Real World Assets
The yield gap
By 2023, DeFi had a structural problem. The yield opportunities that defined 2020–2021 had compressed: Aave lending rates settled to 2–4% on stablecoins, Uniswap LP yields normalized to 3–6% on major pairs, and protocol-token rewards had diluted to near-zero real yields. Meanwhile, the US Federal Reserve had raised rates to 5.25%, meaning a money market fund earned more than most DeFi strategies — without smart contract risk, without liquidation risk, without any of the complexity.
Real-world assets solve this by importing yield from outside DeFi. RWAs tokenize T-bills, money market fund shares, private credit, and other yield-bearing instruments and bring them onto blockchains where they can earn 4–6% while remaining composable with DeFi protocols — usable as collateral, held in vaults, integrated into lending markets.
The institutional signal
The most important signal in RWAs is who showed up to build them. BlackRock launched BUIDL — a tokenized money market fund — in March 2024 with Franklin Templeton, JPMorgan, and State Street as early participants. These are not firms that build experiments. They build products with compliance infrastructure, institutional-grade custody, and long-term capital commitments behind them. When the world's largest asset manager builds a tokenized fund, it is saying that blockchain distribution rails are real and persistent enough to justify the build cost.
Tokenized RWAs grew from near-zero in 2021 to over $300 billion by mid-2025, led by tokenized T-bills and money market funds. Private credit added roughly $12 billion, real estate and commodities the remainder. The category is growing faster than any other segment of on-chain finance — because the underlying demand driver (yield) is structural, not speculative.
The tokenization stack
A tokenized T-bill is not a T-bill on a blockchain. It is a blockchain token that represents a legal claim on an off-chain entity that holds T-bills. Understanding the distinction matters because the full stack between the on-chain token and the underlying asset is where the risk lives.
Layer 1 — Legal wrapper
A SPV or fund structure holds the underlying asset. This is the legal entity that actually owns the T-bills. Investors in the token have a legal claim on the SPV — not on the T-bills directly. The SPV structure isolates the assets from the issuer's bankruptcy risk (in theory), but introduces SPV-specific risks: governance, fees, jurisdiction.
Layer 2 — Compliance
Tokenized securities are securities. KYC/AML checks and investor eligibility (accredited investor status in the US, equivalent in other jurisdictions) are enforced at the transfer layer, not just at purchase. Most tokenized RWA products use allowlists: only wallets that have completed the compliance process can hold or receive the token. This makes RWA tokens incompatible with anonymous DeFi participation — which is why the products that reach DeFi typically go through a wrapper layer (Ondo's USDY wrapping BUIDL is the canonical example).
Layer 3 — Issuance and distribution
The smart contract mints tokens proportional to deposits into the SPV. Distribution to DeFi requires a secondary step: either the token itself is DeFi-compatible (rare, due to compliance restrictions) or a wrapper product converts the institution-only token into a format that permissionless DeFi can use. Ondo Finance's model — hold BUIDL shares, issue USDY as a transferable rebasing token — is the pattern most of the industry has converged on.
Layer 4 — Redemption
This is the seam where on-chain speed and off-chain settlement collide. Burning tokens initiates an off-chain process:
- T+0 — BUIDL offers same-day redemption via USDC liquidity facility
- T+1 — standard US T-bill settlement after redemption request
- T+3 to T+5 — private credit, real estate, less liquid assets
During stress events, redemption queues form. The secondary market on a DEX may offer faster exit — at a discount. The spread between the token's face value and its secondary market price during stress is the redemption risk premium made visible.
What gets tokenized
Not all RWA categories are equally mature. Tokenized T-bills are production infrastructure. Private credit is live but requires careful underwriting. Real estate and commodities remain early-stage with limited on-chain liquidity.
Tokenized T-bills and money market funds
The dominant RWA category by TVL. Short-duration US government debt carries near-zero credit risk and yields 4–5% at typical policy rates. The tokenization value proposition is straightforward: hold T-bill yield while keeping capital accessible on-chain for DeFi collateral, vault deposits, or DAO treasury management.
