Custodian Attestation of Assets Backing USDv: March 2026
Improving the transparency of USDv’s backing assets via attestation reporting for reserve assets associated with USDv.
Publication Date: 20 March 2026
Snapshot Time: 1 March 2026, 23:59 UTC
As Solomon moves toward broader availability of USDv, we are initiating monthly attestation reporting for reserve assets associated with USDv.
USDv is managed with the objective of maintaining full asset backing. This report provides point-in-time disclosure regarding a defined portion of those reserve assets, specifically assets held off-exchange within institutional custody.
At the snapshot time, Ceffu attested that specified assets were present within its institutional custody environment. This report is intended to improve transparency around the custody component of USDv’s reserve structure.
USDv’s reserve assets may also include other components of the system, including exchange balances associated with hedged positions and onchain program balances. Those components are not fully captured by this custodial attestation alone. A broader view of system balances is available on our stats page.
This report should be read as a limited, point-in-time confirmation relating only to the assets and custody environment covered by the underlying attestation. It is not a full reserve report, financial statement audit, or comprehensive reconciliation of all system assets, liabilities, income, or exposures.
Scope of a custodial attestation
A custodial attestation is a point-in-time confirmation of balances held in specified custody accounts. It reflects the value of assets present within the covered custody environment as of the stated snapshot time.
A custodial attestation does not, by itself, represent the full economic position of the USDv system. Depending on system activity at the time of measurement, it may exclude exchange balances, unrealized profit and loss on derivatives, funding accruals, executed but not yet settled activity, trading fees, and certain onchain balances.
Accordingly, custodial attestations are one component of reserve transparency, but should not be interpreted on a standalone basis as a complete statement of total reserves or overall system value.
Transparency commitment
Solomon intends to expand the scope of these disclosures over time in order to provide a broader and more complete view of USDv’s backing.
That work includes incorporating additional reserve components, including relevant onchain balances and other system balances, together with third-party confirmations where applicable. Our objective is to make the reserve structure supporting USDv increasingly transparent, reviewable, and independently verifiable.
