Separate digital-asset custody approval from signing execution
Which people, services, thresholds, and key stores may authorize each class of asset movement?
Operational pain
Wallet systems often collapse business approval, key access, and transaction signing into one privileged path, enlarging the blast radius of operator or service compromise.
Trigger
Launch of institutional custody, a new chain integration, or a key-control finding.
QNSI contribution
Connect the decision to a controlled security path
Represent signing policies, key identifiers, service identities, and auditable authorization events in QNSI while preserving the customer's custody boundary.
Decision artifact
An asset-tier signing policy matrix and evidence trail that distinguishes approval from cryptographic execution.
What still requires validation
The custodian must validate chain semantics, quorum enforcement, transaction pre-execution checks, hardware execution, and legal custody controls.
External problem context
Primary sources
These sources establish the external requirement or risk context. They do not endorse HEOSSI or prove that QNSI completed this scenario.
Evidence boundary
What this page does—and does not—prove
This is a product evaluation pattern, not a customer case study, certification, legal opinion, regulator endorsement, or claim that a production deployment completed the described work.
