We specialize in rainbowkit integration, crypto wallet connection, rainbowkit react, wagmi, rainbowkit setup, rainbowkit customization, metamask connection, walletconnect, dapp development, web3 wallet, rainbowkit next.js, and connect wallet button solutions. When building a dApp, one of the first challenges is giving users a simple and secure way to connect their wallet. wagmi provides the API, but you still need to write the UI for connecting wallets. RainbowKit delivers a ready-made interface, saving dozens of hours of work (up to 80% time savings). We help customize it for your project—from basic integration to custom themes and headless buttons. We guarantee compatibility with popular networks and wallets. Whether you need rainbowkit next.js integration or a custom connect wallet button, our team has you covered.
RainbowKit Solves the Wallet Connection Problem
Writing your own wallet selection modal, connect button, and state handling takes many hours. RainbowKit eliminates this with a pre-built ConnectButton component that automatically shows balance, avatar, and network switching. Time savings can be up to 80% compared to a custom implementation. MetaMask, WalletConnect, Coinbase Wallet, Rainbow, Trust Wallet—RainbowKit provides a unified UX for all popular wallets. You can even add custom connectors. Built-in themes and an API allow overriding colors, fonts, and border radii. For example, we implemented a custom theme matching the client's brand guidelines in half a day (12 hours). RainbowKit supports mobile browsers and deep linking, which is critical for DeFi applications. RainbowKit has over 5,000 stars on GitHub.
RainbowKit documentation provides detailed setup guides for all frameworks.
Customize the RainbowKit Theme
You can use built-in themes like darkTheme, lightTheme, midnightTheme or create your own using the Theme API. Customize accentColor, borderRadius, fontStack, and overlayBlur. Example configuration:
import { RainbowKitProvider, darkTheme } from '@rainbow-me/rainbowkit';
<RainbowKitProvider
theme={darkTheme({
accentColor: '#6366f1',
accentColorForeground: 'white',
borderRadius: 'medium',
fontStack: 'system',
overlayBlur: 'small',
})}
>
Common Integration Pitfalls
Common mistakes: forgetting to import styles, not setting a projectId for WalletConnect, using getDefaultConfig without specifying chains (only Ethereum shown), failing to wrap the app in QueryClientProvider, and not handling unsupported networks. We check all these scenarios and include them in testing. With over 5 years of experience and more than 20 completed projects (including 3 DeFi platforms and 2 NFT marketplaces), we avoid these pitfalls and deliver without surprises.
Headless Button Case Study
Tech stack: React 18 / Next.js 14 + wagmi v2 + viem + @tanstack/react-query + RainbowKit 1.x. For a DeFi platform, a custom connect button was needed to fit a minimalist design. We used the headless API ConnectButton.Custom to create a button with custom styles and animations. The integration took one day, while all the network switching and balance display functionality remained intact.
Process
- Discovery. Gather requirements: wallet list, networks, design mockups.
- Architecture Planning. Determine architecture: Next.js App Router or Pages Router, method for passing Project ID.
- Implementation. Install dependencies, create
Providers, configure settings. Customize theme to match mockups. - Testing. Verify all scenarios: connect, disconnect, switch network, revoke permissions. Test in browsers and mobile emulators.
- Deployment. Configure production build, CI/CD, error monitoring via Sentry.
Timeline (Approximate)
| Step | Time | Cost |
|---|---|---|
| Basic integration (standard theme) | 1 day | $2,500 |
| Theme customization to match design | 1–2 days | $1,000–$2,000 |
| Headless button and custom UI | 1–2 days | $1,000–$2,000 |
Cost is calculated individually after assessing the scope of work. We guarantee fixed timelines and transparent pricing. Our clients save up to 80% of time compared to custom development. Typical savings range from $5,000 to $15,000. For a typical project, the total investment ranges from $2,500 to $10,000.
