min-zksync-create2

This repository demonstrates how to compute and deploy contracts using create2 on ZKsync and compares it to traditional EVM-based chains. It provides tests for deploying smart contracts using create2 on both ZKsync and EVM, allowing you to observe the differences between the two implementations.

Prerequisites

Ensure that you have foundry-zksync installed. Follow the installation instructions in the Foundry-zksync repository.

Getting Started

To get started with this repository, follow the steps below:

1. Clone the repository

git clone git@github.com:dutterbutter/min-zksync-create2.git

Navigate into the project directory:

cd min-zksync-create2

2. Install Dependencies

Install the necessary dependencies using forge:

forge install

3. Build the Project for ZKsync

To build the project for ZKsync, run:

forge build --zksync

You may encounter a compilation error due to a placeholder value in the system contracts library.

4. Fix the Compilation Error

To fix the compilation error, navigate to the Constants.sol file in the era-contracts library and replace the placeholder value with the actual system contract offset value:

File: lib/era-contracts/system-contracts/contracts/Constants.sol:20:44
Change:

uint160 constant SYSTEM_CONTRACTS_OFFSET = {{SYSTEM_CONTRACTS_OFFSET}}; // 2^15

uint160 constant SYSTEM_CONTRACTS_OFFSET = 0x8000; // 2^15

5. Run Tests

After fixing the compilation error, you can run the tests for both zkSync and EVM-based chains to observe the differences.

Running Tests on ZKsync

To run the tests on ZKsync, use the following command:

forge test --match-path test/Create2ZK.t.sol --zksync --enable-eravm-extensions -vvvv

Running Tests on EVM

To run the tests on an EVM-based chain, use the following command:

forge test --match-path test/Create2Test.t.sol -vvv
