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.
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.

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 eliminates single points of failure
- 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
- No single point of failure for 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
- Professionals (executors, trustees) lack credentials or training to execute recovery
- No documented procedures exist for beneficiaries to follow
Collaborative security solves both problems: You get professional self-custody with multisig architecture, hardware wallet integration, and ongoing support. Simultaneously, you get comprehensive inheritance planning with documented protocols, beneficiary education, and legal coordination. Learn more about estate planning →

- 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
- No single points of failure
- Comprehensive inheritance planning included
- 24/7 professional oversight
- Family gets documented, simple procedures
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 removing a single point of failure.
- 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.
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.
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.

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.
