Connecting a Nano S hardware wallet to TecraCoin

The main idea behind the device is to be the easiest way to secure your TecraCoin and other cryptocurrencies offline. In the case of Ledger, the devices make use of something called a ‘secure element’. This helps make them resistant to physical attacks and allows for a more secure cold offline storage of your TecraCoins.

This also protects the private keys from malware and means improved security over other software wallets. The benefits of using a hardware wallet are: 

  • Keeps your crypto offline and out of reach of hackers.
  • Gets your crypto off exchanges and into your control.


1. Connecting Metamask to TecraCoin blockchain:

In order to use nano S ledger wallet to secure Tecracoin account, it is required first to connect TecraCoin blockchain to MetaMask.

  • Open MetaMask wallet, go to “parameter” then “network”
  • click on “add a network”
  • Fill the form: 
    - Name of the Network: “TecraCoin” 
    - RPC’s RPC: “https://tsc-01.tecra.space”
    - Chain Id: “20531812”
    - Symbol of the currency: “TCR”
    - URL of the block explorer: “https://explorer.tecra.space” for connecting TestNet
  • Open MetaMask wallet, go to “parameter” then “network”
  • click on “add a network”
  • Fill the form: 
    - Name of the Network: “TecraCoin Testnet”
    - RPC’s RPC: “https://tsc-02.testnet.tecra.space”
    - Chain Id: “20531811”
