Our Blockchain Audit Methodology

A statutory audit is more than a compliance exercise. It is an independent assessment of whether an organisation's financial statements present a true and fair view in accordance with the applicable financial reporting framework.

For Crypto-Asset Service Providers (CASPs) and blockchain businesses, the audit process requires an understanding of digital assets, blockchain technology, custody arrangements, governance frameworks and financial reporting principles. While the objectives of the audit remain consistent across all industries, the procedures performed are tailored to reflect the unique risks associated with digital asset businesses.

At CYAUSE Audit Services, we apply a structured, risk-based audit methodology that combines the requirements of International Standards on Auditing (ISA) with specialist knowledge of blockchain technology, digital asset accounting and the evolving regulatory environment.

Our objective is to deliver an efficient, high-quality statutory audit while minimising disruption to your business and maintaining complete independence throughout the engagement.

Every audit engagement is guided by five core principles:

These principles underpin every stage of the engagement and ensure that our work complies with professional standards while providing meaningful assurance to shareholders and other stakeholders.

Before substantive audit work begins, we develop a comprehensive understanding of your organisation.

This includes gaining knowledge of:

For blockchain businesses, understanding how digital assets flow through the organisation is essential in designing appropriate audit procedures.

International Standards on Auditing require auditors to identify and assess the risks of material misstatement.

Our risk assessment considers factors such as:

The results of this assessment determine the nature, timing and extent of audit procedures.

A statutory audit includes obtaining an understanding of internal controls relevant to financial reporting.

Depending upon the organisation, this may include consideration of:

Understanding these controls assists in designing appropriate audit procedures.

Substantive procedures provide evidence supporting the amounts and disclosures presented within the financial statements.

Depending upon the business, procedures may include:

• examining accounting records;
• reviewing supporting documentation;
• testing transactions;
• analytical procedures;
• confirmation procedures;
• evaluating estimates;
• reviewing contracts;
• examining blockchain transaction evidence where relevant;
• reviewing reconciliations; and
• assessing financial statement disclosures.

Every procedure is designed to obtain sufficient and appropriate audit evidence in accordance with International Standards on Auditing.

Where organisations hold or administer crypto-assets, additional procedures may be appropriate.

These may include consideration of:

The precise procedures performed depend on the entity's operations and the assessed audit risks.

Towards the conclusion of the audit, we perform procedures designed to ensure that all significant matters have been appropriately addressed.

These include:

Completion procedures support the formation of the auditor's opinion.

Upon completion of the audit, we issue our independent auditor's report in accordance with International Standards on Auditing.

Where appropriate, we also communicate with those charged with governance regarding matters such as:

• significant accounting judgements;
• audit observations;
• internal control deficiencies identified during the audit;
• uncorrected misstatements;
• significant audit risks;
• qualitative aspects of accounting practices; and
• other matters required by professional standards.

Our objective is to provide clear, constructive communication while maintaining auditor independence.

Our audit methodology incorporates secure digital collaboration tools that facilitate efficient communication throughout the engagement.

Clients benefit from:

• secure document exchange;
• organised information requests;
• real-time progress monitoring;
• reduced administrative burden;
• improved audit coordination; and
• timely communication between management and the audit team.

This enables the audit to progress efficiently while protecting confidential information.

Effective communication is essential to a successful audit.

Throughout the engagement we maintain regular dialogue with management regarding:

Early communication helps avoid unnecessary delays and supports efficient completion of the audit.

Blockchain businesses require auditors who understand both traditional financial reporting and emerging digital asset technologies.

Our methodology is specifically designed to address:

Rather than applying a generic audit programme, we tailor our procedures to reflect the specific characteristics of each engagement.

Every Crypto-Asset Service Provider is different, but every statutory audit should be founded on the same principles of independence, professional scepticism and technical excellence.

Our structured audit methodology enables us to deliver independent assurance that reflects both the requirements of International Standards on Auditing and the operational realities of blockchain businesses. By combining specialist industry knowledge with a disciplined audit process, we help organisations produce reliable financial statements while strengthening confidence among shareholders, regulators, lenders and other stakeholders.