Comparison: RainbowKit vs. Custom Implementation
| Criteria | RainbowKit | Custom Implementation |
|---|---|---|
| Development time | 1-3 days | 5-10 days |
| Number of supported wallets | 50+ via WalletConnect | Depends on implementation |
| Customization | Full via theme and headless API | Full, but from scratch |
| Testing | Built-in state handling | Needs writing tests |
| Documentation | Official and community | None |
What's Included
- Integration of RainbowKit, wagmi, viem
- Configuration of wallet list (MetaMask, WalletConnect, Coinbase Wallet, custom)
- Theme customization per design system
- Mobile adaptation
- Documentation on component usage
- Code review and post-deployment support
Common Mistakes and How to Avoid Them
- Forgetting to import styles:
import '@rainbow-me/rainbowkit/styles.css' - Not setting
projectIdfor WalletConnect—modal fails to load - Using
getDefaultConfigwithout specifying chains—only Ethereum appears - Not wrapping the app in
QueryClientProvider - Not handling unsupported network errors—user sees a blank screen
To avoid these, consider ordering a code review during implementation.

Example Custom Wallet Group
import {
injectedWallet,
metaMaskWallet,
rainbowWallet,
walletConnectWallet,
coinbaseWallet,
safeWallet,
} from '@rainbow-me/rainbowkit/wallets';
const config = getDefaultConfig({
wallets: [
{
groupName: 'Popular',
wallets: [metaMaskWallet, rainbowWallet, coinbaseWallet],
},
{
groupName: 'Others',
wallets: [walletConnectWallet, safeWallet, injectedWallet],
},
],
// ...
});
Installation
npm install @rainbow-me/rainbowkit wagmi viem @tanstack/react-query
Minimal Integration
// app/providers.tsx
'use client';
import '@rainbow-me/rainbowkit/styles.css';
import { RainbowKitProvider, getDefaultConfig } from '@rainbow-me/rainbowkit';
import { WagmiProvider } from 'wagmi';
import { mainnet, polygon, arbitrum } from 'wagmi/chains';
import { QueryClient, QueryClientProvider } from '@tanstack/react-query';
const config = getDefaultConfig({
appName: 'MyApp',
projectId: process.env.NEXT_PUBLIC_WC_PROJECT_ID!,
chains: [mainnet, polygon, arbitrum],
});
const queryClient = new QueryClient();
export function Providers({ children }: { children: React.ReactNode }) {
return (
<WagmiProvider config={config}>
<QueryClientProvider client={queryClient}>
<RainbowKitProvider>
{children}
</RainbowKitProvider>
</QueryClientProvider>
</WagmiProvider>
);
}
// Header component
import { ConnectButton } from '@rainbow-me/rainbowkit';
export function Header() {
return (
<header>
<Logo />
<ConnectButton />
</header>
);
}
ConnectButton shows: "Connect Wallet" button if not connected; address + balance + avatar if connected; network switch if unsupported.
Custom Connect Button
import { ConnectButton } from '@rainbow-me/rainbowkit';
export function CustomConnectButton() {
return (
<ConnectButton.Custom>
{(({
account,
chain,
openAccountModal,
openChainModal,
openConnectModal,
authenticationStatus,
mounted,
}) => {
const ready = mounted && authenticationStatus !== 'loading';
const connected = ready && account && chain && authenticationStatus !== 'unauthenticated';
return (
<div {...(!ready && { 'aria-hidden': true, style: { opacity: 0, pointerEvents: 'none' } })}>
{!connected ? (
<button onClick={openConnectModal} className="btn-primary">
Connect Wallet
</button>
) : chain.unsupported ? (
<button onClick={openChainModal} className="btn-danger">
Wrong Network
</button>
) : (
<div className="flex gap-2">
<button onClick={openChainModal} className="btn-ghost flex items-center gap-1">
{chain.hasIcon && (
<img src={chain.iconUrl} alt={chain.name} className="h-4 w-4" />
)}
<span>{chain.name}</span>
</button>
<button onClick={openAccountModal} className="btn-ghost">
{account.displayBalance && `${account.displayBalance} · `}
{account.displayName}
</button>
</div>
)}
</div>
);
})()}
</ConnectButton.Custom>
);
