[BIP-239] Enable bb-a-USD gauge [Ethereum]

PR with Payload

Summary

This is a proposal to enable a bb-a-USD gauge on Ethereum.

Protocol Description

The Aave Protocol is a decentralized liquidity protocol that is deployed across many EVM compatible networks including but not limited to Optimism, Arbitrum, Avalanche and Polygon.

Currently, the Aave Protocol has a TVL of approximately $5 Billion.

Motivation

This proposal aims to add a veBAL gauge for bb-a-USD.

Bb-a-USD was the flagship boosted pool for Balancer. However, whilst Balancer recently launched new pools on Aave V3 to ensure continued payment of protocol fees, the bb-a-USD pool wasn’t migrated and was later wound down as it was built on Aave V2. Initially, there was no migration support for Aave V3, which has been deployed on Ethereum since 27/01/23.

Now that USDT is listed on Aave V3, as shown by this proposal, it is possible to add the bb-aUSD gauge through this proposal.

Specifications

1. Governance: AAVE and stkAAVE serve as the governance tokens for the Aave DAO. Holders can vote on proposals at both a Snapshot level and through the Aave DAO on-chain governance portal.

2. Oracles: Aave uses Chainlink oracles for price feeds.

3. Audits: You can find a record of audits of Aave V3 here.

4. Centralization Vectors: Aave Governance is decentralized, and all changes must go through a transparent and well-tested governance process.

5. Market History: There is a long history of bb-a-USD as a successful boosted pool within Balancers protocol.
