MIR-8┃Add DAI as collateral on Mimo on Polygon

Summary: This proposal aims to add DAI as new collateral on Mimo on Polygon.

Rationale:

The Maker Protocol is one of the largest dapps on the Ethereum blockchain. It allows users to generate DAI by leveraging collateral assets approved by the Maker Governance.

DAI is designed to minimize price volatility. It is a decentralized, unbiased and collateral-backed cryptocurrency that is soft-pegged to the US Dollar.

Users generate DAI by depositing collateral assets into Maker Vaults within the Maker Protocol. Every DAI in circulation is directly backed by excess collateral, meaning that the value of the collateral is higher than the value of the DAI debt.

To generate DAI, the Maker Protocol accepts as collateral any Ethereum-based asset that has been approved by MKR holders. MKR holders must also approve corresponding Risk Parameters for each accepted collateral.

With a supply of almost $7 billion in circulation, DAI is one of the most widely used dollar stablecoins in DeFi.

You can learn more about these mechanisms in their documentation / whitepaper.

Once the vote is accepted on Snapshot, we will determine the associated liquidation ratio, minimal collateral ratio, debt ceiling, liquidation bonus on a second MIR discussion.

Token metrics & Risk assessment:

Smart Contract risk: B+ All accepted collateral assets can be leveraged to generate DAI in the Maker Protocol through smart contracts called Maker Vaults. The smart contracts are known as Collateralized Debt Positions (CDPs) and the vaults are inherently non-custodial. DAI has generated more than 34M transactions on Polygon.

Counterparty risk: B+ Users interact with Vaults and the Maker Protocol directly, and each user has complete and independent control over their deposited collateral as long the value of that collateral doesn’t fall below the required minimum level (the Liquidation Ratio, discussed in detail below). There are currently 685k holders on Polygon.

Market Risk: B+ DAI has a $6,5B market cap. Furthermore the price is correlated to the USD and over-collateralized at 140%. For this reason, we consider the risks of DAI mitigated by his over-collateralized asset such as USDC, ETH, BTC, etc. which have the highest market capitalizations and trading volumes of the MRC-20 tokens. The liquidity available on Polygon is nearly $12,4M with approximately $3M of volume per day on Polygon.

Chain Risk : A Polygon had 0 outages over the last 6 months. (https://polygonscan.com/blocks)

Liquidity Risk of PAR on Polygon: A- The PAR-USDC UniV3 pool has 592K$ in concentrated liquidity, composed of 50% PAR and 50% USDC at the time of writing. The 2eur Curve pool has 848k$ in liquidity, composed of 41,7% PAR and 58,3% jEUR at the time of writing. The 4eur Curve pool has 382k$ in liquidity, composed of 16,7% PAR, 19,7% jEUR, 37,4% EURS and 26,1% EURT at the time of writing. The MIMO-PAR Balancer pool has 136k$ in liquidity, composed of 80% MIMO and 20% PAR.

This provides the following price impact on the following trade sizes: 1000 USDC → PAR: 0.01% 10000 USDC → PAR: 0.08% 25000 USDC → PAR: 0.21% 50000 USDC → PAR: 0.41%

Overall Risk : B+ The Overall Risk is the average of the points mentioned above.

Means: Human resources: Multisig DAO signers will need to sign and execute transactions to add DAI as collateral on Mimo. Treasury resources: There is no cost for the treasury to add DAI on Mimo Polygon.

Technical implementation: Add DAI in the ConfigProvider Contract with all parameters decided by the Mimo governance. Set the chainlink oracle related to the DAI: DAI/USD into PriceFeed Contract

Voting options:

• Add DAI as new collateral on Mimo on Polygon
• Against adding DAI as new collateral on Mimo on Polygon
• Abstain
