Why eligibility matters more than headline APY
Tokenized US Treasury products have grown into a real category. The combined assets of the four names you'll see on every yield dashboard, USDtb, BUIDL, OUSG, and USYC, now run into the billions of dollars. All four advertise yield profiles tied to short-term US Treasury rates, generally in the 4-5% range as of 2025. From a distance, the four look interchangeable.
They are not. The differences that actually decide whether you can hold one show up at onboarding, not in the marketing copy. Three of the four require KYC, accreditation, and minimum subscriptions that begin in the high five figures and climb into the millions. The fourth, USDtb, is built on stablecoin rails and is meaningfully more accessible to non-US retail users through DeFi protocols.
This article therefore leads with eligibility, not with yield. Readers who can't satisfy the gate shouldn't spend time comparing two APYs they can't actually earn. They should focus on the one wrapper that fits their jurisdiction and account size, and on the structural risks that affect every token in the category.
What each token actually is
Each of the four tokens is a private credit instrument with a different legal and operational wrapper. The wrapper matters because it determines who can hold the token, how it redeems, what jurisdiction's rules apply, and whether it can be freely transferred on public infrastructure.
BUIDL (BlackRock USD Institutional Digital Liquidity)
BUIDL is BlackRock's tokenized money-market fund. Each token represents a share in a fund that holds short-dated US Treasuries, cash, and repurchase agreements. The token is issued on Ethereum and is distributed through Securitize, which acts as the transfer agent and runs the KYC/AML pipeline. Because BUIDL is a fund share, every transfer is gated through Securitize's whitelist. You cannot send BUIDL to an arbitrary wallet; the recipient must already be onboarded.
OUSG (Ondo US Dollar Yield)
OUSG is Ondo Finance's tokenized short-term Treasury exposure. It is structured as a feeder into underlying short-duration Treasury products, originally Apollo's managed accounts. OUSG has been deployed on Ethereum, Mantle, and Solana. Like BUIDL, it is a fund-shaped wrapper: the token is a transferable security claim, and Ondo runs the onboarding and transfer permissions. Minimums historically began at $250,000, with minimum subscriptions to the underlying fund higher.
USYC (Hashnote Short Duration Yield Coin)
USYC is issued by Hashnote and is structured as a money-market-style tokenized fund backed by short-duration US Treasuries and reverse repo. Hashnote has positioned USYC as a more accessible Treasury-yield instrument, but the token still sits inside a regulated wrapper that requires investor onboarding. Direct subscriptions historically run from $250,000 upward, with significant KYC and accredited-investor checks.
USDtb (Ethena's Treasury-Backed Stablecoin)
USDtb is the outlier. It is issued by Ethena Labs in partnership with Anchorage Digital Bank and is engineered to behave like a stablecoin: a 1:1 dollar token that holders can use across DeFi. The backing, however, is not pure fiat reserves. USDtb holds a mix of tokenized money-market funds (including allocations to BUIDL and other BlackRock and Treasury-related products), reverse repurchase agreements, US Treasuries, and cash equivalents. It is a stablecoin-shaped wrapper around a Treasury-heavy portfolio, not a pure money-market fund.
Backing and underlying portfolio composition
All four tokens share the same basic payoff logic: short-term US Treasury yields, with credit exposure to the US government and counterparty exposure to the banks and intermediaries that sit between the holder and the underlying bonds. The differences are in the wrapper and the operational plumbing.
What BUIDL, OUSG, and USYC actually hold
Each of the three fund-shaped wrappers holds short-dated US Treasuries (typically under 13 weeks to maturity), reverse repo backed by Treasuries, and US dollar cash. The portfolios are kept rolling so that interest income is reflected in the token's net asset value rather than distributed as coupons. NAV per token is published daily, and any deviation between market price and NAV is typically a basis-trading opportunity rather than a structural arbitrage.
