This page contains an overview of all standardized Resolver records. The reference is divided into sections, grouping records by their namespaces and use-cases:

• ​Crypto payments​

• ​Browser resolution​

  • ​DWeb records​

  • ​DNS records​

Developers may also set custom records for the domains. Domain records are stored as a key-value dictionary by Resolvers and are not validated on the smart-contract level. For more details, read Architecture Overview and Managing Domain Records.
