The claim is directly supported by the official Coinbase Markets source, x post 2046696391880155400, which states: perpetual futures trading for Gold and Silver will go live on 22 APR 2026, and the GOLD-PERP and SILVER-PERP markets will begin if liquidity conditions are met in supported regions. That wording matches the claim closely. The other fetched links, Coinbase将上线Diem(DIEM)现货 and BitMart 合约将上线 NATUSDT, are unrelated and neither support nor refute the statement. No conflicting evidence was found among validated sources.
