In this tutorial we go into more depth and teach you the code to deploy your own Ethereum ERC token. We talked already how Smart contracts opened a whole new world for developers to create and innovate.

However, these developers needed a way to finance their projects. In ICOs were booming — countless projects appeared every day with wild promises of what they wanted to achieve, and investors lapped them up.

Tokens are essentially smart contracts which live on the Ethereum Blockchain, they can have may uses and purposes.

A token is not limited to one particular role. It can fulfill a lot of roles in its native ecosystem.

ERC is a technical standard used for smart contracts on the Ethereum blockchain for implementing tokens. The majority of tokens issued on the Ethereum blockchain are ERC compliant.

To keep it simple, ERC is a guide of rules and regulations that will help create a blueprint for Ethereum-based smart contracts to create their tokens.

So basically a token is just a contract that keeps track of who owns how much of that token, and some functions so those users can transfer their tokens to other addresses.

Since all ERC tokens share the same set of functions with the same names, they can all be interacted with in the same ways.

That way more tokens can easily be added to your app in the future without needing to be custom coded. You could simply plug in the new token contract address, and boom, your app has another token it can use.

One example of this would be an exchange. When an exchange adds a new ERC token, really it just needs to add another smart contract it talks to.

Remix is online tool that allows you to write Solidity smart contract, then deploy it and run it. ERC tokens follow a list of rules so that they can be shared, exchanged for other tokens, or transferred to a crypto-wallet.

It is common practice to define these rules in the interface. Luckily, one can inherit Smart Contracts in Solidity programming language.

In Solidity, inheritance is pretty similar to classic oriented object programming languages. You also need to know that Solidity supports multiple inheritance by copying code including polymorphism.

All function calls are virtual, which means that the most derived function is called, except when the contract name is explicitly given.

When a contract inherits from multiple contracts, only a single contract is created on the blockchain, and the code from all the base contracts is copied into the created contract.

We will define them as 6 functions and write it in interface. Even though it is not necessary to name your tokens, it is still important to give it an identity.

Up next we have symbols. We simply cannot understate their importance. A catchy symbol helps with better branding. Finally, we have the divisibility which will help us determine the lowest possible value of the token.

A divisibility of 0 will mean that the lowest value of the token is 1. A divisibility of 2, on the other hand, means its lowest value will be 0.

The maximum number of decimal places allowed is Our token also needs to have an initial supply, and some record of all balances.

We can store that information in array. In constructor we will initialize our contract with initial supply tokens to the creator of the contract that is msg.

Add these lines to our code and we will discuss purpose of all of them. Solidity is a statically typed language, which means that the type of each variable state and local needs to be specified at compile-time.

Solidity provides several elementary types which can be combined to form complex types. Integers can be int or uint : Signed and unsigned integers of various sizes.

If you are familiar with Computer Science theory or you know the difference between signed and unsigned integers in C language, everything is absolutely the same in Solidity.

Signed on the other hand can be both negative and positive, but we will use only units in our contract. Keywords uint8 to uint in steps of 8 unsigned of 8 up to bits and int8 to int We talked that we will store balances in some kind of array.

Well, the better solution is to use hash tables, or in Solidity mappings. In that case, the contract that is creating the call would be the msg.

The similarity ends here, though: The key data is not actually stored in a mapping, only its keccak hash used to look up the value.

Mappings are only allowed for state variables or as storage reference types in internal functions. It is possible to mark mappings public and have Solidity create a getter.

The blockchain is a list of blocks which are fundamentally lists of transactions. Each transaction has an attached receipt which contains zero or more log entries.

Log entries represent the result of events having fired from a smart contract. In the Solidity source code, to define an event, you mark it thus by preceding it with the event keyword similar in usage to the function keyword.

Euro depend on the respective exchange rate of ETH. The more computers in the network confirm the transaction , the more secure in the sense that it took place it can be considered.

In comparison to offline processes - for example a notary who confirms a transaction - this results in the potential to significantly reduce costs and time expenditure for such sensitive transactions on the one hand, while on the other hand aspects of audit security and transparency are increased.

A blockchain is an audit-proof decentralized digital general ledger of transactions that can record not only financial transactions, but virtually any type of transaction.

The easiest way to describe Ethereum is as an open software platform based on blockchain technology that allows developers to create and deploy distributed applications.

Like Bitcoin , Ethereum is a distributed public blockchain network. Although there are some significant technical differences between the two, the most important difference is that Bitcoin and Ethereum differ significantly in purpose and capability.

Bitcoin offers a specialized application of blockchain technology , a peer-to-peer e-payment system that enables online Bitcoin payments.

So while the Bitcoin blockchain is used to track the ownership of the digital currency Bitcoins , the Ethereum blockchain focuses on the execution of program codes of any distributed application.

In the Ethereum blockchain , so-called Ether ETH , a crypto token that drives the network, are earned for providing computing power "mining".

In addition to its role as a tradable crypto currency , Ether is also used by application developers to pay transaction fees and services in the Ethereum network.

As described at the beginning of this article, the Ethereum blockchain enables the use of tokens which can be bought, sold and traded by users.

