### Summary

This is a proposal to enable one uncapped Balancer gauge on Arbitrum for an aGHO/USDe E-CLP.

### Protocol description

- aGHO is the deposit receipt token issued by the Aave protocol to lenders of GHO. Since aTokens are rebasing, this pool uses BGD Labs’s statA wrapper that is a repricing representation of statA tokens that reflects the accruing lending yield. GHO is issued by [Aave](https://app.aave.com/).
- USDe is a “delta-neutral synthetic dollar” issued by [Ethena](https://ethena.fi/).

### Motivation

Gyroscope is launching further strategic 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

- ‘rateProvider0’ for aGHO: [0x177862A0242acD8b5F9cc757a963c1C8883da45E](https://arbiscan.io/address/0x177862A0242acD8b5F9cc757a963c1C8883da45E) and relevant [review](https://github.com/balancer/code-review/blob/main/rate-providers/statATokenLMRateProvider.md).
- ‘rateProvider1’ for USDe: 0x0000000000000000000000000000000000000000

#### 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 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. Details available [here](https://dune.com/gyro_finance/gyroscope-e-clps).
- This is the first aGHO/ USDe E-CLP.

## Value

As per “Motivation”.

- Arbitrum root gauge on Ethereum: [0xD558C611B69a223767788B638717E868D8947Fd0](https://etherscan.io/address/0xD558C611B69a223767788B638717E868D8947Fd0)

Specification

Transaction: The Balancer Maxi LM Multisig `eth:0xc38c5f97B34E175FFd35407fc91a937300E33860` will interact with the gaugeAdderv4 at `0x5DbAd78818D4c8958EfF2d5b95b28385A22113Cd `and call the `addGauge` function with the following arguments:

- gauge(address): `0xD558C611B69a223767788B638717E868D8947Fd0`
- gaugeType(string): `Arbitrum`
