The reason why BNBX/BNB TVL is only 2915$ is likely due to the issues with Ankr. As people have likely withdrawn from their wallets and the price has dropped, this has had an effect on the overall TVL. Additionally, Ellipsis has currently been experiencing API issues, which could also be contributing to the low TVL. Therefore, the combination of the Ankr issue and the Ellipsis API issue has caused the BNBX/BNB TVL to be only 2915$.
