- 01
Set up the vault
Pick a chain, deposit any amount, and write down the rules: who inherits, in what shares, after how long, with what cooling-off window.
About 10 minutes from your wallet. No KYC, no mandatory email, no waiting on support. The vault is a smart contract you own outright.
- 02
Live your life. Heartbeat once a month.
A small monthly tap that says "I'm here." Miss a few and your plan begins to wake up. Catch up anytime; nothing about a missed heartbeat is destructive.
Notifications by email, Telegram, or both. Set the cadence yourself: 30, 90, or 180 days. Stewards can grant you extra time if life gets in the way.
- 03
Optional: send standing orders today
Recurring transfers to your kids, your parents, or anyone you choose. Automated. They never see your wallet. You never trust a custodian.
Up to 10 schedules per recipient. Periods from 1 day to 365 days. Pause, change, or cancel any time. Available to Premium plans.
- 04
When you're gone, your family inherits together
Your named recipients claim their share with a built-in cooling-off period and a quorum signature. No single person can act alone.
20-minute commit-reveal window prevents frontrunning. Pull-only withdrawal prevents reentrancy. Pro-rata distribution by share. Recovery available throughout.
Five steps. About ten minutes.
You spend most of it deciding the rules. The wallet interaction at the end is short — and the wizard refuses to advance if the shares don't sum exactly to 10,000.
- 01 · Chain
Pick one of nine. EVM × 7, Bitcoin, Solana, Tron. The contract behaviour is identical across them.
- 02 · Cadence
How often you check in: 30, 90, or 180 days. Change it any day, only your signed transaction takes effect.
- 03 · Heirs and shares
Add up to dozens of recipients. Shares in basis points so they always sum to 10,000.
- 04 · Guardians
Optional. Trusted contacts who can extend the deadline if you're travelling, never withdraw funds.
- 05 · Deploy
One transaction creates the vault contract from your wallet. We don't see it. We don't touch it.
In plain English, with the math underneath.
Most crypto products lead with technical proofs. We lead with the promises those proofs are there to keep.
- 01
Your assets stay yours.
OwnershipYour crypto sits in a vault that only your wallet can change. We have no key. No admin button. No way to move your funds. Ever.
Like a safe-deposit box where the bank holds the room, you hold the only key. Except here, even the room is yours.
- Open-source contracts (MIT). Read every line.
- Audited end-to-end by OpenZeppelin
- Verifiable bytecode on every chain
- No upgrade backdoor for HeirVault
- 02
Your plan can't be hijacked.
IntegrityOnce you set the rules (who inherits, when, how much), nobody can rewrite them. Not us. Not a hacker. Not one family member alone.
Like a sealed will at a notary. The terms are visible, but the seal is mathematical.
- 51 formal proofs (Halmos symbolic execution)
- 10,000-run fuzz tests · 512-run invariants
- Commit-reveal anti-frontrunning on every claim
- Family quorum (M-of-N) required for inheritance

There's always a way back.
ReversibilityLose your phone, change your mind, or just want to pause? You can. There is no scenario where one bad day costs you your estate.
Like a fire alarm with a 7-day cancel window. Pulling it doesn't burn the building down.
- Account recovery: guardian-gated, 7-day cancel window
- Pause the vault any day; auto-resume after 7 days
- Cancel a claim during the 20-minute reveal window
- Override guardians with heir consensus if needed
You can lose the walletand still come back.
The first question most people ask is also the right one: "What happens if I lose my wallet tomorrow?" Here is the answer, end to end.
Recovery is gated by people you choose. It runs on a seven-day clock. You can cancel it at any point during that window. We never hold a key, never approve a recovery on our own, and never can.
See the contract that enforces this →- Day 0
You realize.
Lost phone. Stolen wallet. Forgotten passphrase. Whatever it is, you tell us and your guardians from any device, any country.
- Days 1–3
Your guardians sign.
The trusted people you named at setup confirm it's really you. They sign with their own wallets. We don't have keys to anything.
- Days 1–7
You can cancel.
Even after guardians sign, the seven-day window is yours. Pull the alarm, change your mind, anything. We default to slow.
- Day 7
Access restored.
If nothing was cancelled, your vault is now controlled by your new wallet. Heirs, rules, balances. All preserved exactly.
- Guardian-gated
- Recovery only proceeds with your chosen guardians' signatures.
- Owner-cancellable
- You can cancel during the entire 7-day window. Bad day, no problem.
- Heir-overridable
- In the rare case of guardian collusion, your heirs can reset stewards together.
What can happen.And what cannot.
Trust is built when fears are named, not avoided. Here is the shortest list we could write of every scenario that could matter to you.
- Pause the vault any day, for any reason.
- Change heirs, shares, and stewards while you're alive.
- Cancel a claim during the 20-minute reveal window.
- Reset stewards (your trusted extenders) with heir consensus.
- Recover access to the vault if you lose your wallet (7-day window, you can cancel).
- Cancel all standing orders in a single transaction.
- Move chains. Use 1 chain or 9. The plan stays the same.
- Move your funds. Ever.
- Change your heirs, shares, or rules.
- Force a claim. Force a recovery. Force anything.
- See your seed phrase. We don't have it.
- Disappear and take your assets with us. The vault is yours, on-chain.
- A single heir cannot claim alone. Your family quorum is required.
- A hacker who takes one wallet cannot drain the vault.
- A steward cannot take time away from you, only grant more.
- A bug-bounty researcher can only earn rewards, never reach your funds.
- A court order cannot make us hand over keys. We don't have any.
