Custom AA on zkSync

Purpose

Experiment the support for Account abstraction on zkSync (v2, Era).

Initial:

1. Create a factory contract for deploying AAccounts
2. Create a MultiSig 2:2 owned by the 2 AAccount owners
3. Use the AAMultiSig contract to deploy another Account
4. Apply the UUPS proxy pattern to the MultiSig contract

Features

Installation and compilation

You need Node.js and Yarn.

Install all dependencies with pnpm install or yarn.

Compile all contracts with yarn hardhat compile

Deployment and usage

To run the scripts to deploy and execute the contracts, use the zksync-deploy command:

• yarn hardhat deploy-zksync --script deploy-factory.ts: deploys the factory contract
• yarn hardhat deploy-zksync --script deploy-multisig.ts: deploys a multisig wallet and executes a transaction.
