[BIP-601] Enable Gauge for paUSD/stataPolUSDCn Pool with a 2% cap (Polygon PoS)

BAL Gauges

PR with Payload

Summary:

Enable a Balancer gauge for the paUSD/stataPolUSDCn (ECLP-paUSD-USDC-rh) E-CLP with a 2% cap on Polygon PoS.

paUSD is crypto-backed USD stablecoin issued by the Parallel Protocol.

stataPolUSDCn is the wrapped, static version of the rebasing Aave lending deposit token for aPolUSDCn on Polygon PoS.

The pool is an Elliptic Concentrated Liquidity Pool (E-CLP). E-CLPs are custom pools from Gyroscope built on top of Balancer’s pool architecture. They enable trading along the curve of an ellipse. This pool type is ideally suited for stablecoins and liquid staking tokens; is typically more capital efficient and could thus generate significant trading volume.

Protocol Description:

Parallel Protocol

The Parallel Protocol (prev. Mimo Protocol) is a Collateralized Debt Position (CDP) protocol deployed on Ethereum, Polygon PoS and Fantom. Stablecoins (PAR & paUSD) are decentralized (controlled by vMIMO holders), non-custodial, overcollateralized, and fully redeemable synthetic asset pegged to the Euro/USD fiat currency.

Motivation:

The role of the paUSD/stataPolUSDCn E-CLP pool is to increase the stability of paUSD and as well as its on-chain liquidity.

The capital efficiency of E-CLPs will help to quickly bootstrap a liquidity network for paUSD. This hub-and-spoke network will enable a liquid secondary market for paUSD & stataPolUSDCn to make it easier to exit from/ enter into paUSD.

By using E-CLPs a comparably small amount of initial capital can provide a disproportionately deep market for paUSD & stataPolUSDCn. The E-CLP’s efficiency gains are possible due to:

  • Customizable liquidity profiles: Using the curve of an ellipse enables highly customizable liquidity profiles. E-CLPs can be calibrated to approximate most trading curves that would be desired. E-CLP curves can be tailored to have certain regions of low price impact and other regions of high price impact.
  • Price bounds: The E-CLP concentrates liquidity within price-bounds that enable the E-CLP to be highly capital-efficient. Functionally, this works by enabling arbitrary truncation of liquidity profiles from a given trading curve. In effect, the capital efficiency comes from bounding the trading curve to an expected trading range of the assets.

A few notes:

  • PAR (the Parallel EURO stablecoin) already have a gauge on Balancer Polygon: 2eur (PAR)
  • paUSD (the Parallel USD stablecoin) already have a gauge on Balancer Ethereum: e-cs-kp-USD
  • Mimo Labs has started building positions in AURA (±554k $vlAURA) & BAL and the Parallel Protocol treasury currently holds 23k $vlAURA.
  • Mimo Labs is still buying AURA which will be locked to incentivize the liquidity.
  • MIMO (the Parallel governance token) already gauges on Balancer Ethereum & Polygon: p-MIMO/WETH 80/20 / MIMO/WETH 80/20

Specifications:

  1. Governance:
  • Parallel Protocol: none on-chain governance (vote via snapshot) and decisions are executed through a ⅝ multi-sig (4 team members and 4 dao members elected by vMIMO holders).
    • Polygon PoS: 0x2046c0416A558C40cb112E5ebB0Ca764c3C5c32a
    • Ethereum: 0x25Fc7ffa8f9da3582a36633d04804F0004706F9b
    • Fantom: 0x174162ddecE9d0b7B68fd945e38c3372C4C818ba
  • Aave ; stataPolUSDCn: Aave has onchain governance (more here)
  1. Oracles:
  • Parallel mainly uses Chainlink price feeds for all its collateral assets.
  • stataPolUSDCn:
    • rateProvider (for stataPolUSDCn ): 0x7d10050F608c8EFFf118eDd1416D82a0EF2d7531
    • allows to control for a price drift from accruing yield by using rate providers to first convert from yield accruing tokens to the underlying.
  1. Audits:
  1. Assets & Centralizing vector:
  • paUSD has a debt limit on each collateral, is partially collateralized by stataPolUSDCn and the ownership of the Parallel protocol and is held by a 5/8 multisig with 4 signers from Mimo Labs and 4 signers elected by vMIMO holders.
  • stataPolUSDCn: is the wrapped, static version of the rebasing Aave lending deposit token for stataPolUSDCn on Polygon PoS
  1. Market history:
  • paUSD has been live since September 2023 (on Ethereum); paUSD is soft pegged to USD.
  • stataPolUSDCn: has been live since November 2023 on Polygon PoS.
  1. Value:
  • The paUSD/stataPolUSDCn E-CLP pool will act as the main route for arbitrages and the use cases mentioned above (on-chain liquidity, etc.).
