Before you begin, ensure you have met the following requirements:
Deploy a Solana node on Chainstack; the following steps will guide you:
Add your RPC endoint and private key to a .env
file:
RPC_URL=YOUR_RPC_URL
WALLET_PRIVATE_KEY=YOUR_PRIVATE_KEY
Clone the repository locally and install the dependencies:
git clone https://github.com/soos3d/raydium-sdk-swap-example.git
cd raydium-sdk-swap-example
yarn
Edit the configuration in src/swapConfig.ts
editing:
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: "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v", // USDC 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
