The process is super easy, and the code we provided though working is just a minimal example. You can build many great things on top of what we did today, and I hope I can hear from you all the great projects that you build using the power of blockchain. Today I want to share with you what was my first project, the creation, and deployment of an ERC20 token. You don’t even need to be a programmer to create your own cryptocurrency. Several existing blockchain platforms let you to make your own currency – as a community coin, a joke, or for any other reason. With a section called “Deployed Contracts” and right bellow our Token contract information.
After you do that, your account will automatically populate the “Account” filed below with the account number and your current balance in ether. With everything looking good we just need to deploy the code, head now to the 4th tab on the menu “Deploy & Run Transactions”. The first section we see on the left is our contextual menu, and in the right section we see the welcome screen. As we are by default on the file explorer the contextual menu shows all the files and folders that are available. Last but not least, you will need to code which will run our own cryptocurrency.
However, it will also give you more freedom and control over your coin, ledger, and its features. You may also choose to fork one of the already existing open-source blockchain projects launch your own cryptocurrency by changing some of its rules to fit your purpose. Today we learned how to build and deploy your own cryptocurrency by following the ERC20 interface and utilizing Remix and MetaMask.
One important data on that screen is the address where the code got deploy, please copy that using the copy icon on the right, highlighted in the picture above. Lastly, we need to specify we want to deploy, make sure you select your contract from the “Contract” dropdown field. The good people from Ethereum provide us with an IDE that is fully capable of handling the full process, from editing the files, building, and deploying, among many other things. If we are on the main network of Ethereum, we would have to use actual money, like EUR or USD, to buy Ethereum first, and then create our token. However, the beauty of the test network is that we can get free Ethereum using applications called faucets. Now, this is just fake ETH, so we can’t sell them to anyone or anything, but it’s good enough to deploy our test tokens.
One of the benefits of using a test network is that, not only we can submit any code we want and test it out, but also we can do it free of charge. Every time a new token is created, it is necessary to register a transaction on the Ethereum network it is running. And this transaction will come with a GAS fee which we will need to pay with Ethereum from the network. Cryptogeek.info needs to review the security of your connection before proceeding.

I’ve already prepared for you a sample code that will implement the ERC20 specification and will give you basic cryptocurrency functionality. Growing demand for blockchain-based services has sparked the growth of firms and services that create and maintain distributed ledgers for others. Such businesses are called “blockchain-as-a-service ” companies. You can find most open-source codes of existing blockchains on GitHub.
From Zero to Blockchain in Python – Part 1 Building together a blockchain application in Python, step by step we will start with the basics until we have a fully functional blockchain. You need to find and replace all occurrences with each one of them. There are a few https://xcritical.com/ things that we need to prepare in advance before creating our token, and those are described below. Of course, the latter approach is much more complicated and requires in-depth training, code/programming skills, and a fundamental understanding of the technology.
After the process is complete you will receive a confirmation on the screen with the information of your deployed contract, including the address where the code got saved. The deployment process may take anywhere from a few minutes to up to who knows how many minutes depending on the status of the network at that time. Usually, I found that Ropsten will take 2 to 3 minutes, and the maximum wait time I had was 10 minutes. You will need to create a new file here by clicking on the “+” button near the “browser” folder on the left panel. There are already a few files in there now, but you can ignore them. You can name the file to your likes, it’s not relevant for the process.
Up to this point, our token already exists in the Ethereum network and can be used to transact, however, how do you access your tokens? Turns out that MetaMask as well as other walltes can already operate with your token as it follows a specification called ERC20. The first line of code is simply required to run any solidity program, but the rest is where it gets interesting. So download MetaMask and set it up on your browser creating an account on the Ropsten Test Network.
And with that code open MetaMask, and click on “Add Token”. This will pop up a screen with 2 tabs, switch to the second tab called “Custom Token” and paste the address you copied in the contract address field. This will automatically populate the token symbol and decimals fields. If you wonder ‘’how to create my own cryptocurrency from scratch’’, it includes building a distributed ledger which demands a lot of work.
After obtaining a code, you may also want to make changes to it to make sure it allows you to fulfill the purpose of your project. If you don’t want to be dependent on any of these platforms, or they don’t offer the functionality you need, you can try to build your own blockchain from scratch. Build an Amazing Web Frontend Portfolio with these Resources Find out interesting projects and resources to build and showcase as your frontend portfolio. If your project is serious, prepare for more challenges ahead. Maintaining a successful project is way harder than launching it. Maintenance may require further coding, teamwork, a network of computers, and investments in sales and marketing if you want your coin to become known and used.
This process is super easy and guided, so I won’t get into many details. Though, you should have in mind that forking a project doesn’t copy its entire ecosystem and stakeholders along with the code. You will have to figure out the incentives and create a functioning ecosystem to make it all work. Most new cryptocurrencies are basically worthless, especially if there is no one else but you to verify the transactions. The open-source nature of the cryptoverse makes it a relatively easy task.
You probably know Ethereum and its network, however, did you know that there are multiple instances of Ethereum running? Most people are familiar with the main Ethereum network, where all the transactions are running, and where all exchanges operate . But there’s more to it, there are alternative networks running the same code as the main instance for example for testing purposes. An example of this is the “Ropsten Test Network” which we will be using today to deploy our code. In this article, we will provide the code for a simple cryptocurrency as well as all the steps that are necessary to get your token up and running on the Ethereum network.
