dYdX is a decentralized exchange. Recently it came under attack. This attack is considered to be the v3 platform of this exchange. But recently this decentralized exchange said that the v3 platform of this exchange has revealed the identity of the attacker responsible for the attack. The exchange attack resulted in a loss of $9 million from its insurance fund The decentralized exchange recently said it has upgraded its v3 trading platform to enhance its open-interest monitoring and alerting.
dYdX recently claimed to have identified the person responsible and confirmed that it is now looking at legal action against the person responsible. Even these decentralized exchange authorities are claiming that they are adopting various strategies to protect themselves from future attacks. It even enhanced its v3 trading platform to enhance open-interest monitoring and alerting to avoid future coordinated attacks.
Since the v3 trading platform was vulnerable to attacks due to limitations or vulnerabilities, they are developing the advanced v4 chain specifically to mitigate such risks. This new improved v4 chain has some added benefits. It also has a new feature. The addition of this new feature automatically adjusts the initial margin fraction in response to abnormal changes in price.

dYdX recently shared a tweet about this from former tweeter (X) which I've linked above so you can check it out. It was recently attacked and the attacker used the YFI/USD trading pair across more than 100 wallets for such abuse. Even these attackers initiated many 5x leveraged long positions. That's why the attackers used different addresses. The attacker bought the spot Yearn.finance. When the attackers YFI bought the token which caused its price to increase significantly. YFI is the native token of the Yearn.finance decentralized finance protocol.
Before it was attacked, a week before the YFI incident, the attacker used a similar strategy using SUSHI/USD and at that time they made about $5 million in profit. However, this did not affect the v3 insurance fund. Currently dYdX has increased the initial margin requirement by 100%. What steps today have prevented the attacker from making further gains as a result?
