Fast facts

• “I lost 70 ETH when I was using the new bidding system of @blur_io,” tweeted pseudonymous NFT trader Keungz, who is also the creator of the Keungz Genesis NFT collection.
• “When a user wants to input 0.1 ETH, if he enters a dot without zero, it becomes 1 ETH,” explained Kuntz, after the bug caused him to accidentally bid 70 ETH on Art Gobbler 8273, which had a floor price of 3.77 ETH.
• Blur replied to the thread saying that its policy is to refund users for platform bugs but not for user errors, adding that the platform will offer a 50% refund in this incident.
• “We originally considered the bid mistake to be a user error because there was no bug in the product per se. After evaluating further, we see how this can be considered a bug from the user’s perspective, so we will refund 50% to traders who were affected by this UI behavior,” wrote Blur, adding that they will offer automatic refunds for “collection bids that were accepted over 25% of the non-flagged floor [price]…”
• Paradigm-backed Blur launched on October 19, branding itself as the “NFT marketplace for pro traders.”
• Art Gobblers is an Ethereum-native collection of 2,319 NFTs created in August, depicting cartoon, animated monsters. The collection had a total trading volume of 11,548 ETH at 06:40 p.m. in Hong Kong.
