Balancer

PR with Payload

Summary:

This proposal is to create a gauge for ETHx / bb-a-wETH on Ethereum.

The pool shall use the ComposableStablePoolFactory-v4 which addresses the reentrancy vulnerability disclosed during February 2023.

This gauge is uncapped, and would enter as a “core pool” under BIP-19. This means 65% of 50% of yield generated by this pool is to be used for bribing for votes on it via Hidden Hand. The remaining 35% goes to Balancer DAO as revenue.

Protocol Description:

This pool utilises ETHx and linear pool bb-a-wETH which deposits wETH into Aave v3 wETH reserve. The linear pool utilises a wrapper developed by Aave Companies.

Motivation:

This proposal aims to add a veBAL gauge for ETHx/bb-a-wETH on Ethereum.

One of Balancer’s strategic objectives is to attract more yield bearing liquidity. Incentivizing the yield bearing token ETHx through a gauge proposal presents an opportunity to attract depsits into the liquidity pool.

The primary pool for ETHx is to be on the Balancer Protocol. This further deepens the existing relationship with MaticX/bb-a-wMATIC and SD/wETH already deployed on Polygon and Ethereum respectively.

Launching ETHx with the bb-a-wETH linear pool will provide additional yield for Liquidity Providers. This is due to the Aave v3 wETH reserve generation 178 bps of deposit yield. Balancer DAO will earn revenue from ETHx and bb-a-wETH derived yield.

4. Centralization vectors:

• Stader Governance, see here

5. Market History:

• ETHx is new and not yet integrated into Coingecko.
• bb-a-wETH has a long successful history within Balancer protocol.

6. Value:

• This pool is a Core Pool and therefore will generate revenue for the DAO via ETHx and bb-a-wETH derived yield plus swap fees.
