Infura

The infuraProvider configures the chains with Infura RPC URLs and also provides an ethers.js InfuraProvider.

import { infuraProvider } from '@wagmi/core/providers/infura'

Usage

import { chain, configureChains } from '@wagmi/core'
import { infuraProvider } from '@wagmi/core/providers/infura'
 
const { chains, provider } = configureChains(
  [chain.mainnet, chain.polygon],
  [infuraProvider({ apiKey: 'yourInfuraApiKey' })],
)

Return Value

{
  chains: Chain[],
  provider: InfuraProvider,
  webSocketProvider: InfuraWebSocketProvider
}

Configuration

apiKey

Your Infura API key from the Infura Dashboard.

import { chain, configureChains } from '@wagmi/core'
import { infuraProvider } from '@wagmi/core/providers/infura'
 
const { chains, provider } = configureChains(
  [chain.mainnet, chain.polygon],
  [infuraProvider({ apiKey: 'yourInfuraApiKey' })],
)

priority (optional)

The priority used for the provider. Lower-value priorities are favoured over higher-value priorities. If multiple providers share the same priority, they are chosen at random.

import { chain, configureChains } from '@wagmi/core'
import { infuraProvider } from '@wagmi/core/providers/infura'
import { publicProvider } from '@wagmi/core/providers/public'
 
const { chains, provider } = configureChains(
  [chain.mainnet, chain.polygon],
  [
    infuraProvider({
      apiKey: 'yourInfuraApiKey',
      priority: 0,
    }),
    publicProvider({ priority: 1 }),
  ],
)

stallTimeout (optional)

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

import { chain, configureChains } from '@wagmi/core'
import { infuraProvider } from '@wagmi/core/providers/infura'
import { publicProvider } from '@wagmi/core/providers/public'
 
const { chains, provider } = configureChains(
  [chain.mainnet, chain.polygon],
  [
    infuraProvider({
      apiKey: 'yourInfuraApiKey',
      stallTimeout: 1_000,
    }),
    publicProvider(),
  ],
)

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/core'
import { infuraProvider } from '@wagmi/core/providers/infura'
import { publicProvider } from '@wagmi/core/providers/public'
 
const { chains, provider } = configureChains(
  [chain.mainnet, chain.polygon],
  [
    infuraProvider({
      apiKey: 'yourInfuraApiKey',
      weight: 1,
    }),
    publicProvider({ weight: 2 }),
  ],
)
