Juice Dollar (JUSD)

Juice Dollar is a decentralized protocol that issues JUSD, an overcollateralized, oracle-free, and censorship-resistant stablecoin built on Citrea, a Bitcoin Layer 2. JUSD is pegged to the USD. The system allows users to mint JUSD by depositing approved collateral, with all issuance and repayment occurring fully on-chain without reliance on price oracles or admin controls. The protocol includes native functionality for saving and borrowing, enabling users to earn yield on JUSD through an integrated savings module and protocol pools that generate additional fee-based returns. JUSD supply is dynamically adjusted based on user activity, expanding and contracting as positions are opened and closed. By removing external dependencies and central control points, Juice Dollar provides a self-contained and permissionless stablecoin system within the Citrea ecosystem.
