On the layer2 orderbook dex of hpools, the seller can set their price for selling their hPool tokens. Notwithstanding the price set by the seller, which is at their own discretion, the platform will compute, at order placement time, the due success fee payable by the seller. This due success fee is a function of the fair cost of the hPool tokens at the time of order placement (i.e. the overall underlying value of the hPool portfolio divided by the number of hPool tokens, multiplied by the number of hPool tokens being sold), and the gains at that time (the difference between the overall underlying assets value at that time and at time zero of hPool launch).
