Welcome to Perena: Your Risk Layer on SolanaPerena is a decentralized financial protocol on Solana that offers USD STAR (USD*), a yield-bearing asset. Welcome to Perena : Your Risk Layer on Solana Perena is a decentralized financial protocol on Solana that offers USD STAR (USD*), a yield-bearing asset. 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. Perena is founded by a team of builders from the Solana ecosystem with backgrounds in TradFi and DeFi. We believe deeply in pushing financial architecture forward — and in doing it with transparency, resilience, and speed. We’re backed by some of the best in the world, including: Solana co-founders Anatoly Yakovenko and Raj Gokal Investors from Citadel, Jane Street, IMC, and Susquehanna Borderless Capital, Binance Labs, Primitive Ventures, Maelstrom, Anagram, Breed, and others Perena was a sponsor of the Colosseum Hackathon Stablecoin Track , helping fund the next generation of stablecoin projects on Solana. Our growing community spans over 20,000 developers, users, and builders aligned around one goal: reinventing how money works.
