FIP - 67 - Kill mStable FRAX/mUSD pool staking rewards and remove from gauge

Summary:

Remove FRAX/mUSD gauge so the pool stops receiving FXS.

As pointed out by community members, FRAX/mUSD liquidity pool is relatively small in terms of TVL and participation in 24h volume of FRAX transactions. Especially with the recent market concerns with stable coins, users not comfortable holding mUSD (fine with holding frax though)

We would like to propose removing the gauge from FXS as this essentially allows stable pools and other FRAX/FXS/FPI/FPIS-focused pools to gain more rewards. Also, FXS emission would be used more efficiently for the stability of FRAX as well as the extension of the market cap of that.

This is somewhat of an unusual proposal and it will also be used as a way to test community sentiment on having FXS receiving gauges on pools that source their yield from FXS.

Implementation:

We will set the farm reward to 0 for FRAX/mUSD pool and people can withdraw from the farm afterward.

• Kill FRAX/mUSD gauge
