Which Tokenized Treasury is Right for You?
US Treasury bills have become the dominant RWA category on-chain — not because they’re the most interesting asset to tokenize, but because they solve a specific problem elegantly: what do you do with idle stablecoin capital that needs to earn yield without leaving the on-chain ecosystem?
Before tokenized treasuries, on-chain capital sat in stablecoins earning nothing, or was deployed into high-risk DeFi yields. Tokenized T-bills changed the calculus: institutional-quality yield (currently ~4.5–5% on short-duration US Treasuries), on-chain composability, and near-instant settlement — all backed by the US government.
The market has grown from essentially zero in 2022 to over $12B on-chain by early 2026. Three products dominate: BlackRock BUIDL (institutional, high minimum, maximum credibility), Ondo Finance OUSG (accredited but lower minimums, DeFi-native), and Superstate USTB (crypto-native team, direct T-bill exposure, SEC-registered fund).
All three products are accredited investor only in the US under Reg D. None are accessible to retail US investors. Non-US investors may have different access depending on their local jurisdiction. Always verify your eligibility before attempting to subscribe to any of these products.
| Feature | BlackRock BUIDL | Ondo OUSG | Superstate USTB |
|---|---|---|---|
| Minimum investment | $5,000,000 | $500 (DeFi) / $100k (direct) | $1,000 |
| Investor type | Institutional only | Accredited + DeFi protocols | Accredited + crypto-native |
| Underlying | T-bills + repo | BUIDL (majority) + T-bills | Direct T-bills only |
| Regulatory status | Reg D, SEC exemption | Reg D, SEC exemption | SEC-registered fund |
| Chains supported | Ethereum (primary) | Ethereum, Polygon, Solana | Ethereum |
| Yield (approx. Q1 2026) | ~4.8% APY | ~4.6% APY (after fees) | ~4.7% APY |
| Redemption speed | T+0 (USDC facility) | T+0 (instant) | T+1 |
| DeFi collateral | Yes — widely used | Yes — Flux, Compound | Limited — growing |
| Custodian | BNY Mellon (AAA) | Ondo-managed (BUIDL-backed) | Direct T-bill custody |
| Transfer agent | Securitize | Ondo (self-managed) | Superstate (self-managed) |
| Brand credibility | Maximum (BlackRock) | Good (DeFi-native) | Strong (a16z-backed) |
| Non-US access | Very limited | Select jurisdictions | Select jurisdictions |
The three products look similar on the surface — all on-chain, all T-bill exposure, all yielding ~4.5–5%. But the underlying architecture, regulatory structure, and counterparty stack are meaningfully different.
Unlike BUIDL and OUSG, Superstate holds T-bills directly — no fund wrapper, no intermediate counterparty. USTB is an SEC-registered investment fund (not Reg D exempt), which gives it a cleaner regulatory status but also means the regulatory overhead is higher. The team are crypto-natives from Compound Finance, backed by a16z. USTB is the product for investors who want direct T-bill exposure with maximum regulatory clarity and a crypto-native interface — but are comfortable with T+1 settlement rather than T+0.
The most significant structural development in tokenized treasuries is their adoption as on-chain collateral. This is what distinguishes them from simply being a yield product — they have become infrastructure for the DeFi ecosystem.
| Protocol / Use case | BUIDL | OUSG | USTB |
|---|---|---|---|
| Lending collateral | Widely accepted | Flux Finance | Growing |
| Stablecoin backing | Ondo USDY, others | Limited | Limited |
| Treasury management | DAO treasuries | DAO treasuries | Some DAOs |
| Margin / derivatives | dYdX, Synthetix | Limited | Limited |
| Structured products | Principle component | Growing | Early |
| Cross-chain use | Ethereum primary | Ethereum, Polygon, Solana | Ethereum only |
BUIDL has become the de facto on-chain T-bill standard for DeFi infrastructure. Its brand credibility means protocols that integrate BUIDL face less institutional pushback. Ondo OUSG has carved out a specific niche as the DeFi-native distribution layer — lower minimums, multi-chain, deep protocol integrations on Flux and Compound. Superstate USTB is growing its DeFi footprint but is currently the weakest of the three in protocol integration.
You are an institutional investor with $5M+ to deploy. Your investment committee requires tier-1 brand and BNY custody. You want BUIDL as collateral infrastructure for DeFi protocols you operate. You have a Securitize account and can handle the KYC requirements.
You are a DeFi protocol, DAO treasury, or accredited investor who wants T-bill yield integrated into DeFi workflows. You need multi-chain support or $500+ minimum. You want instant USDC redemption without the $5M BUIDL minimum. You’re comfortable with the additional Ondo counterparty layer.
You want direct T-bill exposure without an intermediate fund wrapper. You value SEC-registered fund status over Reg D. You’re a crypto-native accredited investor comfortable with T+1 settlement. You prefer the team credentials (a16z, ex-Compound) and want to support a genuinely independent issuer.
All three products deliver what they promise — on-chain exposure to US T-bill yields. The differences are in access, counterparty structure, DeFi composability, and regulatory positioning. BUIDL wins on institutional credibility. OUSG wins on DeFi integration and accessibility. USTB wins on regulatory clarity and direct exposure. For most DeFi protocols and crypto-native funds, OUSG is the pragmatic choice. For institutional capital that needs to justify the investment to a traditional investment committee, BUIDL is the only realistic option.
