The XRP Ledger (XRPL) and the Bank for International Settlements’ (BIS) Project Meridian share a common ambition: enabling cross-system value exchange with either complete success or failure. This atomic settlement model mirrors the approach taken by XRPL, which has been proven to work in real-world settings. 2025’s Project Meridian FX successfully demonstrated this concept using PvP settlement across various payment infrastructures. The goal was to permit simultaneous exchange of central bank money (via RTGS systems) and other assets on different ledgers. For example, cross-currency payments on XRPL are atomic: either the entire payment is completed or nothing happens at all, ensuring a guaranteed finality in each transaction.
