Using Hardhat

Hardhat is a popular development framework for Solidity smart contracts. To work with a local Arthera node or with the Arthera TestNet, HardHat needs to know how to connect to the respective network. Add the following snippet in the networks section of the hardhat.config.js file. (if the networks section does not exist, you can add it).

networks: {
  arthera: {
    url: 'https://rpc.arthera.net',
    chainId: 10242,
    accounts: []
  },
  arthera-testnet: {
    url: 'https://rpc-test.arthera.net',
    chainId: 10243,
    accounts: []
  }
}

Now you can run your HardHat scripts with npx hardhat run scripts/<YOUR_SCRIPT> --network arthera-testnet
