The strongest evidence is Gate's official announcement page, "Gate TradFi : Trade Metals, Foreign Exchange, Indices, and More Global Markets," which explicitly says Gate TradFi offers access to gold, forex, global stock CFDs, major indices, commodities, and more under the same Gate account. This directly supports the claim about product categories. The statement that these products are available through Gate's App is also directly supported by the same announcement, which instructs users to update the Gate App and enter via the TradFi tab. Evidence for Web platform availability is weaker in the fetched material: the official announcement emphasizes app access and does not clearly state web access in the successfully fetched text. However, the search result for https://www.gate.com/tradfi describes TradFi as available across web and app, which supports the user's wording but was not directly fetch-validated in this run. Because the core product-category claim is directly supported by Gate's official announcement, but the App-and-Web wording is only partially validated, the overall claim is best assessed as likely true rather than fully confirmed with high confidence.
