[ARFC] Add Contango Protocol, Cian Protocol and Index Coop to flashBorrowers on Aave V3

[IrrationalExuberance]

@ACI

Currently, every flashloan has a 9 bps fee that rewards liquidity providers in Aave. While flashloans were created by Aave, the ecosystem as a whole has replicated this feature, and most protocols do not implement any fees.

The ACI does not support waiving the fees for flashloans in general, as we firmly believe that users’ funds used, even in the context of a single transaction, should be rewarded.

However, some strategic use cases of V3, such as emode, are very fee-sensitive as they mobilize high leverage. Waiving the Contango Protocol and Cian Protocol flashloan fees is expected to make these strategies more convenient and profitable, leading to increased borrow volume and thus increased Aave DAO revenue.

Agreed on the rationale. I dont know Contango, but I use CIAN and I have always liked it and considered it very value accretive to AAVE.
