Use the ENS Universal Resolver (0xeEeEEEeE14D718C2B47D9923Deab1335E144EeEe) as the sole resolution path for all read operations. Per ENS docs, the UR is "the canonical entrypoint to ENS for name resolution." This fixes ENSv2 readiness by: - Eliminating the supportsInterface gate that blocked CCIP-Read/offchain resolution - Supporting DNS name resolution and cross-chain (L2) address lookups - Reducing RPC round-trips (single UR call vs registry→resolver→call) Deleted legacy code: _get_resolver, _resolve_legacy, _resolver_supports_interface, _validate_resolver_and_interface_id, _type_aware_resolver, UnsupportedFunction. Write operations unchanged — still use the registry directly. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Hey! I'm Dhaiwat from the DevRel team at ENS Labs. We're working on getting libraries across the ecosystem ready for ENSv2.
What was wrong?
ENS read operations (
address,name,get_text,resolver) query the ENS Registry directly instead of using the Universal Resolver. The Universal Resolver (0xeEeEEEeE14D718C2B47D9923Deab1335E144EeEe) is the canonical entry point for ENS resolution on Ethereum Mainnet and is required for ENSv2 readiness. Once ENSv2 is live, libraries that don't use the Universal Resolver will resolve some names to incorrect or stale addresses.How was it fixed?
Updated all ENS read operations to use the Universal Resolver instead of querying the ENS Registry directly. Write operations (
setup_address,setup_name,set_text) are unchanged.UNIVERSAL_RESOLVER_ADDRconstantUNIVERSAL_RESOLVERABI withresolve(),reverse(), andfindResolver()functions_resolve(),address(),resolver(), andget_text()to call the Universal Resolver_get_resolver,_resolve_legacy,_resolver_supports_interface,_validate_resolver_and_interface_id,_type_aware_resolver)With this PR, web3.py goes from 3/9 to 6/9 on our official resolution-tests suite for libraries:
