Crypto Asset Disclosure Notes: What the Financial Statements Must Say

Recognising crypto correctly is only half the job. The notes are the other half — and FASB ASU 2023-08 added specific crypto disclosures, IFRS requires policy and fair-value-hierarchy disclosure, and users expect holdings, custody, and risk transparency. This guide is the disclosure set, hedged, because the exact package is a framework-specific auditor judgement.

TL;DR

• Crypto is volatile, often material, judgementally measured → users need what is held, how measured, and the risks.
• FASB ASU 2023-08 added specific crypto disclosures alongside fair value + the 2026 FASB separate balance-sheet line.
• IFRS requires the accounting policy and, where fair value is used, the IFRS 13 hierarchy level, technique, and L2/L3 inputs, plus significant judgements.
• Custody and risk context is increasingly expected (some required, some good practice).
• IFRS ≠ US GAAP disclosure — a dual-reporting group satisfies both.
• Exact package framework-/materiality-specific, auditor-confirmed. Not a fixed template; not accounting advice.

Why specific disclosures

Crypto is volatile, often material, and measured under judgemental policies, so users need to understand what is held, how it is measured, and the risks. ASU 2023-08 introduced specific crypto disclosures alongside the fair-value move; IFRS requires the accounting policy and, where fair value applies, the fair-value hierarchy. The exact package is framework-specific and an auditor judgement, not a generic template.

What ASU 2023-08 disclosure covers

Broadly, for in-scope crypto, ASU 2023-08 added disclosures around the holdings and their fair value, including information helping users understand the holdings and the period's changes, consistent with fair value through net income and the separate balance-sheet presentation (2026 FASB taxonomy). The precise line items/granularity are set by the standard and read from it with the auditor — not enumerated here as a fixed checklist (anti-fabrication discipline).

What IFRS disclosure covers

At minimum: the accounting policy (IAS 38 cost/revaluation, or IAS 2); where fair value is measured, the IFRS 13 hierarchy level, valuation technique, and L2/L3 significant inputs; and significant judgements in classification/measurement. The specific IFRS set depends on the standards applied, auditor-confirmed.

Custody and risk context

Users increasingly expect transparency on how crypto is held (self-custody vs third-party custodian) and related risks (volatility, concentration, key/operational). Depending on framework and materiality, some is required, some good practice. Disclosure is not only the balance-sheet number but the context a reader needs — a framework-/materiality-specific auditor judgement.

IFRS and US GAAP differ

Measurement bases differ (IAS 38 vs ASU 2023-08), so disclosures differ; a dual-reporting group satisfies each framework's requirements (see crypto CoA GAAP/IFRS mapping). The categories are similar in spirit; the specific required disclosures follow the entity's actual framework, auditor-confirmed.

Practical guidance

1. Treat disclosure as half the job — recognition is not enough.
2. Read ASU 2023-08 disclosures from the standard with the auditor — no fixed checklist assumed.
3. Disclose the IFRS policy + hierarchy level + judgements where applicable.
4. Add custody/risk context per framework and materiality.
5. Satisfy both frameworks if dual-reporting — disclosures aren't shared.
6. Confirm the required package with your auditor — framework-/materiality-specific; not accounting advice.

How vendor tools handle disclosure

Cryptio and Bitwave produce holdings, movement, and fair-value reports that feed the disclosure notes. Confirm the tool can produce per-period holdings/changes, hierarchy data, and custody information — the tool feeds the disclosures; what must be disclosed is an auditor judgement under the applicable standards.

How Wag3s helps

Wag3s Ledger produces per-period holdings, movements, fair-value and custody data with an audit trail, feeding the crypto disclosure notes under IFRS or US GAAP — while the required disclosure package stays auditor-confirmed per the applicable framework. See the Ledger product page.
