AppKit provides seamless integration with multiple blockchain ecosystems. It supports [Wagmi](https://wagmi.sh/) and [Ethers v6](https://docs.ethers.org/v6/) on Ethereum,
[@solana/web3.js](https://solana-labs.github.io/solana-web3.js/) on Solana, as well as Bitcoin, TON, TRON and other networks.

<Note>
  These steps are specific to [Next.js](https://nextjs.org/) app router. For other React frameworks
  read the [React documentation](../../react/core/installation).
</Note>

## Installation

Try installing AppKit Skills to get AI-assisted guidance. Your AI coding assistant can help you set up, build, and debug your AppKit integration.

To install AppKit Skills, run the following command in your terminal:

```bash
npx skills add https://github.com/reown-com/skills --skill appkit --agent '*'
```

After installation, you can ask your AI assistant for help with AppKit setup, implementation, and troubleshooting.

## Trigger the modal

<Tabs>
<Tab title="AppKit">

To open AppKit you can use our [**React components**](/appkit/react/core/components) or build your own button with AppKit [**hooks**](/appkit/react/core/hooks#useAppKit).

<CodeGroup>

```tsx ConnectButton.tsx
import { AppKitButton } from '@reown/appkit/react'

export default function ConnectButton() {
  return <AppKitButton />
}
```

```tsx ConnectButtonWithHooks.tsx
import { useAppKit } from '@reown/appkit/react'

export default function ConnectButton() {
  const { open } = useAppKit()

  return (
    <>
      <button onClick={() => open()}>Open Connect Modal</button>
      <button onClick={() => open({ view: 'Networks' })}>Open Network Modal</button>
    </>
  )
}
```

</CodeGroup>

</Tab>
<Tab title="AppKit Core">

To open AppKit Core you need to call the `connect` function from the Universal Connector.

```tsx
// get the session from the universal connector
const handleConnect = async () => {
  if (!universalConnector) {
    return
  }

  const { session: providerSession } = await universalConnector.connect()
  setSession(providerSession)
}

// disconnect the universal connector
const handleDisconnect = async () => {
  if (!universalConnector) {
    return
  }
  await universalConnector.disconnect()
  setSession(null)
}

...

return (
  <div>
    <button onClick={handleConnect}>Open AppKit Core</button>
    <button onClick={handleDisconnect}>Disconnect</button>
  </div>
)
```

</Tab>
</Tabs>

## Smart Contract Interaction

<Tabs>
<Tab title="Wagmi">

[Wagmi hooks](https://wagmi.sh/react/api/hooks/useReadContract) can help us interact with wallets and smart contracts:

```tsx
import { useReadContract } from 'wagmi'
import { USDTAbi } from '../abi/USDTAbi'

const USDTAddress = '0x...'

function App() {
  const result = useReadContract({
    abi: USDTAbi,
    address: USDTAddress,
    functionName: 'totalSupply'
  })
}
```

Read more about Wagmi hooks for smart contract interaction [here](https://wagmi.sh/react/hooks/useReadContract).

</Tab>
<Tab title="Ethers">

[Ethers](https://docs.ethers.org/v6/) can help us interact with wallets and smart contracts:

```tsx
import { useAppKitProvider, useAppKitAccount } from '@reown/appkit/react'
import { BrowserProvider, Contract, formatUnits } from 'ethers'

const USDTAddress = '0x617f3112bf5397D0467D315cC709EF968D9ba546'

// The ERC-20 Contract ABI, which is a common contract interface
// for tokens (this is the Human-Readable ABI format)
const USDTAbi = [
  'function name() view returns (string)',
  'function symbol() view returns (string)',
  'function balanceOf(address) view returns (uint)',
  'function transfer(address to, uint amount)',
  'event Transfer(address indexed from, address indexed to, uint amount)'
]

function Components() {
  const { address, caipAddress, isConnected } = useAppKitAccount()
  const { walletProvider } = useAppKitProvider('eip155')

  async function getBalance() {
    if (!isConnected) throw Error('User disconnected')

    const ethersProvider = new BrowserProvider(walletProvider)
    const signer = await ethersProvider.getSigner()
    // The Contract object
    const USDTContract = new Contract(USDTAddress, USDTAbi, signer)
    const USDTBalance = await USDTContract.balanceOf(address)

    console.log(formatUnits(USDTBalance, 18))
  }

  return <button onClick={getBalance}>Get User Balance</button>
}
```

</Tab>
</Tabs>

## Extra configuration

Next.js relies on [SSR](https://nextjs.org/docs/pages/building-your-application/rendering/server-side-rendering). This means some specific steps are required to make AppKit work properly.

- Add the following code in the `next.config.js` file

```ts
// Path: next.config.js
const nextConfig = {
  webpack: config => {
    config.externals.push('pino-pretty', 'lokijs', 'encoding')
    return config
  }
}
```

## Alternative Installation

If you are starting from scratch, you can use the following methods to set up your project with Reown AppKit.

<AccordionGroup>
<Accordion title="AppKit Skills">
  AppKit Skills provide AI-powered assistance for building with Reown AppKit. Once installed, your AI coding assistant can help you set up, build, and debug your AppKit integration.

To install AppKit Skills, run the following command in your terminal:

```bash
npx skills add https://github.com/reown-com/skills --skill appkit --agent '*'
```

After installation, you can ask your AI assistant for help with AppKit setup, implementation, and troubleshooting.

</Accordion>
<Accordion title="AppKit CLI">
  Reown offers a dedicated CLI to set up a minimal version of AppKit in the easiest and quickest way possible.

To do this, please run the command below.

```bash
npx @reown/appkit-cli
```

After running the command, you will be prompted to confirm the installation of the CLI. Upon your confirmation, the CLI will request the following details:

1. **Project Name**: Enter the name for your project.
2. **Framework**: Select your preferred framework or library. Currently, you have three options: React, Next.js, and Vue.
3. **Network-Specific libraries**: Choose whether you want to install Wagmi, Ethers, Solana, or Multichain (EVM + Solana).

After providing the project name and selecting your preferences, the CLI will install a minimal example of AppKit with your preferred blockchain library. The example will be pre-configured with a `projectId` that will only work on `localhost`.

To fully configure your project, please obtain a `projectId` from the Reown Dashboard and update your project accordingly.

**Refer to [this section](#cloud-configuration) for more information.**
