The assessment is based on exceptionally strong and consistent evidence. The primary source is a direct announcement from the official Coinbase Markets X (Twitter) account, which holds the highest possible authority and relevance, explicitly stating that MegaETH (MEGA) was added to its listing roadmap. This definitive statement is corroborated by a multitude of secondary sources, including reputable crypto data and news platforms like Cryptorank and CoinNess, all of which independently report the same information. There is a complete absence of contradictory evidence within the provided materials. While some sources were irrelevant or offered weak support, they did not challenge the core claim. The convergence of a direct, official announcement with widespread confirmation from multiple secondary sources provides a high degree of confidence in the statement's truthfulness.
