StakeKit Widget

StakeKit Widget is a component that you can embed in your website with few lines of code. It allows your users to stake their crypto assets and earn rewards.

StakeKit Widget is mainly built as a React component and can be easily added in your application by importing it. There is also an option to use fully bundled widget component which can be added in any javascript library. If your application is already using React, using it as a React component will reduce bundle size of your application. If not, there is option for fully bundled component.

Development

Create .env.development.local file and add variables from .env.example. For production builds, add .env.production.local file

Installation

To install StakeKit Widget:

npm install @stakekit/widget

yarn add @stakekit/widget

pnpm add @stakekit/widget

If you are going to use StakeKit Widget as a React component, you'll need to install some additional peer dependencies:

npm install wagmi@2 viem@2

yarn add wagmi@2 viem@2

pnpm add wagmi@2 viem@2

If you're using Next.js, add this to your webpack configuration in next.config.js:

const nextConfig = {
  webpack: (config) => {
    config.externals.push("pino-pretty", "lokijs", "encoding");

    return config;
  },
};

Usage

To use StakeKit Widget, first you'll need API key from StakeKit.

React component usage

After you get the API key, you can import styles and widget component:

import "@stakekit/widget/package/css";
import { SKApp, darkTheme } from "@stakekit/widget";

const App = () => {
  return <SKApp apiKey="your-api-key" theme={darkTheme} />;
};

Bundled component usage

import "@stakekit/widget/bundle/css";
import { renderSKWidget, lightTheme } from "@stakekit/widget/bundle";

renderSKWidget({
  container: document.getElementById("sk_widget_container")!,
  apiKey: "your-api-key",
  theme: lightTheme,
});

Params

To open the widget on a specific yield opportunity you need to pass the parameter yieldId as a prop to the component. Below is are examples that will open the widget on theethereum-eth-lido-staking. All possible yieldIds can be retrieved from the /v1/stake/opportunities endpoint

React component

import "@stakekit/widget/package/css";
import { SKApp, darkTheme } from "@stakekit/widget";

const App = () => {
  return (
    <SKApp
      apiKey="your-api-key"
      theme={darkTheme}
      yieldId="ethereum-eth-lido-staking"
    />
  );
};

After this is done, you can start using the widget.

Style customization

You can customize look of widget by overriding darkTheme or lightTheme, or providing your own theme and passing it to StakeKit. If theme is not provided, widget will use default lightTheme.

import "@stakekit/widget/package/css";
import { SKApp } from "@stakekit/widget";

const App = () => {
  return (
    <SKApp
      apiKey="your-api-key"
      theme={{
        lightMode: {
          font: { body: '"IBM Plex Mono", monospace' },
          color: {
            primaryButtonBackground: "#8323fd",
            primaryButtonActiveOutline: "#8323fd",
            primaryButtonOutline: "#8323fd",
          },
          borderRadius: { primaryButton: "0", widgetBorderRadius: "10px" },
        },
      }}
    />
  );
};

import "@stakekit/widget/package/css";
import { SKApp, darkTheme } from "@stakekit/widget";

const App = () => {
  return (
    <SKApp
      apiKey="your-api-key"
      theme={{
        ...darkTheme,
        borderRadius: { ...darkTheme.borderRadius, widgetBorderRadius: "10px" },
      }}
    />
  );
};

You can also provide both themes, and widget will respect preference if a user has requested light or dark color themes

import "@stakekit/widget/package/css";
import { SKApp, darkTheme, lightTheme } from "@stakekit/widget";

const App = () => {
  return (
    <SKApp
      apiKey="your-api-key"
      theme={{
        lightMode: lightTheme,
        darkMode: darkTheme,
      }}
    />
  );
};

Tracking

StakeKit component provides tracking prop for analytics to track user actions and page views

import "@stakekit/widget/package/css";
import { SKApp, darkTheme, lightTheme } from "@stakekit/widget";

const App = () => {
  return (
    <SKApp
      apiKey="your-api-key"
      theme={{ darkMode: darkTheme }}
      tracking={{
        trackEvent: (event, props) => {
          console.log(event, props);
        },
        trackPageView: (event, props) => {
          console.log(event, props);
        },
      }}
    />
  );
};

React Native wallets usage

To use StakeKit with your wallets managed provider, you can use utility hook to get prepared props and pass them to WebView component from react-native-webview. Using widget with injected provider skips connection step.

First, install package:

npm install @stakekit/use-inject-provider

or

yarn add @stakekit/use-inject-provider

or

pnpm add @stakekit/use-inject-provider

After that, pass wallets managed EIP-1193 provider and web-views ref to useInjectProvider, and you'll receive injectedJavaScript and onMessage props that you need to pass to WebView component.

Example:

import React, { useRef } from "react";
import { StyleSheet } from "react-native";
import WebView from "react-native-webview";
import { useInjectProvider } from "@stakekit/use-inject-provider";

// Some EIP1193Provider thats managed by wallet
class Provider {
  async request(args) {
    switch (args.method) {
      case "eth_accounts":
      case "eth_requestAccounts": {
        // get accounts from your wallet
        // ...
        return ["0xe455036e2f3a26df7014b7dbf6cedbbf81433478"];
      }

      case "eth_chainId": {
        // get current chain id
        return "1";
      }

      case "eth_sendTransaction": {
        // send transaction and return transaction hash
        // ...
        return "some_transaction_hash";
      }

      default:
        throw new Error("unhandled method");
    }
  }
}

const provider = new Provider();

export const WebViewStake = () => {
  const webViewRef = useRef<WebView>(null);

  const { injectedJavaScript, onMessage } = useInjectProvider({
    webViewRef,
    provider,
  });

  return (
    <WebView
      ref={webViewRef}
      source={{ uri: `${WIDGET_URL}/?api_key=${YOUR_API_KEY}` }}
      onMessage={onMessage}
      injectedJavaScript={injectedJavaScript}
      style={styles.container}
      cacheEnabled={false}
    />
  );
};

const styles = StyleSheet.create({
  container: { flex: 1 },
});
