The statement is strongly supported by high-authority primary sources. The official press release from Western Union's investor relations website is the most definitive piece of evidence, directly announcing the company's plan to launch a stablecoin on the Solana blockchain. This is corroborated by a social media post from Solana's official account, confirming the partnership from their end. Furthermore, a news article directly quotes CEO Devin McGranahan's statement confirming the use of 'Solana's blockchain technology,' which directly supports the claim that the CEO confirmed the selection. One source mentions the CEO was exploring several options, including Solana, without confirming a final selection; however, this information is likely outdated or less specific compared to the official company press release which represents a final decision. The remaining sources are irrelevant to the claim. The combined weight of the official company announcement, the partner's confirmation, and a direct quote from the CEO makes the statement highly credible.
