The evidence strongly and directly supports the statement. The most compelling proof comes from high-authority primary sources on Coinbase's own website. The price pages for CATO, Jupiter (JUP), and Ondo US Dollar Yield (USDY) all feature a prominent "Trade on Coinbase Wallet" button. These pages explicitly identify the assets as being on the Solana network; for instance, CATO is described as a "meme token on Solana," and the USDY page lists a specific Solana contract address. Crucially, these tokens are not listed for trading on the main Coinbase centralized exchange, confirming that the functionality is for unlisted assets. The CATO page even mentions a "serum dex," directly linking the trading mechanism to a decentralized exchange on Solana. This evidence is corroborated by a news article about Coinbase acquiring Vector.fun, a Solana-based trading platform, which indicates a clear strategic move to integrate Solana DEX capabilities. While some sources were irrelevant, none of the provided evidence contradicts the statement. The combination of direct functional evidence from the primary platform and supporting strategic news provides high confidence that the statement is true.
