🔑 Key Takeaway: Treat custodial treasury accounts like cash vaults: classify by impact and access urgency, document who can move funds, and verify every large transfer before it is irreversible.

Treasury operations security provides protocols for organizations that hold significant cryptocurrency through custodial accounts. The material covers risk classification, registration and review templates, extra controls for high-impact accounts, and step-by-step verification for large receive and send flows.

These guides assume third-party or co-managed custody rather than day-to-day protocol governance multisigs. For protocol signer operations, see Multisig for Protocols.

What is treasury operations security?

Treasury operations security is the set of controls, documents, and procedures that keep custodial holdings available when needed and hard to drain when compromised. Classification sets the control bar; registration keeps access and configuration auditable; enhanced controls raise the bar for critical balances; transaction verification reduces social-engineering and address errors on large moves.

What this framework covers

1. Classification Framework: dual impact and operational classification plus a security control matrix for approvers, MFA, and whitelist delays.
2. Registration Documents: templates for account registration, access changes, security configuration, and quarterly review.
3. Enhanced Controls for High-Risk Accounts: additional measures for High and Critical impact accounts, including MPC considerations, policy engines, and monitoring.
4. Guide: Large Cryptocurrency Transfers: receive and send protocols with address verification, test transactions, and multi-party confirmation.

Getting started

1. Classify accounts with the Classification Framework.
2. Register each account using Registration Documents.
3. Apply baseline controls from the matrix; add Enhanced Controls for High and Critical impact.
4. Follow Transaction Verification for large transfers.
