Products / Qualified Custody

Institutional custody, engineered for control

MPC key management, segregated and insured holdings, and governance policies that put every movement of funds under your rules.

Why Coinsonnet

Security you can show your auditors

MPC key management

Keys exist only as distributed shares — no single point of compromise, no seed phrase in a drawer.

Segregated & insured

Assets held in your name, bankruptcy-remote from ours, with insurance coverage on custodied funds.

Proof of reserves

Routine third-party attestations that what we hold matches what the ledger says.

Capabilities

Control at every layer

Governance policies

Quorums, limits, time-locks, and velocity rules — composed per vault.

Address allowlists

Funds can only move to destinations your administrators have approved.

Isolated signing

Transaction signing in hardware-isolated environments with deterministic builds.

Complete audit trail

Every action — who, what, when, from where — immutably logged and exportable.

Disaster recovery

Tested key-share recovery procedures, so operational mistakes are never fatal.

24/7 monitoring

Anomaly detection on every withdrawal pattern, with human escalation.

Custody worth the name
