Underlying these compliance pressures are structural characteristics of crypto markets that make regulatory reporting uniquely difficult:
Data ingestion & normalization
Multiple venues and protocols generate inconsistent formats that require continuous maintenance and transformation.
Valuation
Crypto trades 24/7 with no closing price, fragmented liquidity across venues, and frequent idiosyncratic market movements. Traditional pricing shortcuts (such as VWAP or simple averages) often fall short of the fair-value expectations needed for compliant reporting, particularly for crypto-to-crypto transactions. While CARF and other tax requirements do not necessarily require an IFRS or US GAAP valuation approach, they do require rigour and transparency. This can suggest that the longstanding guidance from accounting standards, if well applied, is an invaluable approach.
Scalability
CARF reporting may require processing hundreds of millions of transactions and serving millions of customers – volumes that exceed the design limits of many legacy systems.
Controls and governance
Regulators expect strong operational controls, audit trails, and data lineage that match or exceed the standards used for traditional financial instruments.
Classification
Asset classification and transaction classification must be complete, accurate, and consistent. Misclassifying even a small percentage of transactions can distort gross-proceeds reporting, cost-basis calculations, and jurisdictional assignments.
Many institutions initially attempt to manage CARF reporting using existing tools or spreadsheets. In practice, these approaches rarely scale. They struggle with the complexity of smart-contract behavior, lack the governance and lineage required for audit defensibility, and cannot reliably unify data across dozens of heterogeneous sources. They also fail to account for the wide range of traits, attributes, and terms and conditions that define digital assets. Simply knowing an asset’s name is not enough; tokens with similar names may function differently, carry unique rights or restrictions, or fall into different regulatory scopes. Correct classification requires structured reference data and a deep understanding of how each asset actually behaves.
CARF ultimately exposes a foundational truth: digital-asset reporting requires purpose-built infrastructure capable of handling the unique characteristics of blockchain-based financial data.
