Instantly Swap cTokens on Compound
Tutorial: Instantly Swap cTokens on Compound
Passive income is the money that you earn in a way that requires little to no effort. In the DeFi world, the easiest way to earn passive income is by supplying/depositing an asset to lending protocols to earn interests in return.
In our previous article, Passive income combo, we introduced you what interest-bearing tokens are and how to get some of them to earn passive income. In this article, we will walk you through further how to swap between Compound cTokens to get higher APY in return.
How to swap between cTokens?
There are three ways to swap cTokens. Two of them are for users who don’t have debt on Compound and one for those who do.
No-debt cToken swapping
If you don’t have any debt on Compound and want to swap your cTokens to another cTokens to get higher APY, there are two approaches you can put into practice:
- Basic level: Build combo manually
- Pro level: Instant swap panel. Skip building. Just use Furucombo’s latest feature on the Explore Page.
1) Basic level: Build combo manually

Step 1: Withdraw cToken A from Compound

Step 2: Swap Token A to Token B

Step 3: Supply Token B to Compound and get cToken B
Copied!
Basic level: Use Furucombo‘s combo to swap cTokens
2) Pro Level: Instant swap panel
Furucombo has simplified the basic level into a setup form. There, you can swap cTokens with ease by selecting the cTokens (From & To) and entering the amount. In the setup form, you can also clearly see the before-and-after change of APY.

cToken swapping with debts…
If you have debts on Compound and you want to swap your cTokens from one to another, well… it’s a bit complicated. Get ready to wrap your head around or you may jump to the end of the story → use our pre-built Compound Collateral Swap Combo to execute the swapping.
You may wonder, why can’t you use the previous swap cToken combo to do the same? The answer is because you have debts on Compound. Your cTokens are, therefore, collaterals, and they are locked until a) your debts are paid or b) you supply more funds to increase the collateralization ratio. The strategy below takes b option. We use flashloan to double your supply volume first and withdraw original collateral to pay back the flashloan. In this case, no upfront funds are needed.
Compound Collateral Swap
When using this combo set, you may notice two cubes that you don’t see often, “Return Funds” and “Add Funds”. They are there for a reason so please, don’t delete them.
“Return Funds” cube means moving funds from Furucombo’s proxy contract to user’s wallet. And conversely, “Add Funds” cube means moving funds from user’s wallet to Furucombo’s proxy contract.
In the example here, after you supply USDC to Compound, the cUSDC is on Furucombo’s proxy contract. You need to use the “Return Funds” cube to transfer cUSDC to your wallet so that your supply position can be doubled. Then, because your cBAT is locked in your wallet until you increase your supply position, you need to use the “Add Funds” cube to send cBAT to Furucombo’s proxy contract right after receiving the cUSDC.
Doesn’t it sound like everything is reversed? Because it is. You receive the target cToken first and you send your original cToken later to swap.
1
You hold cBAT and you want to swap them to cUSDC:
2
Step 1: Flashloan borrow USDC
3
Step 2: Supply USDC and get cUSDC
4
Step 3: Return cUSDC to your wallet
5
Step 4: Send cBAT to Furucombo
6
Step 5: Withdraw cBAT to BAT
7
Step 6: Swap BAT to USDC
8
Step 7: Repay USDC to flashloan with fee
