# Other Use Cases

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

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

## Prerequisites

Make sure you have [set up Wagmi with Base Account](/base-account/framework-integrations/wagmi/setup) before following this guide.

## Getting the Provider

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

<CodeGroup>
  ```tsx Hook 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 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 Base Account features</p>
    }

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