ENS offchain resolver gateway in Rust
Use the official offchain resolver contract with a Rust gateway instead!
ENS offchain resolver gateway in Rust
Background
Lens and CoinBase announced free ENS domains for their users a few months back. Lens is based on the official offchain resolver contract. The same repository contains a gateway and CloudFlare workers but all of them are implemented in TypeScript (using a TypeScript library for CCIP-Read Server from ChainLink). There isn't any gateway implementation in Rust, nor a CCIP-Read Server library.
Progress
So far two things are available in this repository: https://github.com/jeje/ens-offchain-resolver-gateway-rs
- a gateway working similarly than the TypeScript one
ADatabaseinterface is introduced with an implementation reading a static Json file. - a CCIP-Read Server library in Rust
You can see this gateway in action when requesting https://app.ens.domains/me.jerome-bernard.com on the Goerli network.
Roadmap
- deliver the CCIP-Read Server library in crates.io
- improve documentation
- make it easier to dev custom gateways besides the sample given, probably by introducing a gateway framework as another Rust library
- provide more
Databaseimplementations - Cross Chain Write Deferral Protocol (aka EIP-5559), initiated by CoinBase, is probably worth a look too. It could enable users to edit their records in ENS app instead of requiring a custom app to edit the offchain records.
