Registrant

A registrant is the person or organization that holds the rights to a registered domain — the registered name holder on record. The registrant contracts with a registrar, which in turn works with the registry under ICANN rules; the registrant is the closest thing the traditional system has to an "owner," though those rights live in a registrar account rather than something you hold directly. This is exactly what tokenization changes: when a domain is tokenized, control moves into a wallet as an on-chain ownership layer, so the registrant's rights become a transferable asset you custody yourself rather than a row in a registrar's database.
