Can an Ethereum NFT contain a URL that takes me to a fake wallet approval page?

Yes. NFT metadata can contain external links, and unsolicited NFTs can be used as bait to direct people to phishing websites. The NFT arriving in a wallet does not itself grant spending permission.

The answer

Yes. NFT metadata can contain external links, and unsolicited NFTs can be used as bait to direct people to phishing websites. The NFT arriving in a wallet does not itself grant spending permission.

What to do next

Do not follow unfamiliar links or sign approvals requested by unexpected NFT metadata; verify the contract and the claimed issuer independently.
