Swap ZK ETH to an ERC20 Token​

Step 1 - Enable ERC20 token​

note

For this guide, we will swap zkSync Ethereum (ETH) to USD Coin (USDC).

First, ensure that your wallet is funded with zkSync Ethereum (ETH). This is the base currency needed for the transaction. Tap on the "Add Token" toggle located on the upper right corner of the screen.

Tap on Swap

Search for the ERC20 token you want to swap to, in this case, USD Coin (USDC). Type "USDC" into the search bar. Once you find USDC, slide the toggle to the right to enable it in your wallet. This makes the token available for swapping and other transactions.

Add Token

After enabling the token, you are ready to proceed with the swap.

Step 2 - Enter Amount to be Swapped and Confirm Transaction​

Tap on the "Swap" button, then select USDC from the list of available tokens. Enter the amount of ZK ETH that you want to swap for USDC. Be precise with the amount, and make sure you have enough ZK ETH to cover the transaction fees as well.

Enter ZK ETH Amount

Tap on the "Swap" button, and a confirmation screen will appear. Review the details carefully to ensure everything is correct. Once you are satisfied, tap "Confirm" to submit the transaction.

Confirm ZK ETH Swap

The transaction will be sent to the zkSync network for processing.

Step 3 - Wait for Confirmation​

After submitting the transaction, it will be broadcasted to the zkSync network. Depending on the network congestion, it might take a few seconds to get confirmed.

Pending Swap Transaction

Once confirmed, you will see the USDC balance in your wallet. Congratulations! You have successfully swapped ZK ETH to USDC.

For this guide, we will swap USD Coin (USDC) to zkSync Ethereum (ETH).

tip

Swapping an ERC20 token like USD Coin (USDC) to zkSync Ethereum (ETH) involves a token approval step to authorize the transaction.

Tap on the "Swap" button in your wallet, then select the ERC20 token you want to swap to ZK ETH. Set the "You Pay" field to USD Coin (USDC). This indicates that you will be using USDC to obtain ZK ETH.

Tap on Swap
