IDKit is the new toolkit for identity online. With IDKit you can easily interact with the World ID Protocol.

Integration is very straightforward. Follow the relevant steps below.

yarn add @worldcoin/idkit
# or
npm i @worldcoin/idkit
# or
pnpm install @worldcoin/idkit

import { IDKitWidget } from "@worldcoin/idkit";

<IDKitWidget actionId="get_this_from_the_dev_portal" signal="my_signal" handleVerify={verifyProof}>
  {({ open }) => (
    {/* You can render whatever you want here, and call open() to open the widget */}
    <button onClick={open}>Click me</button>
  )}
</IDKitWidget>

If you are not using React or want to look at additional options (like rendering the component without any children), the useIDKit hook and more, head over to the docs.

import { useIDKit } from "@worldcoin/idkit";

const { open, setOpen } = useIDKit({
	signal: "my_signal",
	handleVerify: verifyProof,
	actionId: "get_this_from_the_dev_portal",
	walletConnectProjectId: "get_this_from_walletconnect_portal",
});

IDKit exposes the handleVerify option for your app to perform additional verification on the returned response, often a call to an API that ensures the proof is valid.

Warning Make sure you verify the proof, and that you don't do it client-side!

Optionally, IDKit also provides an onSuccess option, which you can use if your app needs to execute some code after verification succeeds.

World ID is the privacy-first identity protocol that brings global proof of personhood to the internet. More on World ID in the announcement blog post.

World ID lets you seamlessly integrate authentication into your app that verifies accounts belong to real persons through Sign in with Worldcoin. For additional flexibility and cases where you need extreme privacy, Anonymous Actions lets you verify users in a way that cannot be tracked across verifications.

Follow the Quick Start guide for the easiest way to get started.
