[BIP-364] Enable TruMATIC / bb-a-wMATIC Gauge [Polygon]

PR with Payload: https://github.com/BalancerMaxis/multisig-ops/pull/373

Summary:

This proposal is to create a gauge for truMATIC/bb-a-wMATIC on Polygon.

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:

TruFin builds institutional-grade DeFi primitives, that can be used as the foundational building blocks for complex digital asset strategies to reduce risk, generate rewards, securely on-chain. TruStake is a MATIC staking vault which provides access to MATIC staking on the Ethereum network.

TruMATIC is the liquid staking token users receive when they deposit MATIC into the TruStake vault. It is an ERC-20 token like MATIC and has all the same basic functionality. As soon as you deposit MATIC on the TruStake smart contract, you receive newly minted TruMATIC, based on the exchange rate at the time of staking. As MATIC staking rewards accrue, the value of TruMATIC increases (with reference to MATIC).

Motivation:

This proposal aims to add a veBAL gauge for truMATIC/bb-a-wMATIC on Polygon.

One of Balancer’s strategic objectives is to attract more yield bearing liquidity. Incentivizing the yield bearing token TruMATIC through a gauge proposal presents an opportunity to deepen Balancer liquidity. Balance is to become the main liquidity destination for TruMATIC. Launching a bb-a-wMATIC pool will provide additional yield for Liquidity Providers (LPs) after fees and bribes, relative to other pool types. This is due to the Aave v3 wMATIC reserve generation 218 bps of deposit yield.

2. Oracles:

• rateProvider0 (for truMATIC):0x4b697C8c3220FcBdd02DFFa46db5a896ae7a0843`
• rateProvider1 (for bb-a-wMATIC): 0xE4885Ed2818Cc9E840A25f94F9b2A28169D1AEA7

3. Audits:

5. Market History:

• truMATIC is new and not yet integrated into Coingecko.
• bb-a-wMATIC has a long successful history within Balancers protocol.

6. Value:

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