Three tiers. Start with custody, add the rest when you're ready.

Every engagement begins with multi-signature custody, because nothing else can be built until your bitcoin is somewhere a single mistake cannot reach it. Succession planning and a private node build on that foundation and can be added at any time, including well after your custody is in place. Each tier is priced separately and confirmed on your free call. New to this? Start with what self-custody actually means.

TIER 1 · ESSENTIAL · START HERE

Multi-signature custody

A wallet that needs two or more keys to move anything, kept on separate devices in separate places. Lose one key, or have one stolen, and your bitcoin is still safe and still recoverable.

If your bitcoin is on an exchange, or behind a single key in a phone app, this is the part that shouldn't wait.

What's included. A custody design covering how many keys you hold, where each one lives and who is trusted with what. Two sessions: one where we build a practice wallet together and throw it away, and one where you build the real one yourself. A check of every backup before a single unit is moved. A plain-English recovery guide you keep.

You learn it, you don't just receive it. The first session is a rehearsal on a practice wallet, which we wipe together at the end. Then you build the real one on your own, in your own time, with nobody watching. That is the point of doing it this way: if you can build it once without us, you can rebuild it any time, and nothing you own depends on us being reachable.

Hardware. We order sealed devices from the manufacturer and have them shipped directly to you. They never pass through our hands, so there is nothing for us, or anyone else, to interfere with. We'll usually suggest a post office or parcel locker rather than your home — partly so nothing sits on a doorstep, and partly because keeping your address out of one more company's records is the same habit we apply everywhere else in your setup.

Why bitcoin only. Multi-signature is written into bitcoin's own rules, so the arrangement is enforced by every computer on the network and fixed the day it is created. Almost everywhere else it is a program somebody deployed, on one chain at a time, that can be rewritten later. Bitcoin is the only asset where you can spread your keys across devices from different manufacturers, have each device confirm the arrangement independently, and still recover everything using software from someone else entirely. That is why this practice is bitcoin only.

Format. Sessions are usually done over a video call. Face to face is available on request.

Typical design. Three keys, any two needed to spend — two hardware devices in separate places plus one on your phone. Larger holdings or several people involved: five keys, any three needed.

Already own a hardware wallet? You're ahead of most people. If yours is compatible it simply joins your quorum as one of the keys — no need to start again.

TIER 2 · ADDS TO TIER 1

Heirloom estate plan

A written, rehearsed plan so the people you leave behind can find, access and move your bitcoin, without needing to understand it and without any one of them being able to take it alone.

Learn more

What's included. A record of who holds which key and where each backup lives. Step-by-step instructions your executor follows on the day. A recovery drill with the people named in the plan, so the first time they do it is not the time it matters. A sealed heirloom pack.

Execution documents. We prepare the technical execution documents your will refers to: what exists, where it is held and exactly how it is accessed, in language an executor can follow.

Your solicitor, or ours. Use your own solicitor to incorporate the plan into your will, or we can introduce you to a solicitor we work with who is familiar with bitcoin. Either way the legal work stays with a solicitor. We supply the technical documents they build on.

TIER 3 · ADDS TO TIERS 1 & 2

Private node

Your own copy of the bitcoin ledger, running on a small device in your home. Your wallet checks its own balance and sends its own transactions without asking anyone else's server.

Learn more

Why it matters. Without your own node, your wallet asks a company's server "what is in these addresses?" every time it opens. That server now knows your addresses, your balance and your internet address, and can log, sell or leak them. With your own node, that question is answered inside your home and nobody outside learns what you hold.

What's included. The device, shipped sealed directly to you. Installation, connection to your wallets and a walk-through of how to keep it running. A follow-up check after 30 days.

Format. Usually a video call. Face to face is available on request.

Priced per tier · requires Tiers 1 & 2

Most clients start with Tier 1 and add the others once their custody is settled. Nothing about a later tier requires redoing an earlier one.

Why Quorum Practice

The biggest risk to your bitcoin isn't a hacker. It's a single point of failure.

There is no bank to call. If the only copy of a key is lost, or the only person who understood the setup is gone, the bitcoin goes with them. Most of what has been lost was never stolen at all.

OUR ANSWER

Multi-signature custody. Three keys in three places, any two can spend. Losing one is an inconvenience, not a catastrophe.

THE RISKYou are the only person who knows how any of it works.
OUR ANSWER

An heirloom plan. Written, rehearsed and sealed, so your executor and family can act without you, and no one of them can act alone.

THE RISKTrusting a company with your coins, or with knowing what you hold.
OUR ANSWER

Your own keys and your own node. Nothing sits with an exchange, and nobody's server learns your balance.

Leaving bitcoin

Bitcoin only passes on if the next person can find it and unlock it.

A bank account has a branch, a statement and a process. Bitcoin has none of those. It sits behind keys, and if the keys go with you, so does everything they protect. The rules for passing it on are settled and kinder than most people expect: there is no inheritance tax in Australia, nothing is owed when bitcoin passes to your family, and tax only arises if they later sell.

WHAT THE HEIRLOOM PACK CARRIES

Which keys are where and who holds them. A step-by-step your executor can follow. Your purchase records, so your family is taxed on the gain and not the whole amount. And notes for your solicitor on the questions that change the outcome, such as whether the bitcoin passes to your family directly or is sold by the estate first, and whether anyone named in the will lives overseas.

General information, not tax or legal advice. Your accountant and solicitor make those calls. The pack gives them what they need.

Figures rounded. Sources: Chainalysis 2026 Crypto Crime Report; Chainalysis and River Financial lost-supply research; Mt. Gox court filings; Howells v Newport City Council; Australian Taxation Office guidance on inherited assets and capital gains tax. Estimates of lost coins vary widely because a dormant coin cannot be told apart from a lost one.

How it works

From first call to a rehearsed handover.

Four stages, in order. Nothing is created until the design is agreed, and nothing is finished until your successors have recovered it themselves.

STAGE 1

Free call back

What you hold, where it sits today and who it is eventually for. Enough for us to point at the weakest link and tell you plainly whether we can help and what it would involve.

15–20 min · free · we ring you, no obligation
STAGE 2

Custody design

How many keys, which devices, where they live, how each is backed up and who holds what. A one-page plan you sign off on before anything is built.

1 week · written plan
STAGE 3

Learn it, then build it

Your hardware arrives sealed from the manufacturer, shipped straight to you. In the first session we build a practice wallet together and wipe it at the end. In the second you build the real one yourself, unwatched. You do every step both times, and we never see or touch a key.

Two sessions · video call or in person
STAGE 4

Rehearsal & handover

A recovery drill with the people named in your plan, then the sealed heirloom pack and your executor's instructions.

2 hrs · with successors
What we're not

Clear lines, so you know exactly what you're paying for.

Not a financial adviser

We never tell you what to buy, sell or hold, or when. We help you keep what you already own safe and passable.

Not an exchange

We don't sell crypto or take payment for assets. Where you acquire them is your business.

Not a custodian

We never hold, see or copy a key, recovery words or passphrase. If we could recover your funds, so could someone else.
