Probably, we are talking about a smart contract responsible for the “gasless” deposits of stableclion USD Coin (USDC) and swaps of certain ERC-20 tokens to USDC through API liquidity aggregator 0x. The platform added this feature on November 24, after the incident, access to it was temporarily restricted.
The bug was discovered by a white hacker with the nickname Samczsun. The potential exploit affected 700 addresses containing tokens worth about $ 2 million. As part of the vulnerability remediation procedure, these assets were transferred to an escrow contract address.

Only users who, after November 24, allowed the platform to spend funds from their wallets, were affected. To recover assets from the escrow contract address, you must independently initiate the procedure from the relevant wallet.
Users affected by the incident will see a notification when they go to the platform website. Funds can be recovered at any time.
Am i safe?

The project team promised to publish full information about what happened when the affected users return their funds.
As a reminder, in September, dYdX developers discovered an error in the staking pool smart contract for the DYDX control token.
