UAEがデジタル・ディルハムを使用した初の全国規模取引を実施

The evidence strongly and consistently supports the statement. The most authoritative source is a primary one from the official social media account of the UAE Ministry of Finance, which explicitly announces a 'new national milestone' and the 'first transaction event' involving the Digital Dirham. This official government confirmation is directly corroborated by multiple secondary sources, including reputable crypto news outlets like Cointelegraph and PANews, which also report that the first transaction has been successfully completed. One source specifically uses the phrase 'first nationwide transaction,' directly matching the claim. There are no contradictions among the relevant sources provided. The only irrelevant source, a press release from Visa about a different pilot, does not detract from the weight of the consistent and authoritative evidence supporting the claim.
