USD\* is fully collateralized and earns yield from diversified, real sources such as delta-neutral strategies and secured borrow-lend market positions. Its value grows automatically, making it a simple, secure way to save on-chain. USD\* is fully collateralized by a diversified portfolio of yield-generating assets and positions, including: * **Delta-neutral hedged positions** on centralized and decentralized exchanges (e.g., BTC, ETH, SOL) * **Secured borrow-lend market positions** involving on-chain stablecoins * **Real-world assets**, such as the reinsurance fund by OnRe Perena actively manages asset allocation and diversifies across multiple strategies to reduce single points of failure and optimize for sustainable, consistent yield performance. Built on Solana’s high-performance blockchain, Perena is creating a liquid, yield-bearing digital dollar that anyone can access with a sustainable, risk-managed approach. Looking ahead, Perena is building a full suite of on-chain stablebanking products to expand access to real yield across crypto and traditional finance. The goal is a sustainable financial experience for anyone to transact, save, and invest on-chain.
