**PR with payload** > > > https://forum.balancer.fi/t/bip-880-enable-gauge-for-usdp-mevusdc-stable-pool-wi…th-a-2-cap-avalanche/6860 # **Summary:** Enable a Balancer gauge for the USDp/mevUSDC (USDp-mevUSDC) StableSurge [pool](https://balancer.fi/pools/avalanche/v3/0xe183132786df083788915dc9053cd747aaff01a6) with a 2% cap on Avalanche. USDp is fully backed by a basket of correlated assets and issued by the Parallel Protocol. mevUSDC is a Silo Vault curated by MEV Capital. The pool is a StableSurge pool. StableSurge pools are a type of stable pool designed for assets that usually trade at nearly the same value or have a predictable exchange rate. What makes StableSurge pools different is that they use a special feature, called a hook, to automatically adjust the swap fee based on how balanced the pool is during a trade. # **References/Useful links:** ## **Parallel:** - Website: [https://parallel.best/](https://parallel.best/) - Documentation: [https://docs.parallel.best/](https://docs.parallel.best/) - Code: [https://github.com/parallel-protocol](https://github.com/parallel-protocol) - X: [https://twitter.com/ParallelMoney](https://twitter.com/ParallelMoney) - Audits: [https://docs.parallel.best/resources/security-audits](https://docs.parallel.best/resources/security-audits) ## **Silo:** - Website: [https://silo.finance/](https://silo.finance/) - Documentation: [https://docs.silo.finance/docs/users/intro/](https://docs.silo.finance/docs/users/intro/) - Code: [https://github.com/silo-finance](https://github.com/silo-finance) - X: [https://x.com/SiloFinance](https://x.com/SiloFinance) - Audits: [https://docs.silo.finance/docs/audits/](https://docs.silo.finance/docs/audits/) # **Protocol Description:** ## **Parallel** Parallel is a scalable, modular, over-collateralized & decentralized stablecoin protocol issuing USDp, a crypto-redeemable stablecoin backed by yield generating correlated assets, with cross-chain support via LayerZero. The protocol consists of a decentralized price-stability module where you mint/burn USDp at oracle price (not 1:1) against correlated assets without any cooldown. Generated yield by backing of the stablecoin is distributed to stablecoin stakers. Currently a USD stablecoin, called USDp is deployed across 16 chains: - USDp: Parallel USD Stablecoin - sUSDp: Staked USDp (4626), receive yield from the stablecoin backing ## **Silo** The Silo Protocol is a non-custodial lending primitive that creates programmable risk-isolated markets known as silos. Any user with a wallet can lend or borrow in a silo in a non-custodial manner. Silo markets use the peer-to-pool, overcollateralized model, where the value of a borrower’s collateral always exceeds the value of their loan. Silo is currently live on Ethereum, Sonic, Arbitrum, and Avalanche. # **Motivation:** The role of the USDp/mevUSDC StableSurge pool is to increase the secondary market on-chain liquidity of USDp, while connecting the Parallel, Silo & MEV Capital ecosystems. The capital efficiency of StableSurge pools will help to quickly bootstrap a liquidity network for USDp. By using StableSurge a comparably small amount of initial capital can provide a disproportionately deep market for USDp. ### **A few notes:** - Mimo Labs, a contributor of the Parallel Protocol built [positions](https://debank.com/profile/0x4a266739E40664e80470CC335120a2A1fA0B3F3f) in AURA (1M vlAURA), used to vote for Parallel pools. - The Parallel Protocol [treasury](https://pro.octav.fi/parallelprotocol/treasury) currently holds ±90k vlAURA, used to vote for Parallel pools. - The Parallel Insurance Fund holds ±1.3M AURA, used to vote for Parallel pools. - Parallel has been using Balancer since June 2021 for Parallel assets. # **Specifications:** 1. Governance: - **Parallel:** none on-chain governance (vote via [snapshot](https://vote.parallel.best/#/)) and decisions are executed through a ⅝ multi-sig ([elected](https://docs.parallel.best/governance/dao-multisigs) by sPRL holders). - **Silo & MEV Capital:** mevUSDC is governed by ⅔ [multisig](https://app.safe.global/balances?safe=avax:0xB672Ea44A1EC692A9Baf851dC90a1Ee3DB25F1C4). 1. Oracles: - **Parallel** rely on Chainlink & Redstone price feeds for mint & burn. - **Silo** mevUSDC vault doesn’t rely on oracles since it is an erc4626 vault. 1. Audits: - **Parallel** : [https://docs.parallel.best/resources/security-audits](https://docs.parallel.best/resources/security-audits) - **Silo:** [https://docs.silo.finance/docs/audits/](https://docs.silo.finance/docs/audits/) 1. Assets & Centralizing vector: - **Parallel:** The DAO Multisig can upgrade all USDp related contracts. Part of the backing of USDp may be centralized assets.. - **Silo & MEV Capital:** The Silo vault is libelled in USDC, a centralizer stablecoin developed by Circle. Circle has the ability to freeze USDC. 1. Market history: - **USDp** has been live since August 2025 on Avalanche; USDp is pegged to USD. - **mevUSDC** has been live since June 2025 on Avalanche. 1. Value: - The USDp/mevUSDC stable pool will act as the main route for arbitrages and the use cases mentioned above (on-chain liquidity, etc.). # **Contracts** - Balancer Pool (Avalanche): [0xe183132786df083788915dc9053cd747aaff01a6](https://snowscan.xyz/address/0xe183132786df083788915dc9053cd747aaff01a6#code) - USDp Token (Avalanche): [0x9ee1963f05553ef838604dd39403be21cef26aa4](https://snowscan.xyz/address/0x9ee1963f05553ef838604dd39403be21cef26aa4#code) - mevUSDC Token (Avalanche): [0x4dc1ce9b9f9ef00c144bfad305f16c62293dc0e8](https://snowscan.xyz/address/0x4dc1ce9b9f9ef00c144bfad305f16c62293dc0e8#code) - Gauge (child): [0xecff9ca9a341d591db57953b1d27c4b68d4bca77](https://snowscan.xyz/address/0xecff9ca9a341d591db57953b1d27c4b68d4bca77#code) - Gauge (root): [0x1f0ee42d005b89814a01f050416b28c3142ac900](https://etherscan.io/address/0x1f0ee42d005b89814a01f050416b28c3142ac900#code) ### Technical Specification The Balancer Maxi Omni-Sig `0x9ff471F9f98F42E5151C7855fD1b5aa906b1AF7e` will interact with the GaugeAdderv4 at `0x5DbAd78818D4c8958EfF2d5b95b28385A22113Cd` and call the addGauge function with the following arguments: gauge(address):`0x1f0ee42d005b89814a01f050416b28c3142ac900` gaugeType(string): `Avalanche` ---
