What is RWA tokenization?
RWA tokenization creates a blockchain token that represents ownership of a real-world asset. The asset sits in a custody structure off-chain. The token trades on-chain. A redemption mechanism connects the two: burn the token, receive the underlying asset (or its cash equivalent). This is the entire concept. Everything else is implementation detail.
The assets being tokenized fall into a few categories: government debt (US Treasury bills, European sovereign bonds), private credit (trade finance, revenue-based loans, real estate debt), commodities (gold, silver), and equity or fund shares. Each has different custody requirements, regulatory treatment, and redemption mechanics.
BlackRock launched BUIDL (the BlackRock USD Institutional Digital Liquidity Fund) on Ethereum via Securitize in March 2024. It reached $500 million in AUM within months. Franklin Templeton runs an on-chain money market fund on Stellar and Polygon. Apollo acquired up to 9% of Morpho's token supply, partly to access on-chain distribution for tokenized credit products. These are not experiments. Institutional capital is entering.
How tokenization works
The SPV structure
Most tokenized securities use a special purpose vehicle (SPV). The SPV is a legal entity that holds the underlying assets. It issues tokens on a blockchain, each representing a proportional claim on the SPV's holdings. The SPV is bankruptcy-remote from the issuer: if the issuer goes bankrupt, the SPV's assets are ring-fenced. This is standard securitization practice, adapted for blockchain rails.
Ondo Finance's OUSG works this way. An SPV holds short-dated US Treasuries. OUSG tokens represent shares in the SPV. The token price tracks the NAV of the underlying portfolio. Minting requires KYC and minimum investment (typically $100,000). Redemption burns the token and triggers a wire transfer within T+1 to T+3.
Transfer agents and compliance
Securitize acts as the transfer agent for several tokenized products, including BlackRock's BUIDL. The transfer agent maintains the official record of token holders and enforces transfer restrictions. On-chain, this is implemented through whitelists: only addresses that have completed KYC can hold the token. Attempted transfers to non-whitelisted addresses revert.
This creates a tension with DeFi composability. A permissioned token cannot be freely deposited into a permissionless lending pool. Some protocols solve this with wrapper contracts that handle compliance at the pool level. Others accept that certain RWA tokens will remain in permissioned DeFi environments.
Smart contract layer
The token contract is usually an ERC-20 with additional features: transfer restrictions (whitelist enforcement), pausability (regulatory compliance), and often upgradeability via proxy patterns. Some issuers use ERC-1400 (security token standard) which adds partition-based transfers and document management. The contract complexity is low compared to DeFi protocols. The risk sits in the off-chain custody and legal structure, not the smart contract.
Asset classes
Tokenized treasuries
The largest RWA category by TVL. Protocols like Ondo (OUSG, USDY), Backed Finance (bIB01), Matrixdock (STBT), and Mountain Protocol (USDM) tokenize US Treasury bills or money market fund shares. Yields track the fed funds rate minus issuer fees, typically 4 to 5% at current rates. These products compete with stablecoin yields: when DeFi lending rates fall below Treasury rates, capital flows from on-chain lending into tokenized treasuries.
USDY (Ondo) is a rebasing token. The balance in your wallet increases daily as yield accrues. OUSG is non-rebasing: the token price increases instead. bIB01 (Backed) tracks a specific iShares ETF. The design choice affects composability: non-rebasing tokens work better as collateral in lending protocols because the share accounting is simpler.
Private credit
Centrifuge, Goldfinch, Maple Finance, and Clearpool connect on-chain lenders with off-chain borrowers. The borrower is a real-world entity: a fintech company, a trade finance operator, a real estate developer. Loans are structured as pools. On-chain depositors supply capital. The borrower draws from the pool and repays with interest.
Default risk is the primary concern. Maple suffered $54 million in defaults during the 2022 credit cycle when FTX/Alameda-linked borrowers failed to repay. Goldfinch lost capital on several emerging market loans. Unlike DeFi lending where collateral is on-chain and liquidatable in seconds, off-chain default recovery involves legal proceedings across jurisdictions. Compare RWA protocols.
