How to Create Smart Contracts & Execute on Ethereum?

Smart contracts can be created and run on blockchain networks. Ethereum is also one of the blockchain systems that can run any software, making it possible to run any programme on it.

This article will walk you through the process of establishing and implementing Ethereum Smart Contracts.

Step 1: Go to meta-mask and make a wallet.

Install MetaMask and enable it in your Chrome browser. After it has been installed, go to the top right corner of the browser page and click on the symbol. It will open in a new tab of the browser when you click on it.

To continue, click “Create Wallet” and agree to the terms and conditions by clicking “I agree.” You’ll be prompted to create a password.

It will email you a secret backup phrase to use for backing up and restoring the account when you create a password. This phrase can take away your Ethers if you reveal it or share it with someone.

You should either write this phrase down on a secure piece of paper or put it on an external encrypted hard drive where no one will be able to access it.

The next step is to double-check that you’re connected to the “Main Ethereum Network.” You’ve arrived in the right area if you see a checkmark next to “Main Ethereum Network.”

Step 2: Choose a test network.

In your MetaMask wallet, you may also locate the following test networks:

• Network of Robsten Tests

• Network of Kovan Tests

• Rinkeby Test Network (Rinkeby Test Network)

  • The Goerli Test Network is a test network in Goerli, Germany.

Step 3: Fill your wallet with dummy Ethers.

You’ll need some fake ethers in your MetaMask wallet if you wish to test the smart contract.

If you want to test a contract on the Robsten test network, for example, choose it and your account will be credited with 0 ETH.

Click the “Deposit” and “Get Ether” buttons under Test Faucet to add dummy ethers.

You can start writing smart contracts in the Solidity programming language on the Remix Browser IDE once the dummy ethers have been loaded to the wallet.

Step 4: Write the smart contract in Solidity using editor remix.

To write our Solidity code, we’ll use the Remix Browser IDE. Because it comes with many features and provides a thorough development experience, the remix is the ideal option for building smart contracts.

Step 5: Make a file with the. sol extension.

To create a.sol extension file, open Remix Browser and click the Add icon on the upper left side, adjacent to the browser.

Step 6: Put your contract into action.

By pressing the deploy button on the right-hand side of the Remix window, you can deploy the smart contract to the Ethereum test network.

Wait until the transaction is completed before proceeding.

The address of the smart contract will be revealed on the right-hand side of the remix window after the transaction commits properly.

Steps to deploy Ethereum Smart Contracts

  • At metamask, switch to the main ethereum network to activate your smart contract.
  • Incorporate some genuine ethers.
  • Once again, use remix to deploy your smart contract as described in the previous steps.
  • Once a smart contract has been successfully deployed, look for your smart contract address there.
  • Now you must verify your smart contract by selecting “verify contract” from the drop-down menu.
  • Copy and paste your smart contract code into Etherscan. To compile your code, use the same compiler version as you used for the remix.
  • If you selected optimization at a remix, set “optimization” to Yes; otherwise, set “optimization” to No.
  • Select Verify.
  • If there are no issues, it will just take a few minutes for your smart contract to go live.
  • Etherscan now allows you to perform smart contract procedures.
