Domain and subdomain restrictions

• length: 3 - 16 characters, .ada is not included (this is the upper limit for token names length on Cardano)
  • for subdomains: each subdomain level must contain at least 1 character (i.e. .example.ada is not allowed, a.example.ada is allowed)
• allowed characters:
  • lower-case letters: a - z
  • digits: 0 - 9
  • hyphen: - (must not be the first or the last character and must not be repeated consecutively, i.e. example-.ada, -example.ada and exam--ple.ada are all not allowed)
• at most 5 subdomains per domain
• subdomains must not be more than 2 levels deep (i.e. a.b.example.ada or deeper is not allowed)

Warning

If you mint a domain with a large number of characters, you will have less flexibility when it comes to minting subdomains, because the combined total length must not exceed 32 characters.
