Governance-Controlled Bitcoin Security Built for Inheritance

Collaborative Security is our three-party operating model built on standard 2-of-3 multisig. It eliminates unilateral control while keeping you in charge of every spend. We combine robust technical controls with documented recovery and inheritance readiness so your Bitcoin remains secure and usable through life events, personnel change, and generational transition.

Important: This is not a custodian and not an exchange. You maintain full control of your keys and Bitcoin at all times.

Quick Read

  • No unilateral control: no one, not you, not us, not the platform, can move funds alone.
  • You initiate: you trigger transactions; we only co-sign after your authorization.
  • Inheritance-ready: an Estate Plan Protocol (EPP) turns “keys” into an actionable recovery process.
  • Operational support: optional reviews, key health checks, rehearsals, and incident response.
  • Built for scale: individuals, families, and family offices with governance requirements.

Why We Built It

Most loss events come from one of three failure modes: counterparty failure (exchanges/custodians), single-signer failure (lost key, death, incapacity), or operational ambiguity (no clear procedure under pressure). Collaborative Security reduces all three by separating duties and documenting execution.

Combined Service

Services for Bitcoin Self-Custody and Inheritance Planning

Collaborative Security provides both professional Bitcoin self-custody and comprehensive inheritance planning in one integrated solution. Unlike DIY self-custody that leaves inheritance as an afterthought, or inheritance planning without proper custody structure, collaborative security addresses both needs simultaneously.

Bitcoin Self-Custody

  • You maintain full control: initiate every transaction
  • Hardware wallet integration (Trezor recommended)
  • 2-of-3 multisig with distributed responsibility
  • Professional oversight without sacrificing sovereignty
  • 24/7 incident response for lost keys or device failures

Inheritance Planning

  • Documented Estate Plan Protocol (EPP) for heirs
  • Beneficiary education and training programs
  • Multisig architecture protects beneficiaries
  • Legal coordination with wills and trusts
  • Seamless transition to next generation

Why Self-Custody Needs Inheritance Planning

Self-custody alone doesn't solve inheritance challenges. Research shows that 28% of Bitcoin is lost forever due to lost private keys, forgotten passwords, death without proper planning, and technical complexity for heirs. Even technically perfect self-custody setups fail when:

  • Heirs inherit seed phrases without understanding how to use them
  • Single-signer custody means funds are frozen when the key holder is gone
  • No documented procedures exist for beneficiaries to follow

Self-Custody Alone

  • You control your keys
  • No professional fees
  • Requires technical expertise
  • Single-signer risk (key loss = frozen funds)
  • Inheritance planning is DIY
  • No professional oversight
  • Family must become Bitcoin experts

Collaborative Security with Inheritance

  • You control your keys (2-of-3 multisig)
  • 1% annual fee for professional service
  • Professional handles complexity
  • Multisig architecture eliminates single-signer risk
  • Comprehensive inheritance planning included
  • 24/7 professional oversight
  • Family gets documented, simple procedures
Framework Overview

How the Model Works

Three Independent Key Agents

  • You: hold a key and initiate transactions.
  • Technology partner (Theya or Unchained): vault platform and coordination layer.
  • The Bitcoin Adviser: security oversight, continuity support, and co-signing under your authorization.

Two Signatures Required

  • Quorum-based spending: 2-of-3 signatures are required for every spend.
  • Redundancy without surrender: you retain control while distributing responsibility across multiple keys.
  • Continuity by design: documented procedures keep the system executable for trustees/heirs.

Control Map (Plain English)

Role Holds a key? Can initiate spends? Can move funds alone?
You Yes Yes No (needs one co-signer)
Technology partner (Theya/Unchained) Yes No No (needs one co-signer)
The Bitcoin Adviser Yes No No (needs one co-signer)

Put simply: you remain sovereign, and the system stays recoverable if life happens.

Spending & Authorization

How a Withdrawal Works

1 · You Initiate

You initiate the transaction from your account. You always remain the originator of spending intent.

2 · Authorization & Verification

We co-sign only after your authorization. For higher-risk events (e.g., large withdrawals, address changes, unusual patterns), we may use additional verification steps.

3 · Co-Signing & Broadcast

Once authorized, the required co-signer signs and the transaction can be broadcast. You can maintain your own records and reporting for accountants, auditors, trustees, or committees.

Reasonable Safety Checks (Not Friction)

Collaborative Security is designed to prevent catastrophic outcomes without turning spending into a bureaucratic process. When additional checks are required, they are applied to the risk event (e.g., address change), not to normal day-to-day control.

Implementation

From Setup to Ongoing Operations

1 · Onboard

Choose a vault platform (Theya or Unchained), coordinate key creation, confirm roles, and capture key contacts for continuity planning.

2 · Operate

View balances anytime, initiate transactions when required, and maintain a clear, repeatable workflow for approvals and records.

3 · Maintain

Optional periodic reviews: key health checks, device refreshes, role updates, and rehearsals to prevent “governance drift” over time.

Client Proof

What Our Clients Say

★★★★★

"The biggest challenge I needed to overcome in getting comfortable with self-custody of Bitcoin was the security risk. The Bitcoin Adviser sorts that in one fell swoop. Having my own personal contact to boot puts icing on the cake!"

Nicholas ✓ Verified Client
★★★★★

"Self custodying my BTC with TBA's services has allowed me to feel safe for my own retirement and my family's future. Pete and Andy are the most generous of people with their time and care, always accessible."

Tracey ✓ Verified Client
Inheritance is the Constraint

Self-Custody That Survives Real Life

Most Bitcoin custody setups optimize for storage, not execution under stress. Collaborative Security is designed for the moments that break DIY systems: incapacity, death, loss of a device, role turnover, and family coordination under time pressure.

Common Failure Modes

  • Heirs receive words or devices with no practical procedure.
  • Single-signer custody freezes when the key holder is unavailable.
  • Trustees/executors have legal authority but no technical control path.
  • No rehearsed or documented process exists for recovery.

What We Deliver

  • Documented Estate Plan Protocol (EPP) aligned to your structure.
  • Beneficiary and fiduciary readiness (education + optional rehearsals).
  • Role clarity and continuity planning to prevent drift over time.
  • Coordination support with your legal team where relevant.

FAQ

Common Questions

Can The Bitcoin Adviser move my Bitcoin without me?
No. The system is designed so no single party can move funds alone. You initiate spending intent, and co-signing occurs only after your authorization, with 2-of-3 required.
Is this "custody" or self-custody?
It is best described as governance-controlled self-custody: standard multisig architecture plus documented processes that keep Bitcoin secure, recoverable, and transferable across life events.
What happens if I lose a device or a key?
The model is built for recoverability. With 2-of-3, a single failure does not freeze funds. We guide the recovery process and help restore the system to a healthy state (including key/device refresh where appropriate).
How do you handle inheritance and trustees/executors?
Through a documented Estate Plan Protocol (EPP) and optional education/rehearsals. The goal is to give fiduciaries an executable procedure, not a "bag of keys" with no operating manual.
Where should I start if I'm new to this?
Start with your knowledge base and guides: Security Centre, What to Expect, Buy Bitcoin Resources, and FAQs. Then book a working session to implement properly.
