In a decisive move to bolster its trading platform’s stability and security, decentralized crypto exchange dYdX has implemented significant changes in its trading policies. This strategic shift, which includes increasing margin requirements on less liquid markets, follows a major trading incident resulting in the liquidation of positions worth nearly $38 million. dYdX used $9 million from its insurance fund to cover users' losses, mainly targeting YFI token long positions. Additionally, the exchange has now banned "highly profitable trading strategies" to prevent similar future attacks. These measures are a direct response to recent vulnerabilities and signify an important step in fortifying the exchange against market manipulations.
