An unknown Bored Ape Yacht Membership (BAYC) non-fungible token (NFT) proprietor, referred to as “s27”, not too long ago misplaced roughly $570,000 (roughly Rs. 4.3 crore) value of NFTs after exchanging his BAYC NFT and two Mutant Ape Yacht Membership (MAYC) tokens for fraudulent NFTs deceptively disguised as real. Among the many misplaced NFTs was a “bubble gum ape”. The user claimed to have used an NFT exchange platform named “Swap.Kiwi” for the swap which allows for direct NFT swaps between collectors, reducing transaction fees.
The potentially fraudulent transaction was first spotted by crypto enthusiast who goes by the synonym “quit” (@0xQuit on Twitter), thanks to his Discord server configured to track BAYC and MAYC listings that are at least 5 percent below their floor price in Ether. “The pings are rare, but when they happen it generally means one of two things: somebody is panic selling, or somebody is compromised. When I saw the notification for #1584, I instantly knew it was the latter.”

Quit, who tweeted out his findings in a Twitter thread, discovered that not only did the scammed user transfer his valuable NFTs to a scammer, but he was also the initiator of the trade. Quit went on to track down the scammer’s NFTs that s27 received after the swap was made. All of them appeared as genuine BAYC tokens but actually weren’t.
4/ Further digging showed that he traded on swapkiwi, a trading site similar to NFTtrader or SudoSwap. Furthermore, he *initiated* a trade to lose his apes, which is certainly not normal behavior. I decided to play with KiwiSwap and see how this could’ve happened ????

Quit notes that Swap.Kiwi displays a “green checkmark” to verify that tokens are authentic, but because of the way the checkmark shows up on the UI, it can be easily counterfeited via a simple image editor — and that’s exactly what the scammer did. Essentially, he downloaded some “jpegs” depicting a few expensive BAYC apes and added a fake watermark so that they would appear like the real deal when displayed on Swap.Kiwi.
Shortly after receiving the BAYC and two MAYC NFTs, the scammer sold them for ETH 98.85 (currently around $350,000 or roughly Rs. 2.5 crore), ETH 23 ($81,000 or roughly Rs. 60 lakh), and ETH 25.25 ($90,000 or roughly Rs. 68 lakh) — worth a total of $521,000 (roughly Rs. 4 crore). However, these listings were lower than their corresponding floor prices, placing s27’s potential loss in the ballpark of $570,000 (roughly Rs. 4.3 crore), according to Quit.
