H33 Custody › Asset Custody › Bitcoin Inheritance
Asset Custody · Solution
Bitcoin doesn't inherit. Until now.
Bitcoin was designed for sovereignty, not succession. The private key is yours alone — and so is the responsibility of moving it to your heirs. H33 Bitcoin Inheritance gives you a succession layer the original protocol never included.
The cost of holding Bitcoin without inheritance planning
Independent analyses have estimated that a meaningful portion of all Bitcoin ever mined is permanently lost — much of it from holders who died without transferring their keys. Some are early adopters whose families didn't know they held it. Some are HNW investors who explicitly chose not to write the seed phrase anywhere a third party could find it. Either way, the result is the same: bitcoin that exists on the chain, with no living person able to spend it.
Beneficiaries instead of seed-phrase hand-offs
H33 Bitcoin Inheritance lets you keep custody — entirely on your terms, with no third party holding your keys — while designating the beneficiaries who can recover access on defined events. Death. Incapacitation. Time-based release. Multi-beneficiary verification. Whatever your estate plan calls for.
Cold-storage compatible
Air-gapped hardware, multi-signature setups, and other self-custody patterns are fully compatible. The H33 layer adds beneficiary designation and verifiable handoff — without changing how you hold the underlying keys today.
Verifiable to executors and trustees
When the time comes, your executor can prove the holding existed, prove the beneficiary designation was valid, and prove the transfer followed the rules — without ever needing to find the seed phrase you may not have written down.
