🔧 How to use

First, install the Stylus SDK for Rust and create a new project:

cargo stylus new my-project --minimal

Then, install rustmate:

cargo add rustmate

Import the contracts you want to use:

use rustmate::tokens::erc20::{ERC20, ERC20Params};

👷 How to replicate

Install Python and Rust, and then install the Stylus CLI tool with Cargo:

RUSTFLAGS="-C link-args=-rdynamic" cargo install --force cargo-stylus

Add the wasm32-unknown-unknown build target to your Rust compiler:

rustup target add wasm32-unknown-unknown

Then, clone the repository:

git clone https://github.com/cairoeth/rustmate && cd rustmate

Clone Arbitrum Nitro node that supports Stylus:

git clone -b stylus --recurse-submodules https://github.com/OffchainLabs/nitro-testnode.git && cd nitro-testnode

Run the node and wait for it to start up:

./test-node.bash --init --detach

Open another terminal window and fund the deployer address:

./test-node.bash script send-l2 --to address_0xf39fd6e51aad88f6f4ce6ab8827279cfffb92266 --ethamount 100

Navigate back to rustmate and select a benchmark to run. For example, ERC20:

cd ../benchmark/erc20_benchmark && python snapshot.py

Check the results in the terminal or in the .gas-snapshot file.
