Matcha Meta: The SwapNet security incident does not involve the 0x core contract, and the direct limit setting feature for aggregators has been removed

Matcha Meta posted on the X platform that it has noticed a security incident related to SwapNet, and some users who have disabled "One-Time Approval" on Matcha Meta may be affected.

Currently, we have contacted the SwapNet team, which has temporarily disabled its contract. After reviewing with the 0x protocol team, it has been confirmed that this incident does not involve the core contracts of 0x's AllowanceHolder or Settler. Users interacting with Matcha Meta through one-time approval can use it safely. To prevent similar situations from occurring again, the feature allowing users to set limits directly with the aggregator has been removed.

According to previous news from ChainCatcher, SwapNet was attacked, resulting in approximately $16.8 million in cryptocurrency assets being stolen.