Commodities
Paxos Gold (PAXG) and Tether Gold (XAUT) are the two largest tokenized gold products. Each token represents one troy ounce of gold held in London vaults. PAXG is regulated by NYDFS. Redemption means physical gold delivery or cash settlement. The on-chain token trades 24/7, unlike the LBMA gold market which has limited trading hours. Gold-backed tokens serve as an inflation hedge and portfolio diversifier within DeFi treasuries.
Real estate and securities
Tokenized real estate is fragmented. RealT offers fractional ownership of rental properties in Detroit and other US cities. Lofty tokenizes properties on Algorand. The challenge is liquidity: real estate tokens trade thinly. Securities tokenization (stocks, bonds, fund shares) faces regulatory barriers in most jurisdictions but is advancing in Switzerland, Singapore, and the UAE.
RWA in DeFi
MakerDAO (now Sky) was the first major DeFi protocol to integrate RWAs. Its PSM (Peg Stability Module) and vault system allocated billions of DAI backing into tokenized treasuries and real-world credit lines. At peak, over 60% of DAI's collateral consisted of real-world assets. This generated stable revenue for the protocol independent of on-chain lending demand.
Aave has approved proposals to accept certain tokenized treasuries as collateral. Morpho markets exist for RWA tokens. Centrifuge's integration with MakerDAO created a template: the Centrifuge pool handles compliance and borrower underwriting, while MakerDAO provides the liquidity. This separation of concerns lets DeFi protocols access real-world yields without handling regulatory compliance directly.
The constraint is composability. A permissioned token (requiring KYC for transfers) cannot freely interact with permissionless protocols. Solutions include wrapper contracts, dedicated compliant pools, and "DeFi-native" RWA designs like USDY that handle compliance at the token level rather than the protocol level. Explore RWA protocols.
Regulatory landscape
The regulatory treatment of tokenized securities depends on the jurisdiction and the asset type. In the US, most tokenized securities are offered under Reg D (accredited investors, restricted transfers, no SEC registration required) or Reg S (non-US persons only). Reg A+ allows general public offerings with a $75 million annual cap but requires SEC qualification.
The EU's MiCA regulation, effective mid-2024, covers crypto-assets but explicitly excludes financial instruments that qualify as securities under MiFID II. Tokenized bonds and fund shares fall under MiFID II, not MiCA. This means tokenized securities in the EU must comply with existing securities regulation, including prospectus requirements, CSDR settlement rules, and MiFID II distribution rules.
Switzerland has been ahead of most jurisdictions. Its DLT Act (2021) created a legal framework for ledger-based securities (Registerwertrechte). SIX Digital Exchange operates a regulated exchange for tokenized securities. Singapore's MAS allows tokenized securities under existing capital markets regulation and has granted multiple licenses to tokenization platforms.
The practical impact: issuers choose their jurisdiction and regulatory framework based on target investors. US issuers tend to use Reg D for institutional products. European issuers use national securities regulation. Offshore issuers (Cayman, BVI) use structures that avoid US and EU jurisdiction entirely. The token lives on Ethereum regardless of where the legal structure sits.
Risks
Counterparty and custodial risk
The token is a claim on an off-chain asset held by a custodian. If the custodian fails, the underlying asset may be frozen or lost. If the issuer becomes insolvent, the SPV structure should protect assets, but legal proceedings take time and outcomes are uncertain. The bankruptcy-remote nature of SPVs has been tested in traditional finance but not yet stress-tested at scale for tokenized assets.
Credit and default risk
For private credit protocols, the borrower may default. Centrifuge pools have experienced defaults. Goldfinch lost capital on emerging market loans. Unlike on-chain overcollateralized lending where liquidation is programmable, off-chain recovery involves collection agents, courts, and potentially years of litigation. Loss-given-default rates in tokenized private credit are not well established because the market is young.
Regulatory risk
A regulatory change could restrict transfers, force delisting from exchanges, or require costly compliance upgrades. The SEC has taken enforcement action against token issuers who failed to register securities. Jurisdictional arbitrage (issuing from Cayman while selling to US residents) is under increasing scrutiny. Any tokenized security product should be evaluated for regulatory sustainability, not just current compliance.
Liquidity and redemption risk
Many RWA tokens trade thinly on secondary markets. Redemption with the issuer may take T+1 to T+5, compared to instant settlement in DeFi. During a market stress event, redemption queues could form. Gate mechanisms (limits on daily redemptions) are common in fund structures and apply to many tokenized products. The on-chain token may trade at a discount to NAV if redemption is slow or uncertain.

