Auditing Digital Assets: Evidence, Existence, Valuation and Revenue Challenges in Crypto-Holding and Trading Entities A Practitioner's Perspective

Abstract

The rapid growth of entities that hold, trade and earn revenue from crypto-assets has outpaced the development of auditing guidance tailored to this environment. Digital assets have moved decisively from the margins of finance into the balance sheets of regulated funds, market makers, fintechs and conventional corporates, with the global crypto-asset market now measured in the trillions of dollars. Auditors are now routinely asked to express opinions on financial statements that include digital assets, yet the established toolkit of external confirmations, period-end cutoff procedures and observable market prices maps poorly onto blockchain-based holdings and continuous, automated trading. This paper sets out, from a practitioner's standpoint, the principal challenges encountered when auditing crypto-holding and trading entities: establishing the existence and ownership of on-chain assets; obtaining assurance over the completeness of an entity's wallet population; valuing illiquid tokens, liquidity-pool positions, non-fungible tokens and stablecoins; auditing emerging instruments such as token loan agreements, warrants and forfeitures; addressing cutoff in markets that never close; and testing revenue arising from market-making, arbitrage and staking. For each area, the paper describes how the profession currently adapts existing standards-notably ISA 500, ISA 501, ISA 540 (Revised), ISA 240, IFRS 13 and the recently effective FASB ASC 350-60-and where meaningful gaps remain. The paper argues that strengthening audit practice in this domain is not a narrow technical concern but a matter of investor protection and financial-system integrity, given the scale of value now held in digital form and the heightened fraud and money-laundering risks that accompany it. It concludes with practical considerations for auditors and a call for more specific standard-setting and practitioner guidance.
