Bitcoin is infrastructure.
Your custody should be engineered infrastructure.
Not a setup. Not a wallet choice. A system designed to survive time, people, and stress.
The Custody Atrophy Effect
Most Bitcoin holders believe custody is "done" once keys are generated.
That belief is the problem.
Custody rarely fails because of hackers. It fails quietly, over time.
Devices change. Backups decay. People move. Trust assumptions drift. Legal reality diverges from technical reality.
When stress arrives—death, incapacity, coercion, urgency—the system that looked secure on paper stops working.
This is the Custody Atrophy Effect: slow degradation that goes unnoticed until failure is irreversible.
What Custody Actually Is
Bitcoin custody is not a product.
It is not a wallet. It is not multisig by itself. It is not a one-time configuration.
Bitcoin custody is infrastructure.
Infrastructure must be designed against failure modes, validated—not assumed—maintained over time, and audited as conditions change.
Anything else is optimism.
Custody Infrastructure Design
GreenChain helps serious Bitcoin holders design, validate, and maintain custody infrastructure that survives real-world conditions.
We do not take custody. We do not touch keys. We do not sell wallets.
We design systems and verify that they actually work.
Our work focuses on recovery under loss scenarios, inheritance and continuity across people, minimizing trust assumptions, eliminating single points of failure, and establishing an operational cadence so custody does not decay.
This is custody validated, not just configured.
The ARCHITECT System
- Assess
Threat models and real-life constraints.
- Reframe
Custody as infrastructure, not setup.
- Construct
Redundancy and recovery paths.
- Harden
Against loss, coercion, and error.
- Implement
Without introducing new trust risks.
- Check
Assumptions through drills and reviews.
- Evolve
As life, assets, and jurisdictions change.
- Track
Custody health over time.
For you if
- You hold a meaningful amount of Bitcoin
- You self-custody or plan to
- You care about recovery and inheritance
- You want certainty, not reassurance
Not for you if
- You want price predictions or investment advice
- You believe multisig alone solves everything
- You want shortcuts or tools without thinking
- You are unwilling to review or test your setup
Where custody often fails
- Secure setups that have never been tested
- Backups no longer accessible in practice
- Heirs without a viable recovery path
- Multisig systems that fail under stress
- Legal documents misaligned with technical reality
Tools
- Custody Risk Assessment
- Custody Atrophy Explainer
- Documentation templates designed to avoid key leakage
These tools clarify risk. They do not replace an audit.
If your Bitcoin matters, your custody cannot rely on assumptions.
Nothing more. Nothing less.
