On March 22, VeVe tweeted that "We have become aware of an exploit of our systems which resulted in a large amount of gems being acquired illegitimately", and that they had closed the market, as well as purchases and transfers of Gems. The market remained closed for over a day as VeVe apparently triaged the problem. It's not clear yet what the impact has been to the platform or its users, though many reported that their NFTs appeared to have plunged in value.
VeVe marketplace goes offline for over a day after an exploit results in a "large amount of gems being acquired illegitimately"
The VeVe marketplace has developed a bit of a reputation as the partner of choice for some big names who have dipped their toes into "licensed digital collectible" NFTs, including Marvel, Pixar, and Coca-Cola. It is also notable for using in-app tokens called Gems, which can be purchased with credit cards, but have been impossible to cash out since the mid-2021 launch (though VeVe has very recently said they are beta testing a cashout system).
