The Web Wallet is a simple wallet app to view addresses and balances as well as send transactions from your device's active wallet. Easily switch between Lattice1 and SafeCard wallets with the push of a button. Currently supports sending ETH, BTC, and some ERC20 tokens. Also supports arbitrary data for Ethereum transactions.
Before you can pair with your device, you must know your Device ID. You can find this on your Lattice's home screen under the menu option "Device ID". Enter this into your web wallet login screen and choose a password you wish to use going forward. You define this password; it is not saved anywhere and is simply used to establish a secure connection between your web wallet and your Lattice1 device.
You may switch wallets at any time on your Lattice1 device by inserting or removing SafeCards. When there is no SafeCard inserted, it means you are using the Lattice1 wallet. When on this wallet, your home screen will show "Lattice1 Addresses" as the first item. If you wish to switch to a SafeCard wallet, insert and unlock the card. Your home screen will now show "SafeCard Addresses" as the first item. On the web wallet, you simply press the button on the top right of the screen (it should tell you the wallet it currently knows about) - this will refresh the connection with the Lattice1 and will update the current wallet to whatever is active on your device.
If you forget your password or reset your device's router, you will need to remove the old connection with the GridPlus Web Wallet and re-pair with the app. On your Lattice1 home screen, navigate to "Permissions" and "GridPlus Web Wallet", then remove the item. You may now repair by refreshing your web wallet window. If you logged out and want to set a new password, you may do that now.
