SIMPLE SCRIPT TO SWAP TOKEN ON RAYDIUM WITH TYPESCRIPT USING MULTIPLE ADDRESSES

This project demonstrates how to perform a token swap on the Solana blockchain using Raydium and Chainstack.

Features

• Utilizes the Raydium SDK for interacting with the Solana blockchain.
• Supports both versioned and legacy transactions.
• Allows simulation of swap transactions before execution.
• Easy configuration for swap parameters through a dedicated config file.

Prerequisites

Before you begin, ensure you have met the following requirements:

• Node.js installed (v18 or above recommended)
• Yarn
• A Solana wallet with some SOL for testing the swap
• An environment file (.env) with your RPC URL and WALLET_PRIVATE_KEY

Chainstack Solana node

Environment variables

Add your RPC endoint and private key to a .env file:

RPC_URL=YOUR_RPC_URL
WALLET_PRIVATE_KEY=YOUR_PRIVATE_KEY ALL

Installation

Clone the repository locally and install the dependencies:

Usage

Edit the configuration in src/swapConfig.ts editing:

• Select if you want to send the transaction or only simulate
• The amount to swap
• The tokens to swap
• The liquidity file to pull the pool info from

export const swapConfig = {
  executeSwap: false, // Send tx when true, simulate tx when false
  useVersionedTransaction: true,
  tokenAAmount: 0.01, // Swap 0.01 SOL for USDT in this example
  tokenAAddress: "So11111111111111111111111111111111111111112", // Token to swap for the other, SOL in this case
  tokenBAddress: "", // other token address
  maxLamports: 1000000, // Max lamports allowed for fees
  direction: "in" as "in" | "out", // Swap direction: 'in' or 'out'
  liquidityFile: "https://api.raydium.io/v2/sdk/liquidity/mainnet.json",
  maxRetries: 10
};

Then run:

yarn swap
