We appreciate your concerns about our DEX implementation. Vite DEX adopts maker-taker model for order matching. Loopring is not implemented at this time cause considering at the beginning phrase of DEX there won’t be a large number of orders and pairs. And Loopring only shows its advantages when many orders are waiting to be matched in different pairs. When Vite MainNet launches, we still may consider to bring Loopring on-board once situation fits.
