Solana Jupiter Trading Bot
This is a simple demo uses Jupiter's Metis API and Quicknode's Metis add-on to create a simple Solana trading bot. The bot monitors price differences between token pairs and executes trades when profitable opportunities arise.
概述
This is a simple demo uses Jupiter's Metis API and Quicknode's Metis add-on to create a simple Solana trading bot. The bot monitors price differences between token pairs and executes trades when profitable opportunities arise.
This example is for educational purposes only. Quicknode does not provide financial advice or endorse any trading strategies. Always do your own research and consult with a financial advisor before making any investment decisions.
The demo uses:
- Solana 工具包 (
@solana/kit) - Token program client (
@solana-program/token) - Address Lookup Table client (
@solana-program/address-lookup-table) - Jupiter API TypeScript client (
@jup-ag/api)

入门指南
安装依赖项
Open the project directory:
cd solana/jupiter-bot
Then, install the dependencies:
npm install
# or
pnpm install
# or
bun install
设置环境变量
Make sure you have a Quicknode endpoint handy. You can get one here.
- 重命名
.env.example到.envand update with your Quicknode Solana Node and Metis Add-on Endpoints. - Specify your
SECRET_KEY(the private key of the wallet you want to use for the bot). You can generate a new one withsolana-keygen newcommand using the Solana CLI. - Specify your
SOLANA_ENDPOINT(get one here) andMETIS_ENDPOINT(get one here) or use the public endpoint,https://public.jupiterapi.com.
SECRET_KEY=[00, ..., 00]
SOLANA_ENDPOINT=https://example.solana-mainnet.quiknode.pro/abc123/
METIS_ENDPOINT=https://jupiter-swap-api.quiknode.pro/abc123
Ensure your wallet is funded and modify the trading strategy in bot.ts to suit your needs.
首先，运行开发服务器：
npm run start

How it Works
建筑
- bot.ts # Main bot logic
- index.ts # Entry point
- .env # Environment variables
- package.json # Dependencies
ArbBot Class
The main class that handles all trading logic:
- constructor: Sets up the bot with configuration parameters including RPC endpoints, wallet details, and trading parameters
- init: Initializes the bot by checking wallet balances and starting the price monitoring
- initiatePriceWatch: Creates an interval to regularly check for arbitrage opportunities
- getQuote: Fetches current price quotes from Jupiter Exchange
- evaluateQuoteAndSwap: Analyzes quotes to determine if they meet profit thresholds
- executeSwap: Handles the creation and submission of swap transactions
- refreshBalances: Updates the current SOL and USDC balances
- logSwap: Records successful trades to a JSON file
- updateNextTrade: Prepares for the next trade after a successful swap
- terminateSession: Safely shuts down the bot when conditions require it
- jupiterInstructionToKitInstruction: Converts Jupiter API instruction format to
@solana/kitinstructions - getAddressLookupTableAccounts: Fetches address lookup tables for optimized transactions
- postTransactionProcessing: Handles tasks after a successful transaction
Main Application
A simple runner script that:
- Loads environment variables
- Creates an instance of the ArbBot with configuration
- Initializes and starts the bot
Example Trading Strategy
The bot uses a simple arbitrage strategy:
- Start with an initial token (USDC or SOL)
- Execute a trade when the price exceeds the target threshold
- Update parameters for the reverse trade with a profit margin
- Continue the cycle as long as profitable opportunities exist
