You Kaidex exchange is supporting only tokens based on KardiaChain? Why do not you add other blockchain wrapped tokens?
Do you have own launchpad? As far as I understood this tokens which listed on your Dex had IDO on your platform?
Kardiachain has a bridge for Ethereum and BSC. It support USDT,ETH,BNB and BUSD pairs via
https://kaidex.io/bridge . And Kardiachain has own launchpad called
https://kaistarter.kardiachain.io/ .
Kardiachain is fast and cheap transaction fee compared to other blockchain. You should try it.
