Testnet deployment addresses (Holesky and Sepolia)

🧑‍💻 ENS Development
1

I just deployed the ENS contracts to Holesky. Since Goerli is being deprecated, going forward we will only be deploying testnet contracts to Holesky and Sepolia. I’ve listed the testnet addresses below, but if these break, please check directly in the ens-contracts repo for the latest deployments. You can also check the docs here: Deployments | ENS Docs

Discovery mechanisms

It is recommended to use these discovery mechanisms within your app to avoid using the wrong contract as and when contracts are being upgraded. If you are directly using an address for an upgradeable, expect it to break in the future.

As usual these contracts can be discovered using ENS directly:

  • NameWrapper - ens.resolver(namehash('eth')).interfaceImplementer('0x019a38fe')
  • .eth Registrar Controller - ens.resolver(namehash('eth')).interfaceImplementer('0x612e8c09')
  • BaseRegistrar - ens.owner(namehash('eth'))
  • Reverse Registrar - ens.owner(namehash('addr.reverse'))
  • Public Resolver (mainnet) - ens.resolver(namehash('resolver.ens.eth')).addr()
  • Public Resolver (testnets) - ens.resolver(namehash('resolver.eth')).addr()

Main addresses

Below are the main ENS contracts. If you need some of the internal contracts, you can directly check the ens-contracts repo to see the latest deployments in the deployments folder

@jefflau.eth Thanks for deploying these. Can you take a look at this Sepolia/Holesky - public resolver namehash for "resolver.eth" not set on ENS registry TL:DR ens.resolver(namehash('resolver.eth')).addr() is not set on sepolia/holesky registries

Hi three9s,

Thanks for bringing this up. Unfortunately we didn’t add these to our deploy scripts, so currently on Sepolia resolver.eth is owned by someone else. If the owner does read this, please transfer it to us here: 0x0f32b753afc8abad9ca6fe589f707755f4df2353.

I set resolver.eth on Holesky to the public resolver.

We own resolver.eth on Sepolia. Raffy pinged us today. Fixing this. @artii

Would be good to update the docs with this information: I’m at a hackathon where they asked me about it and the only source of info which was not 3 years old was this forum post:
