Custody & estate planning

Secure your Bitcoin. Protect your family.

Institutional-grade multisig self-custody, paired with estate planning that's legally sound and cryptographically enforced.

The problem

What happens to your Bitcoin when you die?

Billions of dollars in Bitcoin are permanently lost because holders die without succession plans.

Traditional wills don't address custody mechanics, private keys, or multisig structures. Executors are left with no way to access self-custodied assets.

Existing online will platforms don't understand crypto. Crypto platforms don't understand estate law. The gap costs families everything.

60%

of crypto owners have not shared their private keys with family.

<15%

of digital asset holders have included crypto in their estate plans.

$68B+

in Bitcoin estimated permanently lost to date.

Our solution

Two layers. One unbreakable system.

Layer 01

Multisig Self-Custody

Secure 2-of-3 or 3-of-5 multisig wallets where keys are distributed across you, BlockByte, and a nominated third party. No single point of failure. No exchange risk.

Key 1
You
Personal key for active use.
Key 2
BlockByte
Released only upon a verified death event.
Key 3
Your nominee
Solicitor, family member, or trusted adviser.
Layer 02

Digital Asset Estate Planning

Legally reviewed estate planning paperwork - generated by our platform, reviewed by our partner succession law firm.

  • Digital Asset Directive (for clients without a will)
  • Digital Asset Codicil (for clients with an existing will)
  • Solicitor Briefing Pack (for your lawyer)
  • Executor Process Guide (for the person who'll manage your estate)
The process

From conversation to cryptographic enforcement, in four steps.

01

Tell us about your situation

Do you have a will? Who is your executor? We ask the right questions in plain English.

02

Set your succession plan

Nominate your digital asset executor, allocate beneficiaries, and set release conditions.

03

We generate the documents

Your Directive or Codicil is generated and reviewed by our partner succession law firm.

04

Print, sign, and you're protected

Sign in front of two witnesses. Your multisig custody enforces your wishes cryptographically.

The enforcement advantage

Your estate plan isn't just documented. It's enforced.

The multisig architecture doesn't just record your wishes; it cryptographically enforces them. Executors cannot move funds unilaterally. Beneficiaries cannot access without verification.