Frequently asked questions
RWA tokenization is the process of creating a blockchain token that represents ownership of, or economic exposure to, a real-world asset. The asset could be a US Treasury bill, a commercial real estate loan, a gold bar, or a corporate bond. The token is issued on a blockchain (usually Ethereum, sometimes Stellar or Solana) and can be transferred, traded, or used as collateral in DeFi protocols. The underlying asset is held by a custodian or trust structure, and the token's value tracks the asset's value through redemption mechanisms or market pricing.
An issuer (e.g., Ondo Finance, Backed Finance, Matrixdock) purchases US Treasury bills or money market fund shares through a traditional broker-dealer. A special purpose vehicle (SPV) holds the securities. The SPV issues tokens on-chain, each representing a fractional interest in the portfolio. The token accrues yield from the underlying T-bills. Token holders can redeem by burning their tokens, which triggers the SPV to sell the underlying securities and send USD to the holder's bank account. Most tokenized treasury products require KYC for minting and redeeming, though secondary market trading may be permissionless depending on the jurisdiction and token design.
In DeFiLlama's taxonomy, 'RWA' protocols are asset issuers that create tokenized versions of real-world assets (treasuries, gold, real estate). 'RWA Lending' protocols are lending platforms that accept tokenized RWAs as collateral or lend against real-world credit obligations. Centrifuge and Goldfinch are RWA Lending: they connect on-chain lenders with off-chain borrowers. Ondo and Backed are RWA: they tokenize the assets themselves. Some protocols span both categories.
Counterparty risk is the primary concern: the token's value depends on the issuer honoring redemptions and the custodian safeguarding the underlying asset. Smart contract risk exists at the token layer. Regulatory risk is significant: jurisdictions treat tokenized securities differently, and a regulatory change could restrict transfers or force delisting. Liquidity risk applies to less-traded tokens. For credit-backed RWAs (private credit, real estate loans), the borrower may default. Unlike DeFi lending where collateral is on-chain and liquidatable, off-chain default recovery involves legal proceedings that take months or years.
Some can. Tokenized treasuries like Ondo's USDY and Backed's bIB01 are used as collateral in DeFi lending protocols. MakerDAO (now Sky) allocated billions of its reserves to tokenized treasuries. Morpho and Aave have markets that accept certain RWA tokens. The limitation is transfer restrictions: most tokenized securities require KYC, which conflicts with permissionless DeFi. Protocols like Centrifuge's Tinlake and Maple Finance created dedicated pool structures that handle compliance at the protocol level, allowing permissionless lending pools with KYC'd borrowers.
As of early 2026, tokenized treasury products hold over $3 billion in TVL across protocols tracked by DeFiLlama. Private credit protocols (Centrifuge, Goldfinch, Maple, Clearpool) hold roughly $500 million to $1 billion in active loans. Tokenized gold (Paxos Gold, Tether Gold) represents another $1 billion+. The total on-chain RWA market is roughly $5 to $8 billion depending on what you count. For context, BlackRock's BUIDL fund (tokenized on Ethereum via Securitize) reached $500 million within months of launch. The market is growing fast but remains a fraction of the $200+ trillion traditional fixed income market.
Ethereum dominates by TVL, hosting most tokenized treasury products and private credit protocols. Stellar is used by Franklin Templeton's on-chain fund. Solana hosts some tokenized treasury products. Polygon, Arbitrum, and Base have growing RWA activity. The choice of chain often depends on regulatory infrastructure: some issuers prefer Ethereum for its institutional tooling (multisig wallets, compliance middleware, established custodian integrations). Newer issuers are deploying on L2s for lower transaction costs.
It varies by jurisdiction. In the US, most tokenized securities fall under SEC jurisdiction and must comply with Reg D (accredited investors only), Reg S (non-US only), or Reg A+ (general public with limits). The EU's MiCA regulation provides a framework for crypto-assets but tokenized securities may fall under MiFID II instead. Singapore's MAS has been relatively permissive. Switzerland allows tokenized securities under existing DLT legislation. The key issue is whether a specific token is classified as a security, a fund share, or a payment instrument, as each classification triggers different compliance requirements.
