usePublicClient

Hook for getting Viem PublicClient instance.

Import

ts
import { usePublicClient } from 'wagmi'

Usage

tsx
import { usePublicClient } from 'wagmi'

function App() {
  const client = usePublicClient()
}
ts
import { http, createConfig } from 'wagmi'
import { mainnet, sepolia } from 'wagmi/chains'

export const config = createConfig({
  chains: [mainnet, sepolia],
  transports: {
    [mainnet.id]: http(),
    [sepolia.id]: http(),
  },
})

WARNING

If you want to optimize bundle size, you should use useClient along with Viem's tree-shakable actions instead. Since Public Client has all public actions attached directly to it.

Parameters

import { type UsePublicClientParameters } from 'wagmi'

chainId

config['chains'][number]['id'] | undefined

ID of chain to use when getting Viem Public Client.

ts
import { usePublicClient } from 'wagmi'

    chainId: mainnet.id, 
  })
}
ts
import { http, createConfig } from '@wagmi/core'
import { mainnet, sepolia } from '@wagmi/core/chains'

  transports: {
    [mainnet.id]: http(),
    [sepolia.id]: http(),
  },
})
