How to Create a Cryptocurrency (Token) Without a Single Line of Code

Table of Contents

At the time of writing this article, there is an estimate of 11,000-20,000 existing tokens and cryptocurrencies. The vast majority of these are tokens, and only a few are considered actual cryptocurrencies.

Here, we will not delve into the differences between these two terms. But we will try to explain how such a large number of assets could have emerged.

Is each token a separate blockchain?

Not always. Most tokens are deployed on the Ethereum blockchain. According to Nomics, there are more than 12,500 tokens on the Ethereum network. But of this number, only just over 4,160 have any volume. In second place is Binance Smart Chain with more than 8700 tokens.

The choice of blockchain is a personal matter for the developer. Networks differ in both commission costs and community size.

It is important to understand that a token created on one network such as ETH will not work on another such as BSC. The only way to “transfer” a token is to use the so-called “bridges”.

Create your own cryptocurrency: What do you need?

  1. Your time (no more than one hour)
  2. Browser extension with your MetaMask Wallet, Coinbase or Trust Wallet
  3. Balance in the Wallet (if you want to create a free trial token you will have to apply for trial ETH)

How can I create a cryptocurrency or token?

Ideally, of course, you should understand the basic mechanics of the token you want to create. Also, have an idea of what that part of the code is responsible for. But let’s say you don’t want to learn the basics, and you can’t wait to create something as quickly as possible at the lowest cost.

Since the blockchain market is developing, enthusiasts have launched a bunch of platforms to create tokens in a very simple way.

This means that there are several sites that are ready to take care of the entire technical component for you.

Here are some of them:

  • cointool.app
  • vittominacori.github.io
  • createmytoken.com
  • guard.co

How to mine cryptocurrencies: step-by-step guide in our blog post.

We recommend Cointool.app

We recommend you to use cointool.app as it is the market leader. However, all the web portals mentioned above are similar and the operation for creating tokens is almost the same. There is a field for the token name, ticker, coin volume and everything you need to create the cryptocurrency.

Before you start creating a token, you need to synchronize your wallet with the chosen portal.

Let’s assume that you have already installed it in your browser. The wallet will be necessary for the site to independently create a smart contract, through which it will issue tokens. This service is paid if you want to create a real token. If you just want to try it for free, then read on.

To sync with cointool.app, click the button in the top right corner “Connect wallet”. Your wallet window will close. Accept the terms and connect. Next, we start choosing a network for the token.

Choosing a network and the cost of creating a cryptocurrency (token)

The blue section of the form in cointool.app is the blockchain network/scaling protocol selection. You already know the difference between them in the section

“Is each token a separate blockchain?” If you missed it, we recommend you read it again.

At the time of writing this article, creating a real token through cointool.app will cost you some real cash. More specifically, 0.1 ETH (~$400).

What is the difference between a real token and a trial token? Once a real token is created, you can list it on exchanges and trade with it. It is impossible to be traded with a proof token.

The process of creating a real token and a test token is the same. Even in a test scenario, you have to pay a fee. (with free tokens). In our case, we will look at a test case for creating an ERC20 token on the Ethereum testnet called Kovan.

Create your own cryptocurrency: Connecting the wallet to the network

By default, MetaMask connects to the Mainnet and displays the corresponding balance. You have to switch to the Kovan test network. Of course, you can also choose other networks: Ropsten, Rinkeby and Goerli.

To connect to the test network, open MetaMask > click the “Ethereum Mainnet” button above > click “Kovan Test Network” in the drop-down menu.

If you had cryptocurrencies in MetaMask, now your balance has been reset. It’s OK: your wallet just connected to a different network. You can switch back to the old network using the method described above and the balance will be restored again.

Once connected to Kovan , the cointool.app site should reload and show the “Eth Kovan” network selected in the top right. If this does not happen, make sure your wallet is connected.

So, we are connected to the test network, when are we going to create the token already? Soon.

The last point remains – getting free tokens. For this, you can use the token tap.

Here are some services that give free tokens for trial use:

  • faucet.metamask.io
  • faucet.egorfine.com.

Choose whichever. Once on the website, paste your public address. You can get it by opening MetaMask and clicking on the “Account 1” column.

Once you have submitted a request to receive free tokens, you will have to wait. The trial ETHs will arrive in your wallet in 5-10 minutes.

Attention. If you start sending ETH requests several times, then your wallet will be blacklisted for 24 hours. Just send your request and wait for  5-10 minutes.

Setting up the cryptocurrency (token)

Once we receive the test ETH, we proceed to the creation of the token itself.

The form in cointool.app contains the following fields:

  • Token Name (example: Bitcoin, Ethereum, Dogecoin).
  • Symbol – the token ticker (e.g. BTC, ETH, DOGE)
  • Initial bid – the initial maximum amount of tokens
  • Decimals – system of calculations (the minimum that your token can be divided. For example, BTC is divided by 8 decimal parts, and ETH by 18)
  • Burn – burn tokens
  • Mint – the ability to create additional tokens (the amount will be added to the initial supply)
  • Pause – the ability to stop all operations with the token (function in case a critical vulnerability is detected)
  • Deflation – a fee is charged for each transaction with a token, which is then burned
  • Super deflation – accelerated mode of the deflation function.

It is optional whether to fill in all fields. In our case, we call the test token Cronuts Digital Coin, and the ticker CDC. The rest of the settings we will leave at their default values.

Paying for the creation of the smart contract

Once you have configured all the settings > scroll down and click the “Create Token” button.

A window will open in your wallet with a request to send ETH to create a contract with your token.

In our case, it took 0.00001 ETH token.

Finding out the details of the smart contract

First we need to find out the address of the smart contract that created the tokens.

To do this, go to the “Activity” tab and look for a transaction called “Contract Deployment” for which 0.00001 ETH was paid.

Click on the transaction, and in the details click on “View in block explorer”.

As seen below, an etherscan.io window will open for you.

This describes all the details of creating a smart contract for your token.

We find the line where it says “Contract” and the address of the contract itself. Copy this address.

Next, we open the MetaMask main page > at the bottom, click on “Import tokens” > in the “Token contract address” field and paste the copied address.

The wallet should automatically pick up the imported smart contract data, including the token ticker and calculation system. Click “Add custom token”.

And now, the generated tokens (in our case, CDC) appear in our Wallet.

The appearance of the token (logo, description, links to social networks) can also be specified in the “Create token” > “Create token view” section of cointool.app.

Now that you know how to create a test cryptocurrency (token), you can create a real token. But you will need to pay in real ETH.
