LP notifies the partner platform when a trade has been initiated. If it was a buy trade, the platform should return a wallet address of the asset. For example, if the user purchased 1 BTC, you return a BTC wallet address. If it was a sell trade, the exchange freezes the asset and wait for the trade execution result.交易发生时，LP通知交易所。如果用户买币，交易所需要返回用户拥有的该币种的钱包地址。例如用户买入1 BTC，交易所返回该用户的BTC钱包地址；如果用户卖币，交易所冻结用户的币，并等待交易结果，以决定下一步操作。
