The client is an institutional/corporate team that needs to manage large assets and cannot be held by a single person holding the private key. Requires multi-party approvals, hierarchical authority, and traceable audits of all operations.

The challenge is not in the multi-signing contract itself (mature solutions already exist), but in the enterprise-level management process—approval flow, role permissions, operation logs, email/SMS notifications, compliance audit interfaces—forming a complete closed loop.