These should not be confused with Ether ETH , which is "only" the natural currency of the Ethereum Blockchain infrastructure as described above.

Tokens are digital assets or programs based on the blockchain. These tokens serve the purpose of attributing a value to them , such as promissory notes, profit participation rights, services or real objects.

Hence tokens are generally not to be confused with crypto currencies for example Bitcoin or Ether. Tokens are basically so-called "Smart Contracts" , which in the case of ERC20 are executed on the Ethereum block chain.

ERC20 is therefore a standard protocol that defines the properties and functionality of an Ethereum blockchain token. ERC20 is a standard protocol that defines the properties and functionality of an Ethereum blockchain token.

A token in general is basically simply a digital representation of potentially anything. For example, a token can represent a stock, a bond, an option, or a property etc.

A token can also represent access rights to a blockchain or blockchain app , and tokens can also be used to automate "friction points" in various industries.

Utility tokens , are tokens that have a specific "use" on the blockchain or an app based on that. Utility tokens are also called "app coins" because they are explicitly designed for a certain app or blockchain.

Security tokens , on the other hand, represent investments , such as securities such as shares, bonds, funds etc.

Thus, securities of companies, fund houses or real estate funds , which are issued via the blockchain , are referred to as security tokens.

As is the case with traditional "securities", security tokens thus represent profit participation, interest income or give voting rights or generate profits for the holders of those tokens.

While utility tokens are earmarked and explicitly designed for a specific app or blockchain, security tokens represent investments and are therefore subject to various regulations and legal frameworks.

The creation of your own token is simple - but its emission can be potentially associated with legal implications. We therefore strongly advise against creating a token for fun-only and without prior legal advice.

MetaMask thus makes it possible to manage identities on different websites and sign blockchain transactions. The following is an exemplary use at your own risk!

Smart-Contract , which can be adapted as described below in the next step to create your own ERC20 token. Source: Token Factory and maxnachamkin.

Keywords uint8 to uint in steps of 8 unsigned of 8 up to bits and int8 to int We talked that we will store balances in some kind of array.

Well, the better solution is to use hash tables, or in Solidity mappings. In that case, the contract that is creating the call would be the msg.

Mappings are only allowed for state variables or as storage reference types in internal functions. It is possible to mark mappings public and have Solidity create a getter.

The blockchain is a list of blocks which are fundamentally lists of transactions. Each transaction has an attached receipt which contains zero or more log entries.

Log entries represent the result of events having fired from a smart contract. In the Solidity source code, to define an event, you mark it thus by preceding it with the event keyword similar in usage to the function keyword.

I doubt there is a standard wording for it. You may fire events from any function using the emit keyword. To do that, we need to write code for all of our six mandatory functions.

Identifies the total number of ERC tokens created. The purpose of this method is to determine the total number of tokens floating around the ecosystem.

Returns the number of tokens that a particular address, in this case, the contract owner, has in their account.

In order to carry out a transaction one of the most important data that the contract should know is the balance of the user.

After all, the user should have the minimum amount of tokens required to do the transaction. This is why, the ERC contract also includes the allowance function.

The approve function also checks the transaction against the total supply of tokens to make sure that there are none missing or extra.

Arithmetic operations in Solidity wrap on overflow. This can easily result in bugs, because programmers usually assume that an overflow raises an error, which is the standard behavior in high level programming languages.

So, now that all the checking has been done and the contract knows that the user has the required amount of tokens needed to fulfill the transaction, the contract owner can send them tokens using the transfer function.

This function lets the owner of the contract send a given amount of the token to another address just like a conventional cryptocurrency transaction.

We all have to pay some amount of money every month like clockwork. It could be your rent, the bills, etc.

You can always set up an automatic payment system with your banks to take care of these payments. It helps you automate payment transfers to a specific account.

Metamask is extension that allows you to run Ethereum dApps right in your browser without running a full Ethereum node. When the extension is installed, click on the icon in the upper right corner of your browser to get started creating a wallet.

You will see a 12 words seed phrase. You will notice that currently you have 0 ETH in your wallet. To deploy contract on Ethereum network one need some amount of Ether.

We will not deploy our contract to main network as this is just demo. We will publish this contract to the test network.

First you need some Ether, right? On test network we work with fake free ethers. One just need to claim some of those from Faucet.

Metamask will now ask you to withdraw some funds from your wallet in order to purchase this transaction. Confirm that. We see that the transaction has been successful.

Click on the uri from the terminal which looks like : ropsten. It will navigate us to etherscan. When we go to this uri we will see details about our transaction.

Click on contract hash to explore more. Everything is public on the blockchain, even our code. Solidity developers have no room for errors!

Click on the contract tab and you will see our compiled bytecode. Now you can go to Token Tracer to see details of our Blockonomi Token.

You can see 3 optional rules that we defined earlier. Now check your wallet. You will see that the Ether that we paid for deploying the smart contract on Ropsten has been removed.

That wraps up our tutorial, by following these steps and our code samples you should be able to deploy your own Ethereum ERC Token.
