From the FAQ on the dots.nothing.tech page:
1: Login your account on dots.nothing.tech.
2: Click the wallet address on the top right corner and click “View wallet info”.
3: Cick “Get your private key” and follow the email verification steps.
4: Copy and save your private key safely.
5: Open metamask or another wallet you prefer, create a wallet and import your private key from dots.nothing.tech.
6: Success. Now you’ve connected the dots.nothing.tech wallet with your Metamask or other preferred wallet. You can view your NFT on more platforms now.
Then you can go to Opensea and connect to Metamask. It’ll be under the hidden category by default (‘More’ and ‘Hidden’ from your profile). And Metamask doesn’t display NFTs very well so don’t be surprised that you can’t see the NFT in Metamask; that’s normal, and it won’t affect the functionality of the NFT at all.
