Institutional digital-asset custody

Where institutions hold what matters.

Regulated, insured, fully segregated custody for digital assets, with the governance, controls, and reporting that treasuries, funds, and exchanges are held to.

SOC 2 Type II · Segregated cold storage · Comprehensive insurance

Segregation

Assets segregated, never commingled.

Every client holds bankruptcy-remote, individually segregated wallets with continuous on-chain proof of reserves. What's yours stays demonstrably yours.

✓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

✓REST & webhook API for transfers, policy, and reconciliation
✓Real-time statements and immutable, exportable audit trails
