Non-custodial
Your keys never leave your device. Heirsgate only ever holds one half of a key — and half a key opens nothing.
non-custodial · zero-knowledge inheritance
Your wealth should outlive you.
Self-custody means your keys are yours alone — and they should stay that way. Heirsgate makes sure what you built still reaches the people you choose, without ever handing your keys to anyone.
Zero-knowledge
Our servers store only an encrypted blob and a single share. No plaintext, no way for anyone here to read what's inside.
Client-side encryption
Your secret is sealed on your device with AES-256-GCM. Its key is then Shamir-split — any m of n shares can rebuild it, and nothing less.
Human-gated release
Nothing unlocks on its own. Death verification, an identity check, and a cancelable grace window guard every claim.
Swiss-grounded
Built on a Swiss AG over a ring-fenced reserve — engineered for decades under one of the world's strongest legal frameworks.
why it matters
Self-custody shouldn't end with you.
The whole promise of crypto is that the keys are yours: no bank, no gatekeeper, only you. Heirsgate keeps that promise intact and adds the one thing self-custody was missing — a way for your circle to carry it forward when the time comes.
01
Continuity by design
Your assets don't depend on a password no one else can find. Heirsgate builds a clear path forward, set up entirely by you.
02
No single point of trust
No one person — not even Heirsgate — can move your assets. It takes your chosen circle, together, to open the vault.
03
Custody stays yours
You never hand your keys to a custodian. The reason you went self-custody in the first place stays fully intact.
the mechanism
Necessary, but not sufficient.
Heirsgate splits the key to your vault across the people you trust, plus one mandatory Heirsgate share. Our share alone is useless. Your circle alone is useless. The vault opens only when enough of them come together — after you're verified gone.
01
Encrypt
Your secret is sealed on your device. Plaintext never leaves it.
02
Split
The key is split m-of-n across your circle, plus one mandatory Heirsgate share.
03
Reveal
After death is verified and a grace window passes, the shares recombine for your heir.
the product
A vault only your heir can open.
Heirsgate is non-custodial, zero-knowledge inheritance infrastructure for self-custody crypto. You keep your keys. We hold one share that can never open your vault alone. Your heir initiates a claim; only after death and identity are verified and a grace window passes does the vault reconstruct — for them, never for us.
