Swap ETH to an ERC20 Token

Step 1 - Enable ERC20 token

note

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

First, ensure that your wallet is funded with 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.

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.

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 ETH that you want to swap for USDC. Be precise with the amount, and make sure you have enough ETH to cover the transaction fees as well.

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.

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

Step 3 - Wait for Confirmation

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

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

Swap an ERC20 Token to ETH

Step 1 - Approve ERC20 token

note

For this guide, we will swap Uniswap (UNI) to Ethereum (ETH).

tip

Swapping an ERC20 token like Uniswap (UNI) back to 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 ETH. Set the "You Pay" field to Uniswap (UNI). This indicates that you will be using UNI to obtain ETH.

Tap on "Approve UNI to Swap". This step allows the smart contract to access your UNI tokens for the swap. Wait for the approval transaction to be confirmed on the network.

Once approved, you can proceed to the next step.

Step 2 - Enter Amount to be Swapped and Confirm Transaction

Enter the amount of Uniswap (UNI) you want to swap for Ethereum (ETH). Ensure that the amount is correct and sufficient for your needs. Tap on the "Swap" button.

A confirmation screen will appear, summarizing the transaction details. Review the information carefully, then tap "Confirm" to submit the transaction. The transaction will be sent to the Ethereum network for processing.

Step 3 - Wait for Confirmation

The transaction will be processed by the Ethereum network. Depending on the network congestion, it might take a few seconds to a few minutes to get confirmed.

Once confirmed, you will see the ETH balance updated in your wallet.
