This contains monitoring realized NFT trades within the NFT market and evaluating the commerce quantity of the NFT assortment’s ground worth. If the ratio between the 2 commerce values is suspiciously low, it’s going to get flagged as a possible hack.
On the time of writing, the dashboard flagged nearly $25 million price of NFTs hacked by offline signatures. Tal Be’ery, the chief know-how officer of ZenGo, additionally instructed Cointelegraph that one of these hack differs from others in two methods.
