• Core
  • Providers
  • Public


The publicProvider configures the chains with a public RPC URL.

import { publicProvider } from '@wagmi/core/providers/public'


import { configureChains } from '@wagmi/core'
import { mainnet, polygon } from '@wagmi/core/chains'
import { publicProvider } from '@wagmi/core/providers/public'
const { chains, publicClient } = configureChains(
  [mainnet, polygon],

Note: The above example is using chains from @wagmi/core/chains.


Only having publicProvider in your providers will make the chain use the public RPC URL which could lead to rate-limiting. It is recommended to also include another provider in your list (such as: alchemyProvider, infuraProvider or jsonRpcProvider).

Return Value

  chains: Chain[],
  publicClient: PublicClient,
  webSocketPublicClient: PublicClient
