Map the system
Agree the code versions, architecture, supported technologies and operational perimeter.
Blockchain security
Examine the trust beneath the transaction.
Security review of blockchain systems, smart-contract assumptions and the operational controls surrounding digital assets.
Discuss your needsA blockchain application is more than its contract code. Key management, administrative powers, signing processes, front ends and external dependencies all influence what users are actually trusting.
We examine the boundaries of that trust. What can a privileged role change? Which components can halt or redirect an operation? What assumptions are being made about inputs, counterparties and recovery?
The scope is agreed around the technology and expertise required. Findings are explained in terms of exploitable conditions, practical impact and remediation. A review cannot guarantee that a system will never be compromised, but it can make its assumptions and weaknesses much clearer.
The questions we address
- Which trust assumptions does the design rely on?
- How are privileged actions and signing rights controlled?
- What happens if an external dependency behaves unexpectedly?
- Which failure scenarios have the greatest operational impact?
What you take away
- A map of trust boundaries and privileged roles
- A scoped technical security assessment
- Prioritised findings and design recommendations
- A restitution of residual risks and review limitations
How the engagement unfolds
Examine the assumptions
Review trust boundaries, privileged behaviour and credible failure scenarios.
Clarify the residual risk
Explain findings, recommended corrections and what falls outside the reviewed scope.
Questions before we begin
Does the review cover every blockchain?
The supported technology, contract language and depth of analysis are confirmed before accepting an engagement. A scope should match the expertise required.
Does an audit guarantee that a protocol is secure?
No. An assessment is bounded by its scope, version, methods and timing. The report should make those limits explicit and explain the remaining risks.
Can you review custody and operational processes?
Yes, these can be included in a defined scope alongside technical review. Signing rights, access, recovery and change control are often central to the risk.
