Public

The publicProvider configures the chains with a public RPC URL.

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

Usage

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

⚠️

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
}

Configuration

stallTimeout (optional)

The timeout in milliseconds after which another provider will be attempted.

import { chain, configureChains } from 'wagmi'
import { publicProvider } from 'wagmi/providers/public'
 
const { chains, publicClient } = configureChains(
  [chain.mainnet, chain.polygon],
  [
    alchemyProvider({ apiKey: 'yourAlchemyApiKey' }),
    publicProvider({ stallTimeout: 1_000 }),
  ],
)

weight (optional)

The weight a response from this provider provides. This can be used if a given provider is more trusted.

import { chain, configureChains } from 'wagmi'
import { publicProvider } from 'wagmi/providers/public'
 
const { chains, publicClient } = configureChains(
  [chain.mainnet, chain.polygon],
  [
    alchemyProvider({ apiKey: 'yourAlchemyApiKey', weight: 1 }),
    publicProvider({ weight: 2 }),
  ],
)
