NFT Mint Scam

NFT mint scams ride the hype around a new collection or surprise drop. A link, usually shared on social media or in a Discord or Telegram, leads to a fake mint site or a malicious smart contract. When you connect your wallet and approve the transaction, instead of minting an NFT you may sign away access that lets the attacker drain your tokens or transfer your existing NFTs. The hype and a ticking countdown are designed to make you approve quickly without checking.