What USDtb actually holds
USDtb's reserves are held by Anchorage Digital Bank and consist of a mix of tokenized money-market funds (which themselves hold Treasuries and repo), direct reverse repo, US Treasuries, and US dollar cash. The published composition has shifted as Ethena has rebalanced across counterparties. The key point is that USDtb deliberately pools access to fund-shaped wrappers that retail users would otherwise be gated out of, and wraps the result in a stablecoin token that can move on permissionless rails.
Why the difference matters
Fund-shaped wrappers give you a direct legal claim on a custodian pool. Stablecoin-shaped wrappers give you a claim on the issuer's reserves, which is one remove from the underlying assets. The former is closer to owning a regulated fund share; the latter is closer to holding a regulated bank liability. Both have a place, but the risk profile is different.
Risks and gotchas that don't show up on the dashboard
Every tokenized Treasury product carries a stack of risks that the headline APY doesn't show. Some are common to all four. Some are specific to one wrapper or one jurisdiction.
Counterparty risk: the bank in the middle
Even when the underlying assets are US Treasuries, the access path runs through banks, custodians, fund administrators, and tokenization platforms. A failure at any of those intermediaries can freeze redemption or impair value. Historical examples include money-market fund breaks during the 2008 crisis and the 2023 US regional banking stress, when even short-term Treasuries saw temporary dislocation. Tokenized wrappers add tokenization-specific counterparties (Securitize, Ondo, Ethena, Anchorage, Hashnote) on top of the traditional stack.
Depeg risk: stablecoin-shaped wrappers
USDtb is designed to maintain a 1:1 dollar peg, but the peg is only as strong as the issuer's ability to redeem on demand. If on-chain liquidity thins, if the issuer's reserve composition comes under scrutiny, or if a regulation-driven run hits the category, USDtb can trade below $1. The 2022 TerraUSD collapse and the 2023 USDC depeg to $0.87 are the cautionary examples. Neither was a Treasury-backed token, but both show how stablecoin-shaped wrappers can fail in ways that fund-shaped wrappers, which price to NAV, do not.
Regulatory risk: changing definitions
The legal status of each token can change. The SEC has historically taken the view that fund-shaped wrappers like BUIDL, OUSG, and USYC are securities, which is why they sit behind KYC and accredited-investor gates. Stablecoins have been treated inconsistently, and the GENIUS Act has now created a federal payment-stablecoin regime. Regulators can also change the rules for who can hold a token, which can render positions illegal or illiquid overnight.
Smart-contract and operational risk
Every token here moves on-chain, which means smart-contract bugs, oracle failures, and bridge exploits are part of the risk surface. Even permissioned tokens like BUIDL and OUSG rely on smart contracts for issuance and transfer. Vaults and lending markets that accept these tokens as collateral layer on additional risk.
Concentration and exclusivity risk
Several of these products depend on a single fund administrator or a single banking partner. Concentration in any one of these counterparties is a hidden risk. If a key partner exits the business, the token may have to migrate to a new structure, which can take months and disrupt holders.
Redemption terms, minimums, and frequency
The operational differences between the four tokens often matter more than the headline yield, because redemption is where holders actually experience the product.
BUIDL
BUIDL redemptions are processed in USDC through Securitize's infrastructure. Eligible holders can redeem daily, subject to a minimum redemption size and standard banking cut-off times. The token does not pay yield directly; instead, the NAV accrues and the value of each token rises. Underlying minimums for direct subscription historically sit at $5 million, though access through feeder funds and partner platforms can lower the entry point for some qualified investors.
OUSG
OUSG follows a similar daily-redemption model, with redemption processed through Ondo's infrastructure. The token accrues value to NAV and does not distribute yield separately. Minimum subscription sizes depend on the distribution channel, with direct subscriptions historically starting around $250,000.
USYC
USYC offers daily redemption, with NAV accrual. Hashnote has differentiated by offering both on-chain and traditional rails, and by working with distribution partners to lower minimums. Even so, the underlying product is fund-shaped and gated behind KYC.
