Performance Fee: 10%
The performance fee is charged by Typus to the Option Seller (who is also the Vault Depositor), because the option seller is the net premium (reward) receiver. It is only charged when an option seller makes profit from the vault.
Withdrawal Fee: 0.0%
Claim Fee: 0.1%
The claim fee is charged by Typus to the Option Seller (who is also the Vault Depositor).
0.1% of the claim fee is only charged after a vault is activated (auctioned). Users are able to withdraw anytime with a 0% withdrawal fee before vault activation (auction).
Trading Fee: min (0.3% of underlying value, 10% of options price)
The trading fee is charged by Typus to the Option Buyer (who is also the Vault Bidder).
Trading fees can never be higher than 10% of the options price. For example, if a SUI option is traded at the price of 0.0001 SUI, the trading fee will be 10% of 0.0001 SUI = 0.00001 SUI (as opposed to 0.3% * 1 SUI = 0.003 SUI). Hence, the fee is a minimum number of 0.3% of the options underlying value and 10% of the options price (premium).
