Building a Front Running Bot for Pancake Swap on Binance Smart Chain

Introduction

Welcome back to Solidity Repository! In this very special episode, we will be addressing the overwhelming number of requests we have received from viewers and users on how to build a front running bot for trading on Pancake Swap. While this may seem like a daunting task, it can actually be done easily. Today, we will break down the process step by step, enabling you to trade faster and easier on decentralized exchanges. This bot is primarily designed for Pancake Swap on Binance Smart Chain but can also be configured for Ethereum.

What is a Front Running Bot?

A front running bot allows us to sniff the mempool, which is a pool of pending transactions, and inject our own transaction with a higher gas fee before the victim transaction gets processed. By doing this, we can ensure that our transaction is processed first, allowing us to make a profit on the slippage difference. This passive income opportunity is not widely shared, but as a retail trader, I believe that everyone deserves an equal chance.

Step by Step Guide

Follow along with these steps to build your own front running bot for Pancake Swap on Binance Smart Chain.

1. Open up your internet browser (e.g., Google Chrome).
2. Add the Binance Smart Chain Network to your MetaMask wallet by entering the Binance Smart Chain RPC URL and Chain ID.
3. Go to 'remix.ethereum.org', which is an application developed to develop, compile, launch, and transact with smart contracts on the Binance Smart Chain using the Solidity language.
4. Connect your MetaMask wallet to Remix by clicking the green button.
5. Create a new file in Remix by clicking the button on the left side of the screen and saving it with a .sol extension.
6. Copy the front runner bot contract code from the provided link and paste it into the newly created file.
7. Compile the contract using the Solidity compiler in Remix, selecting the correct version.
8. Launch the contract by selecting 'Injected Web3' and clicking 'Deploy'. Ensure that your MetaMask account is connected.
9. Fund your contract with BNB to enable sniping liquidity pools.
10. Start the bot by using the 'create' action in the contract.

Additional Information

• The front runner bot contract provided in this article is coded in Solidity version 0.6.6.
• It does not require any downloads or executable files, making it more trustworthy than paid services offering similar bots.
• The contract scans for the token 'rap BNB' in the mempool. You can verify the address on 'bscscan.com' to ensure its authenticity.
• The bot uses the gas price of the victim transaction and adds one wei to front run it.
• The contract also includes additional functions for handling transactions and gas prices.

Sniffing the Mempool: A Guide to Front Running Transactions

Introduction

In the world of cryptocurrency trading, front running transactions can be a lucrative strategy for savvy traders. Front running involves monitoring the mempool for liquidity pairs and executing trades before others can, allowing traders to capitalize on price discrepancies. In this guide, we will explore the process of sniffing the mempool and funding a contract with BNB to snipe liquidity pools.

Funding the Contract

To begin front running transactions, the first step is to fund the contract with BNB. The more BNB you invest, the larger the transactions you will be able to front run and the higher your potential profits. It is recommended to invest as much as possible, taking into consideration the risk involved. It’s important to note that while front running can be highly profitable, it is not without risks.

Setting Up the Contract

Once the contract is funded, it will automatically send 90% of the profits made from sniped contracts back to your wallet address, while keeping 10% within the token liquidity pool to continue sniffing for new contracts. This setup ensures a continuous cycle of front running opportunities. It is advisable to start with a conservative approach, allowing the bot to use only a portion of the funded BNB at a time.

Funding the Contract with BNB

To fund the contract, follow these steps:

1. Copy the contract address by clicking on it.
2. Open your MetaMask wallet and navigate to the address input field.
3. Paste the copied contract address.
4. Specify the amount of BNB you want to fund the contract with. Remember, the more you invest, the higher your potential returns.
5. Complete the transaction by clicking the "Send" button.

Monitoring the Contract

Once the contract is funded, it is essential to monitor its activity. You can easily view the transaction details on BSCScan.com by clicking the provided link. Be patient, as it may take a few minutes for the bot to start sniffing the mempools and identifying profitable front running opportunities.

Action and Returns

To initiate the front running process, click the "Action" button. This will charge a small gas fee. The bot will begin executing trades and front running transactions. It is important to note that the returns may vary, depending on factors such as the amount of BNB invested and market conditions. While there is potential for significant profits, there is also the possibility of losses. Therefore, it is advisable to thoroughly understand and assess the risks involved.

Repeat the Process

The front running strategy can be repeated as many times as desired. You can continually feed the contract with more BNB to increase your chances of identifying and capturing profitable front running opportunities. However, always exercise caution and assess the risks associated with each new contract that the bot snipes.

Reviewing Returns andBy following the step by step guide provided in this article, you can now build your own front running bot for pancake swap on binance smart chain. remember to fund your contract with bnb to enable it to snipe liquidity pools effectively. this bot can be a great tool for trading and potentially earning passive income. stay tuned for our upcoming video on using the bot on ethereum.

Periodically review your returns to assess the profitability of the front running strategy. It is not uncommon to make significant profits using this technique, but there are no guarantees. Some weeks may yield more substantial returns, while others may be less profitable. The key is to approach front running with a balanced mindset and make informed decisions. Remember, investing more BNB increases the potential for higher returns but also exposes you to greater risks.

In conclusion, front running transactions using the mempool can be an effective strategy for cryptocurrency traders. By following the steps outlined in this guide, you can start exploring the exciting world of front running and potentially reap significant rewards. However, always exercise caution, perform thorough research, and assess the risks involved before engaging in such trading strategies. Happy trading!
