The statement is strongly supported by an overwhelming number of high-authority, high-relevance primary sources. The official Solana website (solana.com) features dedicated pages for a protocol named 'x402' in multiple languages, including Portuguese, French, Vietnamese, Greek, and Ukrainian. These pages uniformly describe x402 as an internet-native payment protocol on Solana, specifically designed for AI agents and digital transactions. This is the most direct and credible evidence possible.Further corroboration comes from a post by the Head of Strategy at the Solana Foundation, Austin Federa, who explicitly confirmed the existence of 'x402 on Solana' in the context of financial payments. Additionally, secondary sources from major crypto data aggregator CoinGecko and news outlet Bitget report that Solana announced or launched an initiative and an affiliated Twitter account named 'x402 on Solana'.While a couple of sources contain confusing or potentially mismatched information, suggesting x402 might be a broader standard or linked to other entities, they have lower relevance scores and do not directly contradict the core claim. The possibility that x402 is an open standard that Solana has implemented and branded as its own product does not invalidate the statement that Solana 'launched a product or protocol' with that name. The collective weight of the primary evidence from Solana itself makes the statement highly credible.
