[EP 6.16] [Executable] Enable L2 Reverse Registrars and new .eth registrar controller

Abstract

This proposal enables five chain-specific reverse resolvers for L2 EVM networks, and one default reverse resolver as a fallback mechanism. The five chains are Arbitrum, Base, Linea, OP Mainnet and Scroll.

This proposal also enables a new .eth registrar controller and sets the reverse record of some currently un-named ENS contracts.

Motivation

The current implementation of reverse resolution is limited to Ethereum Mainnet and assumes that every entity (a generic smart contract or user account) has the same address across every EVM chain. This has been falling out of line with reality given the rise in smart contract accounts, indicating that reverse resolution should be resolved via a namespace for each chain, rather than a single reverse namespace for the Ethereum ecosystem at large.

This functionality defined formally in ENSIP-19, combined with ENSIP-11, enables “L2 Primary Names,” meaning developers can build end-to-end ENS experiences without forcing their users to transact on Ethereum Mainnet.

To support optionally setting the default reverse record at registration time, a new .eth registrar controller must also be enabled. Since new controllers have significant overhead, we are also taking advantage of this opportunity to add a referrer field for registrations and renewals. This field is emitted unchanged from the registration and renewal events and allows clients to convey information about the source of a registration or renewal for potential DAO-based referral reward schemes (not defined in this proposal).
