This guide will help you quickly get started with Compound React by walking through a simple example of setting up the provider and using some basic hooks.

​
Basic Setup

First, make sure you have installed Compound React as described in the Installation guide.

​
Setting Up the Provider

To use the hooks provided by Compound React, you need to wrap your application with the CompoundProvider component: 
import React from 'react';
import { CompoundProvider } from 'compound-react';
import { providers } from 'ethers';

function App() {
  // Create an Ethereum provider
  const provider = new providers.Web3Provider(window.ethereum);
  
  return (
    <CompoundProvider provider={provider}>
      <YourApp />
    </CompoundProvider>
  );
}

​
Connecting to a Specific Network

You can specify which network to connect to by passing the network prop to the CompoundProvider: 
<CompoundProvider 
  provider={provider}
  network="base" // Connect to Base network
>
  <YourApp />
</CompoundProvider>

​
Connecting to a Specific Market

You can also specify which market to connect to by passing the market prop: 
<CompoundProvider 
  provider={provider}
  network="base"
  market="usdc" // Connect to the USDC market on Base
>
  <YourApp />
</CompoundProvider>

​
Using Hooks

Once you have set up the provider, you can start using the hooks in your components.

​
Getting Asset Information

To get information about an asset, you can use the useGetAssetInfo hook: 
import { useGetAssetInfo } from 'compound-react';

function AssetInfo() {
  const { data: usdcInfo, isLoading, error } = useGetAssetInfo('USDC');
  
  if (isLoading) return <div>Loading...</div>;
  if (error) return <div>Error: {error.message}</div>;
  
  return (
    <div>
      <h2>USDC Information</h2>
      <p>Symbol: {usdcInfo.symbol}</p>
      <p>Price: ${usdcInfo.price.toFixed(2)}</p>
      <p>Supply APY: {usdcInfo.supplyApy.toFixed(2)}%</p>
      <p>Borrow APY: {usdcInfo.borrowApy.toFixed(2)}%</p>
    </div>
  );
}

​
Getting User Account Information

To get information about the user’s account, you can use the useGetAccountInfo hook: 
import { useGetAccountInfo } from 'compound-react';

function AccountInfo() {
  const { data: accountInfo, isLoading, error } = useGetAccountInfo();
  
  if (isLoading) return <div>Loading...</div>;
  if (error) return <div>Error: {error.message}</div>;
  
  return (
    <div>
      <h2>Account Information</h2>
      <p>Address: {accountInfo.address}</p>
      <p>Collateral Value: ${accountInfo.collateralValue.toFixed(2)}</p>
      <p>Borrow Balance: ${accountInfo.borrowBalance.toFixed(2)}</p>
      <p>Health Factor: {accountInfo.healthFactor.toFixed(2)}</p>
    </div>
  );
}

​
Supplying Collateral

To supply collateral to the protocol, you can use the useSupplyCollateral hook: 
import { useSupplyCollateral } from 'compound-react';

function SupplyCollateral() {
  const { supply, isLoading, error } = useSupplyCollateral();
  
  const handleSupply = async () => {
    try {
      // Supply 100 USDC as collateral
      await supply('USDC', '100');
      alert('Successfully supplied collateral!');
    } catch (err) {
      alert(`Error: ${err.message}`);
    }
  };
  
  return (
    <div>
      <h2>Supply Collateral</h2>
      <button onClick={handleSupply} disabled={isLoading}>
        {isLoading ? 'Supplying...' : 'Supply 100 USDC'}
      </button>
      {error && <p>Error: {error.message}</p>}
    </div>
  );
}

​
Using UI Components

Compound React also provides a set of ready-to-use UI components that work seamlessly with the hooks. These components handle loading states, error handling, and data formatting for you.

