# Types of domains

Punk Domains is a modular domain protocol, which means it can support different types of domains with different features and business models.

Currently supported domain types are the following:

• Standard domains:
  • One-time purchase domains
  • Limited set of features
• Flexi domains:
  • One-time purchase domains
  • Many additional features such as custom domain images and metadata, minter role, etc.
• Soulbound domains:
  • One-time purchase domains
  • The same features as Flexi domains
  • Non-transferrable domains
• Renewable domains:
  • Domains with an expiration date
  • Need to be periodically renewed
  • (Still under development)
