Arbitrage BOT using Jupiter API

This is not 100% risk free as transaction may fail but it's a proof of concept to use Jupiter API to do arbitrage on Solana.

This code shows:

  • It checks for USDC => SOL, then SOL => USDC, if output amount in USDC is more than input amount in USDC, then it will trade.
  • It will send a minimum 2 transactions and it may fail but it's fine since transaction fee is cheap on Solana.

example

It shows that it earns 1 cent from the screenshot above:

  • First tx: use 20 USDC to get 0.21213753 SOL
  • Second tx: use 0.21213755 SOL to get 20.01 USDC

It earns less than 1 cent because it uses 0.00000002 SOL but that is insignificant.

How to use?

  1. Install dependencies
pnpm install

  1. Just create a .env file with your PRIVATE_KEY

  2. run the file

node index.mjs
