01Overview

A reusable identity wallet: one verified check, shared as a signed attestation carrying only the fields the other side needs.

02The problem

Customers of a brokerage group verified themselves separately for each licensed entity, uploading the same documents four times. Copies of identity papers accumulated in four systems, and every duplicate was a liability nobody wanted to hold.

03What we built
01

Verify once, properly

Document authenticity, liveness and screening run once to a standard every entity accepts, with the underlying documents held in a single vault.

02

Share fields, not files

The customer approves a named set of attributes. The requester receives a signed attestation and never receives the documents at all.

03

Dated and revocable

Every attestation carries a validity period and can be revoked, so a stale check expires instead of quietly ageing inside someone's database.

04The result

Onboarding an existing customer to a second entity fell from days to seconds, and redundant document stores were decommissioned.
