Frequently Asked Questions (FAQ)

What is the Nodle network?

The Nodle network is a decentralized Bluetooth network built with smartphones by thousands of people like you. Every smartphone serves as a node of the network helping transmit data from Bluetooth devices to their owners. The network is built using Bluetooth Low Energy (BLE), making it mobile-data friendly and power-efficient.

How is the Nodle network used?

The Nodle network is currently being used for tracking an asset's location, primarily through iBeacons. It allows tracking parcels, finding lost or stolen electronic devices, locating leased vehicles, etc. In the future, it can be used to manage any Bluetooth device, for example, weather monitors, traffic lights, health monitors, etc.

How does the Nodle app work?

All you need to join the Nodle network is to install the Nodle app and enable Bluetooth and location sharing in the phone settings. Once you do this, your phone becomes a node of the Nodle network, helping transmit data from Bluetooth devices around you. The information is then sent back to the owner of the Internet-of-Things (IoT) device. Your personal data is not shared with the owner.

To better understand, increasingly more and more Internet-of-Things (IoT) devices with sensors all around us need to transfer data back to their owners but only have Bluetooth radios in them (e.g., no WiFi or LTE). The Nodle app uses the Bluetooth radio in your phone to connect to these IoT devices and securely transfers the data from Bluetooth to LTE to whatever company owns the device (e.g., an e-Scooter, a pet with a tracking device, a cargo with a sensor). The data collected includes mac address, geolocation, broadcasted beacon, and any specific data, which can be sent to/from a device depending on its type.

How is my location used?

The location of your device is only used to compute your rewards based on your contribution to network coverage, and locate Bluetooth devices on request of their owners. The location is never used for any other purpose, shared or sold.

What is the NODL token?

NODL is the native cryptocurrency of the Nodle network. It creates an incentive for participants like you to come and grow the network.

How are rewards calculated and allocated?

The amount of rewards you receive depends on your contribution to building the Nodle network and is calculated based on:

  1. App time availability - the percentage of time the Nodle app has been running on a phone and connected to the Internet.
  2. Bluetooth availability - a metric indicating if the Bluetooth has been switched on on a phone.
  3. Geographical coverage - your contribution to the network coverage in visited H3 tiles, which is calculated based on the number of nodes in each H3 tile.

The total amount of rewards is set per day and is shared among all network nodes. It means that the amount of rewards you receive will reduce over time as the network grows. However, the bigger the network, the higher the NODL token price on the market. You can check the current token daily issuance here

Rewards are calculated and allocated every 4 hours based on your and network activity from the time of the previous allocation.

How can I earn more rewards?

Our app is specially designed to run at all times in background without impacting the user experience. All you need is to make sure that your phone and the app are configured properly, particularly:

  1. Bluetooth is switched on, and the Bluetooth permission is granted to the app
  2. The location sharing permission is set to 'Always allowed'
  3. The battery optimization setting is switched off for the app (applicable only for Android phones)
  4. The developer mode is switched off on the phone

You can check granted permissions in the phone settings > Nodle app > Permissions, and all other settings in the respective phone settings. The app will also notify you if some critical permissions are missing.

If your device and the app are configured properly you can use the following tips to maximize your rewards:

  1. Make sure the app runs 24/7 either in foreground or background
  2. Move as much as possible in order to create a wider coverage
  3. If you have multiple devices with the Nodle app, then place them in different locations. Otherwise, your rewards will be split between those devices.

How can I cash out or exchange my tokens?

First, we recommend you consider your tokens as an investment and keep them for the future. You will be able to sell them anytime, so there is no need to hurry.

If you want to sell or exchange your tokens, you can do it on any crypto exchange on which the NODL is listed. You can check the list of exchanges and the current token price on the CoinMarketCap or on the CoinGecko. You need to deposit your tokens into your exchange account to trade them. To do this, you need to send your tokens to the deposit address provided by the exchange. Once the exchange receives tokens, you can trade them. Please check the deposit instructions of the selected exchange before sending your tokens.

How can I import my wallet from the Nodle app to the web?

Detailed instructions on how to import your account from the app to the web.

How can I import my wallet to other wallets, like Polkadot JS, MetaMask, etc.?

