FIP-20: Add Stake DAO veFXS Gauge

Summary

Add a Stake DAO gauge to veFXS gauges.

Background & Motivation:

Our Stake DAO partnership has been quite successful and mutually beneficial. Our friends at Stake DAO have voted for FRAX with their veCRV and FRAX has successfully used Stake DAO’s custom FRAX strategy vault to increase the protocol’s AMO profits.

Recently Stake DAO expanded their retail FRAX strategy and we think it’s a great idea to boost adoption for this strategy with a gauge.

Expected gauge benefits: 1.) It essentially incentivizes more FRAX Curve liquidity since Stake DAO takes FRAX3CRV LP as deposits similar to Curve/Convex. 2.) Stake DAO is a whitelisted protocol that can stake veFXS so it will be in Stake DAO’s interest to build up the gauge weight for this in the future. 3.) Expand on our already successful partnership before which has gotten FRAX a lot of veCRV votes and Stake DAO $50m+ of TVL. 4.) Stake DAO can further incentivize this gauge with SDT rewards, doubling the token rewards for users.

For: Add Stake DAO veFXS Gauge
