connect

Action for connecting accounts with connectors.

Import

import { connect } from '@wagmi/core'

Usage

index.ts

import { connect } from '@wagmi/core'
import { injected } from '@wagmi/connectors'
import { config } from './config'

const result = await connect(config, { connector: injected() })

config.ts

import { http, createConfig } from '@wagmi/core'
import { mainnet, sepolia } from '@wagmi/core/chains'

export const config = createConfig({
  chains: [mainnet, sepolia],
  transports: {
    [mainnet.id]: http(),
    [sepolia.id]: http(),
  },
})

Parameters

import { type ConnectParameters } from '@wagmi/core'

chainId

number | undefined

Chain ID to connect to.

Not all connectors support connecting directly to a chainId (e.g. they don't support programmatic chain switching). In those cases, the connector will connect to whatever chain the connector's provider is connected to.

index.ts

import { connect } from '@wagmi/core'
import { mainnet } from '@wagmi/core/chains'
import { injected } from '@wagmi/connectors'
import { config } from './config'

const result = await connect(config, {
  chainId: mainnet.id, 
  connector: injected(),
})

config.ts

import { http, createConfig } from '@wagmi/core'
import { mainnet, sepolia } from '@wagmi/core/chains'

export const config = createConfig({
  chains: [mainnet, sepolia],
  transports: {
    [mainnet.id]: http(),
    [sepolia.id]: http(),
  },
})

connector

CreateConnectorFn | Connector
