How to Add Liquidity in Cetus Pools

Example: How to add liquidity to the APT/USDC pool (Wormhole)

Preparation:

Make sure that you have $APT and $USDC or the relevant tokens of the pool you want to add liquidity to and to pay for transaction fees. It’s also possible to add small amounts like 0.1 APT and 0.38 USDC to pools.

You can buy APT on major exchanges like Binance or Coinbase. If you don’t have USDC on Aptos available in your wallet, simply swap some APT for USDC.

Steps:

Go to the Cetus Pools page by clicking here or, when entering from the Cetus homepage, click on Pools.

Make sure you’re on the Aptos network and then click Connect.

Select Petra wallet (or the Aptos wallet of your choosing).

Approve the connection in your Petra wallet.

Click on Wormhole.

Look for the APT/USDC pool and click Add Liquidity.

Enter the amount of APT you wish to add to the pool. The required USDC amount (which has the same value as APT) will be calculated automatically. 1 APT is worth rounded $3.92 at the time of writing.
