Tokenized assets can move on-chain, but most of the facts that give them value still live elsewhere.

A blockchain cannot independently confirm whether a custodian still holds a security, a property has been sold, a borrower defaulted, a reserve became encumbered or a fund administrator revised its net asset value. Smart contracts need external systems to bring those facts on-chain.

That is why RWA oracle risk is broader than price manipulation.

An oracle may publish a value correctly while the source itself is stale, incomplete or based on the wrong economic definition. A market-price feed is not the same as fund NAV. A reserve balance is not proof of solvency. Evidence that an asset exists is not proof that token holders have an enforceable claim on it.

Timing makes the problem harder. Blockchains operate continuously, while securities markets, administrators, banks and custodians follow business hours and reporting schedules. A Friday value may still be visible on Sunday even though the surrounding risk has changed. If an automated lending market treats that value as current, it can overvalue collateral, trigger incorrect liquidations or allow credit against weak backing.

Strong RWA systems need more than a recognizable oracle provider. They need explicit staleness limits, clear timestamps, market-hours logic, conservative collateral haircuts, compatible backup sources and emergency procedures. Governance also matters. Users should know who can change the source, increase collateral factors, pause liquidations or restore a disputed feed.

Small implementation errors can be dangerous too. A decimal mismatch, wrong currency, delayed NAV update or confused asset identifier can produce an incorrect on-chain value without any sophisticated attack.

As tokenized securities enter real production workflows, the quality of the truth layer becomes part of market security. Reliable automation begins with understanding exactly what each feed measures, who produced the underlying fact and how the protocol responds when that fact is late or contested.
