Aave is an open source and non-custodial liquidity protocol for earning interest on deposits and borrowing assets. It lets users lend or borrow cryptocurrency without going through a centralized intermediary (like a bank, financial institution, or centralized exchange).
Depositors earn a passive income when they provide liquidity to the market by depositing assets. Borrowers are able to borrow assets to obtain liquidity (working capital) without selling their assets. Borrowers pay interest on their loans. Usually, people borrow due to unexpected expenses, to leverage their holdings or for new investment opportunities.
Polygon is a protocol and a framework for building and connecting Ethereum-compatible blockchain networks. Polygon’s network leverages the security of the Ethereum network and uses Chainlink as a price oracle. It is a scaling solution for Ethereum.

How to bridge funds to the Polygon Mainnet
I recommend using Zapper to bridge funds over to the Polygon mainnet from the Ethereum mainnet.
Aave recently implemented their protocol on Polygon mainnet, which means that transactions for any Aave Polygon lending or borrowing are lightning fast and have low transaction/gas costs.
Note: Polygon will be paying out 0.5% of the total supply of MATIC in rewards for borrowing and lending funds between Jun. 14, 2021 and Apr. 13, 2022. So you can even get rewarded in WMATIC by lending!
Current supported assets: MATIC, DAI, USDC, USDT, WETH, WBTC, AAVE.
