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 is the highest authority for this type of information. This source explicitly states that Doodles (DOOD) and Moonbirds have been added to the asset listing roadmap, directly confirming the statement.This primary evidence is further corroborated by multiple secondary sources, including a news article from the cryptocurrency exchange Phemex (in both English and Korean) and posts from news aggregator accounts. All sources are in complete agreement, and there is no conflicting evidence presented. The combination of a direct, authoritative primary source and consistent secondary reporting provides high confidence in the truthfulness of the statement.
