Finding your subnet provider
Subnet providers help with the setup of your Fexr wallet. While you hold the private keys to your wallet, you will need to find a subnet provider to help you with the hot wallet which interact with outside network (e.g. exchanges, other wallets, etc.).
How do you find a subnet provider?
Subnet providers are listed primarily in Fexr app. They can be found in the “Subnet Providers” section of the app. You can also find them on the subnets.fexr.club
How do you know if they are trustworthy?
At Fexr, you dont have to trust any subnet provider to keep your secrets. All your private details connected to your wallet is stored only on your device. You can verify this by checking the source code of the communicator tool used by the subnet providers. You can also verify the source code of the subnet provider by checking their github repository.
Creating wallet with a subnet provider
When you create as new wallet, keys are generated within your device but a hot wallet (full node without access to secret key) is needed to verify incoming token details and trigger smart contracts when the users are offline.
What if a subnet provider barred you from their network?
Fexr work with only those protocols which allows users to manage their