We recommend you use Talisman for managing your wallet on desktop. However, third parties such as Polkadot JS, SubWallet, or Nova should be compatible as well if you use a non-legacy Nodle wallet.

What is a public key? Where can I find my public key?

A public key is a public address of your account. It can be shared with people so they can send you some Nodle Cash. This is similar to your email address when people want to send you an email.

You can find your public key in the Nodle Cash app by clicking the "Receive" button below your balance.

What is a legacy Nodle wallet?

The Nodle app has two wallet systems: legacy and non-legacy. Legacy Nodle wallet might be a bit more complex to import to other wallets supporting NODL, or it might not be compatible with other wallets at all. Other than that, it is a valid wallet, and you can use it as before.

If you have just joined the Nodle network, you have a non-legacy wallet. You can check it if you navigate to the screen with your public key by clicking the "Receive" button. The app will indicate whether you are using a legacy wallet or not. If it does not say anything, you are using a non-legacy wallet.

If you use a legacy wallet, we recommend you switch to a new one.

How can I switch to a new wallet from a legacy one?

The app can automatically upgrade your wallet during the wallet import if you have 0 balance. In this case, you will get a new public key, which you need to share with your peers to receive transfers. Your 12-word recovery phrase will not change, so you don't need to back up your wallet again. Your rewards and transfer history will start from scratch.

Otherwise, it would be best to switch to a new wallet manually. It means that you need to create a new wallet and transfer all your tokens there. Here is what you need to do:

  1. Make sure your current wallet is backed up! If not, backup your current wallet by going to Settings > Wallet Settings > Recovery phrase
  2. Disconnect your current wallet by going to Settings > Wallet settings > Disconnect wallet
  3. Create a new wallet as you did it before
  4. Backup the new wallet
  5. Check your new wallet public key by clicking the "Receive" button and save it
  6. Switch to your current wallet by disconnecting the new one and importing the current using a 12-word recovery phrase
  7. Transfer your balance to the new wallet using your new public key by clicking the "Send" button
  8. Switch back to your new wallet again
  9. You are done! Continue enjoying the Nodle app!

What if I received a transfer to a legacy wallet after being upgraded?

No worries, your tokens are not lost! You can re-import your legacy wallet as an account to and transfer your tokens to your new wallet. For the import, you should use your current 12-word recovery phrase, but select "Edwards" in the Advanced creation options selector.

What is a private key? Where can I find my private key?

A private key is like a password — a string of letters and numbers — that allows you to access and manage your crypto funds. It is used to sign every transaction you make on the blockchain. A human-readable form of your wallet's private key is a recovery phrase (or "seed phrase", "mnemonics"). The recovery phrase is composed of 12 secret words. You can find your recovery phrase in the Nodle app by going to Settings > Wallet settings > Recovery phrase. It is very important to write down those words on paper and keep them somewhere safe and secure as it is the only way to access your tokens.

How can I move my wallet to another device?

To move your account to another device, firstly, you need to backup your wallet on your current device. You can do it in the Nodle app by going to Settings > Wallet Settings > Recovery phrase. As a result, you will get your secret phrase consisting of 12 words that you will use to import your wallet to another device.

Once you back up your wallet, install the app on another device and use your 12-word phrase to import your wallet to another device.

How can I transfer my tokens to another Nodle wallet?

You can transfer your tokens to another Nodle wallet in the Nodle app. You need to know a public key of the recipient’s wallet to do this. Once you have it, click on the “Send” button on the wallet tab and follow the instructions. Please note that you will be charged a transaction fee for every transaction by the Polkadot blockchain. The fee amount is calculated right before you confirm the transfer, and you can check it in the app. Once you confirm the transaction, you will see it in the list of “Transfers” below your balance.

How can I recover my wallet if I lose my recovery phrase?

Your account can be recovered only with your recovery phrase. Your recovery phrase is not available to anybody except you. So, unfortunately, it is not possible to recover your account if you lose your recovery phrase.

Is it possible to run the app on multiple devices with the same wallet?

We recommend you to create a separate account for each of your devices as it will be easier to track your rewards. We also recommend using those devices in different locations to create a wider coverage and get higher rewards.
