Most of what you swap on Base is crypto native. ETH, an ERC-20 token, a stablecoin backed by reserves an issuer holds somewhere. All of it lives entirely onchain, and the token itself is the whole asset. A growing category of tokens works differently. They represent a claim on something that exists off chain, a share of a money market fund, a Treasury bill, sometimes a piece of real estate. This is usually called a tokenized real world asset, or RWA for short. It is worth understanding, because it looks like an ordinary token in your wallet but behaves nothing like one under the surface.
What tokenization actually means
A tokenized real world asset is a digital record of ownership, or of a claim, over something that a custodian or issuer holds in the traditional financial system. The asset itself, a bond, a fund share, a piece of property, does not move onto the blockchain. What moves onchain is a token that the issuer has agreed represents your interest in that asset, along with a promise to honor redemptions according to whatever legal structure sits behind the token.
That is a meaningfully different relationship than holding ETH or a typical ERC-20. When you hold ETH, there is no issuer to ask permission from and no off chain paperwork backing it. The blockchain is the entire system of record. With a tokenized RWA, the blockchain is one part of the system of record, but a company, a fund administrator, or a transfer agent still sits behind it, and their books ultimately decide who owns what.
What this looks like on Base today
The clearest working example is Franklin Templeton's BENJI, the onchain share token for its US Government Money Fund, which invests in Treasury bills and government agency securities. BENJI is not exclusive to Base. It runs across nine public blockchains, Base among them, and the fund itself was one of the first US registered mutual funds to use a public blockchain as part of its official system of record.
Base has also been building infrastructure with this category in mind. Its B20 token standard, introduced in 2026, was designed specifically for regulated stablecoins and tokenized assets, with compliance features like allowlists and issuer level freeze controls built directly into the token type rather than added on as an afterthought. That is a strong signal of where Base expects more of this activity to land over time, even though most tokens you will encounter day to day remain ordinary, permissionless ERC-20s.
Why you usually cannot just swap into one
This is the part that catches people off guard. Most tokens on Base can be bought by anyone with a wallet and some ETH for gas, no identity check required. Tokenized RWAs typically do not work that way. BENJI, for example, uses an allowlist. Only wallet addresses that have completed the issuer's identity verification can hold or receive it, and a transfer to an address that has not been cleared is blocked at the contract level, regardless of whether the sender approves it.
That does not always mean these products are limited to large institutions. BENJI does not require accredited investor status for US retail participants, since the underlying fund is a registered investment company rather than a private placement, and it is accessible through Franklin Templeton's own onboarding app rather than a decentralized exchange. The gatekeeping happens at the issuer's front door, not in a liquidity pool, the opposite order of operations from acquiring tokens through a swap.
A different kind of risk than a rug pull
Most risk explainers on this site focus on onchain risk: a malicious contract, a drained liquidity pool, a fake token. For good reason, that is where most self custody losses happen. Tokenized RWAs mostly sidestep that category, since spotting a scam token is not really the concern with a fund run by a regulated asset manager. What they introduce instead is closer to traditional counterparty risk. Your claim is only as good as the issuer's solvency, their legal structure, and their willingness to honor redemptions. A smart contract audit does not protect you from a fund administrator freezing operations, and no amount of onchain transparency changes the fact that a court, not a blockchain, is the final backstop if a dispute arises.
Getting your money back does not look like a swap
With a normal token, you exit by selling it into a liquidity pool. With most tokenized RWAs, there usually is no deep pool to sell into, since the tokens are restricted to allowlisted holders and are not built for open market trading the way a typical ERC-20 is. Redemption instead happens through the issuer's own process, converting the token back to cash through the same app or institutional channel you used to acquire it. If you ever hold one, it is worth knowing in advance whether an active secondary market even exists, rather than assuming you can exit the way you would exit an ordinary swap.
Why this is worth knowing even if you never hold one
You are unlikely to stumble into a tokenized RWA by accident. They will not show up as a surprise swap route the way a scam token might, precisely because the allowlist keeps them out of open trading. But as more regulated products move onchain, wallets and block explorers will keep surfacing them next to ordinary tokens, and it helps to recognize the difference on sight.
The short version
A tokenized real world asset represents a claim on something held off chain by a regulated issuer, not a self contained crypto asset. These tokens usually require identity verification to hold, cannot be freely traded on the open market the way ordinary tokens can, and carry issuer and legal risk rather than smart contract risk. Base already hosts a working example in Franklin Templeton's BENJI, and its B20 standard suggests more are coming. None of this changes how you use Simple Base Swap day to day, but it is a useful category to be able to name when you see it.
