[GIP-66] CA side incentives reduction

This is in reference to GIP-22, which started the LM program last year. Part of the LM program focussed on incentivising Credit Account users with GEAR rewards. It was done for the sake of early user appreciation and GEAR distribution, not as a financial incentive as it was too small even on day 0. At this point, these numbers are small and don’t present any benefit.

Another reasoning is that with the arrival of Curve V2 pools and then V3 - leverage opportunities will become multiplied. Meaning that Credit Accounts in V3 will have more farms, trading options, and better avenues for making higher yields! Organic traction should be expected there, whereas any small incentives would not help the product while might distort outside interpretation of traction. Moreover, with V3 changing the architecture, doing such rewards in a semi-manual day would have been very cumbersome. Overall, all reasons point to cutting it.

No other rewards are currently being cut. Both passive lender side and GEAR/ETH are live.

Thus, it makes sense to optimize our token spends and remove Credit Account token spends. As the protocol improves and goes into V3 and on Layer 2 rollups, it would be ideal to see GEAR emissions to almost fully be cut. However, it’s not the time for it yet given the early stage of Gearbox and industry yields. Once the situation changes, turning emissions into burning / redistribution is the desired outcome. And efforts are being done to achieve that.

This will save 0.196% of the supply on an annual basis, equal to $100K yearly.
