You can deposit an NFT into a vault wallet on Coinbase Prime. To confirm if your NFT collection is supported and to deposit your NFT:
In the Portfolio tab, next to the Search icon, search for the NFT collection > select the asset you’d like to deposit.
Next to View Collection, select the Ellipses icon > Deposit.
You’ll be prompted to create an NFT wallet if there’s no existing wallet. This action requires consensus approvals. After it’s created, select Deposit.
Select Deposit from External Address.
Select the Copy icon or click View QR Code to copy the wallet address.
Important: Depositing an unsupported NFT to a vault wallet could result in permanent loss of your asset.
Complete the Send process from your external address to your Coinbase Prime address (you can't initiate a deposit from Coinbase Prime).
You can confirm the deposit from the Activity tab of your portfolio.
