Usual USD0 Review: Is This Treasury-Backed Stablecoin Worth Using?

Usual is a DeFi protocol built around USD0, a stablecoin described as backed 1:1 by a basket of tokenized short-term US Treasury bills. The project says USD0 is transferable and designed to work with DeFi and centralized finance. That makes it potentially useful as a stable-value asset for Ethereum activity, but it does not by itself establish which apps accept it or how easy it is to convert back to other assets.

USUAL is the protocol token, described as providing governance and revenue-sharing. Usual also presents bUSD0 as a yield-oriented version of USD0, with a four-year lock-up. Treat that as a separate product: access to funds, yield conditions and risks can differ from holding USD0. Yield optimizers, fixed rates and fixed terms are described as upcoming products, so do not assume they are currently available.

Usual does not publish a clear fee schedule for using USD0 in the product information reviewed here. Your actual costs will depend on how you get and use it. Swapping through a decentralized exchange can involve a trading fee and a difference between the quoted and executed price; Ethereum transactions also require gas, paid in the network’s native asset. A centralized venue may set its own fees and withdrawal terms.

The project does not clearly publish USD0’s redemption process, minimums, timing or any related charges. Do not assume that converting USD0 to dollars is as simple or immediate as swapping tokens on-chain. Before committing a substantial amount, check the current app instructions and any venue-specific terms, and estimate gas for both entering and leaving the position. Any displayed yield on bUSD0 should be assessed separately from the cost of holding USD0.

Usual says USD0 is backed by tokenized Treasury-bill assets and that protocol revenue funds an insurance pool. These are important claims, but tokenized government securities are not the same as a direct deposit or a Treasury bill held in your own name. Holders can still face risks involving the issuer, custodians, legal structure, redemption access, smart contracts and the stablecoin’s market price. An insurance fund should not be treated as a guarantee unless its coverage, limits and claim process are clear.

Two audits are listed for the protocol, and the project homepage displays audit-firm names. Audit count alone does not tell you which contracts were covered, when they were checked or whether issues remain. Usual does not publish its licence status in the product information reviewed here. A January 2025 report described a depeg involving USD0++, a separate product, following rule changes; this is not evidence that USD0 itself depegged, but it highlights the need to review each product’s terms independently.

Usual’s app is the stated entry point, and the protocol is classified for Ethereum. You will need an Ethereum-compatible wallet to interact with on-chain products, and transactions will require ETH for gas. The project describes USD0 as permissionless and composable, but does not clearly publish a complete guide to acquiring it, redeeming it, or the wallets and venues it supports. Confirm the current route in the app before signing transactions.

For a first interaction, check the token and network details against Usual’s official documentation, read every wallet prompt, and avoid approving permissions you do not understand. Try only an amount you can afford to have delayed or lose, and check the exit route before depositing or swapping. KYC requirements are not clearly published for the product, so review the app’s current rules rather than assuming that permissionless on-chain access means every service is available without identity checks.

The main gap for a cautious user is the lack of clear, readily stated details on redemption, fees and the legal arrangements behind the tokenized collateral. Those details matter more than the headline claim of 1:1 backing if you need to exit quickly or want to know what rights you have when something goes wrong. The project’s descriptions of USD0 as secure, fully collateralized and bankruptcy-remote should be checked against the actual contracts and legal documents before you rely on them.

Usual’s products also should not be treated as interchangeable. USD0 is the stablecoin; bUSD0 is described as a yield-bearing product with a four-year lock-up, and USD0++ has had a separately reported depeg episode. If you want simple cash-like access, predictable redemption, or a fully disclosed fee and licensing picture, choose a provider that publishes those terms clearly.
