Security is a design responsibility throughout the engagement. XCusty provides smart contract review and audit services alongside engineering controls for the surrounding application and infrastructure. The exact review scope, independence requirements and remediation process are established in the statement of work.
Threat modeling
We examine how assets, credentials and administrative powers could be misused. The assessment considers external attacks, compromised accounts, integration failures and mistakes by authorized users. This informs the controls that matter most for the particular system.
Contract review
Review can include privileged access, business logic, token behavior, contract interactions, external data dependencies and upgrade mechanisms. Automated analysis is combined with manual examination and tests designed around the application's actual asset flows.
Findings should explain the affected component, potential impact, recommended correction and verification status. Where an independent audit is required, it is commissioned as a distinct review with an agreed provider and scope. Inclusion of a security firm in the relationship network does not mean every XCusty project has been audited by that firm.
Application and infrastructure controls
Protection can extend to identity management, secrets storage, network access, deployment permissions, application testing and monitoring. Production access is planned around named responsibilities and the minimum permissions needed for the role. Changes to critical configuration are recorded and reviewed.
Operational readiness
Before launch, the team reviews open findings, accepted risks, incident contacts and emergency procedures. Pause or containment mechanisms are tested where they form part of the design. Recovery and escalation procedures are documented so that the client knows what to do when a technical or security event occurs.
A clear assurance boundary
A review provides evidence about a defined version and scope at a point in time. It does not eliminate every possible vulnerability or cover future changes automatically. Continued security depends on controlled releases, monitoring, maintenance and periodic reassessment as the system evolves.
