The evidence overwhelmingly and consistently supports the statement. The provided sources, all of which are highly authoritative and originate from Coinbase's own platform, offer direct proof. The Coinbase Exchange Status page provides definitive technical evidence by listing a specific contract address for the JUPITER asset on the 'Solana network (SPL token),' confirming its integration at the core exchange level. Furthermore, the existence of a Coinbase converter tool for the CAPY token, which is explicitly identified as a Solana SPL token, demonstrates functional support for transactions, a form of trading. This is corroborated by multiple other official Coinbase asset pages for tokens like ACS, ORCA, and PSY, all of which are clearly identified as being built on the Solana blockchain. The summary of another source indicates Coinbase is involved in DEX trading for Solana tokens, further reinforcing the conclusion. There are no contradictions in the evidence provided. The cumulative weight of these primary sources confirms that the Coinbase platform lists, tracks, and provides trading/swapping functionality for tokens based on the Solana blockchain.
