Write Smart Contract In Solidity
In this article, we will walk you through the steps required to write smart contract and deploy it on the Ethereum blockchain.
We will cover the basics of Solidity syntax, the development environment, and the tools needed to write, compile, and deploy your first smart contract.
Write Smart Contract
Smart contracts are self-executing computer programs that automatically enforce the terms of an agreement when certain predefined conditions are met.
The first step in writing a smart contract in Solidity is defining the contract.
You can do this by creating a new file with a .sol extension and then defining the contract
Remix IDE is used to compile and run Solidity code.
Step 1: Enter the given code in the Remix IDE Code Section.
Example:
Step 2: Click on Start to Compile under Compile Tab.
Step 3: Click Deploy under the Run Tab.
Step 4: Choose SolidityTest at 0x… in the drop-down list under Run Tab.
Step 5: The result can be viewed by clicking the getResult button.
Output
The following program returns the product of two numbers as shown below:
Example:
Output:
Example Explanation
Above example is a simple Solidity smart contract that defines a contract called SolidityTest.
The contract contains two unsigned integer variables called mrx and ample that are assigned the values of 4 and 5, respectively, in the constructor function.
The getProduct function is defined with the public visibility modifier, meaning that it can be accessed by other contracts and external accounts.
The getProduct function returns the product of the mrx and ample variables, which is calculated as mrx * ample.
The pragma statement at the top of the contract specifies the version of the Solidity compiler that should be used to compile the contract.
Congratulation! you just Write Smart Contract in Solidity.
