AppKit FAQs

This FAQ section covers common questions and solutions for using AppKit. The questions are organized into three main categories:

• Configuration: Questions about setting up AppKit, including project configuration, wallet visibility, and RPC customization.
• Features: Information about AppKit’s capabilities, including off-ramp support, multi-wallet address retrieval, and branding options.
• Technical: Technical details about project approval requirements and initialization constraints.

AppKit Configuration

Why am I seeing an 'Invalid App Configuration' error?

This error typically occurs when the projectId is not configured correctly. To resolve this:

1. Create a valid project ID at https://dashboard.reown.com/
2. Add it to your AppKit configuration:

const modal = createAppKit({
  ...
  projectId: "..." // Add your valid projectId here
});

3. Ensure that you have added your domain to the allowed domains in your project settings. If you have not done so, you can do so by navigating to “Project Domains” on the Dashboard, clicking on “Configure Domains” and adding your domain.

Why can't I see any wallets in the modal and only see the 'Connect Wallet' title?

Problem: Users only see the “Connect Wallet” title in the modal after clicking the connect button.

Solution: This issue typically has two possible causes:

1. Version Mismatch: Ensure all @reown libraries use the same version in your package.json:

{
  "dependencies": {
    "@reown/appkit": "1.7.8",
    "@reown/appkit-adapter-wagmi": "1.7.8"
    // ... other dependencies
  }
}

2. Initialization Location: Call createAppKit outside of your component to ensure proper initialization:

// Create modal
createAppKit({
  adapters: [wagmiAdapter],
  ...generalConfig,
  features: {
    analytics: true // Optional - defaults to your Cloud configuration
  }
})

export function App() {
  return (
    <WagmiProvider ...>
      <QueryClientProvider ...>
        <appkit-button />
      </QueryClientProvider>
    </WagmiProvider>
  )
}

How can I use custom RPCs with AppKit?

You can use your own RPC by setting the customRpcUrls option in the AppKit configuration. This lets you define custom RPC URLs for specific chains. Each entry must follow the format:

customRpcUrls: {
  [ChainId.Ethereum]: 'https://your.custom.rpc.url',
  [ChainId.Polygon]: 'https://your.polygon.rpc.url'
}

AppKit will prioritize these URLs over the default ones.

Features

When will Reown support off-ramp functionality?

Reown currently does not plan to support off-ramp functionality.

How do I get retrieve multiple addresses from multiple connected wallets?

To retrieve addresses from multiple connected wallets, refer to our multichain example:

• Live Demo
• Source Code

Example using React SDK:

import { useAppKitAccount } from '@reown/appkit/react'

// Get account states for different chains
const eip155AccountState = useAppKitAccount({ namespace: 'eip155' })
const solanaAccountState = useAppKitAccount({ namespace: 'solana' })

<>
  EVM Address: {eip155AccountState.address}<br />
  Solana Address: {solanaAccountState.address}<br />
</>

How do I remove the 'UX by Reown' branding?

Currently, only enterprise clients can hide “UX by Reown” on the AppKit modal by adjusting this option on our Dashboard. If you are an enterprise client and would like to hide this branding, please contact [e-mail].

How do I increase my project's RPC limits?

Reown currently provides 2.5 million requests per 30 days. If you wish to increase this limit, you need to upgrade to AppKit Pro.

Technical

Do I need to wait for Web3 app approval before using my projectId?

No, dApps do not need approval in order to use your projectId.

Can I reinitialize AppKit with different network configurations?

Currently, createAppKit can only be called once during the application’s lifecycle. It cannot be lazily initialized and then torn down for re-initialization. This means you must pass in all the networks you plan to support during the initial setup.
