✓Per-client segregated addresses with on-chain attestation
✓Deep cold storage with geographically distributed key shards
✓Independent, real-time proof-of-reserves reporting

Security

Security that survives scrutiny.

Keys are generated and held in hardware-isolated MPC. No single person, device, or location can move funds. Every withdrawal passes policy before it passes on-chain.

✓Multi-party computation across hardened, audited infrastructure
✓Configurable approval quorums, allow-lists, and time-locks
✓SOC 2 Type II, penetration-tested, continuously monitored

Operations

Operate custody programmatically.

A single API for balances, transfers, settlement, and statements, so custody fits inside your treasury stack instead of beside it. Audit-ready exports on demand.

✓REST & webhook API for transfers, policy, and reconciliation
✓Real-time statements and immutable, exportable audit trails
✓Dedicated solutions and operations support, 24/7
