The basics of lending in DeFi

DeFi allows people to borrow cryptoassets from a pool of lenders. The lenders receive yield from the interest borrowers pay. If you are new to the idea of lending or borrowing, please read the following article: What is crypto lending?

Introduction to Aave

Aave, a leading DeFi DApp, exists on multiple chains, including Ethereum and Avalanche. The Bitcoin.com Wallet supports DApps on both chains through WalletConnect.

You can read more about WalletConnect here.

Here’s a guide for how to use WalletConnect.

Supplying assets to Aave allows you to do two things:

  1. Earn interest on your deposit (APY).

  2. Use your deposited cryptoassets as collateral for a loan.

The importance of Loan-To-Value

The ratio between a loan and collateral is called Loan-To-Value, or LTV for short. LTV is only important if you intend to use deposited assets as collateral to borrow.

The LTV ratio defines the maximum amount of assets that can be borrowed with a specific collateral. For example, imagine you deposit ETH as collateral. The LTV can change over time, but let’s imagine it has an LTV=75%. This means that for every 1 ETH worth of collateral, you will be able to borrow 0.75 ETH worth of the corresponding asset, such as DAI or USDC.

High volatility cryptoassets like Wrapped Bitcoin, Ethereum, and particularly other lesser known coins can see rapid decreases in value. If you use these assets as collateral and the value of those assets rapidly depreciates, you can be liquidated before you can add more collateral. Stablecoins are much less volatile, and are the preferred collateral for that reason.

In Aave, it’s important to watch the Health factor of your loans.
