FIP 3 - Change the fee rate for Create mode

Summary

Adjust built-in fee parameter set to 0.2% (Furucombo Create only)

Abstract

It has been over 2 years since we first introduced the concept of Furucombo. Since then, 4000 different trading strategies were inspired with the drag-and-drop DeFi cubes under create mode. While it is currently free of charge (since its inception), our community is convinced by the value it creates. It is an important step to let it generate revenue to support the governance and further development of Furucombo.

Currently there is a built-in fee parameter set to be 0 which can be modified. The fee parameter can be adjusted to charge a certain percentage of initial funds from the users performing transactions with the create mode. We seek the community signal for the change of this fee parameter. The fees collected would go to Furucombo Treasury, and could be further converted into tokens like COMBO/USDC LP tokens.

Proposal

Set the fee rate at 0.2%.

Fee Calculation Example:

Swap 1ETH to DAI, then fee = 1*0.2% ETH.
Swap 1ETH to 1500 DAI + swap 500 DAI to COMBO + swap 500 DAI to AAVE + swap 500 DAI to LINK (4-cube combo), then fee = 1*0.2% ETH still.

Rationale:

The fee rate is derived from the fee for users who do asset management elsewhere. Basically the more complex a transaction, the more cost effective to use Furucombo’s create mode. There would be no fees currently for doing flash loans, as it will not be counted as initial funds. On the other hand, some Furucombo use cases are not super complex but are unique and exclusive. For example, users can customize the swapping route to get a better rate in certain trading pairs (normally Curve related pairs).
