# Other Use Cases

> Access the Coinbase Wallet provider from Wagmi for advanced functionality like Sub Accounts, Spend Permissions, and more

Learn how to access the Coinbase Wallet provider through Wagmi to unlock advanced Coinbase Wallet features beyond basic authentication and payments.

## Prerequisites

Make sure you have [set up Wagmi with Coinbase Wallet](/coinbase-wallet/framework-integrations/wagmi/setup) before following this guide.

## Getting the Provider

The key to accessing advanced Coinbase Wallet functionality is getting the provider from your Wagmi connector. Once you have the provider, you can use any Coinbase Wallet RPC method.

<CodeGroup>
  ```tsx Hook lines wrap expandable theme={null}
  // hooks/useBaseAccountProvider.ts
  import { useConnections } from 'wagmi'
  import { useEffect, useState } from 'react'
  import { EIP1193Provider } from 'viem'

  export function useBaseAccountProvider() {
    const connections = useConnections()
    const [provider, setProvider] = useState<EIP1193Provider | null>(null)

    useEffect(() => {
      const connection = connections[0]

      if (!connection) {
        setProvider(null)
        return
      }

      connection.connector.getProvider().then((provider) => {
        setProvider(provider as EIP1193Provider)
      })
    }, [connections])

    return provider
  }
  ```

  ```tsx Component lines wrap expandable theme={null}
  // components/BaseAccountFeatures.tsx
  import { useBaseAccountProvider } from '../hooks/useBaseAccountProvider'
  import { useAccount } from 'wagmi'

  export function BaseAccountFeatures() {
    const { address, isConnected } = useAccount()
    const provider = useBaseAccountProvider()

    const callProviderMethod = async (method: string, params: any[]) => {
      if (!provider) {
        console.error('Provider not available')
        return
      }

      try {
        const result = await provider.request({
          method,
          params
        })
        console.log(`${method} result:`, result)
        return result
      } catch (error) {
        console.error(`${method} error:`, error)
        throw error
      }
    }

    if (!isConnected) {
      return <p>Please connect your wallet to access Coinbase Wallet features</p>
    }

    return (
      <div className="space-y-4">
        <h2 className="text-xl font-bold">Coinbase Wallet Features</h2>
        <p className="text-gray-600">
          Connected with Coinbase Wallet provider. You can now access advanced features.
        </p>
      </div>
    )
  }
  ```
</CodeGroup>
