Summary:

Enable a Balancer gauge for the USDp/USDC (USDp-USDC) StableSurge pool with a 2% cap on Base.

USDp is fully backed by a basket of correlated assets and issued by the Parallel Protocol.

USDC is fully backed by cash & cash-equivalent assets and issued by Circle.

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.

Protocol Description:

Parallel Protocol

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

Motivation:

The role of the USDp/USDC StableSurge pool is to increase the on-chain liquidity of USDp, and connect the Parallel and Circle ecosystems.

The capital efficiency of StableSurge pools will help to quickly bootstrap a liquidity network for USDp against USDC.

By using StableSurge a comparably small amount of initial capital can provide a disproportionately deep market for USDp against USDC.

A few notes:

• Mimo Labs, a contributor of the Parallel Protocol built positions in AURA (1M vlAURA), used to vote for Parallel pools.

• The Parallel Protocol treasury currently holds ±90k vlAURA, used to vote for Parallel pools.

• The Parallel Protocol 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 Protocol: none on-chain governance (vote via snapshot) and decisions are executed through a ⅝ multi-sig (elected by sPRL holders).

• Circle: USDC is a centralized entirely controlled by Circle.

2. Oracles:

• Parallel rely on Chainlink & Redstone price feeds for mint & burn.

• Circle doesn’t rely on oracles for mint & burn.

3. Audits:

• Parallel: https://docs.parallel.best/resources/security-audits

4. Assets & Centralizing vector:

• Parallel: The DAO Multisig can upgrade all USDp related contracts. Part of the backing of USDp may be centralized assets, which is not the case right now.

• Circle:

5. Market history:

• USDp has been live since August 2025 on Base; USDp is pegged to USD.

• USDC has been live since August 2023 on Base; USDC is pegged to USD.

6. Value:

• The USDp/USDC stable pool will act as the main route for arbitrages and the use cases mentioned above (on-chain liquidity, etc.).
