What goes in the vault
Examples, not a checklist. Create a vault and each becomes a sealed item.
Keys & wallets
The things that, lost, lose everything else.
- Seed phraseSeed phrase
A wallet recovery phrase, checked against the BIP-39 wordlist on this device.
- Hardware-wallet recoverySeed phrase
The phrase, the PIN hint and the first address you confirmed on the device.
- Exchange recoveryCredential
The account, its recovery codes and who to call, with no password in it.
- Wallet addressesInventory
Every public address you hold and what sits behind it — nothing that can spend.
- Safe and locker keysInventory
Which key opens which box, and where the spare is kept.
A cryptographic vault: sealed, authenticated, in the owner's hands.
Sealed
Your keys are made in your browser, from a passphrase and a Secret Key, or a passkey. Every item is encrypted before it leaves your device.
Authenticated
Every seal is written to an append-only chain, its head timestamped by an authority outside our control. Checkable, not asserted.
In your hands
Your export opens offline, without us, and the chain re-derives in your browser. We cannot read your vault, and you can check.
Keep. Prove. Release.
- I
Keep
Sealed in your browser before it leaves the device. What we hold is ciphertext.
- II
Prove
Every seal on an append-only chain, its head timestamped outside our control. Provable years later, without us.
- III
Release
Guardians with a delay and your veto; a gift by a link; beneficiaries under a release contract you sign and can cancel.
Your device → an append-only chain, timestamped outside our control → the people you name, on your terms.
The first vault is free.
Planned pricing in Australian dollars, from the end of the pilot; nothing is charged today. A free vault is a real vault — sealed, exportable, verifiable — never a lighter kind of safe. What the paid tiers add is capacity and care: more items, more people, the release engine for everyone you name.
