How to Create a Nodle Cash Wallet
v0.1.0 June 9 2020
v0.2.0 Oct 15 2020 - updated to new UI


Go to, select Nodle Mainnet, and install the Polkadot chrome extension to create an account.


Nodle has migrated from the Stellar blockchain to our own, native Nodle Chain. Nodle is built upon Polkadot Substrate, and if you’re interested you can read a lot more about how it works here. We decided to migrate for a couple of reasons; primarily being that with a native blockchain, we can enable the features outlined in our Nodle white paper (like proof of connectivity, and our own decentralized PKI), while maintaining control over our own destiny.
Stellar enabled us to build a powerful MVP (Minimum Viable Product) and prove that we could build a business around incentivized IoT connectivity. It’s time for the next step. It is our pleasure to introduce the Nodle Chain. The Nodle chain is faster, more decentralized, and add more utility to your Nodle Cash Cryptocurrency (Like built in, decentralized certificates).

How to Create a Native Nodle Wallet

Nodle is built upon Polkadot Substrate, making it compatible with most Polkadot wallets. For this tutorial, we will use the official wallet.
Ledger support is coming soon, and we will update accordingly.

Step 1: Go to the Web Wallet

Note: We recommend using a Chrome based browser like Chrome or Brave. If you are using Brave (which you should be) please turn off ‘shields’ as it can cause errors.

Step 2: Make Sure You are Running The Nodle Chain Mainnet

Sometimes the Wallet will default to another blockchain (As we interoperate with the Polkadot Ecosystem. If So Go to the top left and select the Nodle Netowrk"
a. Click on the drop down menu, and scroll down to where it says ‘Test Networks’ to find the Nodle Chain:
Finally. Click "Swtich" to initiate the connection.
If you are already running the Nodle Chain, Click “Cancel” to close the window.
If you are Not on the Nodle Chain Mainnet (for example you are on the Nodle Arcadia Testnet or Polkadot), Simply select “Nodle Chain” from the dropdown, and “Save and Reload”

Step 3: Set Up the Polkadot.js Extension:

a. There are a few ways to create an account; we are going to recommend the most user-friendly way.
b. Install the Polkadot-js extension, which is similar to Ethereum’s Metamask, except it does’t do this.
You can review the source code here:
c. Install the chrome extension:

Step 4: Create an Account

Now, go back to the wallet and reload. There may be a popup asking for your permission to connect.
If the Polkadot Add on is not showing, Simply click Extensions, and pin to your browser (Then click the extension to open)
a. Follow the directions to generate your account, by clicking "+":

b. SUPER IMPORTANT: You have generated 12 words. Keep them extremely safe. If you lose these words, all of your funds will be lost. If someone else gets them, they can steal all of your crypto.

Note: We recommend writing your words on waterproof paper and storing them in multiple, secure locations.
You can use a password manager. Some good ones are:
  • - Keypass (Open Source) Keypassx on Mac.
  • - 1Password
  • - Dashlane
  • - Lastpass
  • - Apple Keychain (not easy to use)
  • Apple Notes
  • Google Keep
  • Microsoft Word document
  • Your Yahoo email account
If you lose your seed words, we have no way to recover them.
c. Now that you’ve saved your seed words securely, give your account a name, and
d. Add a strong password. We recommend using a long, randomly generated password, stored in a password manager.

You’ll be asked to give permission for the webpage to access the Polkadot-js chrome app. Please allow. If you have closed the webpage, you will be asked to give your password.

You’re all set!

It will look something like this:
Nice work! You’re all ready to go. Bookmark this page and keep your seed words very safe.


I've done all these steps and my account still doesnt show up?
Sometimes you may have to update the wallet metadata to make your account show up. We'll do our best to keep the wallett updates to the latest settings. You would see something like this:
Follow the link to the "Settings" Page, and click "Update Metadata"
You can now reload the page and the error should be gone!
