Introduction #

Transaction History #

• Each OrderHistory event is triggered by the execution of a DODOProxy contract. If the transaction is routed to a trading pool on DODO, the events triggered by the underlying pool will be ignored to prevent duplicate logging.
• If the transaction does not come from DODOProxy, then the transaction events triggered by the underlying pool will be logged by OrderHistory.

Trading#

• Every transaction event comes from a smart contract on the DODO platform.

Trading Pool Information #

• Real-time pool status tracking by trading pair
• Note that VIRTUAL type pools are pools that do not actually exist, and are created for statistical purposes only
