By the end of this lesson, you will be able to:
In this lesson, we provide a detailed demo on how to create, compile and deploy a simple smart contract on the BNB Smart Chain Testnet using the Replit IDE. Remember that, BNB Smart Chain is the component of the BNB Chain ecosystem that is equipped with the smart contract programmability and hence any smart contract or dapps are in essence deployed on the BNB Smart Chain.
Replit is a coding platform that allows you to write code and host apps. Replit supports Solidity programming language and provides all of the features and functionality that are required by Web3 developers for creating and deploying smart contracts.
In this tutorial, we explain how to build and deploy a solidity smart contract on the BNB Smart Chain Testnet using the Replit IDE and the Replit Solidity Template (Solidity starter beta). For this hands-on guide, readers are encourged to perform the specified tasks along for a better understanding.
For additional examples about Solidity with Replit, you can read the article qqqq vbh**Get started with Replit! or check Replit Solidity documentation and Escrow contract tutorial**
There is no need for any local environment settings for deploying solidity smart contracts on BNB Smart Chain using Replit.
All you require is a browser-based Web3 wallet (e.g. MetaMask) to interact with the BNB Smart Chain Testnet and deployed contracts. If you are already using MetaMask, it is recommended to create a new account for testing with Replit. You can do this from the account menu, which appears when you click on the account avatar in the top right corner of MetaMask interface.
You must set up all of the following Pre-requisites to be able to deploy your solidity smart contract on BSC:
When using Replit IDE, every Repl that you create is a fully functional development and production environment. Follow the steps to create a Solidity starter Repl:
Delete the contents of the contract.sol file and paste the following solidity code into this file.
Make sure that you have followed the list of Pre-requisites above so that you are ready to deploy and interact with your smart contract:
Once your contract has been deployed, it will show up as expandable boxes below the drop-down box. Expand it and take a look at all the different functions available. You can now interact with your contract using the provided user interface or from a sharable URL shown on the interface.
Replit allows you to publish your projects to a personal profile. After publishing, projects will show up on your spotlight page for others to explore, interact with, clone, and collaborate.
See Publish your Repl.
This tutorial guided you through the basics of creating and deploying a smart contract using the Replit IDE. We also provided steps on how to interact with the deployed contract online and publish your replit project. This tutorial uses testnet, however, the exact same instructions and sequence will work on the mainnet as well.
