Quick Start

import { WheelXSDK, QuoteRequest } from '@wheelx/sdk';

const sdk = new WheelXSDK();

const quoteRequest: QuoteRequest = {
from_chain: 1,
to_chain: 1,
from_token: '0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48', // USDC
to_token: '0xdAC17F958D2ee523a2206206994597C13D831ec7', // USDT
from_address: '0x742d35Cc6634C0532925a3b8Dc9F6A7c5D3a7C6a',
to_address: '0x742d35Cc6634C0532925a3b8Dc9F6A7c5D3a7C6a',
amount: 1000000,
slippage: 50,
};

const quote = await sdk.getQuote(quoteRequest);
console.log(`Quote received: ${quote.amount_out} tokens`);
console.log(`Request ID: ${quote.request_id}`);

Browser Usage (MetaMask)

import { WheelXSDK, TransactionExecutor } from '@wheelx/sdk';
import { ethers } from 'ethers';

if (typeof window.ethereum !== 'undefined') {
const provider = new ethers.BrowserProvider(window.ethereum);
await window.ethereum.request({ method: 'eth_requestAccounts' });
const signer = await provider.getSigner();
const sdk = new WheelXSDK();
const executor = new TransactionExecutor(provider, signer);
const fromAddress = await signer.getAddress();

const quote = await sdk.getQuote({ ...quoteRequest, from_address: fromAddress });
const result = await executor.executeQuoteTransaction(quote.tx, fromAddress);
console.log(`Transaction sent: ${result.hash}`);
}
