JavaScript SDK for RevShare Public API - Create bonding curve tokens with distribution features

const { RevShareSDK } = require('../dist/sdk.cjs.js');
const { Keypair } = require('@solana/web3.js');

/**
 * Example demonstrating bonding curve swap functionality
 * 
 * This example shows how to:
 * 1. Build buy transactions for bonding curve tokens (pre-bonding phase)
 * 2. Build sell transactions for bonding curve tokens (pre-bonding phase)
 * 3. Execute bonding curve swaps with automatic signing and sending
 * 
 * Note: These methods are specifically for tokens in the bonding curve phase
 * that have not yet bonded. For regular token swaps after bonding, use different methods.
