Bitcoin that survives
across generations.
Multi-generational self-custody with multisig governance, inheritance planning, and expert support. No custodial counterparty risk. No single points of failure.
Why custodial solutions fail at family office scale
The stakes are higher, the time horizons are longer, and the failure modes are different from retail custody.
Custodial risk at scale is existential
A family office with $10M+ in Bitcoin on a custodial platform is one counterparty failure away from a generational loss. Mt. Gox, FTX, Celsius, Prime Trust, the list of custodial failures keeps growing.
Multi-generational custody is unsolved
Self-custody for one person is straightforward. Self-custody that survives death, incapacity, divorce, and generational transfer requires governance structures most families don't have.
Legal frameworks lag the technology
Most estate attorneys have never dealt with Bitcoin private keys. Wills and trusts written for traditional assets don't cover seed phrases, passphrases, or multisig signing ceremonies.
Technical skill varies across the family
The principal may understand self-custody. Their spouse, children, and trustees probably don't. Any custody solution that depends on everyone being technical will fail at the weakest link.
