The statement is strongly supported by multiple independent news sources (ainvest.com, cryptowisser.com, financefeeds.com, bitcoinnews.ch) and is directly confirmed by one of the named partners, DFX.swiss, on its official X account. The evidence also includes a quote from the Managing Director of SPAR Switzerland acknowledging the partnership. While there is a discrepancy across sources regarding the number of participating stores (some state 100, others 300), the core claim of a partnership between Spar, Binance Pay, and DFX.swiss is well-corroborated.
