The US Treasury is developing a framework to custody the Bitcoin held by the federal government. The plan would combine self-custody and third-party custodians instead of relying on only one approach.
That may sound like back-office plumbing, and it is. But when the asset involved is somewhere between approximately 198,000 $BTC and more than 328,000 $BTC, the details matter a great deal.
What the Treasury is building
The custody effort is part of a broader push to improve the accuracy of federal agencies’ reports on their Bitcoin holdings. Washington wants to know exactly what it owns and where those assets are held.
The framework is intended to support two models. With self-custody, the government holds the private keys itself. With third-party custody, a specialized outside firm safeguards the keys on the government’s behalf.
The work is also linked to a follow-up review of agency holdings. Under the original executive order, agencies had 30 days to review and report how much Bitcoin they controlled. The new review aims to make those figures more accurate.
The Strategic Bitcoin Reserve backdrop
The effort dates back to March 6, 2025, when an executive order, EO 14233, established the Strategic Bitcoin Reserve.
The order authorizes the Treasury to manage forfeited Bitcoin and prohibits routine sales of those holdings. Sales are allowed only in limited circumstances.
The reserve comprises coins acquired mostly through civil and criminal asset forfeitures. The government obtained them through law enforcement actions, not purchases on the open market.
The size of the holdings remains unclear. Estimates range from approximately 198,000 $BTC to more than 328,000 $BTC. The difference largely depends on whether coins involved in pending litigation are included.
Cold wallets under the microscope
The custody effort comes as the industry is paying closer attention to cold wallet security. A cold wallet stores private keys offline, typically on a dedicated hardware device, to protect them from internet-based attacks.
Recent high-profile firmware issues in hardware wallets have complicated that reputation and brought custodial practices back into focus.
The Treasury initiative concerns operational custody. It has not been presented as a direct response to an outside breach.
Disclosure and acquisition questions remain open
Patrick Witt, a senior crypto policy advisor, has said discussions are ongoing about whether to disclose the government’s specific holdings publicly. No decision has been made.
Witt is also examining possible ways to acquire more Bitcoin. The options need further legal analysis before any action is taken, and there is not yet consensus on how to proceed.
The reserve currently consists of forfeited assets. Expanding it through other means would require a legal basis, which is still under study.
What this means
The ban on routine sales in EO 14233 is already significant. Historically, large government auctions of seized coins prompted concerns that supply could enter the market. A reserve that holds rather than sells changes that calculus, although the order’s limited exceptions mean sales are not entirely ruled out.
The accuracy review may prove equally consequential. Until agencies establish a reliable count, estimates ranging from approximately 198,000 $BTC to more than 328,000 $BTC are likely to persist. Pending litigation will continue to account for much of the uncertainty.
