Tutorial: How To Borrow Assets On Aave (Polygon Network)

What is Aave?

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.

What is Polygon?

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. Polygon aims to provide faster and cheaper transactions on Ethereum using Layer 2 sidechains, which are blockchains that run alongside the Ethereum main chain.

How to get funds onto the Polygon Mainnet

How to Setup Metamask for Polygon Mainnet

  • Open MetaMask in your browser;
  • Click on the current network “Ethereum Mainnet“.
  • Choose the option “Custom RPC” at the bottom of the list.
  • Enter the parameters of the Polygon mainnet

I recommend using Zapper to bridge funds over to Polygon from the Ethereum network.

  • Go to Zapper bridge zapper.fi/bridge.
  • Verify that you are on the “Ethereum mainnet” from your MetaMask. Specify the bottom destination network to be Polygon.
  • Choose the token you want to send on the Polygon network from the drop-down menu and the token you want to receive on Polygon.
  • Set the Transaction Speed according to how long you wish to wait for the confirmation on Ethereum. Once the transaction confirms on Ethereum, you have to wait an additional 7-8 mins for your assets to arrive on Polygon.
  • If it is your first time bridging to the Polygon mainnet you may receive a small amount of MATIC that you will need for your first transactions.

What is Aave Polygon?

Aave recently implemented their protocol on the 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 borrowing!

Current supported assets: MATIC, DAI, USDC, USDT, WETH, WBTC, AAVE.

A step-by-step guide on how to borrow funds on Aave Polygon

After you have deposited your assets for lending on the Aave protocol, you can borrow against your deposited assets from the Aave protocol and pay a small interest on the loan.

Navigate to the Borrow tab and select the asset you want to borrow.

For example: clicking into the USDT market will bring up the USDT overview. The maximum loan to value percentage gives you the maximum amount of an asset you can borrow. You can adjust the amount you want to borrow.

Select your interest rate type.

Confirm your transaction.

After your confirm your transactions, you'll be brought to your Dashboard. https://app.aave.com/dashboard/borrowings

In my dashboard you can see that I have borrowed 100 USDT using 446 deposited MATIC as collateral.

Congratulations on successfully borrowing assets from the Aave Polygon market!
