly $38 million.
dYdX founder Antonio Juliano dubbed the move a "targeted attack" on the exchange. According to him, YFI's open interest in dYdX spiked from $0.8 million to $67 million in a matter of days as a result of the actions of one individual. The same individual, according to Juliano, attempted to attack the SUSHI market on dYdX a few weeks earlier.
"We did take action to increase initial margin ratios for $YFI prior to the price crash, but this was ultimately not sufficient. The actor was able to withdraw a good amount of $USDC from dYdX right before the price crash," he wrote.
On X, the exchange’s team said that "highly profitable trading strategies have now been banned on dYdX,” in a reference to the language used by Mango Markets’ exploiter Avraham Eisenberg in his $116 million attack of 2022.
