    I need a script that I can run without a UI using node JS or python to swap 100% of one token for another on the arbitrum network via uniswap using the router contract and having it select the best route for the trade I am using INFURA as my end point. I also need the script to USE the INFURA GAS API ( uses metamask api)and estimate the gas for each transaction and use whatever the amount is for "priority" Before the Trade is executed I need it to first check if the wallet being used has a balance of the token I will be purchasing with. If there are no tokens present then I need it to do nothing. If tokens are present then I need it to execute the swap as stated above.
