A crypto-wallet is required to perform any NFT/NFTH transaction. There is a basic option for you to create an NFT or Issue benefits to NFT’s without a wallet but you cannot financially benefit from it or undertake any control that requires Owner status. It is therefore recommended a crypto-wallet is opened on one of the mainstream platforms.
The world of crypto is anonymous only in that a wallet address is simply identified by its public key. Everything else is very Public. Every transaction is public, and therefore uncontestable as it is public record (as recorded on a blockchain). Wallet balances are public. Token ownership is public. Transactions are public.
However – when ownership of a wallet needs to be proven there are only a number of ways to do it. The first is to connect your wallet to a DAPP. If you transact on platforms like Opensea.io you will need to connect your wallet first.
That has a couple the drawbacks that you need to always have access to your wallet (connected online) to prove your ownership to a trusted DAPP. An alternative method is to sign a certificate stating that
“I, Joe Bloggs, own wallet 0xffffffffffff”
Copy along with the generated signature only.
using the wallet private key. You then only have to give out the certificate signature (the hash string) along with the certificate for your ownership to be proven without ever having to connect your wallet or give anyone your private key, account password or passphrase. Anyone can check the certificate validity using public information and just the wallet address and signature only – they do not need any other information, private or otherwise. The other advantage of this is that you can then prove ownership of a wallet (and therefore NFTH) if you have photo ID for the name on the cert without even having access to your wallet on you.
NFT Assay Office asks you to generate a certificate when your account is set up so that your ownership can always be verified using the certificate alone from then on.
We recommend MetaMask for a wallet – especially if you need to validate your ownership as it is easy to obtain the wallet public and private keys (some wallets have mnemonic passphrases that need converting into a private key before a wallet certificate of ownership can be signed).
