マスターカード、リップル、ジェミナイがXRPL上でカード決済のテストを実施

The assessment is based on exceptionally strong and consistent evidence. The primary source, a press release from Ripple, explicitly and authoritatively confirms the partnership with Mastercard and Gemini. It directly states that the collaboration is for a pilot program to test the settlement of fiat card transactions on the XRP Ledger using Ripple's stablecoin, RLUSD. This single source validates every component of the statement.This official announcement is further corroborated by multiple high-authority news outlets, including Yahoo Finance, which reported the partnership and its purpose as a factual event. Another involved party, Gemini, confirms its support for the RLUSD stablecoin on the XRP Ledger, which is the specific asset and technology mentioned in the settlement test. Although this source does not mention Mastercard directly, it validates a critical piece of the initiative. The remaining sources, while having lower authority, are all consistent with this news, and no contradictory evidence was provided. The cumulative weight of a direct primary announcement supported by credible, independent reporting makes the statement highly likely to be true.
