Thank you for your question.
That's right. When it comes to executing FBA orders, there are two possible approaches: the pro-rata method and prioritizing orders that arrive earlier within the batch period. For the sake of simplicity in this PoC, we implemented the latter approach.

Got it. Thanks for the comment
Also, just curious, why do these lines return encoded function data and emit an event on callback? Is that implemented incompletely for upcoming feature?
Hi, Titania Research Labs team. I'm new to this field. So, please kindly correct me if I'm wrong. I'm wondering what I found is a bug or not.
Description
According to this link, amount is filled on a pro rata basis. It's not like CLOB. Or originally is this orderbook-style DEX?

In the following test, two sell orders should fill 50 amount each but actually they fill 90 and 10 amount in order.
