Client

Client

The wagmi Client is a framework agnostic (Vanilla JS) client that manages wallet connection state and configuration, such as: auto-connection, connectors, and ethers providers.

import { createClient } from 'wagmi'

Usage

import { createClient, configureChains, defaultChains } from 'wagmi'
import { publicProvider } from 'wagmi/providers/public'

const { provider, webSocketProvider } = configureChains(defaultChains, [
  publicProvider(),
])

const client = createClient({
  provider,
  webSocketProvider,
})

Configuration

autoConnect (optional)

Enables reconnecting to last used connector on mount. Defaults to false.

import { createClient, configureChains, defaultChains } from 'wagmi'
import { publicProvider } from 'wagmi/providers/public'

const { provider } = configureChains(defaultChains, [publicProvider()])

const client = createClient({
  autoConnect: true,
  provider,
})

connectors (optional)

Connectors used for linking accounts. Defaults to [new InjectedConnector()].

import { createClient, configureChains, defaultChains } from 'wagmi'
import { publicProvider } from 'wagmi/providers/public'
import { InjectedConnector } from 'wagmi/connectors/injected'
import { WalletConnectConnector } from 'wagmi/connectors/walletConnect'

const { chains, provider } = configureChains(defaultChains, [publicProvider()])

const client = createClient({
  connectors: [
    new InjectedConnector({ chains }),
    new WalletConnectConnector({
      chains,
      options: {
        qrcode: true,
      },
    }),
  ],
  provider,
})

provider

ethers interface for connecting to the Ethereum network.

import { createClient, configureChains, defaultChains } from 'wagmi'
import { publicProvider } from 'wagmi/providers/public'

const { provider } = configureChains(defaultChains, [publicProvider()])

const client = createClient({
  provider,
})

storage (optional)

The default strategy to persist and cache data. Defaults to window.localStorage.

import { createClient, configureChains, defaultChains } from 'wagmi'
import { publicProvider } from 'wagmi/providers/public'

const { provider } = configureChains(defaultChains, [publicProvider()])

const client = createClient({
  provider,
  storage: createStorage({ storage: window.localStorage }),
})

webSocketProvider (optional)

ethers WebSocket interface for connecting to the Ethereum network. If you provide a WebSocket provider, it will be used instead of polling in certain instances.

import { createClient, configureChains, defaultChains } from 'wagmi'
import { publicProvider } from 'wagmi/providers/public'

const { provider, webSocketProvider } = configureChains(defaultChains, [
  publicProvider(),
])

const client = createClient({
  provider,
  webSocketProvider,
})