Key products: BlackRock BUIDL, Franklin Templeton BENJI, Ondo OUSG/USDY, Hashnote USYC. The differentiation is access tier (minimum investment, KYC requirements), redemption speed, and chain availability (Ethereum-only vs multi-chain).
Private credit
Loans to real companies — borrowers who have completed KYC and typically operate in regulated industries (fintech, trading firms, emerging-market lenders). Yields range from 8–15% depending on borrower quality and loan structure. The yield premium over T-bills compensates for credit risk: defaults happen, and the recovery process takes months or years.
Maple Finance focuses on institutional borrowers (crypto trading firms, fintech companies). Centrifuge connects real-world SMEs — invoice financing, trade finance, royalty streams — to on-chain capital. Both platforms use senior/junior tranche structures where the junior tranche absorbs first losses, offering different risk/return profiles.
Real estate
The promise: fractionalized ownership of buildings with on-chain liquidity. The reality: real estate is illiquid by nature, and the legal frictionof property transfer doesn't disappear because the token is on-chain. Regulatory complexity varies by jurisdiction — property ownership law differs dramatically across countries, making cross-border products hard. Early-stage; few production products with meaningful TVL.
Commodities
Paxos Gold (PAXG) and Tether Gold (XAUT) represent physical gold held in custody, tradeable on-chain. Gold-backed tokens give DeFi users commodity exposure and a collateral option with low correlation to crypto. The category hasn't grown beyond gold — other commodities (oil, copper, agricultural) face custody complexity that gold's fungibility and density make easier to solve.
Reading the protocols
The key protocols in the RWA space differ in who they're for, how they manage compliance, and how they bridge into DeFi. Understanding those differences is what separates informed allocation from brand recognition.
BUIDL — BlackRock / Securitize
The institutional benchmark. BUIDL is a SEC-registered fund investing in cash, US Treasury bills, and repurchase agreements — the same instruments a money market fund holds. Securitize acts as transfer agent, managing the allowlist of permissioned wallets. Minimum investment is $5M, making it institutional-only by construction. Dividends accrue daily and distribute as USDC monthly.
What makes BUIDL foundational: it's whitelisted for on-chain smart contracts, meaning other protocols can hold BUIDL in their smart contracts (within compliance rules). Ondo Finance holds BUIDL as the primary collateral backing USDY — so a retail user in USDY is indirectly holding BUIDL exposure.
USDY and OUSG — Ondo Finance
Ondo's two-tier model bridges institutional RWAs to retail-accessible on-chain yield. OUSG is the institutional product: direct T-bill exposure (primarily via BUIDL), $5K minimum, KYC required, available on Ethereum and Solana. USDY is the retail product: $500 minimum, broader distribution, represents senior-secured notes backed by US Treasuries and bank demand deposits.
USDY is a rebasing token — the number of USDY in your wallet increases to reflect accrued yield, rather than the price per token increasing. This makes USDY behave more like a stablecoin than an investment, which improves DeFi composability. Aave V3 on Ethereum has approved OUSG as a collateral asset.
BENJI — Franklin Templeton
Franklin Templeton's blockchain-native mutual fund — the first US-registered mutual fund to use a public blockchain as its authoritative record. The fund (FOBXX) holds short-term US government securities. BENJI tokens on Stellar and Polygon represent fund shares; the blockchain ledger is the official record, not a secondary copy.
BENJI is significant as a regulatory proof of concept: a legacy asset manager got a traditional mutual fund wrapper to work on a public blockchain, without creating a new legal structure. The approach — blockchain as ledger rather than blockchain as asset — is likely the template for large fund managers who need to move within existing regulatory frameworks.
Maple Finance
Institutional undercollateralized lending. Borrowers are vetted, KYC'd financial institutions: crypto trading firms, fintech lenders, digital asset companies. Lenders deposit into pools managed by professional pool delegates who assess borrower creditworthiness and set rates. Yields range from 8–12% on active pools.
