Subsequent Event Review [Abstract]
Subsequent Event Review	Note 9. Subsequent Event Review On August 5, 2026, the Trust entered into a custody agreement with BitGo Bank & Trust, National Association (“BitGo”), pursuant to which BitGo serves as the second custodian for the Trust’s BNB. As of the date the financial statements were issued, the Trust had not transferred any BNB to BitGo. The Trust has evaluated subsequent events and transactions for potential recognition or disclosure through the date the financial statements were issued and has determined that there are no other material events that would require disclosure in the financial statements.

The entire disclosure for significant events or transactions that occurred after the balance sheet date through the date the financial statements were issued or the date the financial statements were available to be issued. Examples include: the sale of a capital stock issue, purchase of a business, settlement of litigation, catastrophic loss, significant foreign exchange rate changes, loans to insiders or affiliates, and transactions not in the ordinary course of business.
