We're looking to build an indexer for all ENS records. Loading names is a simple task however determining the proper resolution address presumably requires reading the log events. I have seen AddressChanged emitted in ENS transactions but unsure if this is the correct log to use.
event AddressChanged(bytes32 indexed node, uint coinType, bytes newAddress);
Does anyone have experience with this sort of problem?
The AddressChanged event was introduced in the EIP-2304 standard proposal (currently unfinished - April 2022), extending the original EIP-137 ENS standard with multichain functionality.
So these are two separate events:
AddrChanged introduced in the original EIP-137, emitted when a regular ENS record changesAddressChanged introduced in the EIP-2304 proposal, emitted when a multichain ENS record changesENS docs give a short description of both events: https://docs.ens.domains/contract-api-reference/publicresolver