Maple's risk profile is fundamentally different from T-bill products. When a borrower defaults — as several did during the 2022 crypto credit crisis — lenders face extended recovery processes. Maple V2 introduced first-loss capital requirements for pool delegates, aligning their incentives with lender outcomes. Cash Management Pools offer T-bill exposure for conservative allocators who want Maple's infrastructure without credit risk.
Centrifuge
Centrifuge connects real-world asset originators — invoice financing companies, trade finance firms, real estate lenders — to on-chain capital markets. Originators pool real-world loans into structured vehicles with two tranches: DROP (senior, lower risk, lower yield) and TIN (junior, first-loss, higher yield). DeFi protocols invest in DROP through Centrifuge's integration with Aave and MakerDAO.
MakerDAO's RWA program — which helped grow DAI from $5B to $10B in circulating supply — was largely built on Centrifuge pools. The protocol's strength is in geographic diversity: originators span Southeast Asia, Africa, and Latin America, accessing capital markets that don't serve them through traditional channels.
The risk framework
RWA investment requires evaluating off-chain risk that DeFi-native analysis doesn't cover. The five-category framework below maps the failure modes, from most common to most structural.
Custody risk
Every tokenized RWA has an off-chain custodian holding the underlying asset. That custodian is a counterparty. Bank failure, custodian insolvency, or operational failure breaks the redemption chain regardless of the on-chain token's behavior.
The March 2023 USDC depeg is the canonical example: Circle had $3.3B of USDC reserves deposited at Silicon Valley Bank when it failed over a weekend. USDC dropped to $0.87 before the Fed backstop was announced Monday morning. The on-chain token was flawless; the off-chain custodian was the point of failure.
Evaluation checklist: Who holds the underlying? What is their regulatory status (FDIC coverage applies up to $250K; most institutional deposits are uninsured above that)? Is there geographic or counterparty concentration?
Redemption risk
On-chain liquidation triggers are instant. Off-chain settlement takes T+1 to T+5 or more. When DeFi collateral is liquidated, the liquidator expects to receive value immediately — but the RWA token's face value is only accessible after the redemption process completes. Secondary market pricing bridges this gap: the token trades at a small discount to NAV to reflect the settlement wait.
During stress events, that discount widens. If multiple large holders try to exit simultaneously, secondary liquidity dries up and the discount can become significant. Protocols that use RWA tokens as collateral should model redemption stress scenarios, not just normal-market liquidity.
Regulatory risk
Tokenized securities are securities. The SEC has explicit jurisdiction and has made it clear that registering a token on a blockchain does not exempt it from securities law. Products available to US retail investors are a small minority; most institutional RWA products are Regulation D (accredited investors only) or offshore (Regulation S).
Regulatory status is not static. Crypto-friendly policies under the current administration created more room for tokenized securities in 2025, but that posture can change. The jurisdictional arbitrage that made some products work (Cayman SPV, Bermuda incorporation, Stellar distribution) could close. Evaluate what jurisdiction a product depends on and whether the legal structure survives a regulatory shift.
Oracle risk
DeFi protocols price RWA collateral using on-chain oracles. The oracle determines when collateral is undercollateralized and triggers liquidation. If the oracle is stale (T-bill hasn't had a price update — weekends, holidays, system outages) or manipulable, the protocol's liquidation logic can fire incorrectly or fail to fire when needed.
Unlike crypto-native assets with continuous market prices, T-bill NAV updates daily (or more frequently for some products). Protocols built on RWA collateral need oracle infrastructure designed for this update cadence, not the continuous-update oracle design used for ETH/BTC.
Smart contract risk
The on-chain wrapper is a smart contract. Bugs in the token contract — the allowlist logic, the rebasing mechanism, the dividend distribution — are independent of the quality of the underlying asset. A perfect T-bill with a buggy token contract is still a risk.
RWA products from established institutions (BlackRock, Franklin Templeton) receive significant audit and operational scrutiny, but institutional brand does not guarantee smart contract correctness. Evaluate audit history, contract upgradeability (can the issuer change the rules?), and emergency pause mechanisms as you would for any DeFi protocol.
