Hi This Version wasn't working for me but I made this version that works for the most recent version of web3 as of 27/11/2025

Extra Tips to Help with a Successful Bot:

• make sure you have USDC.e (contract addy: 0x2791bca1f2de4661ed88a30c99a7a9449aa84174) for the actual trading execution otherwise it will still show balance / allowance error (NOT the other USDC contract addy: 0x3c499c542cef5e3811e1192ce70d8cc03d5c3359)
• had to also test using a higher fill price i.e. 0.55 as opposed to 0.5 (just when testing)
• MOST IMPORTANTLY: build out a redemption system for settlement back into your wallet -> last thing you want is to not be able to claim the money that you won
