Sierra
About
Sierra is a Liquid Yield Token (LYT) that provides intrinsic yield through a diversified portfolio of real-world assets (RWAs) and DeFi yield sources. It is designed as universally accessible, self-custodial money that appreciates in value over time, with yield compounded daily without lock-ups or staking requirements.
Where Does Yield Come From?
Sierra earns yield by investing its reserve assets into a dynamically managed mix of traditional real-world assets and decentralized finance (DeFi) opportunities.
The portfolio includes two main types of sources:
- Real-world assets (RWAs): U.S. Treasury money market funds and investment-grade commercial paper (high-quality short-term corporate debt).
- DeFi sources: Overcollateralized lending via Aave and Morpho (loans backed by more collateral than borrowed, curated by risk experts Gauntlet), and basis yield strategies via OpenTrade and Figment.
The portfolio is rebalanced daily based on market conditions. This aims to maintain liquidity, diversify risk, keep investments short-term (low duration), and enhance overall yield.
Yield accrues through price appreciation of the SIERRA token. As the underlying reserve assets grow, the exchange rate of SIERRA increases—your tokens become worth more over time. This method does not change your token supply (no rebasing).
The reserve strategy is overseen by an independent Board of Directors and an Advisory Council. The asset vaults are powered by OpenTrade's institutional-grade infrastructure for security and reliability.
