Threat model
AI
When faces and voices can be faked, identity needs stronger proof than what shows up on a screen.
A multisig vault that only real humans can sign.
Shared Vaults. Real humans. Every approval.
Built for families, investment clubs, and DAOs who share funds. No browser extensions, no duplicate accounts. Every signer is a real, unique person, verified by World ID before each signature.
Live preview — what you'll see in World App
Built on Safe — and locked to verified humans. Signer impersonation, the most common attack class against multisigs, is blocked by design.
Built on Safe and World ID.
Safe
World ID
Why this matters now.
AI broke the old trust model. Human Vault anchors every outbound transfer to a unique, verified person — not just a device or a key.
Execution rule
Human
Deposits stay easy. Money cannot leave the Vault until each required signer passes World ID verification.
User experience
Social
The goal is simple: multisig should feel social and obvious, not like juggling browser extensions and hardware wallets.
What HumanVault changes
Instead of trusting keys alone, every signature gets paired with proof of humanity. That makes the vault infrastructure harder to socially engineer and much easier to understand.
Safe underneath.
The vault sits on Safe infrastructure, so the smart account layer stays familiar and robust.
World ID before every signature.
Every required signer re-verifies their World ID for that exact transaction — proofs cannot be reused.
Less friction for the right actions.
Anyone can deposit. Outbound transfers trigger the human checks that actually matter.
Designed for shared signers
Think of a family treasury, a startup ops wallet, or an investment club. Human Vault turns the approval loop into a clean invite, confirm, sign, and execute flow — no matter how many signers you add.
✓Invite the people you trust to share the Vault.
✓Choose how many approvals it takes to send funds.
✓Approve and sign only after identity is re-verified.
How the demo flow works.
The product demo is built around one core idea: creation feels easy, while outgoing value gets gated by verified humans at the exact moment it matters.
01
Verify and enter
You sign in with your World App wallet and verify your World ID once — this registers you on-chain so you can create or join Vaults.
02
Create the Vault
Name the Vault, pick your signers, set the threshold, and deploy — gas is sponsored.
03
Invite your signers
Each invited signer opens World App, confirms they're a real person, and joins the shared Vault.
04
Sign and execute
To send funds, each required signer confirms they're a real person, signs, and executes together. Every transfer needs a fresh check — past approvals can't be reused.
Founder context
Built by someone who already made password security mainstream.
Dan previously built PasswordBox from zero to 16 million users in 18 months, then sold it to Intel. Some of the team’s patents went on to help shape the PassKey experience used across major consumer products.

The core promise
HumanVault is positioned as the first Safe vault where every required signature comes with biometric-backed proof of humanity. That shifts multisig from “who controls the key” to “which real person is actually approving this right now.”
01More trust for treasury and shared-wallet approvals.
02Less room for deepfake-led social engineering.
03Mobile-first, native to World App — no extensions, no second account, no seed phrase to manage.
HumanVault
Make your next multisig feel human.
HUMANVAULT is privacy-first.
We use World ID to prove a signer is a real, unique human without revealing their identity.
No name, email, phone number, or identity document is needed to sign a transaction.
HumanVault is available now inside World App. Bring proof of humanity into the vault layer, keep Safe underneath, and give every signer a flow that feels obvious from the first invite to the final execution.
