Deploy Your Smart Contract Directly from Truffle with Infura

It is often painful to develop on Remix with copying/pasting code on Open-zeppelin repository and scroll down the whole code without any gizmos included in the editor.

Well, not anymore. I found a way to do all that within the Truffle framework.

1. Get Metamask

Trust me. It is really comfortable to have this without downloading full node of ethereum.

2. Get infura API Key.

infura is secret weapon to ethereum infrastructure.

Here’s what ConsenSys media says:

Many of the blockchain space’s most remarkable projects — Metamask,CryptoKitties, UJO, Radar Relay, Cipher Browser, uPort — utilize Infura’s APIs to connect their applications to the Ethereum network.

This includes signing to transaction for creating contract on metamask, which is what we are going to do.

3. `truffle init` then install truffle-hdwallet-provider.

Initialize truffle project on a folder and install truffle-HDwallet package with npm.

npm install --save truffle-hdwallet-provider

4. Set Environment Variable with dotenv

‘dotenv’ package opens .env file and stores its key and value to process.env variable.

First install dotenv on the project

# with npm

npm install --save dotenv

# or with Yarn

yarn add dotenv

Then setup environment variable:

MNENOMIC = // Your metamask's recovery words
INFURA_API_KEY = // Your Infura API Key after its registration

5. Edit truffle.js(truffle-config.js on Windows) with this file

I hope to apply this in truffle-box in near future:

6. Deploy to the desired network

For example, if the contract is deployed on Ropsten testnet:

truffle migrate --network ropsten

Voila! the contract should be deployed and show logs like this:

Using network 'ropsten'.

Congratulations if you deployed your smart contract successfully! Next, I will go through how to deploy website on IPFS with Infura.
