When you buy a tokenized asset, you own three things stacked on top of each other: a token in your wallet, a legal claim that the token represents, and - underneath both - the real asset that actually produces the value. The token is the record of ownership, not the asset itself. What protects you if something goes wrong is the legal claim, and who holds the keys decides how much day-to-day control you have.

Key takeaways

• The token is a record of ownership, not the asset. The value comes from the real asset and the legal claim beneath it.
• Most return-paying RWAs are security tokens: your legal claim is usually shares in the entity that holds the asset.
• "Custody" means two separate things - who holds the asset off-chain, and who holds the keys to your token.
• With a self-custody wallet you control the token yourself; with a custodial account a provider holds it for you. Each carries different risks.
• A token with no enforceable claim behind it is a number on a screen. Check the claim before you check the chart.

What you actually own

Buying a tokenized asset is not like buying a physical thing you take home. You end up holding a token, but the token is only useful because of what sits behind it. Think of three layers: the token on-chain, the legal claim it stands for, and the asset that generates the money.

The layer people see is the token - a balance in a wallet, transferable in minutes. The layer that matters when something breaks is the legal claim. In most deals the asset is parked in a special-purpose vehicle, a company whose only job is to hold that one asset, and your token maps to shares or a membership interest in that company. That claim - not the token's code - is what a court, a liquidator, or a buyer would recognize.

The three layers of ownership

Here is how the layers line up, from the record you hold down to the thing that makes the money:

Read it bottom-up. The underlying asset produces rent, interest, or sale proceeds. The legal claim entitles you to your slice of that through fractional ownership. The token is the on-chain record that says the claim is yours and lets you move it. If any layer is missing or weak - no real asset, no enforceable claim, a token that does not actually map to the shares - the stack does not hold, no matter how clean the smart contract looks.

Who holds the keys: self-custody vs custodial

"Custody" gets used two ways in RWAs, and conflating them causes most of the confusion. The first is custody of the asset: who physically holds the Treasury bills, the gold, or the deed off-chain. For a regulated deal that is usually a qualified custodian, a licensed institution whose job is to safeguard client assets. The second is custody of your token: who holds the keys.

With self-custody, your token lives in a wallet only you control through its private key. You can hold and move the token without asking anyone, but if you lose the key, no one can recover it for you. With custodial access, a platform holds the token on your behalf - easier to recover, but you are trusting that platform and its controls. Either way, security tokens are usually locked to approved addresses: the contract only lets approved wallets hold the token, and a transfer agent keeps the official register of who owns what. So even in self-custody, you cannot freely send a regulated token to just anyone.

What to check before you buy

Judge the ownership before the yield. A few concrete questions cut through most of it:

• What is the legal claim? Shares in an SPV, a note, a fund interest - and is it documented? "You own a token" is not an answer.
• Where is the asset, and who holds it? A named qualified custodian beats a vague "held securely."
• Can you verify the backing? Look for ongoing proof of reserves or audited reporting, not a one-time claim.
• Who holds your keys, and can you exit? Understand self-custody vs custodial, the approved-wallet rules, and how you would ever sell.

If the answers are thin, the token is the easy part and the ownership is the risk.
