Lesson 4

Finalizing Your Tron DApp and Understanding Next Steps

Welcome to the final lesson of this course! You've made a lot of progress so far, going from setting up your development environment, learning Solidity basics, creating and deploying your smart contract, to creating your first DApp. In this lesson, we won't introduce any new features. Instead, we'll take a look at what you've accomplished, and provide some guidance for what you might want to learn next in your journey as a Tron DApp developer.

Review of Your DApp

So far, you have built a decentralized application that can interact with a smart contract on the Tron blockchain. The DApp consists of a simple HTML frontend and a JavaScript backend. The JavaScript uses TronWeb to communicate with the Tron network, specifically with your Storage smart contract.

This DApp allows users to store a number in the smart contract and retrieve it. Although it’s a simple example, it encapsulates the core principles of DApp development: writing a smart contract, deploying it to the blockchain, and creating an interface for users to interact with it.

Next Steps in Your Tron DApp Development Journey

As you continue your journey in developing DApps on the Tron blockchain, here are a few concepts and topics you may want to explore:

Advanced Solidity Concepts: While we have covered basic Solidity in this course, there is much more to learn, including more complex data types (like structs and mappings), function modifiers, error handling, and more.

Advanced DApp Features: There are many features you can add to your DApps, like integration with TronLink, listening for and reacting to smart contract events, or allowing users to send and receive TRX or TRC10/TRC20 tokens.

Security: One of the most important aspects of smart contract and DApp development is security. You should learn about common smart contract vulnerabilities and how to avoid them, and how to write tests for your contracts.

Frontend Development: This course has focused on the blockchain/smart contract side of DApp development, but developing a good user interface is equally important. Consider learning more about frontend development, including more complex HTML/CSS, JavaScript, or frontend libraries/frameworks like React.

Conclusion
