MEV Bot

Bot script to scan arbitrage opportunities by snipping mempool across multiple DEXs with flash loan and swap feature

Installation

To run the script, the following steps must be followed:

1. Creating the .env file A .env file must be created at the root of the project directory. To do this, you can copy the .env.example file and rename it to .env. The following variables must be filled in with the urls for your node rpc http and websocket endpoints:

HTTPS_URL=...
HTTPS2_URL=...
WSS_URL=...

2. Installing dependencies To install the dependencies, run the following command:

npm install

3. Running the script To run the script, run the following command:

node index.js

The script may take quite some time to run for the first time, as there are not yet any cached data in the data folder.

Setting up the scripts

Assumption: New dev environment, first time running bot on the local machine

You'll need to run the command

node src/tokendumpinfo.js

Currently we haven't specify passing in arguments, so will need to modify the CHUNK_SIZE paramter to be 100 on the first run, then 10, then 1

Then will have to run the command. This script is to eliminate toxic tokens.

node src/patchpooltoken.js.js
cd contracts/forge
forge script ./script/FilterTrapToken.s.sol:FilterTrapToken --rpc-url http://127.0.0.1:8545

---

Then you will deploy the TradeContract. The private key you have in your .env file that has the MATIC used to pay for gas for the trade transaction must also be the owner defined in TradeContract.sol
