Code Example: Embedding One-Click Checkout

Here’s a practical snippet for a React-based e-commerce site using OneClickStable. com’s SDK. This code queries the user’s wallet, displays USDC equivalent, and triggers payment with a single button press.

import React, { useState, useEffect } from 'react';
import { OneClickStableSDK } from '@oneclickstable/sdk'; // Replace with actual SDK import path

const CheckoutComponent = () => {
  const [sdk, setSdk] = useState(null);
  const [walletConnected, setWalletConnected] = useState(false);
  const [isLoading, setIsLoading] = useState(false);

  const API_KEY = 'your-api-key-here'; // Replace with your actual API key

  // Initialize SDK on component mount
  useEffect(() => {
    const initSDK = async () => {
      try {
        const sdkInstance = await OneClickStableSDK.init(API_KEY);
        setSdk(sdkInstance);
      } catch (error) {
        console.error('SDK initialization failed:', error);
      }
    };
    initSDK();
  }, []);

  // Detect wallet connection after SDK is ready
  useEffect(() => {
    if (sdk) {
      const checkWallet = async () => {
        const connected = await sdk.detectWallet();
        setWalletConnected(connected);
      };
      checkWallet();
    }
  }, [sdk]);

  // Handle payment: $99.99 equivalent in USDC at $0.9999/USDC
  const handlePay = async () => {
    if (!sdk || !walletConnected) return;

    setIsLoading(true);
    try {
      // Calculate USDC amount: 99.99 / 0.9999 ≈ 100 USDC
      const usdcAmount = 100; // Precise calculation: Math.ceil(99.99 / 0.9999)
      await sdk.pay(usdcAmount, 'USDC');
      console.log('Payment successful!');
    } catch (error) {
      console.error('Payment failed:', error);
    } finally {
      setIsLoading(false);
    }
  };

  return (
    

      
Wallet Connected: {walletConnected ? 'Yes' : 'No'}
      
        {isLoading ? 'Processing...' : 'Pay $99.99 with USDC'}
      
    
  );
};

export default CheckoutComponent;

Adapt this for Vue or vanilla JS; the SDK handles chain abstraction, ensuring compatibility across ecosystems. Post-integration, monitor metrics like approval rates, which often exceed 90% for familiar wallets versus 60% for novel flows.
