A decentralized identity wallet that generates zero-knowledge proofs and exchanges signed cards face to face

Revolution begins at the periphery

Privacy is not a feature. Privacy is hygiene. An identity system that doesn't enforce privacy at the base layer is a surveillance tool with a friendlier interface.

We stand against singular top-down mechanisms and the Pursuit of Global Consensus

You shouldn't have to register with an authority to own a digital identity. Your phone is enough. The person in front of you is enough.

Designed for Real Life

Works offline. Works without permission. Works without a login screen. Each piece composes with the rest, so communities grow on their own terms, not a platform's.

Building Blocks of Digital Trust

Six pieces. Each works alone. All compose together. Identity, contacts, and proofs stay on your device, on your terms.

Contact Graph

Every card you receive is signed with the sender's key. A verifiable edge in your social graph, one face-to-face encounter at a time.

Identity

A self-sovereign DID, guarded by Face ID. You create it, you present it, you rotate it. No vendor, no gatekeeper, no recovery email.

Proximity

Discovery over Bluetooth, QR, and AirDrop. No server in between, no login screen first. The person in front of you is the network.

Ichigo-Ichie

A 140-character note from both sides, at the moment you met. Not a chat. Not a feed. A digital memento of that day, that place, that encounter.

Selective Disclosure

Per-field control over what every person sees. Share only what matters for this encounter. The passport stays in your pocket.

ZK Proofs

Group membership and attribute claims via zero-knowledge proofs. Prove you belong, prove you are over 18, prove anything true while revealing nothing else.
