Proof of Liabilities
Definition
Proof of liabilities is evidence of everything an issuer, platform or custodian owes, set against the reserves it holds. For a token issuer the largest liability is usually the tokens themselves: every token outstanding on every chain, plus any book-entry holdings, is a claim. But other obligations matter as much, especially those that rank ahead of holders: borrowings and liquidity facilities, fees and expenses payable, taxes, and other creditors of the issuer. Crypto exchanges have used cryptographic methods, such as publishing a hashed tree of customer balances so each customer can check that their balance is included, to show completeness of customer liabilities. For tokenized securities the equivalent evidence is the transfer agent's reconciled register and the issuer's audited balance sheet. Without the liability side, a reserve figure cannot show whether holders are covered.
Why it matters
Most backing claims are made on the asset side because assets are easy to show and liabilities are not. A custodian can confirm a balance; only the issuer's complete books, reconciled to the token supply and audited, can show everything it owes. The gap matters most for issuers that are themselves the obligor, such as note and certificate issuers, and for funds with senior financing. AltStreet's YLDS review is a clear example: Figure Certificate Company reported $994,000 of GAAP equity at June 30, 2026 against $556.0 million of certificates outstanding, so small changes on either side of the balance sheet matter, and its resilience rests substantially on its parent's support. Reading liabilities, and their ranking, is what turns a reserve number into a backing judgment.
Common misconceptions
- •Tokens outstanding are not the only liabilities. Facilities, fees and other creditors count, and some rank ahead.
- •Supply on one chain is not total supply. Every recognized chain and book-entry holding is a claim.
- •A thin equity cushion is not a reserve. When an issuer's equity is small relative to its obligations, minor losses reach holders.
- •Liability proofs show inclusion, not adequacy. They must be paired with reserves and ranking.
- •Gross coverage is not net coverage. Subtract senior claims and pledged assets first.
Technical details
The liability side, itemized
Holder claims: units or tokens outstanding across all chains and book entry, at the applicable value.
Redemptions payable: accepted requests not yet paid.
Senior obligations: borrowings, liquidity facility advances and secured creditors.
Operating liabilities: accrued management, custody, administration and audit fees; taxes.
Issuer-level creditors: for notes and certificates, every other creditor of the issuing entity.
Worked coverage calculation that respects ranking
Reserves: $250.0 million of Treasury bills and cash.
Pledged: $20.0 million of bills pledged to a facility lender; available reserves $230.0 million before senior claims.
Senior claims: $18.0 million drawn on the facility (secured by the pledged bills), and $0.5 million of fees payable ranking ahead of holders.
Available to holders: $250.0 million minus $18.0 million minus $0.5 million = $231.5 million, with the pledged bills first applied to the facility.
Holder claims: $235.0 million of tokens outstanding. Net coverage = 231.5 / 235.0 = 98.5%, against a gross figure of 250.0 / 235.0 = 106.4%.
Examples from AltStreet's reviews
Superstate USTB: Protocol Redeem's liquidity facility, provided by an affiliate, can charge interest paid by the fund, and its claims rank senior to shareholders if the fund defaults or becomes insolvent.
Figure YLDS: $994,000 of GAAP equity at June 30, 2026 against $556.0 million of certificates; certificates are not secured by any particular asset of the issuer; reliance on a parent support commitment.
Ondo Global Markets notes: backed one for one plus a buffer, with a security agent holding a first-priority security interest for token holders, which improves holders' ranking against other creditors.
How investors apply the term
Investors usually apply this term by tying the definition back to the controlling documents and then asking which cash flows, rights, restrictions, or valuation assumptions it changes. A useful review looks at the term alongside fees, leverage, liquidity, reporting frequency, and manager discretion rather than treating it as a standalone concept.
The practical diligence test is simple: identify who benefits if the assumption is wrong, who has control when conditions change, and what evidence the investor receives after closing. Terms that cannot be reconciled to documents, cash movements, and monitoring data should be treated as marketing shorthand until proven otherwise.
Frequently asked questions
- Why are liabilities necessary to evaluate token backing?
- Because backing is a comparison. $100 million of reserves backs $100 million of tokens only if nothing else is owed ahead of or alongside the holders. A facility with senior claims, unpaid fees or other creditors can leave holders short even when reserves equal tokens outstanding. PCAOB staff warned in March 2023 that proof-of-reserve procedures likely do not address an entity's liabilities.
- What counts as a liability for a tokenized fund or note?
- Tokens or units outstanding on every recognized chain and in book entry; redemptions payable; borrowings and liquidity facility advances; accrued management and other fees; and, for a note or certificate issuer, all of its other creditors. Superstate's USTB, for example, discloses that its liquidity facility provider's claims rank senior to shareholders if the fund defaults or becomes insolvent.
- How can a holder check that their own balance is counted?
- For tokenized securities, compare your on-chain balance and your transfer agent statement, and check that the issuer's published supply across chains and book entry equals the units outstanding in its financial reports. Exchange-style liability proofs let a customer verify inclusion in a published tree of balances without revealing other customers' data.
- What is a coverage ratio, and how should it be read?
- Reserves available to holders divided by holder claims. Compute it after subtracting liabilities that rank ahead of holders and any reserves pledged to others. A ratio above 100% on gross figures can fall below 100% once senior claims and encumbrances are taken out.
