Get Started
Fortmatic SDK allows you to easily integrate your app with the Ethereum blockchain, whether you already have a dApp integrated with web3 or are starting from scratch. Fortmatic provides a smooth and delightful experience for both you and your app's users.
This documentation for the Fortmatic Javascript SDK will get you started in minutes!
Let's start by building a simple Ethereum wallet dApp that uses Fortmatic to send test Ether transactions to other users.
Install Fortmatic SDK to your dApp by including a script tag between the "TODO" comment lines on the CodePen editor.
<!-- TODO: Step 1: Include Fortmatic SDK Script -->
<script src="https://cdn.jsdelivr.net/npm/fortmatic@latest/dist/fortmatic.js"></script>
<!-- End Step 1 -->
$ npm i --save fortmatic@latest
Create a Fortmatic instance with your API key with the following script and replace your existing web3 provider.
Make sure to use your Testnet key for this tutorial.
// TODO: Step 2: Setup Developer API Key
// You must specify the testnet chain
let fm = new Fortmatic('YOUR_TEST_API_KEY', 'goerli');
web3 = new Web3(fm.getProvider());
// End Step 2
You can implement web3 functionalities just like how you would normally with MetaMask.
// TODO: Step 3: Send Transaction Implementation
web3.eth.sendTransaction({
// From address will automatically be replaced by the address of current user
from: '0x0000000000000000000000000000000000000000',
to: address,
value: web3.utils.toWei(amount, 'ether')
});
// End Step 3
After putting the 3 code snippets above into the editor, click on the Send Transaction button in the web preview and voilà! Your app is now blockchain enabled!
