The line\u00a0string public message\u00a0declares a public state variable called\u00a0message\u00a0of type\u00a0string. You can think of it as a single slot in a database that you can query and alter by calling functions of the code that manages the database. The keyword\u00a0public\u00a0automatically generates a function that allows you to access the current value of the state variable from outside of the contract. Without this keyword, other contracts have no way to access the variable.<\/p>\n<p>The\u00a0constructor\u00a0is a special function run during the creation of the contract and cannot be called afterward. In this case, it takes a string value\u00a0initMessage, stores the value in the\u00a0memory\u00a0data storage area, and sets\u00a0message\u00a0to that value.<\/p>\n<p>The\u00a0update\u00a0function is another public function that is similar to the constructor, taking a string as a parameter, and updating the\u00a0message\u00a0variable.<\/p>\n<h4><strong>Compile Smart Contract<\/strong><\/h4>\n<ul>\n<li>Go to the\u00a0Solidity Compiler\u00a0tab (below the search button)<\/li>\n<li>Select compiler version to\u00a00.5.10<\/li>\n<li>Now, compile\u00a0HelloWorld.sol<\/li>\n<li>After successful compilation, it will show a green tick mark on the\u00a0Compiler\u00a0tab button<\/li>\n<\/ul>\n<h4><strong>Deploying to the SECRYPT Testnet<\/strong><\/h4>\n<p>Now, we have to deploy our smart contract on SECRYPT, SECRYPT Network&#8217;s Testnet. Not only does it cost money (e.g., gas fees) to deploy a smart contract on SECRYPT Mainnet, but also, the contract is immutable and can&#8217;t be changed once deployed. Therefore, it&#8217;s best to first deploy your smart contract to the Testnet first.<\/p>\n<p>To deploy to the SECRYPT testnet, we have to connect to the Web3 world which can be accomplished by using any of the services like Metamask, Brave, Portis, etc. We will be using Metamask in this tutorial. Please follow this\u00a0guide to set up a Metamask Account.<\/p>\n<ul>\n<li>Open Metamask.
