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).
