Sample Contracts

Following is a simple example

//SPDX-License-Identifier: MIT

pragma solidity 0.8.0;

contract HelloWorld {
    string private word;

    constructor (string memory _word) {
        word = _word;

    function setWord(string memory _word) external returns (bool) {
        word = _word;
        return true;

    function hello() public view returns (string memory) {
        return word;
