# Why USDa Stands Out

### Fixed Borrowing Rate

**USDa** introduces a groundbreaking, fixed borrowing rate system, the first of its kind in DeFi, inherited from Avalon’s CeDeFi Lending platform. This unique feature offers users predictable capital costs, allowing them to easily forecast returns from on-chain activities, enhancing financial planning, and providing transparency.

### Sustainable Yield

**USDa**  holders can stake their assets in Avalon’s Yield-Generation Vault to earn a sustainable yield. This yield is supported by USDa’s borrowing rate and the revenue generated through USDaLend, ensuring long-term scalability and stability for users.

### Reliable 1:1 Conversion to USDT

Unlike traditional CDPs, USDa creative feature ensures a stable peg by allowing users to convert their USDa into USDT at a 1:1 ratio. This mechanism provides stability and protection against market volatility, eliminating the risks associated with de-pegging. USDa acts as a loan token within Avalon’s CeDeFi lending infrastructure, enabling users to claim USDT directly from our CeFi liquidity providers.

### Unlimited Supply

**USDa** is the only stablecoin that has no supply cap, giving it the flexibility to scale according to demand. Unlike other CDP-based stablecoins that struggle to maintain their peg due to supply constraints, USDa ensures continuous liquidity and stability without facing these limitations.

### Omnichain Compatibility

Powered by **LayerZero**, **USDa** is an omnichain stablecoin, offering users seamless access across multiple DeFi ecosystems. This cross-chain compatibility allows users to easily interact with **USDa** on a variety of blockchains without restrictions.

### Maximized Capital Efficiency

Avalon’s DeFi platform provides **USDa** access to a growing user base of over 200,000. With an isolated pool designed to maximize capital efficiency and minimize risks, **USDa** offers one of the most efficient and secure stablecoin solutions available.
