YOU SET
THE RULES.

Vault key: Protected withdrawals need your vault key. Access to your wallet alone is not enough.
Daily allowance: Spent by your wallet alone and not quantum protected. Set it to 0 to require a post-quantum signature for every withdrawal.

BUILT INTO
EVERY APPROVAL.

Each part of the approval has a job.

Approve the exact transfer

Your signature binds the amount, recipient, vault, and network. Changing those details invalidates the approval. The Solana program checks the signature and vault state before moving SOL.

How verification works

Keep your key encrypted on your device

Your vault key is stored encrypted on your phone or in your browser, protected by a supported passkey or passphrase. The phone relay carries requests and signatures; it does not receive your recovery seed.

Phone mode adds a separate screen for reviewing each request. Browser mode keeps approvals on your computer.

Choose your signing device

A fresh key for each protected action

Vaultum uses hash-based, one-time signatures. Your signer records each approved action, and the program checks the next expected key. Each tree provides 254 protected actions, with separate keys for setup and rotation.

Keys & rotation

Recovery stays in your hands

Your 24-word Vaultum phrase restores your vault keys when you replace a device. Keep an offline backup, restore in the original signing mode, and use one active signer per vault.
