The extensions menu on Passport offers a simple way to enable extra features on Passport. Enabling extensions from this screen creates menu items that allow you to use Passport with specific types of third party software.
¶ Casa
The Casa extension adds an additional account screen with extra, Casa specific features to make using Passport with the Casa platform easy. Video tutorial coming soon!
¶ Sign with QR Code
Sign a transaction by scanning QR codes as you would any other Passport account.
¶ Sign with microSD
Sign a transaction by selecting a file from an inserted microSD card, just as you would with any other Passport account.
¶ Verify Address
Verify a receive address being displayed by the Casa app.
Please note that Casa does not currently offer a multisig configuration file export option. This means that Passport will not be able to verify receive addresses displayed by the Casa app, even though that device is one of three keys in the setup. We'll shortly be posting a blog post on how to recreate your Casa wallet within Sparrow to successfully verify Casa receive addresses.
¶ Health Check
Periodically test that Passport is still successfully connected and to your Casa account and ensures that Passport can sign transactions. This can be done via QR code or microSD, depending on your preference.
¶ Connect to Casa
Connect Passport with your Casa account and have it act as one of the keys in your collaborative custody solution. This can be done via QR code or microSD, depending on your preference.
¶ Postmix
The Postmix extension adds an additional account screen with a pre-configured account derivation m/84'/0'/2147483646'. Once enabled, this account behaves in the exact same way as a typical account does on Passport. The only difference being that, when used in conjunction with a desktop Whirlpool client like Sparrow Wallet, it offers users the ability to mix directly to cold storage, but then subsequently continue remixing, for free, at any time in the future.
Full details on using the Postmix extension on Passport in conjunction with the Sparrow Wallet Whirlpool client.
¶ Sign with QR Code
Sign a transaction by scanning QR codes as you would any other Passport account.
¶ Sign with microSD
Sign a transaction by selecting a file from an inserted microSD card, just as you would with any other Passport account.
¶ Verify Address
Verify that the receive address being displayed by your chosen wallet software actually belongs to your Passport.
¶ Connect Wallet
Connect the Postmix account to any compatible Software Wallets. At the time of writing, Sparrow Wallet offers the best compatability with Whirlpool accounts.
