# Multichain

AppKit is now multichain. The architecture is designed to support both EVM and non-EVM blockchains. This will allow developers and projects to choose and configure multiple blockchain networks within their instance of AppKit, extending beyond just Ethereum-based (EVM) networks.

Currently, AppKit supports two non-EVM networks, they are, **Solana** and **Bitcoin**.

## Integration

The AppKit instance allows you to support multiple chains by importing the respective chains, creating the respective network adapters and passing these within the `createAppKit()` function.

Depending on the network adapter of your preference (`Wagmi`, `Ethers`, `Ethers5`), the integration may vary. Let's look at what the integration will look like.

## Solana Adapter Configuration

The `SolanaAdapter` accepts configuration options to customize its behavior.

### registerWalletStandard

Controls whether WalletConnect is registered as an available WalletStandard wallet following the Solana Wallet Standard protocol. When enabled, users will see "WalletConnect" as a wallet choice alongside other Solana wallets like Phantom, Solflare, etc. when integrating wallet standard libraries

```ts theme={null}
const solanaWeb3JsAdapter = new SolanaAdapter({
  registerWalletStandard: true,
  wallets: [/* only show these specific wallets */]
})
```

### wallets

Array of custom Solana wallet adapters to include alongside the default WalletConnect functionality.

```ts theme={null}
import { HuobiWalletAdapter } from '@solana/wallet-adapter-wallets'

const solanaWeb3JsAdapter = new SolanaAdapter({
  registerWalletStandard: true,
  wallets: [new HuobiWalletAdapter()]
})
```
