Smart Contracts

A simple Ethereum smart contract code example written in Solidity.

This contract is called "SimpleStorage" and allows the user to store and retrieve a value.

pragma solidity ^0.8.0;
contract SimpleStorage {
  uint256 storedData;
  function set(uint256 x) public {
    storedData = x;
  function get() public view returns (uint256) {
    return storedData;

In this example, we have defined a contract called "SimpleStorage" that contains a variable storedData of type uint256.

The contract has two functions:

set(uint256 x): This function allows the user to set the value of storedData to a new value x.

get(): This function allows the user to retrieve the current value of storedData.

The public keyword indicates that these functions can be called from outside the contract. The view keyword indicates that the function does not modify the state of the contract.

Once this smart contract is deployed on the Ethereum network, anyone can call the set() function to set the value of storedData, and the get() function to retrieve the current value.
