Usual USD (USD0)

Overview

Usual USD, known by its ticker USD0, is a digital token designed to track the value of one U.S. dollar. It is part of the Usual protocol, which connects assets from traditional finance with blockchain applications. USD0 is backed by tokenized financial assets, mainly short-term U.S. Treasury bills. Tokenization means representing an asset through a digital token that can be used on a blockchain. (docs.usual.money)

USD0 has a different job from USUAL, the protocol’s governance token. People use USD0 as a dollar-denominated asset for transfers, trading, and decentralized finance, or DeFi. USUAL gives holders a role in protocol decisions and its reward system. Understanding this difference makes the rest of the Usual ecosystem easier to follow. (docs.usual.money)

History & Team

From Usual Labs to the DAO

Usual Labs was founded in France in 2022 by Pierre Person, Adli Takkal Bataille, and Hugo Sallé de Chou. Person is a former member of France’s National Assembly. The team developed Usual around an idea: a stablecoin protocol could let its users take part in governance and share in the value produced by its reserves. (prnewswire.com)

USD0 launched in May 2024. Usual Labs raised a seed round led by IOSG Ventures and Kraken Ventures in 2024, followed by a Series A led by Binance Labs and Kraken Ventures. Other backers named by the project include Coinbase Ventures and Galaxy Ventures. These firms backed the project’s development; they are distinct from the Treasury-backed assets that support USD0. (docs.usual.money)

The project later shifted more control to the Usual decentralized autonomous organization, or DAO. A December 2025 governance decision placed protocol assets under DAO ownership, with Usual Labs serving as a contributor. The DAO governs protocol matters, while Usual Labs remains a separate company with its own corporate leadership. (docs.usual.money)

Technology & How It Works

Turning collateral into USD0

USD0 is an ERC-20 token, a common format for digital assets on Ethereum. Usual also supports it on Arbitrum, Base, and BNB Chain. Its backing comes through tokenized assets tied to short-duration government instruments. Usual identifies Hashnote’s USYC, M^0’s M token, and Spiko’s USTBL among its eligible collateral sources. This approach lets the protocol work with financial assets through blockchain-based records and smart contracts. (docs.usual.money)

There are two main routes for creating USD0. In the direct route, a participant deposits an eligible collateral token and receives USD0. Returning USD0 through that route releases the corresponding collateral. In the indirect route, a user supplies USDC and a collateral provider supplies the eligible backing. The provider receives the USDC and protocol incentives. Smaller indirect orders are directed toward secondary-market exchanges rather than that primary minting route. (docs.usual.money)

The system aims to keep USD0 near one dollar through minting, redemption, and trading. When a token trades away from its target, participants with access to the primary routes may have an incentive to exchange between USD0 and its backing. Usual also uses a multi-collateral controller to adjust incentives across collateral providers. On-chain price information helps the contracts value the assets involved. (docs.usual.money)

USD0 can move between supported wallets and DeFi applications like other compatible tokens. The underlying Treasury assets follow a different process: their custody and settlement involve financial institutions and asset tokenizers. Usual’s collateral framework calls for liquid assets with a maximum redemption horizon of five business days. In this way, the blockchain token provides an on-chain dollar unit while drawing its backing from financial markets. (docs.usual.money)

Tokenomics & Utility

Three tokens, three roles

The supply of USD0 grows when eligible collateral enters the system and falls when tokens are redeemed and burned. It has no fixed maximum supply. Its economic model centers on maintaining backing for the tokens issued, rather than releasing a preset number of USD0 over time. Holding ordinary USD0 serves the stablecoin’s transfer and DeFi functions; the protocol’s reward features sit in related products. (docs.usual.money)

One of those products is bUSD0, the bonded form of USD0 previously called USD0++. Locking USD0 creates bUSD0 and a separate token, rt-bUSD0, that represents an early-exit right. bUSD0 earns USUAL rewards. The two tokens can be brought together to redeem the locked USD0 before maturity under the product’s rules; bUSD0 is also designed to convert back at maturity. Its market value may differ from USD0 because the lock and exit right are separate. (usual.money)

USUAL supports governance and incentive distribution. Holders can participate in decisions about matters such as collateral, fees, and other protocol settings. Locked USUAL, called USUALx, participates in the protocol’s revenue-sharing system. A November 2025 governance vote reduced USUAL’s maximum supply from four billion to three billion tokens and changed its emissions. Those figures describe USUAL, not the USD0 stablecoin. (docs.usual.money)

