@DonBera - Fees

PR - #440

[DonBera]

can't comment on the link.

BTW I would add reference that fee starts from 0.01% not 0.3% (0.3% is min for weighted but stable have lower fees).
Last but not least I think that fee for BGT staker is 50% the value of fee chosen in the pool not a fix 0.1%.

Thanks!

These are the fees limit which are defined on smart contract level (same for both type of pools)
uint256 private constant _MIN_SWAP_FEE_PERCENTAGE = 1e12; // 0.0001%
uint256 private constant _MAX_SWAP_FEE_PERCENTAGE = 1e17; // 10%
@DonBera i think abv limit you mentioned are controlled on the UI so if the purpose of the doc is to help kinda educate on the UI side, looks fine to me

[sj448]

also not always 50% of swap fees moves to BGT stakers, we have the functionality to route some fee out of that 50% to feeReceiver (think of it as treasury addr) that being said initially whole 50% will move to polFeeCollector, see if we wanna add this

yes, I was referring to UI related action and financial meaning.
A stable pool being super efficient can allow very small Fees while Weighted pool better to have at least 0.3% fee.

On fee split worth mentioning 50% stays to LP and 50% goes to PoL ( or to BGT stakers or to foundation)? I think it can also remain an internal detail @blackbera what do you think?

[blackbera]

waiting for one last pass through with @sj448 on this

Do we want to add below detail?
Fee split is 50/50 between LPs and protocol.
Fees collected by protocol{inside ProtocolFeesCollector} is then split between BGT staker and treasury, ratio of which is configurable {polFeeCollectorPercentage inside ProtocolFeesWithdrawer contract} but most of the portion will go to BGT staker.

[sj448]

should replace BGT staker in this image with protocol, as in later section protocol fee split is explained.

rest all technically looks good, @DonBera please check from ur end too

fixed moving to ready
