OpenZeppelin CLI Testnet and Mainnet configuration

The following shows the configuration for accessing testnet and mainnet with OpenZeppelin CLI. See Connecting to Public Test Networks for details.

Similar configuration can be used for Truffle.


const { projectId, mnemonic } = require('./secrets.json');
const HDWalletProvider = require('@truffle/hdwallet-provider');

module.exports = {
  networks: {
    development: {
      protocol: 'http',
      host: 'localhost',
      port: 8545,
      gas: 5000000,
      gasPrice: 5e9,
      networkId: '*',
    rinkeby: {
      provider: () => new HDWalletProvider(
        mnemonic, `${projectId}`
      networkId: 4,
      gasPrice: 10e9
    mainnet: {
      provider: () => new HDWalletProvider(
        mnemonic, `${projectId}`
      networkId: 1,
      gasPrice: 30e9  // check

Mnemonics need to be kept secure. Be cautious of value and access controlled by this mnemonic.

I get “unexpected identifier” when I try to run with these settings. Checked the ProjectID and it seems to be correct.

I assume that you have a malformed network.js.

Can you share your network.js? Please don’t include any secrets (mnemonic, Infura Project ID).

Hi Andrew,

Thanks, I got it to work now, happy about that.

  1. These configuration files are more clear and easier to get started with than the ones in the link you sent previously
  2. I also had an issue on my side, I was working on a server using SSH so I got some formatting issues which were causing the error. I will try to update my setup so it won’t happen again.

See you next time.

Hi @TivoliLocust,

I’m glad you were able to resolve.

I created these using the Learn guide, though I agree it can be easier just to copy and paste the whole contents of the file.
