You cannot use the MetaMask mobile app to transfer your NFT GO wallet, since OpenSea only works with the MetaMask browser plugin, not the MetaMask app.
You must have the MetaMask browser extension installed on your computer. If you use the mobile app it will not work.
Transferring NFTs that you minted or bought on NFT GO is very simple. To do this, you simply have to import your NFT GO wallet into MetaMask.
Step 1: Go to the menu tab on NFT GO and select Wallet Private Keys
Step 2: You will see a popup that allows you to copy your wallet’s private key, 12 word passphrase, and address. You must select “Copy Private Key”
Step 3: Go to your MetaMask chrome extension on your desktop browser, NOT the mobile app. Click your account icon in the top right corner. If you do not have the MetaMask browser extension, you can download it here:
Step 4: Select Import Account
Step 5: Paste in your NFT GO Private Key and click Import.
Congratulations, you have successfully imported your entire NFT GO wallet into MetaMask. You cannot see your NFTs visually on MetaMask, however, even though the account is imported. To see your NFTs visually, you need to connect to OpenSea using this MetaMask
Step 6: On your desktop, go to opensea.io and click the wallet icon on the top right corner, then select MetaMask
Step 7: If this is the first time connecting to OpenSea with this wallet, click the MetaMask icon in your browser and confirm that the address you are trying to sign in with is your NFT GO wallet address. MetaMask may ask you to Confirm the sign in.
Step 8: Once you’re logged into OpenSea with your MetaMask, you can go to the Created tab to see your NFTs. From OpenSea, you can transfer NFTs and list them for sale.
During setup, we’ll ask you if you’d like to create a new wallet or import an existing one. If you want NFT GO to create you a new wallet, select “Create Wallet”. You will be shown this page, with your wallet details.
It is essential to write down the 12-word secret passphrase and keep it somewhere safe. This is the key for your wallet, and if you lose it, we cannot retrieve it for you, as we do not store it on our servers. Do NOT share this phrase with anyone. NFT GO will never ask you for this phrase.
You can find your wallet information, such as your wallet address, private key, and 12-word secret passphrase in the My NFTs page. Your wallet address is directly visible under your name, and you can copy it to your phone’s clipboard by tapping the light blue border.
You can find your Private Key and 12-word passphrase by tapping the menu button in the top left of the My NFTs page. Please note: if you created the wallet on NFT GO, you’ll be able to copy the Private Key and 12-word passphrase of your wallet.
However, if you imported your wallet from another source, such as MetaMask, you will be able to copy the Private Key and 12-word passphrase only if you initially imported using the 12-word passphrase. If you imported your wallet using the private key, you will not have access to the 12-word passphrase, only the Private Key. You can find the 12-word passphrase from the original provider, such as MetaMask.
Currently, NFT GO only supports only one connected wallet. You cannot change wallets without deleting and reinstalling the app. However, if you choose to delete and reinstall the app, please ensure you have your current wallet’s 12-word passphrase and Private Keys securely stored, so you can still access your current NFTs. If you do not save the 12-word passphrase of your current wallet, deleting and reinstalling the app will lose your access to the NFTs in your current wallet.
