What is USD0?
Usual USD (USD0) is a next-generation, decentralized stablecoin pegged 1:1 to the U.S. Dollar. Unlike traditional stablecoins like USDT or USDC, which generate billions in interest for centralized companies, USD0 is part of the Usual Protocol—a decentralized infrastructure that redistributes 100% of its value and governance to the community. At its core, USD0 is a "Liquid Deposit Token" (LDT). It is fully collateralized by ultra-short-term Real-World Assets (RWAs), primarily U.S. Treasury Bills and overnight repurchase agreements. The protocol acts as an aggregator of top-tier tokenized treasuries (from providers like BlackRock, Hashnote, and Ondo), creating a unified, highly liquid dollar asset that is "bankruptcy-remote" from the traditional banking system. Usual's mission is to "rebuild the Tether model on-chain," ensuring that the users who provide the liquidity are the same ones who own and govern the protocol.
History & Origin
The development of Usual is the story of professional finance veterans seeking to democratize the "risk-free rate" of the U.S. dollar. Key historical milestones: * **The Origins (2022-2023)**: Founded in France by a team of finance and tech experts, Usual Labs spent nearly two years in research and development to create a legal and technical framework that allows for a truly decentralized, RWA-backed issuer. * **Strategic Funding (April 2024)**: The protocol secured $7 million in funding led by Kraken Ventures and IOSG Ventures, with participation from over 15 high-profile institutional investors, signaling massive confidence in the "Community-Owned Stablecoin" model. * **Launch & Growth (May-December 2024)**: USD0 was officially launched, quickly amassing over $2 billion in total value locked (TVL) as users flocked to a stablecoin that offered both the safety of Treasuries and the rewards of protocol ownership. * **The Unification Era (Late 2025)**: Usual expanded into a multi-currency ecosystem, launching **EUR0** (Euro-backed) and **ETH0** (Ethereum-backed), all governed by the same decentralized architecture. * **The Pivot to Usual Credit (2026)**: The protocol evolved from a simple stablecoin issuer into a full "DeFi-Fintech" neobank, acquiring lending protocols to offer fixed-rate credit against USD0 and its staked versions. Historically, Usual is recognized as the project that "socialized the yield" of the dollar, proving that stablecoin reserves can be a public good rather than a private corporate profit engine.
Utility & Use Cases
The utility of **USD0** and its ecosystem tokens follows a "Stake-to-Own" architecture. Key utility pillars include: * **The Stable Gateway (USD0)**: USD0 is a permissionless, composable ERC-20 token used for payments, as high-quality collateral in DeFi lending (like Morpho or Euler), and as a base pair for decentralized trading. * **Yield Generation (USD0++)**: USD0 holders can "upgrade" to **USD0++**, a Liquid Staking Token (LST). By locking USD0 for a fixed period (typically 4 years), users earn daily rewards in the form of USUAL tokens, effectively capturing the protocol's growth. * **Institutional-Grade Safety**: Because it is backed by Treasury Bills rather than commercial bank deposits, USD0 serves as a "Safe Haven" during banking crises, offering a direct claim on sovereign-grade collateral. * **The USUAL Token Utility**: * **Ownership**: USUAL represents a pro-rata share of the protocol's future revenues. * **Governance**: Holders vote on everything from collateral types to fee structures and reward emissions. * **Staking (USUALx)**: Staking USUAL into USUALx allows holders to receive weekly revenue shares from the protocol's Treasury management. * **Cross-Chain Interoperability**: Utilizing LayerZero technology, USD0 moves seamlessly across Ethereum, Arbitrum, Base, and BNB Chain, serving as a unified liquidity layer for the multi-chain world.
