# Why USDC?

OLTA is built around **USDC** to provide a stable, transparent, and interoperable foundation for on-chain structured investment products.

Unlike volatile base assets, USDC enables **clear, auditable pricing** and **efficient capital flows**, which are essential when modeling Net Asset Value (NAV), executing automated transactions, and minimizing operational risk.

**Each month**, Circle publishes **attestations verified by Deloitte**, a Big Four accounting firm, confirming that **USDC is fully backed 1:1 by cash and short-dated U.S. Treasuries**.\

Circle also partners with **BlackRock** (managing the Circle Reserve Fund) and **BNY Mellon** (custodian), reinforcing the institutional-grade infrastructure backing USDC.\

USDC’s **regulatory alignment**, widespread **DeFi integration**, and compatibility with **institutional custody standards** make it the ideal settlement layer for OLTA’s indexing logic.

By anchoring to a trusted and regulated stablecoin, OLTA simplifies user experience while enabling **cross-platform composability** and **future-proof integrations** across crypto-native and traditional finance applications.

#### Openness to Other Stablecoins

While **USDC** is the native settlement layer for OLTA, the protocol remains open to strategic partnerships with other stablecoins such as **USDT** or **USD1** (World Liberty Financial), which has generated strong institutional interest and attractive funding opportunities.

OLTA will align itself only with the **most relevant and robust partnerships** presented to it, ensuring every integration contributes to a stronger, more resilient, and institutionally aligned ecosystem.
