Tokenizing a real world asset means issuing a blockchain token that represents legal or economic rights to something that exists off-chain, such as a bond, a building, a barrel of oil, or a private loan. The token itself has no independent value; it is a digital claim whose worth is tied to the underlying asset, verified through legal agreements, custodians, or oracles that feed real-world data such as price or ownership status onto the chain.
The fastest-growing category has been tokenized short-term government debt. Products like BlackRock's BUIDL fund and Franklin Templeton's BENJI let institutions hold U.S. Treasury exposure on-chain with near-instant settlement and 24/7 transferability, something traditional custodial rails cannot offer. Private credit, tokenized real estate, commodities, and carbon credits have followed, with total on-chain RWA value (excluding stablecoins) reaching tens of billions of dollars by 2026, spread across dozens of platforms and multiple blockchains.
RWAs matter for DeFi because they let protocols use assets with independent, less-volatile cash flows as collateral or yield sources, connecting on-chain liquidity to traditional finance. Tokenization can also fractionalize otherwise illiquid holdings like commercial property, letting smaller investors buy a slice rather than the whole asset.
The main risks are not blockchain risks but off-chain ones: whether the issuer actually holds the underlying asset, whether legal claims are enforceable if the issuer fails, and whether a token can be redeemed or resold quickly. Regulatory treatment also varies significantly by jurisdiction and asset type, and many RWA tokens remain restricted to whitelisted, accredited investors rather than freely tradable on open markets.
