Why Developers Love ArcPay

❌ Traditional Way
// 150+ lines of code
import { ethers } from 'ethers';
import { Circle } from '@circle-fin/...';
import { x402 } from 'x402';

const provider = new ethers.Provider(...);
const signer = provider.getSigner();
const contract = new ethers.Contract(...);
await contract.approve(...);
await contract.transfer(...);
// ... 140 more lines
✅ With ArcPay
// Voice command
await agent.executeVoice();
// "Send 50 to writer-bot"

// Or one line
await pay('0x...', '50');

// Or with image
await agent.payInvoice(img);

// That's it! 🎉
