Claiming your NFT certificate from the creator is a great way of protecting your purchase and its value.
Go to verisart.com/signup and sign up with the wallet that owns the NFT
If you have an existing Verisart account, you can link your wallet to your account.
Your certificate appears in your dashboard
If your certified NFT is not visible in your dashboard, check you are logged in with the correct Metamask wallet and that the certified NFT is owned by your wallet.
