## About

Open Custody Protocol operates a multi-jurisdictional structure spanning Menlo Park, Grand Cayman, Hong Kong, Tortola and London. The entity focuses on non-custodial digital-asset infrastructure, building open-source smart-contract frameworks that allow institutions to hold and settle crypto assets without relying on a centralized third party. Its core innovation is a protocol-level custody model that separates asset control from balance-sheet risk — a direct response to the exchange failures of 2022. The protocol typically supports institutional workflows including multi-signature governance, programmatic settlement and on-chain policy enforcement. Its architecture is designed for integration by asset managers, family offices and financial institutions seeking to self-custody digital assets while maintaining operational and regulatory controls. The open-source nature of the codebase distinguishes it from proprietary custody software like Fireblocks or BitGo, making audibility and composability central to the deployment model. Geographic coverage spans the US, Caribbean, Asia and Europe, reflecting the distributed user base of the protocol's institutional adopters. The entity maintains a lean operational footprint consistent with a protocol-development organization rather than a regulated custodian or asset manager. Team size and total capital deployed are not publicly disclosed. No dedicated investment vehicle, family-office structure or philanthropic foundation has been identified as linked to the protocol's core development entity. Public records indicate operational activity across multiple offshore jurisdictions, which is typical for open-source crypto infrastructure projects seeking jurisdictional flexibility. What structurally separates Open Custody Protocol is its reliance on protocol-native enforcement over institutional trust. Unlike centralized custodians that hold assets on behalf of clients under a licensed trust structure, this protocol eliminates the custodian intermediary entirely. Adopters run the open-source software to interact directly with smart contracts, with settlement rights determined by on-chain credentials rather than by a corporate entity's internal ledger. This makes the architecture a form of autonomous financial infrastructure — a departure from both traditional custody and the SaaS-based crypto-custody model.

## Questions

### What exactly is Open Custody Protocol's core product?

The protocol provides an open-source smart-contract framework for non-custodial digital-asset holding and settlement. Institutions deploy the software to retain direct control of private keys rather than depositing assets with a centralized custodian. This approach replaces balance-sheet trust with on-chain enforcement, using multi-signature governance and programmable policy controls embedded in smart contracts.

### Why does Open Custody Protocol maintain entities in multiple offshore jurisdictions?

Multi-jurisdictional structuring is common among open-source crypto infrastructure projects and reflects operational and legal flexibility rather than a conventional office footprint. Locations such as the Cayman Islands and the British Virgin Islands offer established frameworks for digital-asset operations, while Hong Kong and London provide access to institutional markets in Asia and Europe.
