sendMessageToChild(address,bytes)# Add stMATIC as Collateral to USDCv3 Polygon Market
Using stMATIC as a collateral asset has added significant value on other lending platforms like Aave v3 (Polygon) and a popular leveraged staking strategy increasing utilization rates for MATIC. For Compound, stMATIC offers a good collateral option because of its extensive use and composability on Polygon.
## stMATIC - Key Reasons to List on Compound
stMATIC is deeply integrated with DeFI projects such as Aave and Balancer.
stMATIC TVL has grown to 135M+ MATIC steadily ever since its launch.
There is 40M+ stMATIC on Polygon that haven't been deployed on DeFi yet, which offers a large TVL opportunity for Compound
## Proposed Parameters
Liquidity - stMATIC currently has a TVL of 135M+ MATIC staked.
This proposal is to set the parameters for stMATIC as below based on [Gauntlet's recommendations](https://www.comp.xyz/t/gauntlet-recommendations-stmatic-and-stmatic-listing-on-polygon-compound-v3/4397)
supplyCap: 8,000,000
borrowCollateralFactor: 60%
liquidateCollateralFactor: 65%
liquidationFactor: 7%
The proposal is to be made from [this pull request](https://github.com/compound-finance/comet/pull/808/files)
## Background - stMATIC
Lido on Polygon staking solution for Polygon is stMATIC, a liquid staking solution for MATIC. Lido on Polygon lets users earn MATIC staking rewards and also enables users to participate in other Defi protocols using stMATIC while accruing rewards.
stMATIC is a token that represents your share of the total MATIC pool deposited with Lido on Polygon. As soon as you deposit MATIC on the Lido on Polygon smart contract, you receive newly minted stMATIC, based on the exchange rate at the time of staking. As the MATIC rewards get added the value of stMATIC increases.
