The evidence strongly and consistently supports the statement. The most direct piece of evidence is the official Coinbase DEX page, which explicitly states that users can 'Trade millions of Solana and Base tokens... in the Coinbase app.' This is a direct confirmation from a highly authoritative primary source. Further reinforcing this, the official Coinbase website hosts dedicated price and information pages for Solana (SOL), including a UK-specific version, which is standard practice for assets available for tracking, buying, and selling on the platform. Additionally, official developer documentation confirms that Coinbase offers staking services for Solana to its institutional clients via Coinbase Prime and has integrated Solana support into its developer tools. All sources are primary, authoritative (from Coinbase itself), and corroborate each other without any contradiction, collectively proving that Coinbase provides its users—spanning retail, institutional, and developers—with multiple forms of access to Solana assets directly through its services and app.
