💡 Accountant's Note
Qualified cryptocurrency custodians (regulated trust companies or banks) charge institutional clients an annual fee (typically 0.05-0.50% of assets under custody, or AUC) for securely holding cryptocurrency on their behalf. Revenue is recognized monthly as the custody service is delivered over time.
Practitioner & Systems Framework
💻 ERP Architecture
Custody fee revenue is calculated monthly based on the average AUC for the period multiplied by the annual custody rate divided by 12. As AUC values fluctuate with cryptocurrency prices, the fee is variable — a rising Bitcoin price increases AUC and thus the monthly fee. The fee is invoiced monthly and posted to the accounts receivable sub-ledger per client. Custody revenue is presented as service revenue (over time performance obligation under IFRS 15). The custodian also records the client's cryptocurrency as an asset and an equal liability (similar to the exchange user balance treatment) — but only if the custodian commingles assets. Qualified custodians hold assets separately and may use off-balance-sheet treatment depending on the legal structure.
⚠️ Audit Flags
Auditors confirm the AUC at each billing date against the custodian's own asset records (which must match the clients' portfolio statements). Test the fee rate against the signed custody agreement. Assess whether AUC is correctly valued — mark-to-market pricing of the custodied assets drives the fee. Review the off-balance-sheet vs. on-balance-sheet treatment of custodied assets — the accounting differs based on whether the custodian takes legal title. Confirm regulatory licensing — cryptocurrency custodians typically require trust company or bank licensing.