USDtb
USDtb is meaningfully different operationally. Because it is a stablecoin-shaped wrapper, holders can redeem 24/7 by routing through Ethena's infrastructure or by exiting on the open market through DeFi venues. There is no fund-level minimum for token-level transfers. The cost of redemption is the network gas and any slippage in the destination venue.
Why this matters
If you need daily liquidity, all four can deliver it through their official channels. If you need weekend liquidity, instant liquidation, or the ability to move collateral into a lending market without permission, USDtb is the only one of the four that gives you stablecoin-style behavior. That operational difference is the single biggest practical reason USDtb has found product-market fit while the fund-shaped wrappers remain institutional distribution products.
The GENIUS Act and the regulatory shift
The Guiding and Establishing National Innovation for US Stablecoins (GENIUS) Act, signed into law in 2025, created the first federal payment-stablecoin regime in the United States. The framework sets 1:1 reserve requirements, mandatory monthly disclosures, and a clear licensing path for issuers. The implications for tokenized Treasury products are large.
What changes for stablecoin-shaped wrappers
USDtb and any other stablecoin-shaped wrapper that targets payment use cases now has a clear path to federal compliance, but also a clear set of obligations. Issuers must demonstrate 1:1 backing with low-risk assets, mostly short-term Treasuries and cash, and must publish monthly reserve attestations. This is a tightening of the rules but also a major legitimacy upgrade. The institutional distribution that previously shied away from unregulated stablecoins now has a clearer federal framework to work with.
What changes for fund-shaped wrappers
BUIDL, OUSG, and USYC sit under existing securities and investment-company rules rather than the new GENIUS regime. The GENIUS Act does not directly subordinate them, but it does create a competing federally regulated alternative. Over time, some institutional investors may prefer the cleaner regulatory status of a GENIUS-compliant stablecoin, especially for payment and settlement use cases, while continuing to use fund-shaped wrappers for treasury-yield exposure.
Cross-border implications
Outside the United States, the GENIUS Act does not directly apply, but it sets a regulatory template that other jurisdictions are likely to borrow from. For non-US retail users, this likely means more choices over time but also more rules about which tokens can be held and which platforms can be used.
Practical implications for the reader
The right token for you depends on jurisdiction, account size, and use case. Here is how to think through it without overpromising returns.
If you are a US retail investor
You can access USDtb through DeFi protocols that support it, but you will face the same on-chain and tax considerations as any other stablecoin. BUIDL, OUSG, and USYC require accredited or institutional status, and you should not attempt to work around those gates. The accreditation rules exist for a reason, and the registration gates are part of what gives the products their legal status.
If you are a non-US retail investor
USDtb is generally the most accessible of the four, but local rules still apply. Some jurisdictions restrict or prohibit access to US-dollar stablecoins, and others require registration of the platform that hosts them. Confirm with a local advisor before making any transaction.
If you are an institutional allocator
You probably have direct access to BUIDL, OUSG, and USYC through fund or wealth channels. The decision framework is then about which product offers the best operational fit: NAV approach, redemption timing, transfer permissions, and integration with your existing fund administrator. Yield is the smallest differentiator.
If you are a DeFi user
USDtb is the only one of the four that moves on permissionless rails in a way that integrates with major lending markets and DEXes. Liquidity is the key variable. Before treating USDtb as equivalent to USDC, check the depth of the liquidity pool and the redemption path through Ethena's infrastructure.
The general rule
If you can't satisfy the gate, you shouldn't hold the gated product. If you can, compare the wrappers on operational fit and on the legal claim you are actually buying, not on the headline APY, which is set by the underlying Treasury rate and is roughly the same across all four.
How to follow tokenized treasuries the smart way
Tokenized Treasury products move with the broader rate environment, but the regulatory and operational landscape shifts quickly. The category is young, and the rules of the game are still being written. Manually tracking issuer disclosures, NAVs, and policy updates is a losing game for any individual reader. Zippfeed surfaces tokenized Treasury headlines with sentiment scoring (bullish, neutral, or bearish) and an importance rating, so you can spot the changes that actually matter to your position before they hit your inbox.
