Solana On-Chain Trading Bot (Very Immature Now)

This project is owned by @handsomevictor, a Chinese boy living in Paris.

Introduction

The aim of this project is to provide a powerful tool for trading on Web3's most renowned exchanges, such as JUP. JUP is primarily used for swapping tokens, and this tool focuses on utilizing it for trading rather than traditional limit orders.

Usage

Before using the project, ensure you have created a wallet, transferred some SOL or other tokens to it, and placed the public and private keys in the environment variables. The project utilizes these keys to sign transactions.

USER_PUBLIC_KEY = os.environ.get("TEST_USER_PUBLIC_KEY")
USER_PRIVATE_KEY = os.environ.get("TEST_SOLANA_USER_PRIVATE_KEY")

How to Run

Execute transaction_executor.py in ./trading_bot.

Example Calculation

Assume your Solana wallet holds 1 SOL and 1 USDC, and you want to swap 0.1 SOL for USDC. Assuming a gas fee of 0.00007 SOL and a price of 1 SOL = 100 USDC, the result would be:

• SOL: 1 - 0.1 (swapping amount in SOL) - 0.00007 (gas fee) = 0.89993
• USDC: 1 + 0.1 (swapping amount in SOL) * 100 (exchange rate) = 2

Email Notification

If you want to use it, register an account on Outlook (or any other email service) and enable the SMTP server, and change the following parameters in ./tools/resources.py or add them to your environment variables:

• SMTP_SERVER
• SMTP_PORT
• SENDER_EMAIL
• EMAIL_PASSWORD

Reminders

• Never trade all your SOL. Always leave some for gas fees.
• No matter if a trade is made or not, as long as it's sent to the blockchain, a gas fee will be charged (range is usually 0.00006 - 0.00015 SOL but can be higher).

Resourcess
