> **Summary** > This is a proposal to enable a bb-a-USD gauge on Polygon. **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. **References/Useful links** > - [Website](https://app.aave.com/markets/) > - [Documentation](https://docs.aave.com/hub/) > - [Github Page](https://github.com/aave/interface) > - [Communities](https://governance.aave.com/) **Motivation** > This proposal aims to add a veBAL gauge for the Balancer Aave v3 Boosted Pool (bb-a-USD) on Polygon. > > Users will be able to migrate from the existing bb-a-USD pool built on Aave v2 to the new Aave v3 Boosted pool. The deposit yield on Aave v3 exceeds the deposit rate offered on Aave v2. > > There are wrappers for depositing funds into Aave Reserves, the linear pools, already deployed, utilise the wrapper developed by Aave Companies. This is the same wrapper used across all Aave linear pools. > > Balancer will be able to generate revenue from the yield generated by user’s funds being deposited into Aave v3. > > This pool uses the ComposableStablePoolFactory-v3 1 which addresses the [reentrancy vulnerability](https://forum.balancer.fi/t/reentrancy-vulnerability-scope-expanded/4345) disclosed during February 2023. This gauge is uncapped, and would enter as a “core pool” under [BIP-19](https://forum.balancer.fi/t/bip-19-incentivize-core-pools-l2-usage/3329). A portion fo the yield also allocated to bribes via Hidden hand there is a feedback loop which helps sustain the pool. **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](https://app.aave.com/governance/). > 2. **Oracles:** Aave uses Chainlink oracles for price feeds. > 3. **Audits:** You can find a record of audits of [Aave v3](https://github.com/aave/aave-v3-core/tree/master/audits). > 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. > > Pool Address: `0xb371aA09F5a110AB69b39A84B5469d29f9b22B76` > Gauge Address: `0x8D7d227746eE06D2532903D6EF1F69D80647C0E7` #### Transaction: _To allow time for emissions to move over and all LP’s to get the full benefit of AURA emissions this BIP will be executed in two parts. Part A will add the new bbaUSD [polygon] gauge and be executed immediately. Part B will kill the old bbamUSD gauge and be executed on May 2nd._ Part A: The DAO Multisig `0x10A19e7eE7d7F8a52822f6817de8ea18204F2e4f` will interact with the AuthorizerAdaptor at `0x8F42aDBbA1B16EaAE3BB5754915E0D06059aDd75` and call performAction with the GaugeController at `0xC128468b7Ce63eA702C1f104D55A2566b13D3ABD` for the target(address) argument and using 0x3a04f900 followed by the gauge address `0x8D7d227746eE06D2532903D6EF1F69D80647C0E7` and the corresponding gauge type for the data(bytes) argument. data(bytes) : `0x3a04f9000000000000000000000000008d7d227746ee06d2532903d6ef1f69d80647c0e70000000000000000000000000000000000000000000000000000000000000003` ### Killing Old Gauge Part B: The DAO Multisig `0x10A19e7eE7d7F8a52822f6817de8ea18204F2e4f` will interact with the AuthorizerAdaptor at `0x8F42aDBbA1B16EaAE3BB5754915E0D06059aDd75` and call performAction using `0xab8f0945` for the `data(bytes)` argument and `0xbbCd2045ac43F79E8494600e72cA8AF455E309Dd` for the `target(address)` argument. `0xbbCd2045ac43F79E8494600e72cA8AF455E309Dd` is the polygon root gauge address for bbamUSD **Disclosure** > This proposal is the sole work of @Llama contributor, @Matthew_Graham, via the legal entity TokenLogic. Llama is a Service Provider to Aave DAO. ---

note for balancer maxis, let’s include the killing of existing bbamUSD gauge in this proposal ---
