DATs vs Stablecoins vs Tokenized Treasuries: What is Actually Different?

Why these three products keep getting mixed up

On a trading screen, a share of MicroStrategy, a USDT token, and a BUIDL token can all be priced roughly in dollars per coin. The logos look similar, the tickers overlap with stablecoin-like names, and the marketing language uses the same words: backed, redeemable, transparent. Many newer readers assume they are flavors of the same product.

They are not. Each one sits in a different legal box. A DAT is corporate equity traded on a stock exchange. A stablecoin is a private liability issued by an offshore or domestic company. A tokenized T-bill fund is a regulated fund share, often issued by a real asset manager such as BlackRock or Ondo, and recorded on a blockchain for faster settlement. The shared feature is that the price is meant to be steady, not that the legal mechanics are the same.

Confusing the three matters because the failure modes are different. If a DAT's stock price falls 40 percent, the company is still operating. If a stablecoin breaks its peg, holders may not be able to redeem at par. If a tokenized fund's underlying Treasury is fine but the issuer pauses redemptions, holders face a queue, not a bankruptcy claim. The risks and the rights are not interchangeable.

What a digital asset treasury company actually is

A digital asset treasury company, or DAT, is a publicly traded corporation whose main job is to hold a reserve asset, most often Bitcoin, on its balance sheet. MicroStrategy (now rebranded Strategy) is the template, and dozens of imitators followed, including Marathon, Riot, Block, Tesla for a time, and a wave of smaller companies that raised convertible debt to buy crypto. The shares trade on regular equity markets under normal ticker symbols, and the price moves with the underlying crypto holding plus a leverage premium or discount.

When you buy a DAT share, you are buying equity, not a dollar claim. You are not promised one dollar back. You own a slice of a company that owns coins, and your return is the company's stock price, which can swing 50 percent in a week. Some DATs also run operating businesses such as mining or software, which adds a second layer of business risk on top of the crypto exposure.

The right you have is the same right any common shareholder has: voting, dividends if declared, and a residual claim in liquidation after creditors. If the company goes bankrupt, coin holders do not lose the Bitcoin itself, which sits with a custodian. But shareholders are last in line, the bankruptcy process takes years, and the share price can collapse long before the legal wind-down finishes. Calling a DAT a stablecoin, or treating it like a tokenized Treasury, ignores all of this.

What a stablecoin actually is

A stablecoin is a token issued by a private company, designed to hold a stable value, usually one US dollar. The two largest are USDT from Tether and USDC from Circle. Each token represents a liability of the issuer, similar to a prepaid card balance or a money-market deposit at a fintech. The issuer promises to redeem the token for one dollar (or for the underlying asset) and earns the spread on the reserves it holds to back that promise.

Reserves vary widely. A well-run fiat-backed stablecoin holds short-dated US Treasuries, cash at banks, and reverse repurchase agreements. A riskier one may also hold commercial paper, certificates of deposit, secured loans, or even other crypto. Tether's reserves have historically included a meaningful slice of non-Treasury assets, and the company publishes attestations rather than full audits, which is a meaningful distinction for institutional users.

Redemption is the key word. Most retail users cannot redeem USDT directly with Tether. Instead, they sell on the open market, which works fine in calm conditions but breaks down in a panic, as it did briefly during the March 2023 USDC depeg after Silicon Valley Bank failed. Circle held $3.3 billion at SVB, and USDC traded down to 87 cents before recovering. Anyone who treated USDC as equivalent to a bank deposit learned an important lesson that week.

What a tokenized T-bill fund actually is

Tokenized T-bill funds, sometimes called NAV tokens, are shares in regulated money-market funds that hold short-term US government debt. The fund is a real legal entity, typically a Cayman or Delaware trust, and the manager is a registered investment adviser. BUIDL is run by BlackRock, USDY and OUSG by Ondo Finance, USYC by Hashnote, and USTB by Superstate. Each fund files public disclosures and operates under a fund prospectus with stated rules.

The token is essentially a fund share with a blockchain wrapper. Holders receive a net asset value that drifts by single basis points per day, the same way a traditional money-market fund drifts, and the yield comes from the underlying Treasuries and repo. Because the asset is a fund share, the price is not strictly one dollar the way a stablecoin is, which is why these products are often called NAV tokens rather than stablecoins.

Redemption rights depend on the fund, not on a public market. Most tokenized T-bill funds allow qualified holders to redeem directly with the manager, subject to a cut-off time, a minimum size, and standard settlement. Retail users on apps such as Ondo's own platform or integrated exchanges can usually subscribe and redeem in token form. In a stress event, redemptions still flow through the fund's rules, which include liquidity fees, redemption gates, and in extreme cases a suspension, the same tools any money-market fund has.

