rsFIRO is the Rosen Bridge-wrapped representation of FIRO, a privacy-focused cryptocurrency built on the Lelantus Spark protocol. Each rsFIRO token is backed 1:1. Minted through Rosen Bridge's decentralized watcher and guard system rather than a centralized custodian. This allows FIRO holders to access liquidity, DeFi protocols, and trading pairs on other chains without relying on a centralized exchange. rsFIRO can be redeemed back to native FIRO at any time through the Rosen Bridge interface. Firo has been developing privacy-preserving protocols since 2016, including Zerocoin, Sigma, and Lelantus Spark, and rsFIRO extends that ecosystem's reach into cross-chain DeFi.
