IMPORTANT NOTES BEFORE RUNNING THE BOT

  1. The bot uses a wallet address and see phrase - this needs to be the FIRST ACCOUNT (Account0 by default) that was created by default when you installed metamask on your pc / macbook.

    • if this is NOT configured correctly you will get an error that says "(node:45320) UnhandledPromiseRejectionWarning: Error: insufficient funds for intrinsic transaction cost"

  2. Make sure you have the following assets in your MetaMask wallet FOR THE ACCOUNT ADDRESS WITH WHICH YOU ARE USING THE BOT

    • BNB (this is needed for gas)
    • WBNB (this is used to purchase the desired token)
    • IF you want to TEST the bot using WBNB / BUSD, then ADD the BUSD custom token to your MetaMask (0xe9e7cea3dedca5984780bafc599bd69add087d56)
    • Run the bot using the to_Purchase value of the BUSD token contract. This works because liquidity is frequently added to this pool.

  3. APPROVE WBNB in your MetaMask

    • you need to approve your wallet to spend WBNB in order for the bot to be able to make purchases
    • to do this, go to pancakeswap, and in FROM put WBNB, and in the TO put elongate (0x2A9718defF471f3Bb91FA0ECEAB14154F150a385), and click 'Approve'.
    • confirm the transaction in MetaMask
    • Now WBNB should be approved, and the purchase transactions the bot will make on your wallets behalf using WBNB will not fail.

    • the slippage required to purchase the token on pancakeswap on line 15
