### PR with Payload
[https://github.com/BalancerMaxis/multisig-ops/pull/547](https://github.com/BalancerMaxis/multisig-ops/pull/547)
**Summary:**
> This pool uses the composable stable pool factory v5 and contains three unique staked ethereum tokens, staked frax eth (sfrxETH), wrapped staked eth from Lido (wstETH), and rocket eth from Rocket pool (rETH). As most Balancer community members know, rocket pool and lido have become pillars of the ecosystem through the use of the metastable / composable stable pool types to leverage their yield bearing assets. Staked frax eth will be joining these two juggernauts to facilitate trading and LPing amongst these diverse staking strategies of ETH. This gauge would enter as a “core pool” under BIP-19, meaning protocol fees earned by this pool would be used to bribe for votes on it.

**Protocol Description:**
> sfrxETH is a Frax’s staked wrapped ETH token, wstETH is a wrapped staked ETH token for Lido, and rETH is the staked ETH token for Rocket Pool.
**Motivation:**
> Balancer is clearly pushing forward on all networks with staked assets as a key focus. By diversifying the protocols which supply staked assets Balancer opens up the door to liquidity providers to gain exposure to multiple providers, while facilitating trade routes for these assets. The protocol benefits greatly from yield bearing assets, and Balancer’s users do just as much. This pool will be a unique and diverse group of Ethereum assets making it exciting for everyone involved.

2. **Oracles:** See each rate provider contract linked here respectively [sfrxETH](https://optimistic.etherscan.io/address/0xf752dd899F87a91370C1C8ac1488Aef6be687505), [wstETH](https://optimistic.etherscan.io/address/0x9aa3cd420f830E049e2b223D0b07D8c809C94d15), [rETH](https://optimistic.etherscan.io/address/0x658843BB859B7b85cEAb5cF77167e3F0a78dFE7f)
3. **Audits:** See [sfrxETH](https://docs.frax.finance/other/audits), [wstETH](https://github.com/lidofinance/audits), [rETH](https://medium.com/rocket-pool/rocket-pool-staking-protocol-part-4-2635c44e4f7e).
4. **Centralization vectors:** Rocket Pool is a [protocol for decentralized and trustless ETH2 staking](https://medium.com/rocket-pool/rocket-pool-staking-protocol-part-1-8be4859e5fbd). For Lido and wstETH please read [here](https://lido.fi/faq). Lastly for FRX and sfrxETH see [here](https://docs.frax.finance/frax-ether/overview).
5. **Market History:** See [rETH](https://www.coingecko.com/en/coins/rocket-pool-eth), [wstETH](https://www.coingecko.com/en/coins/wrapped-steth), and [sfrxETH](https://docs.frax.finance/frax-ether/frxeth-and-sfrxeth)
6. **Value:** Balancer will earn the protocol fee on all assets in the pool and so will LPs. The BIP-19 flywheel will incentivize TVL to grow here with trading volume and our staked ethereum pillars will continue to have Balancer as their ideal liquidity destination.
