3,832 NFTs worth more than $1.5M just moved for Zero ( 0 ) $ETH

At first glance, it looked like a massive Magic Eden exploit.

A wallet later claimed the NFTs were rescued by a whitehat because old Ethereum approvals had left them vulnerable, and that the assets would be returned once the risk is gone.

Magic Eden hasn't confirmed an exploit or officially confirmed the whitehat operation yet.

But there's already a useful lesson here:

Old approvals don't magically disappear just because you stopped using a platform.

If you've ever traded NFTs through Magic Eden on Ethereum, it's worth checking your old approvals and revoking anything you no longer need.
