Artemis MEV-Share Uniswap/Sushiswap Arbitrage

This project implements a simple probabilistic UniswapV2/Sushiswap arbitrage on MEV-Share, using the Artemis MEV-Share template found here.

Strategy

Sync

We first load all WETH pools that exist on both Uniswap V2 and Sushiswap for which WETH is token1 in the pair. The list of these pools was found here.

Processing

After loading in the pools, we listen to MEV-Share events for transactions that are made to any of the pools (Uniswap and Sushiswap) loaded in. After detecting such a transaction, we find its corresponding pair (either the Uniswap V2 pair of the Sushiswap pair) and submit backruns of various size.

Directory Structure

The project is structured as a mixed Rust workspace with a Foundry project under contracts/ and typesafe auto-generated bindings to the contracts under bindings/.

├── Cargo.toml
├── bot // <-- Your bot logic
├── contracts // <- The smart contracts + tests using Foundry
├── bindings // <-- Generated bindings to the smart contracts' abis (like Typechain)

Testing

Given the repository contains both Solidity and Rust code, there's 2 different workflows.

Solidity

Forge is using submodules to manage dependencies. Initialize the dependencies:

forge install

If you are in the root directory of the project, run:

forge test --root ./contracts

If you are in in contracts/:

forge test

Rust

cargo test

Generating Rust bindings to the contracts

Rust bindings to the contracts can be generated via forge bind, which requires first building your contracts:

forge bind --bindings-path ./bindings --root ./contracts --crate-name bindings

Any follow-on calls to forge bind will check that the generated bindings match the ones under the build files. If you want to re-generate your bindings, pass the --overwrite flag to your forge bind command.

Installing Foundry

First run the command below to get foundryup, the Foundry toolchain installer:

curl -L https://foundry.paradigm.xyz | bash

Then, in a new terminal session or after reloading your PATH, run it to get the latest forge and cast binaries:

foundryup
