Securing Your Bitcoin For the Next Generation.
Providing estate planners and clients with expert consulting and technical support to ensure your Bitcoin is protected during your lifetime - and reaches your family after.
Free, no-obligation. 15-30 minutes. Australian-based.
Two audiences. One unbroken chain of custody.
We sit between Bitcoin self-custody and traditional estate law - the gap that costs families everything.
A specialist partner for the conversation you can't have alone.
Co-advise clients with significant Bitcoin holdings. We handle the custody mechanics; you handle the estate. Our documents are reviewed by a partner succession law firm.
Secure your Bitcoin. Protect your family.
Move off the exchange and into multisig self-custody, paired with a digital asset estate plan that's enforced by the wallet - not just written on paper.
Online wills don't understand crypto. Crypto firms don't understand estates.
Traditional wills don't address private keys, multisig structures, or custody mechanics. Executors are left with no way to access self-custodied assets.
Crypto platforms hold funds at single points of failure and have no answer for what happens when a holder dies. The gap between the two costs Australian families billions every year.
Bitcoin estimated permanently lost.
of holders haven't shared keys with family.
of holders include crypto in their estate plan.
Every engagement is led by a senior member of our team, alongside our partner succession lawyers. No offshore support, no handoffs.
Three pillars. One unbreakable system.
Asset Mapping
We document what you hold, where you hold it and how your family can access your assets when you can't - without ever needing to know your private keys.
Self-Custody
Whether you want to use 1, 3 or 5 private keys is up to you. We provide you with a step-by-step guide on how to implement self-custody that can last generations.
Passing It On
We work with lawyers, estate planners, executors and beneficiaries to provide the instructions on how to access your digital asset estate so that nothing is left to chance.
Fixed-price engagements from $295.
All fees in Australian dollars and inclusive of GST. We are strictly non-custodial and you retain sole control of your keys at every stage.

"BlockByte bridged the gap between our succession practice and our client's Bitcoin holdings. Their process is rigorous and their documents slot straight into our estate pack."
"I'd been putting off the estate side of my Bitcoin for years. In one engagement they had my custody restructured and a plan my wife and executor can actually follow."
"The Executor Pack is the piece nobody else was doing. It's the difference between a family recovering the coins and them being lost forever."
