What is Juice Dollar (JUSD) Stablecoin from Citrea Ecosystem?

Juice Dollar (JUSD) is one of the more unconventional stablecoins to emerge recently — a Bitcoin-collateralized, oracle-free stablecoin built natively on Citrea's Layer-2 ecosystem. Unlike USDT or USDC, which lean heavily on centralized issuers and bank reserves, JUSD operates entirely on-chain without relying on external price feeds, making it structurally different from most USD-pegged tokens in the market today.
