The Palau Stablecoin (PSC), a government-issued digital dollar from the Republic of Palau.
The engine treats it as a first-of-its-kind sovereign pilot on Ripple's central-bank-currency platform.
Its dollar-backed stablecoin runs on Ripple's CBDC Platform, using the XRP Ledger. Phase One began in 2023 with government employees making retail purchases at select merchants.
It's notable as the first national government to build such a currency pilot on XRP Ledger infrastructure — an early real-world test of state-issued digital money.
