Solana SPL Token Swap Script

This project contains a simple JavaScript script to swap Solana SPL tokens using the Solana Web3.js and SPL Token libraries. The example provided demonstrates swapping SOL with another SPL token.

Prerequisites

Before running the script, ensure you have the following installed:

• Node.js
• npm (comes with Node.js)

Setup

1. Clone the Repository

   git clone https://github.com/your-repo/solana-token-swap.git
   cd solana-token-swap

2. Install Dependencies

   npm install @solana/web3.js @solana/spl-token

Usage

1. Update Constants

   In the script file swap.js, update the mint addresses for the tokens you want to swap if they are different:

   const SOL_MINT_ADDRESS = "So11111111111111111111111111111111111111112";
   const DOGWIFTHAT_MINT_ADDRESS =
     "EKpQGSJtjMFqKZ9KQanSqYXRcF8fBopzLHYxdM65zcjm";

2. Run the Script

   To execute the script, use the following command:

   node swap.js

   The script will:

   • Connect to the Solana mainnet.
   • Generate a new keypair for both the sending and receiving wallets.
   • Request an airdrop of SOL to the sending wallet for testing purposes.
   • Create associated token accounts for both the SOL and the other SPL token.
   • Transfer a small amount of SOL to the receiving wallet.

Notes

• Security: This script uses newly generated keypairs for demonstration purposes. In a real application, you would use securely managed wallets and private keys.
• Error Handling: This script lacks comprehensive error handling. Ensure you implement proper error checking for production use.
• Customization: Modify the token mint addresses, transfer amounts, and other logic as needed for your specific use case.
