Is dYdX on Solana?

Could you please clarify for me if the platform dYdX is indeed operating on the Solana blockchain? I've been hearing mixed opinions about this, and I'm eager to get a definitive answer. If it is indeed on Solana, could you also elaborate on the benefits or advantages that this partnership or integration might bring to both parties? On the other hand, if dYdX is not on Solana, could you explain the reasons behind this decision? Thank you for your time and assistance in clarifying this matter.
