Now you will be able to switch the active account in MetaMask back to your vault account, Ledger 3. Once you have that selected, you will be able to refresh the account page of OpenSea, and you should see your NFT! Congratulations, you successfully transferred your first item. Now, let's go ahead and click the three dots on the top left of the NFT, and select hide. With your ledger unlocked, OpenSea will prompt you to sign a transaction. Once you sign the transaction, your NFT will be hidden. Go ahead and go into the hidden NFTs, and you will see it there. Now go ahead and click the three dots and unhide it. Now you will not have to sign any more transactions to hide NFTs in the future. From now on, you will only use this account to receive and store NFTs or tokens, or send them to your buying/selling account. You can hide airdropped NFTs as needed.
