Code Audits
OpSec Audit
Your protocol is only as secure as its operations. We harden key management, access controls, multisig governance, CI/CD secrets, and admin workflows so real-world attacks don’t reach production.

We turn incentive design into measurable protocol performance. Instead of theorizing, we size economic leakages, expose profit-seeking deviations, and deliver parameter updates that improve depth, stability, and user fairness.
What is an OpSec Audit?
An OpSec audit reviews the people, keys, and processes that run your protocol day-to-day. We examine key custody, multisig governance, signer devices, release workflows, emergency procedures, node and RPC access, and third-party integrations. The goal is simple: close the operational gaps attackers actually use.
Why an OpSec Audit Matters
Blockchain losses are often operational: rushed admin actions, weak signer hygiene, or brittle release steps.
A single mistake can mean:
Unrecoverable financial loss
Reputational damage
Compliance and listing friction
Our OpSec audit services surface and fix weaknesses in keys, roles, and pipelines ahead of time, so your organization can trust its operational backbone from staging to mainnet.
Our Approach to OpSec Audit Security
Choosing the right OpSec audit partner isn’t about a PDF, it’s about protecting how your team actually ships software. We harden key management, access controls, CI/CD, and admin workflows so real attacks don’t reach production. Every engagement maps real attack paths, ranks risk by impact, and delivers minimal-change fixes your team can merge quickly.
Each Three Sigma audit is tailored to your needs, architecture, ecosystem. Our OpSec audit delivers practical, minimal-change fixes that make operations safer, faster, and easier to maintain.Whether your project runs on:
We account for signer devices and key management (HSM/HW, backups, recovery), multisig policy and timelocks, SSO/MFA and RBAC, vendor access, and release/rollback workflows.
Common OpSec Vulnerabilities
Key leakage / unintended signer use
Compromised seeds, lax backups, or shared devices let attackers (or insiders) initiate admin actions. Poor recovery hygiene turns a small mistake into irreversible fund movement.
Over-privileged roles / stale access
Wildcard IAM, shared accounts, and forgotten service users expand “routes to power.” Lack of MFA/SSO and weak rotation policies make abuse cheap and hard to detect.
Weak multisig policy / signer overlap
Too few signers, no timelock, or the same people on multiple multisigs collapses real separation of duties. Emergency keys without controls become a single point of failure.
Secrets sprawl in CI/CD
Tokens and private keys leak via runners, logs, or artifact stores. Unpinned dependencies and missing provenance/SBOM invite supply-chain injection during build or release.
Blind signing / unsafe admin UX
Signers approve opaque payloads without human-readable previews or dry-runs. One wrong click pushes upgrades, pauses, or parameter changes straight to mainnet.
Fragile release & rollback
No four-eyes on deploys, missing canaries, or untested rollback paths make hotfixes risky. Break-glass paths exist, but no one knows the steps under pressure.
Vendor & bot overreach
Third-party tools, webhooks, and OAuth scopes gain production-level permissions. Poor review of integrations lets external incidents cascade into your environment.
Monitoring gaps / alert fatigue
Critical actions (mint, pause, upgrade, signer change) aren’t monitored—or alerts are so noisy they’re ignored. Incidents go unnoticed until users report loss.
Insufficient incident readiness
No runbooks, no comms plan, and no regular drills. When something breaks, teams debate ownership instead of executing halt, revoke, rotate, and recover.
OpSec audits consistently uncover small operational gaps that become big attack paths: weak keys, excess permissions, brittle releases, and unmonitored admin actions.
Our OpSec Audit Process
Scoping & Planning
Define critical assets, roles, and high-impact actions, align scope, assumptions, and success criteria.
Architecture Review
Map trust boundaries and routes to authority across people, processes, and systems, document dependencies and change controls.
Testing & Readiness Exercises
Evaluate access, secrets, key handling, environments, and third-party integrations against least-privilege and good-practice baselines.
Run targeted checks and dry-runs to validate sensitive actions, release safety, and incident response readiness.
Findings & Recommendations
Deliver severity-ranked issues with owners and clear, minimal-change remediation guidance for code, config, and procedures.
Verification
Confirm implemented fixes, re-check risky paths, and issue a concise confirmation of status.

Frequently Asked Questions
Check out the OpSec Audit F.A.Q.
What is included in an OpSec audit?
A review of key custody, access control (SSO/MFA/RBAC), multisig governance, CI/CD and secrets handling, admin workflows, third-party integrations, monitoring, and incident readiness. Scope adapts to your stack.
Do you need production access or private keys?
No. We never require private keys. For production, we rely on evidence (configs/logs) and controlled screen-shares. When hands-on validation is useful, we use staging or test environments.
How do you handle sensitive data?
Evidence is compartmentalized, stored securely, and retained only as long as required for the audit and verification. We can work under your NDA or provide ours.
How is success measured?
Reduced routes-to-power, fewer over-privileged roles, stronger key handling, verified sign-UX, rehearsed incident procedures, and a clear owner for every high-impact action.
How often should we repeat an OpSec audit?
After major releases or org changes (new signers, custody model, vendors). Many teams schedule a refresh quarterly or bi-annually.
