This article will guide you on how to use Compound in details, including its main features of lending and borrowing.

Compound is one of the best lending protocols on DeFi at the moment. With more than $10.7B worth of assets deposited into the protocol, Compound is well known for its efficient yet easy-to-use application.

This article will guide you on how to use Compound, including its main features of lending and borrowing.

Compound Overview

Compound is an algorithmic lending and borrowing protocol that facilitates money markets by incentivizing liquidity.

What do I mean here by “algorithmic”? It means that the interest rates are adjusted according to the demand and supply of the underlying asset. No counterparties or compromises are required in the process, making Compound decentralized.

Some notable points before using Compound

  • Compound is currently only available on Ethereum. Compound is building a Compound Chain (Gateway) on Polkadot to potentially widen its operating range.
  • When you supply your assets in Compound, you will receive a corresponding cToken by an exchange rate. This exchange rate will increase over time, so you can earn interest by simply holding the cToken on any wallet.
  • Check all the details such as APY or Collateral Ratio carefully so as not to be liquidated. It is compulsory when you borrow assets in DeFi.

FAQ about Compound

How much should I borrow?

To avoid liquidation, you should borrow only a reasonable amount. Depending on the assets that you are borrowing, there will be different Liquidation Ratios and Collateral Ratios. I recommend that you keep the Liquidation Price at about 50% (for normal tokens) and 60-65% (for stablecoins) of that asset’s market value. This is a pretty safe threshold to borrow assets.

For example: If I borrow Aave (a normal token) at $280, I will adjust the amount of Aave I borrow so that its Liquidation Price will be around $140 (50%). 

However, remember that this number should only be treated as an advisable standard. You should adjust the amount based on the assets you are borrowing and the assets you are collateralizing, considering its price fluctuation and price spread.

How much can I earn by lending/supplying?

Depending on the protocol you are using and the asset you are depositing, the APY will be different. 

Do remember that the APR (APY) you earn by lending is usually much lower than that by farming/staking. Conventionally, the APR on lending protocols ranges from 1% to 3%.

You should check all possible yields on different platforms and protocols to make the most profitable decision.

Do I have to lock my assets when lending/supplying?

No, you don’t. You can withdraw your assets anytime you want, given that you are not borrowing any assets and/or having any debt.

How much do I have to pay after borrowing?

The borrowing fee varies depending on the assets you are borrowing, and the application you are using. Although some assets are supported with a 0 borrowing fee, the number usually ranges from 5-7%.

You can pay this fee in multiple assets based on the list that the protocol supports.


And that is all you need to know in order to use Compound. Hopefully, this article can effectively support users in using Compound with the Coin98 Mobile Wallet and the Coin98 Extension Wallet.
