Examples

Example Projects

React

1. Create new Application

Go to the Tweed Management Console and create a new application. This will generate a unique application ID for your application, which you will need to provide to the Tweed SDK. From the console, you can manage the application and modify its settings.

2. Add tweed to your React app

install tweed SDK to your React app.

npm i @paytweed/core-react

3. Integrate Tweed Provider into Your App

Import the Tweed provider from the Tweed React SDK and wrap your application with it. Use the applicationId from the management console.

Add networks

Specify the networks your application will use by passing them to the Tweed provider. Import the Network enum from the React SDK.

App.tsx

import { Network, TweedProvider } from "@paytweed/core-react";
import DemoPage from "pages/demo";

function App() {
  return (
    <>
      <TweedProvider
        applicationId="YOUR_APP_ID"
          options={{
          chains: [Network.POLYGON, Network.ETHEREUM]
          }}
      >
        <HomePage />
      </TweedProvider>
    </>
  );
}

4. Connect the User

Once the Tweed SDK is set up in your application, the first step is to connect the user. Use the connect function from the useAuth hook to display the sign-up/in modal. This allows users to create an account, and a wallet is automatically created for them. You can offer multiple sign-up options; for more details, visit here.

Utilize the loading state from the useTweed hook to manage the loading state, and implement a check to verify that the Tweed client is initialized.

HomePage.tsx

import { useAuth, useTweed } from "@paytweed/core-react";

function HomePage() {
  const { connect } = useAuth()
  const { client, loading } = useTweed();
    
  function handleConnect() {
    if(!client) return
    connect()
  }
  
  return (
    <>
      <h1>HomePage</h1>
      { loading ?
        <h2> loading... </h2> :
       <button onClick={handleConnect}>connect</button> 
       }
    </>
  );
}

export default HomePage;

Token Checkout If you are integrating WaaS for token checkout, you are done at this point and can return to continue the token checkout integration

5. Create Ethereum Provider

With the user logged in and authenticated, we are able to get the Ethereum provider to handle on-chain actions like sending transactions or checking balances.

import useWeb3 hook from tweed SDK

import { useWeb3, Network } from "@paytweed/core-react";

obtain the Ethereum provider

Create a state to hold the provider and a function to obtain it. In this example, we use the useEffect hook to initialize the provider as soon as the user connects, making it available immediately.

const { getEthereumProvider } = useWeb3();

const [provider, setProvider] = useState<BrowserProvider | null>(null);

async function getProvider() {
  const provider = await getEthereumProvider(Network.ETHEREUM_SEPOLIA);
  const web3provider = new BrowserProvider(provider);
  setProvider(web3provider);
}d

useEffect(() => {
  getProvider();
}, [provider]);

HomePage.tsx

import { useAuth, useTweed, useWeb3, Network } from "@paytweed/core-react";
import { BrowserProvider } from "ethers";
import { useState, useEffect } from "react";

function HomePage() {
  const { connect } = useAuth();
  const { client, loading } = useTweed();
  const { getEthereumProvider } = useWeb3();
  
  const [provider, setProvider] = useState<BrowserProvider | null>(null);
  
  async function getProvider() {
    const provider = await getEthereumProvider(Network.ETHEREUM_SEPOLIA);
    const web3provider = new BrowserProvider(provider);
    setProvider(web3provider);
  }
  
  useEffect(() => {
    getProvider();
  }, [provider]);
  
  function handleConnect() {
    if (!client) return;
    connect();
  }
  
  return (
    <>
      <h1>HomePage</h1>
      {loading ? (
        <h2>loading...</h2>
      ) : (
        <button onClick={handleConnect}>connect</button>
      )}
    </>
  );
}

export default HomePage;

6. Test the Integration

Let's create a transaction using the sendTransaction function from ethers.

async function sendTransaction() {
    if (!provider) return;
    const signer = await provider.getSigner();
    const txHash = await signer.sendTransaction({
      to: "0x03928fc2FD91491919F55C8658477fE1352338E7",
      value: "0.1",
    });
    console.log('transaction sent', txHash);
  }

  const { client, loading } = useTweed();
  const { getEthereumProvider } = useWeb3();

  async function getProvider() {
    const provider = await getEthereumProvider(Network.ETHEREUM_SEPOLIA);
    const web3provider = new BrowserProvider(provider);
    setProvider(web3provider);
  }
  
  useEffect(() => {
    getProvider();
  }, [provider]);
  
  function handleConnect() {
    if (!client) return;
    connect();
  }
  
  async function handleSendTransaction() {
    if (!provider) return;
    const signer = await provider.getSigner();
    const txHash = await signer.sendTransaction({
      to: "0x03928fc2FD91491919F55C8658477fE1352338E7",
      value: "0.1",
    });
    console.log('transaction sent', txHash);
  }
  
  return (
    <>
      <h1>HomePage</h1>
      {loading ? (
        <h2>loading...</h2>
      ) : (
      <div>
        <button onClick={handleConnect}>connect</button>
        <button onClick={handleSendTransaction}>send tx.</button>
      </div>
      )}
    </>
  );
}