Side by side: what backs each, who can redeem, and what rights you have

Looking at the three products through the same five questions makes the differences concrete. The legal wrapper matters more than the underlying asset, which is the surprise most readers hit when they first compare them carefully.

What backs the token

• DAT: corporate balance sheet, mostly Bitcoin, plus any operating assets and liabilities such as convertible debt.
• Stablecoin: a mix of cash, short-dated Treasuries, repo, and sometimes riskier assets chosen by the issuer.
• Tokenized T-bill fund: short-term US Treasuries and reverse repo held inside a regulated fund vehicle.

Who can redeem and how

• DAT: not redeemable in any meaningful sense. Shareholders sell on the open equity market at whatever price the market sets.
• Stablecoin: only authorized redeemers can go directly to the issuer. Most users rely on secondary market liquidity, which depends on market makers and confidence.
• Tokenized T-bill fund: qualified holders can redeem directly with the fund manager under documented terms, subject to fund rules and cut-off times.

What rights the holder has

• DAT: equity rights, voting, dividends if any, and a residual claim in liquidation, behind every creditor.
• Stablecoin: a contractual right against the issuer, governed by the issuer's terms of service, often in a foreign jurisdiction.
• Tokenized T-bill fund: fund-share rights, with protections from the fund's legal structure, the manager's fiduciary duty, and securities regulations.

Where counterparty risk sits

• DAT: the corporation, its custodians, and its lenders who hold secured claims on the crypto.
• Stablecoin: the issuer, the custodian banks, the auditors, and the asset quality of the reserves.
• Tokenized T-bill fund: the fund manager, the custodian, the fund's board, and the underlying US government, which is the actual borrower on the Treasuries.

Where the real risks sit in each structure

Each product has a distinct failure mode, and confusing them is the easiest way to take the wrong kind of risk.

DAT-specific risks

• Leverage: many DATs raised convertible debt or preferred shares to buy crypto, which magnifies losses on the way down.
• Share price decoupling: the stock can trade at a discount to net asset value for months, locking holders into a falling price even if the underlying coins are stable.
• Business risk: a small DAT with a weak operating business can drop to near zero even if its Bitcoin holdings are intact.

Stablecoin-specific risks

• Reserve quality: opaque or risky reserves are the classic stablecoin failure mode, and history is full of examples, from the TerraUSD collapse in 2022, which wiped out roughly $40 billion in value, to smaller depegs on lesser-known issuers.
• Bank exposure: a custodian bank failure can temporarily break the peg, as USDC holders saw in March 2023.
• Regulatory risk: the issuer can be sanctioned, fined, or shut down, freezing redemptions, as happened to certain offshore issuers in past enforcement actions.

Tokenized T-bill fund risks

• Manager and custodian risk: smaller or newer managers carry operational and key-person risk, even when the underlying assets are safe.
• Liquidity tools: in a panic, the fund can impose redemption gates or fees, which is a feature of money-market regulation but still a risk to the holder.
• Smart contract and bridge risk: the on-chain wrapper can be hacked, and some tokens depend on bridges or custodial minting that add a layer of operational risk on top of the regulated fund.

What this means if you actually want exposure to short-term US debt

If the goal is yield on cash with minimum volatility, the cleanest path is still a tokenized T-bill fund from a large, regulated manager, combined with a direct US Treasury money-market fund or a brokerage sweep for the non-crypto portion of the portfolio. These products are designed for the use case and are usually held by institutional treasuries for that reason.

Stablecoins make sense for working capital, trading, and moving dollars quickly across crypto rails. They are not savings products, and treating them as such invites the kind of depeg risk that has played out several times. The yield some offshore stablecoins advertise often comes from the very reserve composition that creates the risk, which is worth keeping in mind.

DATs are a leveraged equity bet on the price of the underlying coin, nothing more. They are useful for investors who want equity-style exposure with stock-market mechanics, but the price action of a DAT share is closer to a leveraged crypto ETF than to a dollar-denominated instrument. Anyone who holds a DAT expecting dollar-like behavior is going to be surprised, and not in a good way.

Read dollar-pegged crypto products critically

Tokenized treasury funds, stablecoins, and DATs all sit near one dollar on a chart, but the legal claim behind each token is built on a different foundation. The fastest way to misunderstand any of them is to focus on the price and ignore the wrapper. Read the prospectus, the attestations, and the redemption terms before treating any token as cash. Education, not financial advice, is the right starting point for any of these products.
