Over the past few years since the launch of the Ethereum network and other blockchains that can create tokens, initial coin offerings (ICOs) have been all the rage as all of these token projects have raised billions of dollars in ether, bitcoin, and other cryptocurrencies. A great majority of the ICOs today are ‘ERC-20 tokens’ created by the Ethereum Virtual Machine (EVM) with no more than a few hundred lines of code. Unfortunately, there’s a big misconception that a bunch of nerdy geniuses created these blockchain-based tokens, and today we’re going to show you just how easy it is to create an ERC-20 token — In less than thirty minutes.

Posternut (PNT): The ERC-20 Token Created in Less Than 30 Minutes

Today we decided to create a contract using the programming language Solidity, in order to create a custom token using the Ethereum network. We want to demonstrate just how easy it is for anyone with very little coding knowledge to launch a coin. There are lots of ICOs out there in the crypto-space and a great majority of them are ERC-20s derived from the public Ethereum blockchain. Essentially an ERC-20 token is a contract written in Solidity that sets the parameters of the coins attributes, like where the tokens are stored, the token’s name, ticker symbol, supply, and more.

We used this code here found in the walkthrough written by Moritz Neto and the code was developed by an Ethereum developer called ‘BokkyPooBah.’

The Necessary Requirements

Finding out how to create a token only takes a minute with a quick Google search on the subject. We followed a short walkthrough written by Moritz Neto, and watched a quick video filmed by the Youtuber Ivan on Tech. Both instructions detailed the creation of an ERC-20 token that can be done in less than 20 minutes, and we created a token called ‘Posternut (PTN) in 25 minutes. In light of our first time creating a Solidity contract, we used ETH testnet tokens on the Ropsten Network so no real funds were lost.

Using a text editor to modify the copied Solidity code is helpful as you can find the lines of code that need to be updated more easily. The max supply, token name, address output, and token symbol are just some of the things you can change within the code.

Next, we decided to download the Metamask Chrome extension Ether wallet, a fairly smooth platform but still in beta. Other wallets can be used to create a token contract as well, like Mist and the My Ethereum Wallet (MEW) platform. You are also going to need some testnet ETH for the ‘gas’ (network fee) to create the contract on the Ropsten Network, and there are a bunch of Ropsten faucets that dispense testnet ETH. We stocked up on some coins and then found a contract which we got in Moritz Neto’s guide, but there are all types of solidity contracts that can be re-written. Basically, we left this page open in the browser to copy and paste the Solidity contract, and all that is needed next is some slight modifications.

Using Remix to set the parameters of the code, double check it and deploy on the Ethereum Ropsten Network. This entire process can also be done on the ETH mainnet with real funds.

Then we went to a website called which is used to launch the contract. This process can also be processed on the aforementioned wallets above as well, but we used the Remix Solidity IDE platform. After copying a token contract you need to paste the code into the Remix platform and edit a few parameters. This is when you want to choose the tokens name, the token’s symbol, the max supply, and the Ethereum address to deposit the tokens. After all of that is chosen and changed within the copy and pasted code, the next option is to ‘run’ the codebase you edited. If there are any warnings that are ‘critical’ the Remix platform will tell you something is wrong. In the ‘run’ section choose ‘Injected Web (Ropsten)’ and the name of your contract.

Deploying the contract and confirming it using Remix and Metamask. After this step simply wait for an error or wait for the transaction to confirm and when it does your token will be complete.

From here the Metamask address is also tethered to our account and we simply pressed deploy. If something is wrong with the contract then it will display warnings in yellow or red and you may need to fix these issues before deploying the code to the Ropsten Network. After pressing ‘deploy,’ the transaction will be sent across the network. As soon as the transaction confirms the contract should be complete as long as there were no errors.

After Posternut (PTN) token was created we then sent the newly minted coins to another Metamask wallet address.

Things Needed to Deploy a Token Contract on the ETH Network in Thirty Minutes:

  • An Ethereum wallet. (Mist, MEW, Metamask)
  • Testnet Ethereum or real ETH can be used for gas.
  • A Solidity token contract.
  • A platform to deploy the contract either on testnet (Ropsten, Rinkby) or mainnet. (Remix, MEW, Mist)

The Simplicity of Launching an ICO

The name of our token is called ‘Posternut (PNT)’ and there are 100Mn tokens now in existence on the Ropsten network. Creating the token took only 25 minutes and the same thing can be done on the main Ethereum network with less than $20 USD worth of real mainnet ETH for gas. Most of the time-consuming parts of the process is basically studying the directions on how to create an ERC-20 token, and following each step. After creating the Posternut tokens we decided to send the 100Mn PTN to another address which was sent with no issues.

The Posternut (PTN) token was created on May 10, 2018, on the Ethereum Ropsten Network by Jamie Redman.

As we stated above, it doesn’t take a genius to build an ERC-20 contract and now that you have seen the different Solidity contracts that make this process work, you can also see if an ICO project used this same method. Simply look at the contract code to see if it resembles something copied from another project, as you’d be surprised to find quite a bit of them. After creating the Posternut tokens there are only a few other things needed to launch an ICO. Observers will find that all a team needs to push a project, is a website, and a white paper. We all know that these ICOs raise a lot of money as token sales have raised over $5.6Bn in 2017 alone, and continue to raise funds this year. If all it takes is a website, 25 minutes of coding, and a white paper this may be why over 46 percent of ICOs fail.

Before Investing in Token Sales, Do Yourself a Favor and Research These Projects

So before investing in an ICO do some research on the project and make sure it is not some ‘fly by night’ guy who coded a coin in less than thirty minutes. The fact is just because a person(s) can build an ERC-20 token doesn’t mean the project is worthy, and investors should diligently research ICO teams and the tokens they are selling. Otherwise, you could be purchasing a quickly made coin, and buying into a word salad white paper written to make you believe Posternut (PTN) tokens are the future of decentralization.
