Custody where every withdrawal has a quorum

Overview

Institutional custody operations: withdrawals pass through written policies, multiple signers and time-locks, and every step is on the record.

What we designed

01
An approvals queue
Each withdrawal shows its quorum, its destination's allow-list status and what is still missing.
02
Policies as sentences
Rules read as when, and, then. The people who approve the policy can read it without an engineer.
03
Sign from the phone
A signer reviews the same details on mobile and signs with a hardware-backed key.
