Flashbots searcher-minter

This repository contains a very simple demo application of Flashbots, which allows arbitrary submission of a single transaction to Flashbots. This could be used for many simple purposes, but in the demonstration, the goal was to mint an NFT.

How to run

Get some Goerli ETH on a wallet (you'll need a faucet). Extract that Goerli wallet's private key (in MetaMask Account Details -> Export Private Key), use that value below for WALLET_PRIVATE_KEY.

Note: It is EXTREMELY dangerous to deal with private keys in this manner, but bots require access to these keys to function. Be careful when using raw private keys that own mainnet ETH or other valuable assets. Keep as little value in these "hot" accounts as possible.

npm install
WALLET_PRIVATE_KEY=0x1d9af4................ npx ts-node src/index.ts
