01Overview

Institutional custody where every withdrawal needs a quorum, a whitelist and a time lock, and no single person can move anything.

02The problem

The desk held client assets in a wallet controlled by two people and a shared password manager. Approvals happened on a phone call, transaction policy existed as a document, and an auditor had no way to test either.

03What we built
01

Policy in hardware, not in a memo

Limits, whitelists and time locks are enforced by the signing devices themselves, so a policy cannot be talked around at eleven at night.

02

A quorum by role

Approvals are bound to roles (operations, treasury, risk, compliance) with separation of duties enforced technically rather than by trust.

03

Recovery rehearsed, not assumed

The key ceremony, backups and recovery path were documented and rehearsed with the client twice before a single asset moved.

04The result

The desk passed its licensing review using control evidence the system produces itself, and now onboards institutions that had previously refused it on custody grounds.
