Havenkey is a key-on-device wallet that leaves your recovery phrase with you and nowhere else, while still giving you a short path into on-chain software, credentials and collectibles. From one window you can sign transfers on the Ferrite and Alder networks, watch what your holdings are worth, and open a site without a password. It runs as a browser add-on and as a phone app.

Install the phone build from your device's app marketplace, then choose “Bring an existing vault” and enter the twelve recovery words you wrote down on the desktop add-on. Both copies stay in step because they read the same chain, not a shared account.

Pick your browser on the download panel above and confirm the add-on prompt. Setup takes about ninety seconds: name the vault, write the recovery words on paper, then re-enter three of them so we know the copy is readable.

It lives in the add-on tray at the top right of the browser window. Pin it there and the vault opens in a panel over whatever page you are reading, so a signing request never pulls you away from the site that asked for it.

Yes. The phone build runs on tablets at full width, and a vault can be restored on as many devices as you like from the same recovery words. Nothing is capped per seat, because there is no seat — the words are the account.
