TLD (Top-Level Domain)

A TLD (Top-Level Domain) is the rightmost part of a domain name — .com, .org, .io, .xyz, .de, .uk, and so on. TLDs are administered by registries operating under ICANN contract (for gTLDs and new gTLDs) or under country-level authority (for ccTLDs like .uk or .de). Each TLD has its own rules around eligibility, pricing, renewal, and what a registrar can do with names under it. Different TLDs also vary in how easily they can be tokenized: some TLDs and registries have moved earlier than others toward supporting on-chain ownership layers, others haven't moved at all. The Choosing a Domain Tokenization Platform post discusses how to evaluate TLD coverage across platforms. Reference: ICANN's list of TLDs.
