abstract
This is a decentralized trading website, the exchange is set up to provide free trading for ‘SecondLive Token’, currently only supports’ SecondLive Bean/WBNB ‘trading pairs, all funds are held by users. There is no need for pre-charging, ‘Token’ transfers are done by contract (signature verification is performed on user-generated orders), and the exchange adopts a mixed mode to complete transactions:
- Complete order matching offline (find trade order pairs that match sell orders and buy orders)
- Online order settlement (check order information, complete order transaction settlement, fund transfer)
In this mode, users do not need to pay any ‘GAS’ fees when placing an order. A handling fee (1/1000) is charged after the online settlement. Therefore, users are free to place an order and cancel the operation without incurring transaction fees or ‘GAS’ fees as long as the order is not completed.

Also, if you are a Taker, you will be charged GAS charges, which are made through the WBNB transfer, ‘WBNB’ can convert ‘BNB’ to ‘WBNB’ through the ‘Wrap’ function, and of course it can convert ‘WBNB’ to ‘BNB’ using the ‘Unwrap’ function

Match Algorithm
The transaction adopts the price-time priority matching strategy, which is matched according to the price matching principle at first. If the prices are the same, match them in chronological order, for example, if a sell order of ‘10’ 0.001bnb and a sell order of ‘20’ 0.003bnb exists, and someone generates a buy order of ‘20’ 0.003bnb, Then ‘10’ will be sold at ‘0.001’ and ‘0.003’ respectively
