[FIP - 235] Add crvUSD/Frax pool to the FXS gauge controller

Author

C2tP (Convex Finance)

Proposal

Create a FXS gauge for a Convex crvUSD/Frax LP position. https://curve.fi/#/ethereum/pools/factory-crvusd-4

The staking token is a wrapped Convex staking position represented by an erc-20 that receives CRV and CVX rewards. This token can then be staked on a Frax Finance gauge to then also receive FXS rewards.

The wrapped staking position itself is an unmanaged trustless position and can be found on the Convex github at https://github.com/convex-eth/platform/blob/main/contracts/contracts/wrappers/ConvexStakingWrapperFrax.sol

Note that a previous FIP(110) passed for the addition of a crvUSD/FraxBP FXS gauge. The team decided a direct crvUSD pairing would be better suited for this particular pool.

Voting

• For: Add the crvUSD/Frax pool to the FXS gauge controller as a staked Convex position.

• Against: Do nothing.