Ecosystem & Use Cases

A dollar unit for on-chain finance

USD0 can act as a dollar-denominated unit within supported blockchain applications. Someone can transfer it to another wallet, exchange it for a different token, or use it in a DeFi service that accepts it. In a trading pool, for example, USD0 may be paired with another stablecoin so people can swap between them. Its ERC-20 format also allows applications to build transactions around it through smart contracts. (docs.usual.money)

Usual has built other services around that base. bUSD0 offers a way to lock USD0 for token rewards, while savings and credit products serve different purposes in the protocol. The project has also introduced euro-denominated products. A June 2026 update brought these services into a redesigned Usual app intended to put currencies, savings, and other functions in one account view. Each product has its own mechanics; USD0 remains the underlying dollar stablecoin in this part of the system. (docs.usual.money)

Advantages & Challenges

USD0’s main advantage is its combination of a dollar target with on-chain transferability. Its Treasury-based collateral gives users a defined way to understand where the backing comes from. Multiple eligible collateral sources can reduce reliance on a single tokenizer, while public smart contracts make token movements and some collateral information visible. The project has also commissioned independent reviews of its code. (docs.usual.money)

The design has several moving parts. Direct minting uses eligible tokenized assets that many everyday wallet users may not hold, while indirect minting depends on collateral-provider matching. Trades on exchanges occur at market prices, which can differ from the protocol’s one-dollar target. The stablecoin also connects on-chain contracts to off-chain custody and settlement, making both parts important to its operation. (docs.usual.money)

Governance brings another trade-off. USUAL holders can shape protocol settings, but changes to collateral rules, fees, or incentives can alter how people use the system. The contracts include controlled functions such as pausing transfers and restricting specified addresses. These features show that operating a stablecoin involves both community decisions and administrative controls. (docs.usual.money)

Where to Buy & Wallets

USD0 is available for swaps on Uniswap V3 and Curve on Ethereum, including pools paired with USDC. It can also be acquired through the Usual protocol’s minting routes when a participant has the required eligible assets and access. These are ways to obtain USD0; an exchange swap and a primary-market mint follow different processes. (docs.usual.money)

MetaMask can hold USD0 on a supported network. The Ethereum USD0 contract address is 0x73a15fed60bf67631dc6cd7bc5b6e8da8190acf5. A wallet needs the token on the same network as the USD0 being sent. Adding the correct network and token contract allows the wallet to display the balance and interact with compatible applications. (coingecko.com)

Regulatory & Compliance

Stablecoin rules depend on jurisdiction and on how a token is legally classified. In the European Union, the Markets in Crypto-Assets framework, or MiCA, sets requirements for issuers offering certain stablecoins to the public or seeking their admission to trading. Those rules include authorization and disclosure requirements. The legal status of a collateral tokenizer or custodian is a separate matter from the legal classification of USD0 itself. (esma.europa.eu)

In the United States, the GENIUS Act established a federal framework for payment stablecoins, with regulators working on its implementation. Usual’s published interface terms exclude U.S. residents and nationals from using its services. The protocol’s contracts also provide address-restriction controls for compliance purposes. These terms concern access to Usual’s interface and services; blockchain tokens can also circulate through other applications. (fdic.gov)

Shariah compliance raises a separate question from government regulation. Islamic finance generally prohibits riba, or interest. USD0’s reserve model uses conventional U.S. Treasury bills, and related products distribute rewards connected to the protocol’s economics. That interest-bearing backing is a central concern when assessing the system under Shariah principles. A dollar peg alone does not establish halal status; the reserve structure and the particular way a person uses USD0 or its related products both matter. (docs.usual.money)

Future Outlook

Usual has expanded from a single stablecoin into a group of currency, savings, and credit products. Its June 2026 app update reflects an effort to make those products work together through a simpler interface. For USD0, the lasting question is how well its collateral, redemption routes, and DeFi integrations serve people who want a usable on-chain dollar. DAO decisions will continue to shape the eligible backing and the incentives around it. (usual.money)

Summary

Usual USD is a Treasury-backed stablecoin built to bring a dollar-denominated asset into DeFi. USD0 handles the stablecoin role, while bUSD0 adds a locking feature and USUAL handles governance and incentives. Its place in the crypto ecosystem comes from linking tokenized traditional assets with blockchain transfers, trading pools, and a wider set of financial applications. (docs.usual.money)
