Freq Set Dollar (Frequ Set Dollar, FSD) is a decentralized ERC20 USD stablecoin featuring censorship resistance and no collateral requirements. Inspired by Empty Set Dollar (ESD) and Dynamic Set Dollar (DSD), FSD shares similar mechanisms but differentiates itself primarily in frequency. By increasing the epoch frequency, shortening DAO and LP lock-up periods, and providing more aggressive incentives for liquidity providers, FSD responds more quickly to market demand.
