# Production readiness

When using MetaMask Connect EVM, ensure your dapp is production ready by focusing on these key areas unique to MetaMask:

- [Wallet connection and mobile compatibility](#wallet-connection-and-mobile-compatibility)
- [Reliable RPC endpoints](#reliable-rpc-endpoints)
- [Error handling and recovery](#error-handling-and-recovery)

## Wallet connection and mobile compatibility[​](#wallet-connection-and-mobile-compatibility "Direct link to Wallet connection and mobile compatibility")

- **Cross-platform testing** - Verify that your dapp's wallet connection flow works seamlessly on desktop (via the MetaMask browser extension) and mobile devices (via QR codes or deeplinks).
- **Responsive UI** - Ensure that touch interactions and responsive layouts are optimized for mobile users.

## Reliable RPC endpoints[​](#reliable-rpc-endpoints "Direct link to Reliable RPC endpoints")

- **Custom RPC setup** - Use production-grade RPC endpoints and custom API keys by signing up on [Infura](https://app.infura.io/). This improves reliability over public nodes.
- **Configuration** - Configure your Wagmi (or MetaMask Connect EVM) setup with your custom RPC URL using environment variables. For example:  
Configure custom RPC endpoint  
```  
import { http, createConfig } from 'wagmi'  
import { mainnet } from 'wagmi/chains'  
import { metaMask } from 'wagmi/connectors'  
export const config = createConfig({  
  chains: [mainnet],  
  connectors: [metaMask()],  
  transports: {  
    [mainnet.id]: http(process.env.NEXT_PUBLIC_METAMASK_RPC_URL),  
  },  
})  
```

## Error handling and recovery[​](#error-handling-and-recovery "Direct link to Error handling and recovery")

- **Clear feedback** - Display user-friendly messages when wallet connection or transaction errors occur (for example, network switch failures or user rejections).
- **Event management** - If you're using Vanilla JavaScript, handle MetaMask events such as [chainChanged](/metamask-connect/evm/reference/provider-api/#chainchanged)and [accountsChanged](/metamask-connect/evm/reference/provider-api/#accountschanged) to promptly update the UI and internal state. If you're using Wagmi, you generally don't need to handle MetaMask events, because the hooks will handle the events for you.
