Smart Contracts

The Ethereum Name Service is made up of a set of smart contracts. These smart contracts are responsible for storing and managing information associated with names.

Resolution

The resolution process outlines how a name is resolved. This includes the process of finding a resolver, and then using that resolver to fetch information about a name.

Resolvers

Every name has a resolver, responsible for fetching information about a name, such as address, avatar, and more. Resolvers allow for programmatic control over the information associated with a name, implemented in solidity.

For ENSv2, use or extend the Permissioned Resolver. The ENSv1 Public Resolver remains a reference for unmigrated names. You can also write your own resolver.

ENSv1 Contracts

These pages document the legacy contracts. New .eth registrations use the ENSv2 ETH Registrar.
