Motivation
For a refresher on what the Batch Relayer is you can review the proposal to approve the Batch Relayer and to approve the Batch Relayer v2. The functionality added in v3 is primarily to aid in the coming migration of stabal3 and bb-a-USD to the soon to be deployed new version of bb-a-USD. This new bb-a-USD addresses the vulnerabilities previously disclosed here and also includes new features like recovery mode and the ability to apply Balancer’s protocol fee to the Aave yield.
Additionally, the new Batch Relayer will have the ability to stake & unstake in the gauges on behalf of the user. This will allow the above mentioned migration to be completed in a single transaction (after the user has approved the Batch Relayer). It can also claim incentives from gauges on behalf of the user, opening the possibility for single-transaction claim-invest-stake flows.
