After some back-and-forth, with legitimate-looking contracts and falsified emails appearing to come from the real company's real founding director, the NFT collector was asked to use their crypto wallet to sign a contract, via the fake company partner website that had been set up.
When the collector did so, the smart contract drained the collector's wallet of its fourteen pricey Bored Ape NFTs, then accepted the highest offers that were outstanding on each of the Bored Apes, netting 852.9 ETH. The scammer converted the stolen ETH to the DAI stablecoin, making off with $1,075,000 in DAI.
