The assessment is primarily based on Source 1, an official Fidelity webpage with maximum authority and relevance. This source provides a direct announcement stating that Solana (SOL) has been added to the Fidelity Crypto® platform, making it available for clients to buy, sell, and transfer. This is the strongest possible evidence and directly confirms the statement.There is conflicting evidence from Source 3, another official Fidelity page, which only lists Bitcoin and Ethereum as available for trading. However, this is evidence by omission. It is highly probable that this more general trading page has not been updated to reflect the specific, more recent announcement of Solana's addition. A direct, affirmative announcement (Source 1) is more dispositive and carries more weight than the absence of information on a potentially outdated general page (Source 3).Other sources discussing Fidelity's intent to offer a Solana ETF (Sources 4 and 6) are about a different financial product but show the company's interest in Solana, which makes the direct offering plausible. The remaining sources have low relevance as they discuss institutional services, are purely educational, or are from low-authority platforms.In conclusion, the direct confirmation from a primary source announcement (Source 1) strongly outweighs the contradictory evidence by omission, making the statement very likely to be true.
