Token Migration Guide

This guide will take you through the process of migrating your WMT to WMTx.

Watch the video for a step-by-step guide. Please note: this only video is only relevant for the Cardano WMT-to-Cardano WMTx upgrade now.

Preparing for the upgrade

Which wallets are supported?

The browser extension version of the Eternl wallet is the only supported wallet for the Cardano WMT-to-Cardano WMTx upgrade.

Helpful Tip! If your WMT is stored in another Cardano wallet, there’s no need to create a new wallet in Eternl. You can import your existing wallet using your mnemonic phrase (seed words). Warning: A World Mobile employee will never contact you first or ask for your seed words. Do not share your wallet’s seed words with anyone!

What if I hold WMT on chains other than Cardano?

The migration portal will only support Cardano WMT-to-Cardano WMTx upgrades. If you hold WMT on a different chain, you’ll need to bridge your WMT to Cardano using the Chainport bridge before proceeding with the upgrade.

You can access the Chainport bridge here: https://app.chainport.io/

What do I need before I start?

Before you begin, please ensure you have the following:

1. Access to your Cardano wallet on the browser extension version of Eternl. You must select the wallet with your WMT (and have DApps turned on if using the Eternl wallet). If you are using another Cardano wallet you must import that wallet into Eternl.

2. Enough ADA in your Cardano wallet to cover fees. Before you initiate the transaction, you will see the approximate ADA fee. You can always make multiple migrations, provided you have enough ADA to cover gas fees. The minimum amount of WMT you can migrate is 5 WMT. Warning: If you do not have enough ADA in your Cardano wallet to cover the gas fees you will not be able to perform the migration.

3. Make sure you are using a compatible desktop browser and that your browser has pop-ups enabled. If using Chrome, you can verify it is turned on in the browser settings. Compatible browsers are Chrome, Edge, Brave and Opera. Warning: You will not be able to migrate your tokens on a mobile device.

Performing the token migration

What are the steps to perform the token migration?

Cardano WMT – to – Cardano WMTx

1. Connect your Eternl wallet. When connecting your wallet to the portal for the first time, a pop-up window will appear prompting you to give access for your wallet to interact with the portal. Pro tip: Having trouble connecting your Eternl wallet? Make sure dAPPs are turned on.

2. If the “Prepare wallet” button is visible, click on the button and sign the transaction to consolidate your UTXOs, this will allow you to upgrade all the WMT in your wallet without issues. You must have at least 12 ADA in your wallet for this step. If you do not see this button, then you do not need to do anything and can proceed to the next step.

3. Click on “Select Network” and select the Cardano Network.

4. Enter the amount of WMT you wish to upgrade. You can make multiple upgrades, provided you have enough ADA to cover gas fees.

5. Click on “Start upgrade of WMT to Cardano", after confirming the details in the pop-up, click on “Confirm upgrade of WMT to WMTx (Cardano)”.

6. Sign the transaction and wait to receive your WMTx. You will see that your token upgrade has been confirmed.

What happens after the migration is complete?

Once the token migration is complete, you will see the summary of the migration. This information is saved to the wallet you used for the migration and can be viewed at any time in the “Previous Upgrades” section of the portal. Please note: You need both wallets connected to view previous migrations if you made migrations to other chains apart from Cardano.

Your tokens are sent to you immediately after the migration is complete and may appear as an incoming transaction in your destination wallet.

You will also be able to perform more migrations if needed.

How can I migrate to EVM chains now?

Since the Cardano WMT-to-EVM WMTx migration is now closed, you’ll need to use the Bridge option to migrate your upgraded WMTx from Cardano to your desired chain. Here is a link to the bridge: https://worldmobile.net/wmtx/bridge/
