Adding Wallet

While we are on the testnet, we suggest you use a MetaMask wallet with WeatherXM. By following our guide, it's fairly simple to set up a MetaMask wallet and add a custom token (in our case, the WXM token) on Polygon Testnet.

note

The following guide has been written with the MetaMask browser extension in mind. The steps may vary on other platforms like the mobile app.

Step by step instructions

Installing and setting up MetaMask

MetaMask is a crypto wallet app and browser extension.

caution

Only install this wallet from the official MetaMask website!

  1. MetaMask is available to download and install on Chrome, iOS, and Android through the MetaMask website. Always check if you are using the official website to make sure you’re installing the real MetaMask extension.
  2. After installing the extension, you’ll be greeted with the MetaMask welcome page. Click [Get Started] to begin.
  3. If you’re creating a new wallet, click the [Create a Wallet] button. You can also import an existing wallet using its seed phrase with the [Import wallet] option.
  4. MetaMask will ask you if you’d like to share anonymous usage data with them to help improve the extension. Accepting or refusing this will not affect your MetaMask usage.
  5. Choose a secure password to log in to your wallet from your browser. Note that this is not your seed phrase. The password is a security measure to prevent anyone using your device from accessing your wallet. If you forget your password, you can always access your crypto with your seed phrase.
  6. After choosing your password, MetaMask will present you with information regarding your wallet’s seed phrase. Make sure to read through it if you aren’t familiar with how a crypto wallet works.
  7. You’ll now be presented with your seed phrase. Click the lock to view the words and take note of them in the correct order. Keep the phrase in a secure place (preferably offline) and never share it with anyone. This string of words is the final backup of your wallet and its contents. Click [Next] to continue.
  8. You’ll now have to repeat your seed phrase by selecting the words at the bottom of the screen in the right order. Click [Confirm] once this is complete.
  9. Your MetaMask wallet will now be set up and ready to use. Click [All Done] to view your wallet.

All steps below this point are optional

note

If you want to confirm the existence of your tokens in your preferred wallet, you need to add our ERC20 token's smart contract.

Add Polygon Network

Adding Polygon Network support to MetaMask is a mandatory step in order to add the WXM token, view activity, and make transactions. Make sure you follow our step-by-step guide below for adding the Polygon Network to MetaMask.

We will provide guidance for both Polygon Mainnet and Testnet (also called Mumbai Testnet) but as we are currently in testnet, you need to add the Testnet network.

There are two ways to do it:

  1. Using Polygonscan (Only for Desktop with MetaMask browser extension already installed)
  2. Add the Polygon network manually

Using Polygonscan

note

Please make sure you have already installed MetaMask!

This solution works only on desktop with the MetaMask browser extension already installed.

Please follow the steps to add Polygon Testnet (also known as Mumbai Testnet):

  • Navigate to mumbai.polygonscan.com
  • Scroll down to the bottom of the page and click on the button Add Mumbai Network
  • Once you click the button you will see a MetaMask notification, now click on Approve. Next, click Switch Network. You will be switched to Polygon Testnet in the network dropdown list. You can now close the dialog.

If you face any issues, Add the Network Manually (steps given below).

Add the Polygon network manually

To add Polygon Testnet (Mumbai), click on the Network selection dropdown and then click on Add Network.

It will open up a new Settings page which contains a form. You can add Polygon Testnet in the Network Name field, https://matic-mumbai.chainstacklabs.com/ in the New RPC URL field, 80001 in the Chain ID field, MATIC in the Currency Symbol field and https://mumbai.polygonscan.com/ in the Block Explorer URL field.

Once you’ve added the URL in the New Network field, click on Save. You will be directly switched to Polygon Testnet now in the network dropdown list. You can now close the dialog.

You have successfully added the Polygon Network to your MetaMask!


Add WXM in MetaMask

For the WXM token to appear in the wallet UI, you will need to add it manually. Note that your wallet can still receive tokens that haven’t been imported.

IMPORTANT NOTE

Please make sure you have already added the Mumbai-Testnet and have connected to it by following the guide above!

  1. First, you will need the following details of the WXM token in order to add it:
    1. Token Contract Address: 0xeCbbbF304fdf91cdDDA6C6643ED1300A552b691A
    2. Token Symbol: WXM
    3. Token Decimal: 18

You can verify those details on PolygonScan.

  1. On MetaMask and click [Import tokens].
  1. Paste in the WXM’s contract address and MetaMask should automatically fill in the rest of the details. If not, add them manually. To finish, click [Add Custom Token].

  2. Click [Import Tokens].

You have now successfully added the WXM token to your MetaMask wallet!
