Multi-signature wallet setup
Remove the single point of failure from your Bitcoin. Professional multisig configuration with redundant backups held in separate secure facilities.
One seed phrase is one point of failure
Most self-custodied crypto sits behind a single twelve or twenty-four word recovery phrase. Whoever has those words controls the funds completely. That means one written page, in one location, standing between you and permanent loss — and simultaneously between a thief and everything you hold.
The two risks pull in opposite directions. Making the phrase harder to steal makes it easier to lose. Making it easier to recover makes it easier to take. With a single key there is no arrangement that improves both at once.
How multi-signature changes the arithmetic
A multi-signature wallet requires several independent keys to authorise a transaction. A common arrangement is two-of-three: three keys exist, any two can move funds, and no single key can do anything alone.
That structure breaks the trade-off. Losing one key is survivable — the remaining two still work. A thief who steals one key gets nothing. And keys can be held in different places, by different people, under different conditions, so no single fire, flood, burglary or accident reaches all of them.
Multi-signature is how you give your executor a genuine path to your holdings without giving anyone unilateral control while you are alive. One key with you, one with your law firm, one in secure storage — and a documented procedure that only assembles a quorum on the triggering event.
What we do
Design the quorum
How many keys, how many are required, and who holds them. We work through the realistic failure cases with you — not just theft, but divorce, incapacity, a falling-out, a house fire, and the death of a keyholder.
Configure the wallet
Hardware devices initialised and verified, the wallet built and tested with small amounts before anything material moves. You hold your own keys throughout.
Create and place backups
Redundant backups produced in durable form and placed in physically separate secure facilities, with an access log and a documented retrieval procedure.
Test recovery
We rehearse the recovery before you rely on it. An untested backup is an assumption, and assumptions are what fail at exactly the wrong moment.
Document the protocol
Written instructions your executor or attorney can follow — specific enough to act on, general enough to survive a change of hardware.
What it does not do
Multi-signature is not a cure-all. It adds complexity, and complexity carries its own failure modes: more devices, more backups, more to keep current. A poorly documented multisig arrangement can be harder for an estate to recover than a simple one. It is the right answer for meaningful holdings that need a survivable custody structure — and overkill for a small balance you actively trade.
We will tell you if you do not need it.
