Solayer USD: Yield-bearing Real World Assets Backed Synthetic Stablecoin

Here you can access the sUSD litepaper, which provides detailed information about sUSD and its unique features.

​
Abstract

This paper introduces Solayer USD (sUSD), a dollar-pegged stablecoin backed by a basket of low risk profiled real world assets (RWAs), such as U.S. Treasury Bills, Bond, Gold etc, offering a secure 4-5% annual yield to holders through T-Bill-backed interest accrual initially. Utilizing Solana’s Token2022 extension [Sol24], sUSD’s protocol adjusts balance multipliers instead of token amounts, allowing holders to realize yield growth. Additionally, through a decentralized request-for-quote (RFQ) protocol, users’ assets are diversified into various liquidity providers through matching engines, simplifying subscriptions and redemptions. Beyond basic yield through RWAs, sUSD can be delegated to modular AVSs, enabling holders to participate in the security of decentralized systems while earning additional returns. A focus on transparency, on-chain verifiability, and rigorous security measures ensures that sUSD maintains stability, security, and a reliable peg. Through Solayer USD, the Solana ecosystem advances toward a decentralized, on-chain economy that expands stablecoin utility and liquidity.
