How Metamask gets access to your NFTs
Your NFTs that are on the Ethereum blockchain should automatically appear in your Metamask wallet. When I say appear, I mean the data only should appear, not the actual image. This is because MetaMask browser extension cannot view NFTs. However, you can view them when using Metamask mobile app.
To view NFT tokens via MetaMask mobile:
- Click hamburger menu icon (3 lines).
- Tap Wallet.
- NFTs Tab.
- Import NFTs.
- Paste in the address of the NFT, along with its ID. The address of an NFT is found on your NFT Opensea page, within the details tab. Contact address is what you need to copy.
