</aside>

1. What’s MAI?

• MAI is the largest decentralized stablecoin application on Polygon PoS. It allows users to mint stablecoins (MAI) against decentralized collaterals like ETH and ETH LSTs. There are numerous options for MAI loans, with most offering predictable fixed interest lending rates.

2. Is MAI on Polygon PoS Isolated?

• Yes. MAI on Polygon PoS is isolated on three levels:

1. On the users level: Vaults are isolated from each other. No one can borrow from other user collateral nor from different assets.
2. On the protocol level: QiDao is non-custodial. The protocol doesn’t have access to users funds which are always available to be redeemed.
3. On the chain level: Polygon PoS was once connected to other chains, but since Governance approval of **QIP221: Eliminate All Bad Debt on Polygon PoS** it’s fully isolated in compliance with QiDao’s Chain Risk parameters.
