Tokenized Treasuries Explained: On-Chain T-Bills for Beginners

Guide · 2 min read · · Reviewed by the Spield team

What are tokenized treasuries?

Tokenized treasuries are blockchain tokens that represent ownership of U.S. Treasury bills or money-market funds, backed 1:1 by the real securities held with a regulated custodian. They bring low-risk government-bond yield on-chain with 24/7 settlement and fractional access, and are one of the fastest-growing real-world-asset categories in crypto.

Key takeaways

  • Tokenized treasuries = U.S. T-bill exposure as a blockchain token, backed 1:1 by real securities.
  • A custodian holds the bills; a smart contract mints tokens; an oracle updates the value.
  • They offer government-bond yield (recently ~3–5%) with 24/7, fractional on-chain access.
  • Examples: BlackRock BUIDL, Ondo OUSG/USDY, Franklin BENJI.
  • They are a type of real-world asset (RWA) and a cousin of on-chain fixed income.

How do tokenized treasuries work?

  1. The issuer buys the securities

    A regulated issuer buys short-term U.S. Treasuries or shares of a money-market fund.

  2. A custodian holds them

    The real securities are held by a regulated custodian, keeping the token backed 1:1.

  3. A smart contract mints tokens

    On-chain tokens are minted to represent claims on the underlying, often restricted to eligible investors.

  4. An oracle updates value

    An oracle updates the net asset value (typically daily) so the token reflects accrued yield.

Why do tokenized treasuries matter?

Tokenized treasuries matter because they let on-chain capital earn safe, familiar government-bond yield without leaving the blockchain. Instead of holding idle stablecoins, a crypto treasury or investor can hold a token that pays T-bill yield, settles instantly, trades 24/7, and can be composed into DeFi — for example as collateral.

Are tokenized treasuries safe?

Tokenized treasuries are backed by some of the lowest-risk assets in the world (short-term U.S. government debt) held with regulated custodians, which makes their underlying very safe. The added risks are on-chain risks — smart-contract bugs, oracle/NAV accuracy, issuer and custody counterparty risk, and access restrictions or redemption gates. The underlying is low-risk; the wrapper introduces new considerations.

What is the difference between tokenized treasuries and stablecoins?

A stablecoin holds its value at $1 and usually pays no yield to the holder, while a tokenized treasury pays the yield of the underlying Treasuries. Both can be backed by similar assets, but tokenized treasuries pass the interest to you.

Are tokenized treasuries available on Stellar?

Yes — Stellar hosts tokenized real-world assets, including Franklin Templeton’s BENJI money-market fund. See our guide to RWAs on Stellar for how they fit the ecosystem.
