metaMask

Connector for the MetaMask SDK.

WARNING

This connector has limitations on iOS as Safari cancels Universal Link connections if they do not occur within ~500ms of user interaction (ie. a button click). For a reliable iOS linking experience, it is recommended to use the walletConnect connector.

Alternatively, to prevent Universal Link issues with this connector, you can skip transaction validation by setting gas: null (for transactions) or __mode: 'prepared' (for contract writes).

tsx
import { useSendTransaction, parseEther } from 'wagmi'

function Example() {
  const { sendTransaction } = useSendTransaction()
  
  return (
    <button 
      onClick={() => sendTransaction({ 
        gas: null,
        to: '0xd2135CfB216b74109775236E36d4b433F1DF507B',
        value: parseEther('0.01'), 
      })}
    >
      Transfer
    </button>
  )
}
tsx
import { useWriteContract } from 'wagmi'
import { abi } from './abi'

function Example() {
  const { writeContract } = useWriteContract()
  
  return (
    <button 
      disabled={!isSuccess}
      onClick={() => writeContract({
        __mode: 'prepared',
        abi,
        address: '0x6b175474e89094c44da98b954eedeac495271d0f',
        functionName: 'mint',
      })}
    >
      Mint
    </button>
  )
}
