Description

Description
Chainlink has data feeds in several EVM-compatible chains(Ethereum, BNB, Matic..Etc). However the resolver is only configured for mainnet and hence, ENS cannot be used for other chains. The lookup here works only for mainnet.

Motivation
Make developer experience better on other EVM-compatible chains by allowing them to use ENS to lookup the data feeds.

Additional Information
While reading blogs from the ENS team, I understand that their recommendations are to :

  • only use mainnet for resolution: Our recommendation is simple: always refer to the ENS name on Ethereum mainnet (networkId 1). source
  • set one address for each side chain when registering the ENS records. there is a field called Coin Type source

Research direction

Start with the ENS architecture and lookup documentation linked in the issue, then read the ENS team's multi-chain guidance about mainnet resolution and Coin Type records. No source file or test is identified, so first map where the resolver and data-feed lookup are implemented. Done means defining and implementing support for feed lookups across the intended non-mainnet EVM chains.
