Quick Start

Get started quickly with TransactionKit

View or fork now on CodeSandbox

The Quick Start below is available as a well documented, fully functioning live example on CodeSandbox.
Otherwise, please keep following the instructions below.

Bootstrap a React App

Let's keep it simple and use create-react-app here. Run the following command in a directory of your choice:
npx create-react-app txkit-quickstart
The above command will install and bootstrap a basic React App into a directory called txkit-quickstart. Once the installation has finished, change directory into your newly bootstrapped React app by typing:
cd txkit-quickstart

Install Transaction Kit

Next, install TransactionKit and Ethers
npm i @etherspot/transaction-kit [email protected]
// or
yarn add @etherspot/transaction-kit [email protected]

Create a Web3 Provider

A Web3 provider ultimately provides access to blockchain account, also known as a wallet.
For the Quick Start example, we will randomly generate a wallet.
index.tsx / index.js
import { EtherspotTransactionKit } from '@etherspot/transaction-kit';
import { ethers } from 'ethers';
// ...
const randomWallet = ethers.Wallet.createRandom();
const providerWallet = new ethers.Wallet(randomWallet.privateKey);

Wrap your <App /> with <EtherspotTransactionKit />

Wrap your React <App /> tag in the <EtherspotTransactionKit /> tag. This will turbocharge your React app with the power of Etherspot and everything that the platform can offer.
index.tsx / index.js
root.render(
<React.StrictMode>
<EtherspotTransactionKit
provider={providerWallet} /* The random wallet we created above */
chainId={80001} /* Polygon Testnet - Mumbai */
>
<App />
</EtherspotTransactionKit>
</React.StrictMode>
);
Get yourself some Polygon Mumbai Testnet funds
In order to execute a transaction, you need to fund your randomly created account with Test MATIC, the native token on Polygon Mumbai. You can get some for free below.

Build a UI

We're going to start with a simple example - sending some MATIC to another address. TransactionKit makes this really, really easy. Have a look at the code below.
import {
EtherspotBatches,
EtherspotBatch,
EtherspotTransaction,
useEtherspotUi,
useEtherspotAddresses,
} from '@etherspot/transaction-kit';
// In your main function body...
const { estimate, send } = useEtherspotTransactions();
const etherspotAddresses = useEtherspotAddresses();
const [address, setAddress] = useState('0x271Ae6E03257264F0F7cb03506b12A027Ec53B31');
const [amount, setAmount] = useState('0.001');
// In your rendering function...
<EtherspotBatches>
<EtherspotBatch>
<EtherspotTransaction
to={address}
value={amount}
>
{/* The following returns a list of Blockchain
addresses that are ready to use */}
{
etherspotAddresses.map((etherspotAddressObject) =>
<div>
<p>Blockchain Name: {etherspotAddressObject.chainName}</p>
<p>Blockchain ID:{etherspotAddressObject.chainId}</p>
<p>Address: {etherspotAddressObject.address}</p>
</div>
)
}
<input
type="text"
value={address}
onChange={(event) => setAddress(event.target.value)}
/>
<input
type="text"
value={amount}
onChange={(event) => setAmount(event.target.value)}
/>
<hr />
<button onClick={() => estimate()}>Estimate</button>
<button onClick={() => send()}>Send</button>
</EtherspotTransaction>
</EtherspotBatch>
</EtherspotBatches>
You must always estimate before sending
Estimating first performs important transaction cost calculations that are required before sending.
Once sent - you can check the transaction on the Polygon Mumbai blockchain explorer here.

🎉
Congratulations!

You've just sent your first transaction using TransactionKit! Wasn't that easy? Why not have a look around the TransactionKit documentation to see what else you can do with TransactionKit!
