NFTs in three sentences:
The most common NFT standard on Ethereum is ERC-721, and each NFT is identified by a unique tokenId.
If the metadata and image are stored on a centralized server, the token will still exist after the server shuts down, but the content may become inaccessible.
Before collecting an NFT, check the collection’s contract address. Many collections have the same name, so don’t judge by the name and image alone.
