A potential exploit or contract issue on SuperRare has resulted in the minting of fraudulent duplicate 1/1 NFTs from artists Matt Kane, Dmitri Cherniak, and OSF. These duplicates are appearing within official collections on OpenSea, leading to deceptive bidding and sales activity in ETH and WETH. Users are advised to exercise extreme caution as the SuperRare contract may be compromised, though osf.eth reports no direct wallet compromise.
