Plain-English storyAn NFT is a unique token with a contract address and an ID. It points to metadata (image, traits, links). The token lives on-chain; the image might not. You’ll learn how to tell real from fake and why approvals can drain your wallet.
What you’ll learnHow to verify the real contract, check where the art is stored, read traits on an explorer, and spot scam patterns like lookalike collections, surprise approvals, and free airdrops asking you to “connect and claim.”
Your goalPick an NFT with confidence: confirm it’s the right contract, see where the file lives, understand what approvals you’re granting, and avoid clicking mint links that feel off. MetaMask is our example wallet, but the checks are the same on Rabby or Coinbase Wallet.
