  • Make sure you are using the same chain and network that your NFT is deployed on.

Issue 2: Incorrect token name in MetaMask import

Symptoms: Token import fails with an “Invalid or not found” error, and the token name does not match what you specified during import.

Causes: You may have entered an incorrect token name or image URI during the import process.

Solution:

  • Check your NFT metadata to make sure it matches the token name in the MetaMask settings.
  • Make sure you are using the correct image URI for the token.
  • Check the image file itself; incorrect images can cause errors.

Issue 3: Invalid Token URI

Symptoms: Importing the contract address fails with an “Invalid or not found” error, and the token name does not match what you specified during import.

Causes: The token URI may be incorrect or missing.

Solution:

  • Check your NFT metadata to make sure it matches the image URI in the MetaMask settings.
  • Verify that the token URI is correctly formatted and accurate.
  • Verify that there are no typos or spelling errors.

Additional tips:

  • Verify the chain ID: Make sure you have updated your wallet settings to match the correct chain ID for your NFT deployment (e.g. Ethereum Mainnet, Ethereum Testnet).
  • Use the correct image URI: Make sure you are using the correct image URI for each token; incorrect images can cause errors.
  • Verify network settings: Make sure that the network settings are configured correctly in MetaMask.

Bottom line:

Ethereum and MetaMask have their own ways of working, and these differences can sometimes cause import issues. By following these steps and checking your wallet settings, you should be able to fix the “ERC-721 NFT” import issue on MetaMask.
