[BIP-158] Migrate wstETH/WETH Gauge [Arbitrum]

Summary:

This pool uses the metastable pool factory and contains Lido's liquid staking derivative of ethereum, wstETH. The reason for this pool deployment is to replace the composable stable pool implementation of this pairing with a pool which Balancer can continue to collect the fees on properly. Due to the activation of recovery mode, the current pool is being streamed BAL incentives without the DAO being properly compensated for the fees the pool generates. This proposal will effectively activate this new pool’s gauge and kill the current pool’s gauge to foster migration of liquidity to the preferred pool.

Protocol Description:

wstETH is Lido’s wrapped staking derivative as featured in many other Balancer pools. WETH is wrapped ETH.

Motivation:

Described in the summary, the protocol can collect fees on the metastable pool and not the composable stable pool. Moving the incentives will motivate the liquidity providers to migrate their liquidity to the better pool option for Balancer.

Specifications:

Governance: wstETH. Oracles: See each rate provider contract linked here wstETH , Audits: See wstETH. Centralization vectors: For Lido and wstETH please read here . Market History: See wstETH Value: Balancer will earn the protocol fee on all assets in the pool and so will LPs. The BIP-19 flywheel will incentivize TVL to grow here with trading volume and our staked ethereum pillars will continue to have Balancer as their ideal liquidity destination.
