Using Aztec for ENS Privacy

For more details on the scope and description of this proof-of-concept, please refer to the specification. For user manual, see here.

Introduction

This project has been based on the previous ENS privacy research output where a look into possible options has been taken. The goal was to enable users to publish their ENS name, allow people to send crypto to it, without revealing the main address.

Contracts Setup

The contracts are pulled from the ens-contracts and aztec-connect/blockchain repos.

The Aztec contracts are required to deploy locally or on a testnet not supported by aztec. Aztec currently only supports mainnet-fork testnet and there is barely any support to test it out. (Not even a faucet!) The files include:

- interfaces/*.sol
- libraries/*.sol
- AztecTypes.sol
- Decoder.sol
- RollupProcessor.sol

The ONLY modification that is made in these contracts is in RollupProcessor.sol's constructor() where we default the rollupState.paused to be false. (Otherwise, several other intricacies would have to be taken care of.)

For ENS contracts, they are inherently available in ethers.js library, which we are using via hardhat. The contracts that we modified are:

- profiles/*.sol
- ResolverBase.sol
- CustomResolver.sol <- Main contract for our purpose

The CustomResolver currently only supports Address Resolver, but easily extendable to how the default PublicResolver supports other interfaces.

Project Setup

Requirements:

• Node.js (^18.8.0)
• Yarn (^1.22.19)

Install dependencies:

From the project's root directory, run yarn.

Environment vars:

Rename .env.example to .env or create a new .env file and insert your own Alchemy API key and Private key for the account that has some Goerli/Mainnet-fork ETH.

Run tests:

yarn:test

Deployment scripts:

1. yarn deploy:local <- Before running this make sure to run local node using yarn start:node
2. yarn deploy:goerli <- Not necessary. Can use the already deployed contracts, addresses available in .env.example. This will also update the default resolver contract to the deployed CustomResolver contract for the given private key's primary ENS name. You can simply update the resolver address on app.ens.domains instead of running this and updating the new addresses in .env file.
3. yarn deploy:mainnet_fork

Dry Run scripts:

This is mainly to test the setSendPrivate() and sendPrivate() on testnet. Make sure you already have an ENS name registered for the given private key. Set the name in .env.

1. yarn dryRun:goerli
2. yarn dryRun:mainnet_fork
