Ethereum-Arbitrage-Bot

This codebase improves the simple-arbitrage library for discovering, evaluating and rating arbitrage opportunities on ethereum. It is currently somewhat profitable, but may become progressively less so as the number of users increases. The reason for opening the source code is that I would like to get more suggestions, which would be very helpful!

Environment Variables

• ETHEREUM_RPC_URL - Ethereum RPC endpoint.

• PRIVATE_KEY - Private key for the Ethereum EOA that will be submitting Flashbots Ethereum transactions.

• FLASHBOTS_RELAY_SIGNING_KEY [Optional, default: random] - Flashbots submissions require an Ethereum private key to sign transaction payloads. This newly-created account does not need to hold any funds or correlate to any on-chain activity, it just needs to be used across multiple Flashbots RPC requests to identify requests related to same searcher.

• HEALTHCHECK_URL [Optional] - Health check URL, hit only after successfully submitting a bundle.

• MINER_REWARD_PERCENTAGE [Optional, default 30] - 0 -> 100, what percentage of overall profitability to send to miner. After a month of use, 30 is a relatively balanced value.

• Arbitrage_Amount - The capital used for each arbitrage trade is denominated in WETH. I typically use 0.3 WETH; please adjust this amount according to your specific needs. (WETH does not require advance conversion; it will be automatically converted during arbitrage)

Usage

Make sure you have the node.js environment on your device before you start using it.

1. Clone this repository

git clone  https://github.com/TobiasFeistmantl/Arbitrage-Bot

2. Go to the folder(Can be accessed manually)

cd arbitrage-bot

3. Install project dependencies

npm install

4. Configuring .env parameters

• Go to .env.example and fill in PRIVATE_KEY as the private key of your primary ethereum account in a format that starts with 0x, as in the example.(This wallet requires ETH to cover the fees associated with arbitrage, so please ensure your current environment is secure.)

• BUNDLE_EXECUTOR_ADDRESS is the Ethereum WETH contract address. WETH significantly accelerates transaction speeds during arbitrage, so this parameter should not be modified.

• Create a new Etherwallet for the FLASHBOTS_RELAY_SIGNING_KEY parameter and write the private key to it. (This wallet does not require any funds)

• HEALTHCHECK_URL Can be blank.

• ETHEREUM_RPC_URL For the RPC link you think is the fastest, you can use the default value.

• MINER_REWARD_PERCENTAGE You can use the default value or higher.

• Arbitrage_Amoun The amount of WETH used for arbitrage each time.

When all is done, change .env.example to .env.

5. start running

npm run start
