An NFT certificate for domain names is a digital certificate issued for the life of a domain that is used to protect the domain name from fraud. This is a certificate that guarantees the domain owner his exclusive right to own this domain for the duration of the domain name registration. An NFT certificate for domain names works by creating a digital fingerprint on the blockchain network that links the domain name and its owner. This allows you to establish the identity of the owner of the domain name and guarantee his exclusive right to use this name.
