The network is the official Binance Testnet. Let’s connect MetaMask to the Testnet by adding yet another Network. Luckily for us, the testnet has faucets that allow us to get free test Ethereum. Remember this if you push a smart contract to the real Binance smart chain, it will draw your money.īut I don’t to pay money to deploy to test! - Cheap developer The reason is as I’ve repeated many times now, it costs to deploy a smart contract. Truffle migrate - Failure due to insufficient gas If you are using a new MetaMask account as I have done in this series, you will see the following. Try running the command to see what happens. Remember that to push to test and production you will have to pay gas. The beautiful part here is, to deploy to Test or production we can use the same procedure, just add a - network flag to the command and specify what network to deploy to. Remember how we ran truffle migrate to deploy to Ganache? Using it will allow us to also have a Development environment (Ganache), Test (Testnet), Production (real Binance smart chain). The Testnet is a complete replica of the real Production network, so it is a great way to try everything out. Now the reason to deploy to TestNet is that it will work like a test to see that the Smart contract works as expected. We will begin deploying it to TestNet to see how easy it is to deploy. If you have pasted your mnemonic into the .secret file It’s time to try deploying the smart contract. But if you’ve forgotten it you can view it by following this link. You should have gotten the seed phrase when you created your account in MetaMask. This is a list of words that are used to access your wallet. This file should contain only one thing, your mnemonic. exports = Truffle - Config that allows us to deploy to all three networksīefore this will work you need to notice that we are reading a file named. npm install that we need to uncomment the module.exports fields and add the following three networks.Ĭonst HDWalletProvider = require ( ) const fs = require ( 'fs' ) const mnemonic = fs. We will also need to use the truffle/hdwallet-provider which you have to download. The latest deployment information which the correct seeds to the networks can be found here. We will open up three networks so that we can deploy them to all three networks. We will begin by updating the Truffle configuration in our truffle-config.js. You can find the full code used from the previous parts here. Fourth and last article in which we learn how to deploy our Smart contract to the real networks Using a Smart Contract In An Web Application - Third article of the series in which we learn how to connect to the Blockchain via an Web application using MetaMask In this article, we will look at how to deploy the Smart Contract to the Binance testnet instead of our local Ganache instance.īuilding a Decentralized Application With BEP-20 In Solidity - This article will help you understand the basics of SolidityĬreating a Inheritable Staking contract in Solidity - Second article in which we cover more advanced Solidity items and implement Staking and Rewarding This is the fourth and last article in a series in where we are building a DApp from scratch with a custom-built BEP-20 Smart contract.
