시작하기

의존성 설치

프로젝트 디렉터리를 엽니다:

cd solana/jupiter-bot

그런 다음, 종속성을 설치하세요:

npm install
# or
pnpm install
# or
bun install

Set Environment Variables

Make sure you have a Quicknode endpoint handy. You can get one here.

Rename .env.example ~에 .env and 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 with solana-keygen new command using the Solana CLI.
Specify your SOLANA_ENDPOINT (get one here) and METIS_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.

First, run the development server:

npm run start
# or
pnpm start
# or
bun start

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/kit instructions
getAddressLookupTableAccounts: Fetches address lookup tables for optimized transactions
postTransactionProcessing: Handles tasks after a successful transaction
