Unwrenchable

Planned home appliance · not yet built

Make the owner unwrenchable.

A wrench attack works only because the owner can hand over everything, quickly. Unwrenchable is a box for your home, designed so that forcing you to move your holdings is pointless: withdrawals are slow, cancellable, and need people an attacker cannot reach.

How it is designed to work

Remove the thing an attacker is trying to buy: speed.

This is the plan, not a shipped product. Each line below describes what the box is designed to do.

  1. Slow, cancellable withdrawals

    Large movements are designed to sit in a waiting period before anything leaves. Until it ends, the move can be cancelled.

  2. Guardians who can only say no

    You name people, such as a lawyer, a relative abroad, a custodian. They are designed to be able to cancel, never to approve something fast.

  3. A small walking-around amount

    A capped sum for daily life stays easy to spend. The cap is designed to limit what any single bad day can cost.

  4. An optional decoy view

    If you choose it, the box can show a small balance instead of the real one when you are made to open it.

  5. It notices duress

    The box is designed to watch behaviour across your own devices. If something looks like pressure, it locks down and needs people the attacker cannot reach.

  6. Your hardware, your data

    Everything is designed to stay on equipment you own, in your home. No account with us holds your holdings.

Who it is for

Law-abiding owners, and the families who share the risk.

  • Holders whose wealth is public enough, or guessable enough, to make them a target.
  • Families who want a plan that does not depend on one frightened person making one fast decision.
  • Owners who already use advisers, lawyers or custodians and want them built into the process.
  • Anyone who would rather an attacker find the effort pointless than hope never to meet one.

Plainly

What this is not, and where it stands.

  • Not built yet. Unwrenchable is a design. There is no product to buy and no shipping date.
  • Not a promise of safety. It is designed to make coercion pointless. No design can guarantee how a criminal will behave.
  • Not a way around the law. It exists to protect law-abiding owners from criminals.
  • Reservations are refundable. A deposit holds a place in line. Units are to be built in the order deposits arrive.

Join the line before the first unit exists.

Reserving takes a short form. A representative will reach you by the method you choose and explain the refundable $250 deposit.
