The Digital Asset Inventory and Audit Act of 2026 requires federal agencies to identify, secure, and audit any cryptocurrencies and digital assets they seize or maintain in their custody. Within 180 days of the bill's enactment, the Attorney General must issue binding directives requiring all federal agencies to scan any digital devices or electronic information they collect for cryptocurrency private keys and wallet materials, then properly secure these assets and conduct annual audits to track and document them. The bill establishes technical standards for scanning and storing digital assets, requires agencies to submit annual audit reports to Congress and the Attorney General, and mandates the Government Accountability Office to review federal compliance every three years. The legislation affects all federal law enforcement, intelligence, and regulatory agencies that handle digital evidence, and funds the digital forensic tools needed to implement these requirements through existing federal asset forfeiture funds.
