"Backed by real assets" is the most common phrase in tokenized asset marketing. It is also the least specific. An ounce of gold, a US Treasury bill, a loan to a Brazilian sugarcane company, and a fractional interest in a Phoenix office building can all be described as "real assets." Verifying that the backing is real — and that the backing matches what the marketing says — requires going to specific data sources, not taking the issuer's word for it.
This article walks through the verification process for the most common forms of backing claim, in order from easiest to verify to hardest.
Attestations vs. Audits: The Fundamental Distinction
Before running any verification, understand the difference between an attestation and an audit. They are not interchangeable, and the distinction matters more than most investors realize.
An audit is performed by a registered independent audit firm. It involves the auditor independently verifying the existence and value of the assets — examining source documents, confirming balances with custodians, testing internal controls. The auditor takes professional and legal responsibility for the opinion. A clean audit opinion from a reputable firm (BDO, Grant Thornton, PwC, Deloitte, KPMG, EY) is the gold standard.
An attestation is a narrower engagement. An accounting firm agrees to confirm specific representations by management — typically that the reserve balance on a specific date equals or exceeds the outstanding token supply. The firm is not independently verifying the assets; it is confirming that the issuer's own numbers match the stated claim at a point in time. Attestations are faster and cheaper than audits, and they are what most stablecoin and tokenized asset issuers publish.
A monthly attestation from an accounting firm saying "as of October 1, the reserve balance equals the outstanding token supply" is meaningful. It is not an audit. It does not verify what the reserve consists of, whether the assets are liquid, or whether the custody arrangement is sound. An issuer that publishes monthly attestations is doing more than many — but investors should understand what they are and are not getting.
Verifying Tokenized Treasuries: Start On-Chain
For tokenized US Treasury products — BUIDL, BENJI, USYC, OUSG, and similar — the on-chain verification starts with the block explorer.
Go to Etherscan (etherscan.io) or the relevant chain's explorer and look up the token contract address. The "Token Tracker" shows total supply. The issuer's disclosed AUM should match the token supply times the per-token NAV. If BUIDL has 2.5 billion tokens outstanding at $1 per token, the AUM should be approximately $2.5 billion. If it does not match, ask why.
Check the Mint and Burn events under the "Events" tab. A fund claiming daily redemptions should show daily Burn events — tokens being destroyed as investors redeem. A fund showing no Burn events for 30 days is not processing redemptions at the frequency claimed, or all redemptions are happening through an intermediary that holds the tokens in aggregate.
Cross-reference the on-chain supply with the issuer's published attestation. Ondo Finance publishes monthly attestations for OUSG. Franklin Templeton publishes attestations for BENJI. BlackRock / Securitize publishes attestations for BUIDL. These documents are available on the issuers' websites. If the attestation date is more than 30 days old, it is stale.
Verifying Private Credit Backing
Private credit is harder to verify because the underlying loans are not public instruments. There is no CUSIP to look up, no SEC filing to read. What you can verify:
Does the issuer publish borrower-level data? The most transparent private credit tokenization platforms (Goldfinch, Centrifuge, Maple) publish portfolio-level data showing individual loan terms, borrower names or identifiers, repayment history, and current delinquency rates. This data is publicly accessible. If a private credit product does not publish borrower-level data, you are relying entirely on the issuer's representations about loan quality.
Is there an independent verification of the loan pool? Some structures use a trustee — a regulated financial institution that independently holds the loan documents and verifies that the loans exist and are performing. The trustee publishes periodic reports. If there is no trustee and no independent verification of the loan pool, the backing claim cannot be verified externally.
Check delinquency rates over time, not just at inception. A private credit pool that was 0% delinquent at launch may be 15% delinquent 18 months later. Some tokenized private credit platforms have experienced significant default rates that were not prominently disclosed in ongoing reporting.
Verifying Real Estate Backing
For tokenized real estate, verification starts with the property record. In the United States, property title is a matter of public record at the county recorder's office. If a tokenized real estate product claims to be backed by a specific property at a specific address, you can verify that the listed owner is the SPV described in the offering documents — not the issuing company, not the platform's operating entity.
This is a one-step verification that most investors never run. The county recorder's online search tool (available for most US counties) shows the current legal owner of any property. If the offering says the property is held in "123 Main Street SPV LLC" and the county records show the property is owned by "Real Estate Platform Inc." — the operating company, not the SPV — the legal structure does not match the marketing.
Proof of Reserve: The On-Chain Version
Some asset-backed token issuers implement Proof of Reserve systems — smart contract integrations that pull reserve data from custodians and verify on-chain that the token supply is backed. Chainlink's Proof of Reserve product is one implementation. These systems provide more frequent, automated verification than periodic attestations.
A Proof of Reserve integration does not guarantee that the underlying asset is safe or performing — it only confirms that the reported reserve balance matches or exceeds the token supply at the time of the data feed update. If the reserve consists of low-quality or illiquid assets that have been marked at unrealistic prices, a Proof of Reserve check would not catch that.
Proof of Reserve is better than nothing. It is not a substitute for the full verification process described above.