Tokenomics & Supply Model
Usual employs a "Revenue-Responsive" tokenomics model, where the growth of the governance token is mathematically tied to the success of the stablecoin. Economic Structure: * **USD0 Supply**: Elastic and demand-driven. 1 USD0 is minted for every $1 of approved RWA collateral deposited. * **USUAL Max Supply**: Capped at **3,000,000,000 (3 Billion)**. * **Community-First Allocation**: In a radical departure from traditional "VC-heavy" projects, **90% of USUAL tokens** are allocated to the community, with only 10% reserved for the founding team and early investors. * **Disinflationary Emissions**: The minting rate of USUAL adapts to market conditions. As more USD0 is minted and the protocol generates more interest revenue, the "cost" of emitting new USUAL tokens is carefully managed to ensure long-term value accrual. * **Revenue Sharing**: 30% of the interest generated by the underlying Treasuries is distributed to USUALx stakers, while 70% is reinvested into the DAO treasury to expand the collateral base.
Technical Architecture
The technology of Usual is a "Decentralized Minting Engine" that bridges institutional assets with on-chain transparency. * **Aggregated Collateral Module**: Usual does not rely on a single issuer. Its smart contracts aggregate tokenized T-Bills from multiple providers (BlackRock BUIDL, Ondo IUSG, Hashnote USYC), creating a "de-concentrated" reserve that minimizes third-party risk. * **The "Mint Engine"**: A custom-built system that manages the 1:1 swap between RWA tokens and USD0. It ensures that for every USD0 in circulation, a corresponding $1 of yield-bearing collateral is locked in the protocol. * **Proof of Reserve (PoR)**: Usual provides real-time, on-chain transparency. Anyone can verify the exact amount of Treasury Bills backing the supply at any moment, eliminating the "black box" risks associated with traditional stablecoin issuers. * **Parity Arbitrage Right (PAR)**: A governance-controlled "fail-safe." If the staked version (USD0++) ever trades significantly below its intended value, the DAO can trigger the PAR to restore the peg by allowing early redemptions under specific conditions. * **Liquid Staking Architecture**: The separation of USD0 (the stable asset) and USD0++ (the yield asset) allows users to remain liquid while still benefiting from long-term protocol rewards, a model inspired by Lido’s stETH.
Ecosystem & Adoption
The Usual ecosystem is a "Circular Value Loop" involving the best of TradFi and DeFi. * **RWA Providers**: Partnerships with **BlackRock, Ondo, and Hashnote** ensure that the collateral backing USD0 is of the highest institutional quality. * **Security Partners**: The protocol has undergone multiple audits by top-tier firms like **Runtime Verification and PeckShield**, ensuring the safety of the billions in deposited assets. * **DeFi Integrations**: USD0++ and USD0 are integrated into major yield optimizers and lending markets, allowing users to stack USUAL rewards on top of other DeFi yields. * **Usual DAO**: The ultimate authority of the network, where USUAL holders decide the future of "Community Finance." * **The Neobank Vision**: With the launch of **Usual Credit**, the ecosystem now offers the full suite of financial services—savings (sUSD0), credit, and investment—all on a decentralized, community-owned foundation.
Risk Assessment & Challenges
Usual operates in the **"Convergence Zone of Regulation and Innovation."** The primary risk is **"Custodial Risk."** Even though the tokens are on-chain, the physical Treasury Bills are held by traditional financial custodians. Any failure in the legal or physical custody of these assets could impact the value of USD0. **"Regulatory Shift"**: As a stablecoin backed by securities (T-Bills), Usual must constantly adapt to global laws (like MiCA in Europe or the US Stablecoin Acts). Changes in how RWA tokens are classified could affect the protocol's ability to accept certain collateral. **"Peg Maintenance"**: While USD0 is 1:1 backed, secondary market fluctuations can cause temporary de-pegging. The protocol relies on arbitrageurs and the GSM (Stability Module) to bring the price back to $1.00. **"Smart Contract Complexity"**: The interaction between multiple RWA tokens, liquid staking derivatives, and governance-driven minting creates a larger attack surface than a simple stablecoin. **"Yield Dependency"**: The attractiveness of the USUAL rewards depends on the interest rates of U.S. Treasuries. If global rates drop to zero, the protocol must find new revenue streams to maintain its value proposition. For the visionary user, USD0 is a "Bet on Financial Democracy"—the belief that the most successful digital dollar will be the one owned by its users, not a bank.
