SOC 2 - Blockchain
SOC 2 for Blockchain Projects
A quick-reference notesheet for prep, vendor integration, and auditor conversations.
Key Controls (Blockchain Context)
Access Control
- Enforce RBAC on smart contract deployment, node ops, and key management.
- Multi-sig for treasury, validator, or upgrade functions.
Change Management
- Reviews of smart contract updates, forks, and governance votes.
- Versioning & rollback plans for chain code and off-chain services.
Data Security
- Encrypt wallet seeds, API keys, validator creds at rest (HSM/secure enclave).
- TLS everywhere, including RPC/API endpoints.
Monitoring & Logging
- Track validator/node uptime, forks, consensus anomalies.
- SIEM integration for exchange, custody, or bridging infra.
Incident Response
- Crisis comms for chain halts, bridge exploits, or key leaks.
- Documented chain-rollbacks / governance processes.
Common Speed Bumps
Decentralization vs. Control
Auditors expect accountability; DAOs/decentralized governance can look “ownerless” without clear control points.
Crypto Custody
Expect scrutiny of hot vs. cold wallet procedures and segregation of duties to prevent single-operator risk.
Third-Party Risk
Clarify control ownership for oracles, custodians, exchanges; attach risk assessments and monitoring.
Key Lifecycle
Formalize key rotation, recovery, and secure destruction; ad-hoc processes will be flagged.
On-chain Transparency vs. Privacy
Balance immutability with GDPR/PII obligations using off-chain storage, redaction, and data-minimization.
Quick Auditor Checklist
Formal policies for wallet/key management, smart contract updates, and chain governance.
Segregation of duties across key ops, treasury, and validator controls.
Centralized logging (nodes, APIs, custody infra) retained ≥ 1 year.
Incident playbooks (bridge exploit, validator compromise) documented and tested.
Vendor risks (custodians, exchanges, oracle feeds) assessed and monitored.
Continuous monitoring (Vanta/Drata + manual blockchain evidence) demonstrable.
