Beyond the Balance Sheet: The Complexities of Digital Asset Audits Explained

Key Takeaways 

• Digital asset audits rely on blockchain-specific evidence, including transaction hashes, blockchain explorer data, and smart contract reviews. 

• Valuation risk is elevated in digital asset audits because many assets trade across multiple exchanges, creating price variances that auditors must reconcile. 

• Blockchain networks operate 24/7, increasing cutoff and period-end risk. Auditors examine blockchain timestamps against accounting records to confirm transactions are recorded in the correct period. 

• Custody risk is a key assurance consideration. Auditors confirm that an entity controls its digital assets by tracing small, test transactions on the blockchain back to the wallet in question. 

• Regulatory developments and the SEC’s adoption of SAB 122 directly affect financial statement presentation and require auditors to continually reassess compliance and disclosure requirements. 

Introduction and Background 

Blockchain technology and the commercialization of digital assets have pushed the auditing profession to adapt fast.  Firms must adjust established assurance techniques to match the risk profiles of these technologically advanced companies and confront challenges this industry presents. 

Blockchain-Based Audit Evidence  

The biggest differences between auditing more traditional companies, such as financial institutions and retail companies, and digital asset-based companies stem from the overall technological complexities of the blockchain.  

Digital asset audits lean on more technology-enabled evidence: transaction hashes, blockchain explorer data, and smart contracts. Most blockchain transactions are publicly visible; however understanding the economic substance takes specialized blockchain expertise. Technology controls carry more weight here too. Digital asset audits require a thorough assessment of cybersecurity, access management, and wallet key storage. A gap in any of these controls can expose a company to major losses from cyberattacks.  

Companies built around smart contract execution need advanced IT-based audit procedures, since flaws in smart contract code can trigger unauthorized transactions or financial loss. Add in transaction types unique to this industry, such as staking rewards, mining, airdrops, DeFi yields, and non-fungible token (NFT) transactions. Auditors need deep blockchain knowledge and a firm grasp of the risks tied to each transaction type.  

Operations & Transactions of Digital Asset Companies 

Digital asset transactions carry elevated audit risk because of how the blockchain operates.  

Valuation Risk Runs High 

Traditional assets like publicly traded securities move within established, observable markets. Digital assets, especially lower market cap coins, sometimes move in price within hours. Digital assets can be traded across multiple trading platforms at once, widening valuation risk when prices vary between markets.  

Auditors turn to reputable pricing aggregators such as CoinGecko or CoinMarketCap to value assets at period end, but discrepancies surface when a company’s pricing source doesn’t march. Consider a low-volume, highly volatile asset trading at different prices across multiple exchanges at period end: auditors assess management’s pricing source against other reputable providers and evaluating the gap. 

The 24/7 Transaction Environment Raises Cutoff Risk 

Traditional markets close, while blockchain networks don’t. Auditors examine blockchain transactions around period end to confirm activity was accurately recorded in the correct period. 

Take a mining company that earns a block reward before year-end but doesn’t record the revenue until after, due to processing or reconciliation delays. Auditors independently check blockchain timestamps against accounting records to confirm when the income was earned and whether revenue recognition falls in the right period. 

Custody Risk Demands Direct Proof of Control 

Banks, brokerage firms, and financial institutions hold traditional assets like cash, stocks, and bonds, often with insurance and fraud protection built in. Reputable digital asset custodians offer similar protections. Self-custodied digital assets don’t carry the same safeguards.  

To verify wallet ownership, auditors require an authorized wallet owner to initiate a nominal transaction, often under one dollar, to a test wallet address that can be traced on the blockchain. This step matters: if a company can’t demonstrate wallet ownership or transfer authority, its digital assets may sit outside its control or under the control of unauthorized parties. That gap can misstate asset balances within the financial statements and compromise the safeguarding of customer assets.  

Regulatory Uncertainty & Evolution of the Digital Asset Industry 

Few sectors move as fast as digital assets. Large institutions and entire countries have adopted digital assets, pushing regulators to keep pace. 

Recent regulatory developments include MiCA in the European Union and the GENIUS Act in the United States. Both introduce new requirements around stablecoin reserves, disclosures, governance, regulatory oversight, and custody, adding compliance considerations auditors must evaluate and test. 

Audit-related codifications are shifting too. The SEC repealed of SAB 121 and adopted of SAB 122 in January 2025, changing reporting expectations for certain entities safeguarding digital assets. This shift altered accounting treatment and reporting expectations for companies holding digital assets, and with it, how auditors assess financial statement presentation.  

Digital assets will keep growing, and regulation with keep changing alongside them. Auditors covering this space need to move faster and adapt more readily than those working in mature, established industries like banking. Regulatory and accounting developments directly affect financial statement presentation and disclosure requirements, so auditors must reassess risk and adjust their methodologies as the landscape shifts. 

What This Means for Auditors 

Digital assets are gaining ground worldwide, and that growth shows no sign of slowing. This industry brings auditors new opportunities alongside challenges unlike any other sector we’ve audited. 

 As digital assets weave deeper into the global financial system, auditors need to keep sharpening their methodologies and technical capabilities to address emerging risks head-on.
