Unable to deploy on truffle ropsten

Support
1

Hello Zeppelin folks,

I am working on an art project for which I am writing an ERC721 smart contract. I am using infura endpoint and openzeppelin-solidity: "^2.3.0" framework to speed up the development.

I am not able to deploy on ropsten. truffle deploy --network ropsten-infura --reset does not do anything after

Compiling your contracts...
===========================
> Everything is up to date, there is nothing to compile.

My truffle-config.js looks like the following:

require('dotenv').config();
const HDWalletProvider = require('truffle-hdwallet-provider');
// MNEMONIC_PHRASE and INFURA_KEY are mentioned in .env file
const mnemonic = process.env.MNEMONIC_PHRASE;
const infuraKey = process.env.INFURA_KEY;

module.exports = {
    networks: {
        development: {
            host: "127.0.0.1",
            port: 8545,
            network_id: "*",
        },
    "ropsten-infura": {
        provider: () => new HDWalletProvider(mnemonic, 'https://ropsten.infura.io/v3/' + infuraKey, 0),
        network_id: 3,
        gas: 5500000,
        gasPrice: 100000000000,
        timeoutBlocks: 200,
    },
    mocha: {}
    compilers: {
        solc: {
            version: "0.5.2",
        }
    }
}

I feels like problem lies in the truffle-config.js file. I am just not able to figure it out. This is my first deployment using truffle. I have deployed before but it was a plane smart contract and i used parity interface.

Help is very appreciated as the deadline to finish this near.

Hi @shubhamy2015

Do you have a migration file in the migrations directory to deploy your ERC721?

e.g. 2_deploy_token.js

var MyContract = artifacts.require("MyContract");

module.exports = function(deployer) {
  // deployment steps
  deployer.deploy(MyContract);
};

See Truffle documentation on running migrations:

Yes.

I have a file 2_erc721_migration.js in migrations folder.

const ToTERC721 = artifacts.require("ToTContract");

module.exports = function(deployer) {
  deployer.deploy(ToTERC721);
};

ToTERC721.sol is there in the contracts folder.

pragma solidity >=0.4.21 <0.6.0;

import "../node_modules/openzeppelin-solidity/contracts/token/ERC721/ERC721.sol";
import "../node_modules/openzeppelin-solidity/contracts/math/SafeMath.sol";
import "../node_modules/openzeppelin-solidity/contracts/utils/Address.sol";
import "../node_modules/openzeppelin-solidity/contracts/introspection/ERC165.sol";

/**
 * @title VoV Non-Fungible Token implementation
 * @dev see https://eips.ethereum.org/EIPS/eip-721
 */
contract ToTContract is ERC721 {
...
...
...
...
}

I am successfully able to deploy on Ganache and test it there as well.

Hi @shubhamy2015 is your project opensource so that I can attempt to reproduce?

Otherwise I will attempt to replicate myself with the code that you have provided so far.

6

I am guessing the INFURA_KEY is technically the PROJECT ID from Infura Dashboard. Am I correct?

Also please check the screenshot. I am leaving those settings untouched. Is that OK too?

No, not yet. It’s university project and we have no license yet.

8

Yes @shubhamy2015 you use the PROJECT ID as your INFURA_KEY.

It should be fine to leave the Infura security settings as is.

9

Please provide your email ID. I will share it with you. At this stage, the solution is more important. Are you on any chat medium? Slack, Discord or telegram? It will make things faster.

You can send me a direct message on the forum and I can have a look.

Hi @shubhamy2015

I deployed the following to Ropsten ok using truffle deploy --network ropsten-infura --reset

I put my code on GitHub too. (I added a mint)

I am using truffle version Truffle v5.0.2 (core: 5.0.2)

I had to add some commas and braces to your truffle-config.js (assume you cut it down).

I suspect your .env file might be the issue

.env

INFURA_KEY="ENTER YOUR INFURA PROJECT ID HERE"
MNEMONIC_PHRASE="ENTER YOUR 12 WORD SEED PHRASE HERE"

Smart Contract

pragma solidity >=0.4.21 <0.6.0;

contract ToTContract is ERC721 {
    constructor() public {
        _mint(msg.sender, 1);
    }
}

2_deploy_token.js

const ToTERC721 = artifacts.require("ToTContract");

module.exports = function(deployer) {
  deployer.deploy(ToTERC721);
};

// MNEMONIC_PHRASE and INFURA_KEY are mentioned in .env file
const mnemonic = process.env.MNEMONIC_PHRASE;
const infuraKey = process.env.INFURA_KEY;

module.exports = {
    networks: {
        development: {
            host: "127.0.0.1",

        provider: () => new HDWalletProvider(mnemonic, 'https://ropsten.infura.io/v3/' + infuraKey, 0),

For future readers the deployment issue was not with @shubhamy2015 code but was a firewall issue and the deployment worked on another computer.
