Security

The signature leaves. The key stays.

MaxClawOS Wallet is connected by a cable, so it is not a sealed box with no port. The isolation is narrower and more useful: the seed never crosses that cable.

  1. 01

    A request arrives

    Companion software on the computer prepares an unsigned request and sends it over USB-C.

  2. 02

    The device redraws it

    MaxClaw OS parses the request and paints the address and the action on the OLED. That paint is not a screenshot from the computer.

  3. 03

    Hands decide

    Both buttons together approve. One button, the left, clears the screen and drops the request.

  4. 04

    A signature returns

    The element signs inside the chip. The computer receives the signature and nothing it could use to sign a different request later.

What the computer is allowed to do

It can prepare a request, display its own copy, and broadcast a finished signature. It cannot read the seed, export it, or approve a session by clicking a button in a window. A click on the computer is not a press on the metal.

What the device is for

It answers a class of mistakes that showed up as soon as people kept long-lived keys on everyday laptops and phones: malware that rewrites an address on screen, and a hurried confirmation of a page the computer drew. The second screen is the countermeasure. We describe it further in the screen note.

Limits, stated plainly

A signing device does not make a person careful. If the words on the recovery card are photographed, stored in a mailbox, or read to someone on a phone, the element cannot help. If both the device and the card are lost, the studio cannot reconstruct the key, because we never held it.

We do not claim a government certification score for this enclosure, and we do not claim the device is beyond physical study. The design goal is the one the category settled on a decade ago: a readable screen, plus a chip that is a worse place to steal a key from than a general-purpose computer.
