How to change the primary currency in MetaMask?

Understanding the Concept of Primary Currency in MetaMask

MetaMask, a popular cryptocurrency wallet, allows users to interact with the Ethereum blockchain and other compatible networks. One key feature is the ability to set a primary currency, which determines the default token displayed in your wallet balance. By default, this is usually Ether (ETH), but it can be changed to any supported ERC-20 token.

The primary currency setting affects how your wallet interface appears, especially on the main dashboard. While you can still view all tokens in your wallet, the primary currency will appear most prominently. This is particularly useful for users who frequently transact in a specific token rather than ETH.

It's important to note that changing the primary currency does not alter the actual assets in your wallet — it only changes how they are displayed.

Accessing MetaMask Settings to Change Primary Currency

To begin the process of changing the primary currency, you need to access the settings within the MetaMask extension or mobile app. Here’s how:

• Open your MetaMask wallet.
• Click on your account icon located at the top-right corner.
• From the dropdown menu, select Settings.
• In the left sidebar, click on Advanced.

In the Advanced section, you’ll find an option labeled 'Primary currency denomination.' This is where the change takes place. The options available include ETH, USD, or any custom token you’ve added to your wallet.

Make sure that the token you wish to set as primary is already added to your MetaMask wallet. If not, you’ll need to add it manually before proceeding.

Adding a Custom Token to MetaMask

If the token you want to set as your primary currency isn’t already in your wallet, you must add it using the Add Token feature. Follow these steps:

• Navigate back to the main wallet interface.
• Scroll down to the Assets tab.
• Click on Add Token.
• Select Custom Token.
• Enter the token contract address, symbol, and decimals of precision.
• Click Next, then Add Tokens.

Once the token is successfully added, it will appear under your list of assets. Now you can proceed to set it as the primary currency from the Advanced Settings menu.

Ensure the contract address is correct to avoid adding fake or incorrect tokens. Always verify addresses from official sources.

Changing the Primary Currency to a Specific Token

After confirming that the desired token is in your wallet, follow these steps to make it your primary currency:

• Go back to Settings.
• Click on Advanced in the left-hand menu.
• Under Primary currency denomination, click the dropdown menu.
• Select the token you wish to use as your primary display currency.
• Close the settings and return to your wallet dashboard.

You should now see the selected token displayed prominently as your main balance. This change applies across all networks you're connected to, so ensure that the token exists on the networks you commonly use.

Keep in mind that if you switch networks and the token isn’t available there, MetaMask may revert to showing ETH or USD instead.

Reverting Back to ETH or USD as Primary Currency

At any time, you can revert back to using ETH or USD as your primary currency. The process is the same as changing it to another token:

• Access Settings > Advanced.
• Locate the Primary currency denomination option.
• Choose either ETH or USD from the dropdown.
• Confirm the change and return to your wallet.

This flexibility allows users to toggle between different currencies based on their current needs without affecting the underlying assets.

If you frequently switch between tokens, consider keeping your primary currency as USD for a stable value reference point.

Troubleshooting Common Issues When Changing Primary Currency

Sometimes users may encounter issues when trying to change their primary currency. Here are some common problems and solutions:

• Token Not Showing Up in Dropdown: Ensure the token is added to your wallet and fully loaded. Refresh the page or restart the MetaMask extension if needed.
• Incorrect Balance Displayed: Double-check that you’re on the correct network where the token is valid.
• Dropdown Menu Not Working: Try updating MetaMask to the latest version or clear browser cache if using the extension.
• Token Disappears After Network Switch: If the token doesn't exist on the new network, it won't display. Add the token again on that specific network if necessary.

If none of these steps work, try reinstalling the MetaMask extension or reaching out to their support team.

Frequently Asked Questions

Can I set multiple tokens as primary currencies simultaneously?No, MetaMask allows only one primary currency to be displayed at a time. However, you can switch between different tokens as needed through the settings.

Will changing the primary currency affect gas fees?Gas fees are always paid in the native currency of the network you're using (e.g., ETH on Ethereum). Changing the primary currency has no impact on transaction fees.

Is it possible to change the primary currency on the MetaMask mobile app?Yes, the MetaMask mobile app supports changing the primary currency. The steps are similar to the desktop version: go to Settings > Advanced > Primary currency denomination.

Does changing the primary currency affect dApp interactions?No, dApps will still require transactions in the native currency of the network. The primary currency setting only affects how balances are displayed in your wallet.