​
Basic UI Component Example

Here’s a simple example of using the AssetInfoCard and InterestRateDisplay components: 
import React from 'react';
import { 
  CompoundProvider, 
  AssetInfoCard, 
  InterestRateDisplay 
} from 'compound-react';
import { providers } from 'ethers';

function App() {
  // Create an Ethereum provider
  const provider = new providers.Web3Provider(window.ethereum);
  
  return (
    <CompoundProvider provider={provider} chainId={1}>
      <div className="grid grid-cols-1 md:grid-cols-2 gap-4 p-4">
        <AssetInfoCard assetIndex={0} />
        <InterestRateDisplay />
      </div>
    </CompoundProvider>
  );
}

​
Using the Dashboard Component

For a more comprehensive UI, you can use the CompoundDashboard component which combines multiple components into a tabbed interface: 
import React from 'react';
import { 
  CompoundProvider, 
  CompoundDashboard 
} from 'compound-react';
import { providers } from 'ethers';

function App() {
  // Create an Ethereum provider
  const provider = new providers.Web3Provider(window.ethereum);
  const userAddress = "0x..."; // The user's Ethereum address
  
  return (
    <CompoundProvider provider={provider} chainId={1}>
      <CompoundDashboard 
        userAddress={userAddress}
        baseAssetSymbol="USDC"
        baseAssetDecimals={6}
      />
    </CompoundProvider>
  );
}
The dashboard includes tabs for:
  • Overview (position summary, interest rates, market stats)
  • Supply & Borrow
  • Assets
  • Transaction History

​
Customizing Components

All UI components accept a className prop that allows you to customize their appearance using Tailwind CSS classes: 
<AssetInfoCard 
  assetIndex={0} 
  className="bg-blue-50 border-blue-200 dark:bg-blue-900 dark:border-blue-800"
/>
For more information on customizing the components, see the UI Components section.

Complete Example

Here’s a complete example that combines all of the above: 
import React from 'react';
import { CompoundProvider, useGetAssetInfo, useGetAccountInfo, useSupplyCollateral } from 'compound-react';
import { providers } from 'ethers';

function App() {
  const provider = new providers.Web3Provider(window.ethereum);
  
  return (
    <CompoundProvider provider={provider}>
      <Dashboard />
    </CompoundProvider>
  );
}

function Dashboard() {
  const { data: usdcInfo, isLoading: isLoadingAsset } = useGetAssetInfo('USDC');
  const { data: accountInfo, isLoading: isLoadingAccount } = useGetAccountInfo();
  const { supply, isLoading: isSupplying } = useSupplyCollateral();
  
  const handleSupply = async () => {
    try {
      await supply('USDC', '100');
      alert('Successfully supplied collateral!');
    } catch (err) {
      alert(`Error: ${err.message}`);
    }
  };
  
  if (isLoadingAsset || isLoadingAccount) return <div>Loading...</div>;
  
  return (
    <div>
      <h1>Compound III Dashboard</h1>
      
      <div>
        <h2>USDC Information</h2>
        {usdcInfo && (
          <>
            <p>Symbol: {usdcInfo.symbol}</p>
            <p>Price: ${usdcInfo.price.toFixed(2)}</p>
            <p>Supply APY: {usdcInfo.supplyApy.toFixed(2)}%</p>
            <p>Borrow APY: {usdcInfo.borrowApy.toFixed(2)}%</p>
          </>
        )}
      </div>
      
      <div>
        <h2>Account Information</h2>
        {accountInfo && (
          <>
            <p>Address: {accountInfo.address}</p>
            <p>Collateral Value: ${accountInfo.collateralValue.toFixed(2)}</p>
            <p>Borrow Balance: ${accountInfo.borrowBalance.toFixed(2)}</p>
            <p>Health Factor: {accountInfo.healthFactor.toFixed(2)}</p>
          </>
        )}
      </div>
      
      <div>
        <h2>Supply Collateral</h2>
        <button onClick={handleSupply} disabled={isSupplying}>
          {isSupplying ? 'Supplying...' : 'Supply 100 USDC'}
        </button>
      </div>
    </div>
  );
}

export default App;
