### PR with Payload > > > \- enable GYD/aUSDC and GYD/aUSDT gauges on Arbitrum > \- vetted in rate providers …as used in other rehype pools > \- \[Proposal\](https://forum.balancer.fi/t/bip-642-enable-gyd-ausdc-and-gyd-ausdt-rehype-gauges-arbitrum/5830) ### Summary This is a proposal to enable two uncapped Balancer gauges for (1) GYD/aUSDC and (2) GYD/aUSDT Rehype Pools on Arbitrum. Since Gyroscope is managing these pools instead of the Balancer DAO we propose to start with a protocol fee of 50%, but further explore decreasing the protocol fee to 30%. The protocol fee shall kick in as soon as rewards start. With a lower protocol fee LP yield can be sustainably increased, helping to bootstrap the specified Rehype Pools. ### References/Useful links - [Documentation of Rehype Pools](https://docs.gyro.finance/gyroscope-protocol/concentrated-liquidity-pools/rehype-e-clps) - [Website](https://gyro.finance/) - [Github](https://github.com/gyrostable) - [Discord](https://discord.com/invite/2vnqnS7wE6) - [X](https://twitter.com/GyroStable) * * * ### Protocol description - stataArbUSDT (or in short, aUSDT) is the wrapped, static version of the rebasing Aave lending deposit token for aUSDT on Arbitrum. - [Aave](https://github.com/bgd-labs/static-a-token-v3) - stataArbUSDCn (or in short, aUSDC) is the wrapped, static version of the rebasing Aave lending deposit token for aUSDC on Arbitrum. - [Aave](https://github.com/bgd-labs/static-a-token-v3) - GYD is a USD denominated stablecoin, issued by the [Gyroscope protocol](https://gyro.finance/) * * * ### Motivation Gyroscope wants to obtain the option to participate in voting markets for two previously deployed pools. * * * ### Specifications #### Governance The Gyroscope Protocol will be governed by a DAO and relevant stakeholder with the full launch on Ethereum. For now, the FTL Labs multi-sig can pause the pool, change the swap fee and set the protocol fee. As a custom pool by Gyroscope, the E-CLP will be controlled by Gyroscope governance upon its launch. #### Oracles - aUSDC rate provider on Arbitrum: [0x87cD462A781c0ca843EAB131Bf368328848bB6fD](https://arbiscan.io/address/0x87cD462A781c0ca843EAB131Bf368328848bB6fD) - aUSDT rate provider on Arbitrum: [0x48942b49b5bb6f3e1d43c204a3f40a4c5f696ef6](https://arbiscan.io/address/0x48942b49b5bb6f3e1d43c204a3f40a4c5f696ef6) - GYD rate provider on Arbitrum: 0x00 #### Audits Audit reports by Nethermind, Trail of Bits, and Runtime Verification can be accessed here (the E-CLP is called the “CEMM” in these reports). In addition, the E-CLP code has been live in production on Polygon since November 2022. #### Centralization vectors No centralization vectors. The FTL Labs team’s multi-sig can - currently - pause the pool, change the swap fee and set the protocol fee. #### Market History - The Gyroscope Protocol is live on Ethereum since EOY23, with E-CLPs on several other chains.

The protocol fee shall kick in as soon as rewards start. With a lower protocol fee LP yield can be sustainably increased, helping to bootstrap the specified Rehype Pools. The Maxis will advise Gyro in how to best leverage the fee setting configuration as this has a direct impact on STIP and therefore ARB distributions based on how many fees are collected for a given epoch.
