Creating & Deploying Smart Contracts




Ethereum was introduced into the blockchain world in 2015. It was an incredible revolution of blockchain technology since Satoshi Nakamoto’s white paper dropped in 2008, showcasing Bitcoin as the latest wonder of the world. Then came Vitalik Buterin, a Canadian-Russian programmer who probably was a little more outgoing than Nakamoto.

Ethereum would have been another Bitcoin that didn’t bring anything different to the table but for the smartness of Buterin who thought thoroughly about creating and deploying smart contracts. Ethereum’s success is significantly ascribed to his decision to design a smart contract and implement it. From this article on how to create a smart contract you can expand our knowledge in smart contracts creation, and today we will cover it briefly.


The blockchain platform, Ethereum, allows developers to create Ethereum smart contracts. Ethereum is one of the blockchain platforms that execute arbitrary codes so that you can perform any program on Ethereum. Now that’s what I call flexibility. It is an open infrastructure that eases the initiation and completion of projects using smart contracts. So what is a smart contract?


Smart contracts are simply programs or a transaction protocol stored on a blockchain that is meant to execute automatically when predetermined conditions are met. They are automated agreements in which all parties involved are already certain of the outcome before the execution.

They are essential tools for automation, transparency, and time-saving. To make a smart contract on Ethereum, you must have a goal such as simplifying business and trade between you and anonymous or identified parties without the need for a middleman. Smarts contracts eliminate all bottles that accompany formality and costs associated with traditional transactions without compromising authenticity and safety.


Developing Ethereum smart contracts for beginners is made as easy as possible for you in this article. First, get to know MetaMask. Metamask allows interaction with smart contracts and dApps on the internet without the requirement of installing blockchain or any apps. All you should do is add MetaMask as a Chrome extension, create a wallet and submit Ether as required. Though MetaMask is currently available for the Google Chrome browser, you may have to wait a little longer to have it on a browser such as Firefox.

Once you have downloaded MetaMask and added it as a Chrome extension, import an already created wallet or create a new wallet. Of course, there must be some Ether in your wallet to build your own smart contract and for Ethereum smart contract deployment on the network.

Once installed, click on the icon at the top right side of your browser. Click on ‘Create Wallet’ on the new pop-up page. You will also have to agree to the platform’s terms and conditions by clicking on “I Agree” to continue. After this, you will create a strong password. Right after creating your password, you will get a secret backup phrase automatically generated to restore your account. You must write the phrase on a piece of paper and store it in a secure place so you don’t lose all your Ethers.

To design a smart contract, you must ensure that you properly checked into the “Main Ethereum Network”, if the check icon does not mark you as on the Main Ethereum Network then you are in the wrong place and page. You have also failed in creating and deploying smart contracts.

Next, you will select any test network of your choice. The following are the test networks you will possibly come across in your MetaMask wallet;

  • Kovan Test Network
  • Rinkeby Test Network
  • Goerli Test Network
  • Robsten Test Network

It is important to note that the Ethers you find on these testing networks are not real Ethers, they are merely for testing purposes only. You get to add some of these dummy Ether coins to your MetaMask wallet. Proceed with using editor remix to write the smart in Solidity.

It is safe to say at this point that you must be able to compile Ethereum smart contract code to design a smart contract. To complete the test, deploy the smart contract by pressing the Remix window’s button. The address of the smart contract created will be visible on the right side of the Remix window. You can verify your smart contract on Etherscan.
