Identify control gaps before funds move. Six questions tailored to your operating model and transaction risk profile.

Step 1 of 6
Question 1

What is a crypto attack surface assessment?

A crypto attack surface assessment is a structured review of the control gaps in a digital asset organisation's transaction lifecycle — from the moment a counterparty wallet is first encountered to the point at which funds are confirmed on-chain.

Unlike a traditional penetration test or compliance audit, it focuses on operational and policy-level exposure: where controls are absent, partial, or dependent on a single point of failure. For centralised exchanges, custodians, payments processors, and infrastructure providers, the highest-impact risks often sit not in infrastructure vulnerabilities, but in the decision logic applied before a transaction is signed or broadcast.

Why pre-execution controls matter more than post-transaction monitoring

Most security tooling in digital asset markets focuses on detecting suspicious activity after it has occurred. By the time a transaction is flagged post-broadcast, funds may already be irreversible. Pre-execution enforcement — policies applied before a transaction is signed or sent — is the control category with the highest potential for loss prevention, and the one most commonly absent or only partially implemented.

Who should complete this assessment?

This assessment is designed for operators in regulated or high-value digital asset environments: centrally-custodied exchanges, institutional custodians, on-ramp and off-ramp payments processors, stablecoin issuers, and infrastructure providers with direct exposure to transaction flows. It is particularly relevant for security leads, compliance officers, and operational risk managers evaluating current control coverage.

Frequently asked questions

How long does the assessment take?
Six questions, typically two to three minutes. Each question is weighted based on your operating model and focuses on the control areas most material to your risk profile.
What does the result include?
Your result includes an indicative exposure band, a control maturity score, and observations across five areas: wallet handling, pre-execution enforcement, allowlist governance, provider dependency, and chain and asset coverage. A full written report is available on request.
Is this a formal security audit?
No. This assessment is indicative and based on self-reported responses. It is designed to surface potential control gaps and does not constitute a formal audit, legal opinion, security guarantee, or certification of regulatory compliance. It serves as a starting point for a more detailed review.
Is this relevant for MiCA compliance?
The assessment covers several control areas relevant to MiCA and broader regulatory frameworks, including pre-transaction risk controls, ongoing monitoring, and provider dependency. It is not a compliance assessment, but the observations it generates may inform your readiness review.
