Setup

Contract

• Add .env file corresponding to .env.sample in faucet-contract folder

• Add the network in which the contract is to be deployed

Sample Network config

mainnet: {
      network_id: '1',
      provider: () => {
        const truffleProvider = new TruffleProvider(
          'https://api.s0.t.hmny.io/',
          { menmonic: process.env.MAINNET_MNEMONIC },
          { shardID: 0, chainId: 1 },
          { gasLimit: gasLimit, gasPrice: gasPrice},
        );
        const newAcc = truffleProvider.addByPrivateKey(process.env.MAINNET_PRIVATE_KEY);
        truffleProvider.setSigner(newAcc);
        return truffleProvider;
      },
    }

Enter the required environment variables in the .env file. For the above config it would be MAINNET_MNEMONIC and MAINNET_PRIVATE_KEY.
