OpenSea Mistakes continue to cause Harm for users

While OpenSea remains the world’s largest NFT marketplace, website mistakes and glitches continue to cost users more each day. In one situation, a user reported losing their NFT due to advice given by OpenSea.

Trader and artist swolfchin.eth stated on social media that the marketplace asked its users to cancel all listings off their NFTs. It was mentioned that their NFTs could be sold if their older listing was still active. Following these instructions, the user canceled the listing and discovered that their 15 ETH worth of MAYC Bored Ape NFT ($36,000) was sold for 6 ETH (~ $15,000)

The incident occurred when the cancellation of an older listing for 6 ETH was found by an exploiter that managed to conduct the sale before the cancellation was completed.

Another NFT collector weighed in on Twitter stating that:

“Well, checking the mempool is much easier than scraping all the Opensea APIs to find old orders, since the cancellation tx submitted has all the order details in the tx input data. You are basically handing out your NFT listing details on a silver platter to be frontrun”

He further explained that users can prevent such scenarios by canceling the correct way.

“Make sure you transfer all the NFTs with “inactive Opensea listings” OUT of your address first before canceling the live listings in your original address. Only after all the listings are canceled are you safe to transfer it back.”

Although OpenSea has reimbursed the wronged user, this marks another situation wherein a mistake on their end left its members outraged and vulnerable to cyber-attacks.
