Treasure NFT marketplace exploitedHappened on March 3rd, 2022
Around ~$1.4M worth of NFTs has been stolen from the largest NFT marketplace on Arbritrum due to a smart contract bug that allowed listed NFTs to be bought for free due to missing check for non-zero quantity. The fix was simple, to include a check to ensure quantity was greater than 0. Shortly after the bug began to be exploited, the marketplace was paused and transactions started to fail. John Pattern (CoFounder) made a statement shortly after the event stating they aim to make users whole.
