Underlying Asset

The underlying asset is the real thing a token stands for: the building, the Treasury bill, the loan, the gold bar. A real-world asset token has value only because it carries a claim on this off-chain asset and the cash it produces. Take the underlying asset away and the token is worthless.

This is the single most important thing to check about any RWA. The token lives on-chain, but the asset lives in the real world, and the two are linked only by a legal structure - usually a company that holds the asset and agreements that assign its economics to token holders. If that link is weak, the token and the asset can come apart.

Three questions tell you whether an underlying asset is real and properly connected:

• Does it exist and is it owned? Title, custody records, or an audit should confirm the asset is there and held by the issuing entity.
• Who holds it? A qualified custodian or a clearly identified owner, not just the sponsor's word.
• Is it verified over time? Ongoing proof of reserves or third-party attestation keeps the on-chain supply honest against the real holdings.

A concrete case: Paxos Gold tokens are each backed by a specific allocation of a 400-oz London gold bar held in vaults, with monthly attestations. The bar is the underlying asset; the token is just a claim on it.

When an underlying asset is vague, unaudited, or held by an unnamed party, treat the token as unbacked until proven otherwise.
