MetaMask

The MetaMaskConnector supports connecting with MetaMask.

import { MetaMaskConnector } from '@wagmi/core/connectors/metaMask'

Usage

import { MetaMaskConnector } from '@wagmi/core/connectors/metaMask'
 
const connector = new MetaMaskConnector()

Configuration

chains (optional)

Chains supported by app. Defaults to defaultChains.

import { mainnet, optimism, polygon } from '@wagmi/core/chains'
import { MetaMaskConnector } from '@wagmi/core/connectors/metaMask'
 
const connector = new MetaMaskConnector({
  chains: [mainnet, optimism, polygon],
})

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

options (optional)

Options for configuring the connector.

import { MetaMaskConnector } from '@wagmi/core/connectors/metaMask'
 
const connector = new MetaMaskConnector({
  options: {
    shimDisconnect: true,
  },
})

shimChainChangedDisconnect

Certain versions of MetaMask emit the "disconnect" event when chain is changed. This flag prevents the "disconnect" event from being emitted upon switching chains. Defaults to true.

import { MetaMaskConnector } from '@wagmi/core/connectors/metaMask'
 
const connector = new MetaMaskConnector({
  options: {
    shimChainChangedDisconnect: false,
  },
})

shimDisconnect

MetaMask does not support programmatic disconnect. This flag simulates the disconnect behavior by keeping track of connection status in storage. Defaults to true.

import { MetaMaskConnector } from '@wagmi/core/connectors/metaMask'
 
const connector = new MetaMaskConnector({
  options: {
    shimDisconnect: false,
  },
})

UNSTABLE_shimOnConnectSelectAccount

⚠️

This is an experimental feature. It's stable enough to show up in the docs, but should be used with care. If you have any feedback, create a discussion.

While "disconnected" with shimDisconnect, allows user to select a different MetaMask account (than the currently connected account) when trying to connect. Defaults to false.

import { MetaMaskConnector } from '@wagmi/core/connectors/metaMask'
 
const connector = new MetaMaskConnector({
  options: {
    shimDisconnect: true,
    UNSTABLE_shimOnConnectSelectAccount: true,
  },
})
