[PR with multisig payload](https://github.com/BalancerMaxis/multisig-ops/pull/59) **Summary:** > Due to the recent [vulnerability disclosure](https://forum.balancer.fi/t/reentrancy-vulnerability-scope-expanded/4345), the deployment of the [ComposableStablePoolFactory-v3](https://etherscan.io/address/0xdba127fbc23fb20f5929c546af220a991b5c6e01#readContract) is configured to address the potential issues related to Balancer’s previous composable stable pools (v2).This pool uses the new pool factory and will be composed of three Euler linear pools. The underlying tokens are USDC and FRAX. These will each be wrapped through Euler’s market to earn LPs additional yield. 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. The gauge can be uncapped based on the contents being all large cap stable tokens. **References/Useful links:** > Euler: Link to: > • [Website](https://www.euler.finance/) > • [Documentation](https://docs.euler.finance/) > • [Github Page](https://github.com/euler-xyz) > • [Communities](https://forum.euler.finance/) > FRAX: Link to: > • [Website](https://frax.finance/) > • [Documentation](https://docs.frax.finance/) > • [Github Page](https://github.com/FraxFinance/frax-solidity) > • [Communities](https://discord.gg/MTZu6Hf57d) - Discord link > USDC: Link to: > • [Website](https://www.circle.com/en/usdc) > • [Documentation](https://developers.circle.com/docs/what-is-usdc) > • [Github Page](https://github.com/centrehq/centre-tokens) > • [Communities](https://www.coingecko.com/en/coins/usd-coin) - Coingecko link **Protocol Description:** > Euler is a permissionless lending protocol custom-built to help users lend and borrow digital assets. This provides yield bearing sources for various tokens, this case the stablecoins listed above. USDC is the dollar backed stablecoin issued by Circle. **Motivation:** > Balancer’s heavy interest in taking over the yield bearing token space and increased capital efficiency through linear and boosted pool architecture continues to take effect. This provides better trading routes on the protocol and more sustainable pool options for liquidity providers to place their funds. The great migration as we are going through now will harbor many more boosted pool options for users and Balancer to tap into a wide variety of yield sources. Euler is providing the capacity for various tokens outside of bb-euler-USD, one being FRAX in this pool. **Specifications:** 1. **Governance:** USDC are centralized and does not have a governance forum. Euler’s governance details can be seen [here](https://docs.euler.finance/euler-governance/getting-started). FRAX governance process can be seen [here](https://docs.frax.finance/smart-contracts/governance) and their snapshot [here](https://snapshot.org/#/frax.eth). 2. **Oracles:** This pool only relies on the rate providers of the linear pools to inform when yield is earned. 3. **Audits:** See Euler’s [here](https://docs.euler.finance/security/audits) FRAX See [here](https://docs.frax.finance/other/audits) 4. **Centralization vectors:** USDC is inherently centralized. FRAX governance process is highlighted above, and their stability mechanism is described [here](https://docs.frax.finance/amo/overview). Also their decentralization ratio is described [here](https://docs.frax.finance/amo/decentralization-ratio-dr). 5. **Market History:** See USDC [here](https://www.coingecko.com/en/coins/%5D(https://www.coingecko.com/en/coins/usd-coin)). and Euler [here](https://www.coingecko.com/en/coins/euler). FRAX [here](https://www.coingecko.com/en/coins/frax). 6. **Value:** LPs & Balancer will earn the protocol fee on underlying bb-euler-FRAX and bb-euler-USDC as well as swap fees. BIP-19 will incentivize TVL to continue to grow here with trading volume and this implementation will continue to draw in new volume, as well as showcase the power of these pool types.
