Curve Pool Address: 0x383e6b4437b59fff47b619cba855ca29342a8559
Curve Pool Gauge: 0x9da75997624c697444958aded6790bfca96af19a

This proposal aims to add receivers for the PayPool/mkUSD metapool on both Curve and Convex. It will allow vePRISMA voters to direct PRISMA emissions to the pool once it is passes as a gauge and further grow TVL and liquidity for mkUSD. To drive this process, Trident will incentivize the PayPool/mkUSD metapool.

A PayPool basepool was recently created and we are in the process of creating the mkUSD metapool to pair with the basepool. Trident plans to direct voting incentives towards the pool to deepen liquidity for both assets. A gauge for PRISMA emissions will further deepen liquidity and grow mkUSD and pyUSD within the Curve ecosystem.
