[BIP-646] Enable Gauge for instETH/wstETH [Arbitrum]

PR With Payload https://github.com/BalancerMaxis/multisig-ops/pull/1109

Summary:

This is a proposal on behalf of InceptionLRT to enable a gauge for instETH/wstETH on Arbitrum. instETH is the Restaking Token dedicated to stETH, obtained through InceptionLRT’s restaking mechanism and platform. InceptionLRT is an omnichain liquid restaking protocol offering both Native and Isolated restaking to users. References/Useful links:

Protocol Description:

InceptionLRT is an omnichain liquid restaking protocol offering both Native and Isolated restaking to users. Powered by the Flash Unstake mechanism and supported by node operators with DVT Technology, InceptionLRT aims to become the most complete liquid restaking protocol in DeFi. The isolated architecture combined with the flash unstake feature solves the only drawback of isolated LRTs - liquidity fragmentation!

Motivation:

InceptionLRT aims to enable a gauge for instETH/wstETH to substantially increase the liquidity of instETH, while supporting its utility and viability for integration into a range of DeFi protocols.

Specifications:

1. Governance: ING holders participate in decision-making, influencing the protocol’s direction and policies, including the Node Operators, AVSs and restaking strategies. Incentive Allocation: Through gauge weight voting, veING holders direct incentives and rewards towards preferred liquidity, impacting the protocol’s dynamics. Rewards and Participation: Providing ING to liquidity pools like the 80-20 Balancer Liquidity Pools and locking the LP token earns veING, granting access to various protocol.

2. Oracles: Rate Provider for instETH.

3. Audits: InceptionLRT undergoes security audits and checks to ensure the safety of user funds. Latest: Audit Reports | InceptionLRT Docs.

4. Centralization vectors: The InceptionLRT Litepaper introduced the vision for Inception as a decentralized system where independent node operators work to power the growth and development of Web3. Further detailed information may be found here: EigenLayer - Inception iLRTs Docs.

5. Market History: 1. No major volatility - CoinGecko.

6. Value: The pool is intended to be the primary source of liquidity for instETH on Arbitrum and allow for a healthy stimulation of volume.
