[Notice] Opensea’s Discount Bug

On Monday, Opensea faced a user interface flaw that enabled three attackers to buy popular NFTs at their older, lower prices. The three buyers of these NFTs gained massive profit through this incident.

Opensea explained that “this is not an exploit or a bug” but rather “an issue that arises because of the nature of the blockchain”. They also told that as a way of preventing this problem from happening in the future, they added a dashboard that shows all of one user’s inactive listings. The users can cancel their old listings in this dashboard.

If you don’t want to suffer any loss, cancel your old listings.

Here’s how:
