MIR-6┃Add LINK as collateral on Mimo on Polygon

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

Rationale : Chainlink is a network aiming to develop an oracle infrastructure. The objective of the oracles is to bring information from the outside world to the blockchain, by integrating data in a Smart Contract that protocols will read afterward. All types of information can be made available. The ICO of the ChainLink service took place in September 2017.

ChainLink now secures nearly $39,9B of the TVL in the DeFi ecosystem: we count big names like Aave, Compound, etc.

You can learn more about Chainlink in their documentation / whitepaper.

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

Token metrics & Risk assessment:

Smart Contract risk: B The code has 3 audits from Nick Johnson, Quantstamp and SigmaPrime. Chainlink has $39,9B total value secured. LINK has generated more than 3M transactions since its launch on Polygon in January 2021.

Counterparty risk: B+ Chainlink launched on Ethereum in September 2017 on Ethereum and is now the oracle leader of the market. There is no mint function in the Token smart contract, so, the team can't mint token and the maximum supply can't be changed. There are currently 31k holders on Polygon.

Market Risk: C+ The token is available on top exchanges with nearly $4,3B market cap with a daily volume of $500K on Polygon although a large share of LINK’s supply is staked. The liquidity available on Polygon is nearly $5M.

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

Liquidity Risk of PAR on Polygon: A- The PAR-USDC UniV3 pool has 632K$ in concentred liquidity, composed of 20% PAR and 80% USDC at the time of writing. The 2eur Curve pool has 910k$ in liquidity, composed of 52,76% PAR and 47,24% jEUR at the time of writing. The 4eur Curve pool has 762k$ in liquidity, composed of 19,28% PAR, 18,09% jEUR, 39,89% EURS and 22,74% EURT at the time of writing. The MIMO-PAR Balancer pool has 172k$ in liquidity, composed of 80% MIMO and 20% PAR.

This provides the following price impact on the following trade sizes:

• 1000 USDC → PAR: 0.06%
• 10000 USDC → PAR: 0.13%
• 25000 USDC → PAR: 0.25%
• 50000 USDC → PAR: 0.44%

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