How to develop DApp on BSC

Binance Smart Chain (BSC) is one of the best blockchain networks for developing DApps. The BSC blockchain network was launched in September 2020 by Binance, one of the largest cryptocurrency exchanges in the world. BSC is a parallel blockchain to the main Binance Chain, but it is designed to be more compatible with the Ethereum network, specifically the Ethereum Virtual Machine (EVM).

To develop a Binance Smart Chain (BSC) DApp, you will need the following:

  1. Programming Language: Binance Smart Chain supports multiple programming languages, but Solidity is the most commonly used language for developing smart contracts on BSC.
  2. Development Environment: Use any integrated development environment (IDE) that supports Solidity. Popular options include Remix, Visual Studio Code with the Solidity extension, and Truffle.
  3. BSC Node: You will need to connect to a BSC node to interact with the BSC network. It is possible to run your own BSC node or use a third-party node provider.
  4. Metamask: Metamask is a popular browser extension wallet that allows users to interact with decentralized applications on BSC. You can use Metamask to deploy your smart contracts and test your DApp.
  5. Smart Contracts: Write and deploy smart contracts on the BSC network to create the logic of your DApp.
  6. User Interface: You will need to design and implement a user interface (UI) for a DApp to interact with the smart contracts. You can use any front-end framework, such as React or Angular, to develop the UI.
  7. Testing: It is essential to test a DApp thoroughly to ensure it is secure and functioning as expected. It is functional to use tools like Truffle or Remix for testing your smart contracts and UI.
  8. Deployment: Once a DApp is fully developed and tested, you can deploy it to the BSC network. You can use various deployment tools, such as Remix or Truffle, to deploy your DApp.

BSC programming languages

As we have mentioned Solidity is the most commonly used BSC language, which is the same programming language used for developing smart contracts on the Ethereum network.

Apart from Solidity, BSC also supports other programming languages:

  • Vyper, which is a contract-oriented, Pythonic programming language that is similar to Solidity. 
  • YUL, a low-level intermediate language that can be used to write efficient and optimized smart contracts
  • LLL (Low-Level Lisp-like Language) is another low-level language that can be used to write smart contracts on BSC. It is similar to YUL in that it is designed to be a more flexible and customizable alternative to Solidity.
  • Bamboo Relay Solidity: Bamboo Relay Solidity is a modified version of Solidity that is optimized for writing decentralized exchange (DEX) smart contracts on BSC. It includes specific features and functions that are useful for building DEXs.

However, it’s worth noting that Solidity is the most widely used language for developing smart contracts on BSC, and most of the existing DApps on BSC are built using Solidity. 

BSC node

A Binance Smart Chain (BSC) node is a software application that connects to the BSC network and allows you to interact with it. Nodes are an essential component of the BSC network as they help to maintain the network’s security and decentralization.

There are two types of nodes on the BSC network:

  1. Full Nodes: Full nodes download and store a complete copy of the BSC blockchain. They are responsible for verifying transactions and blocks, maintaining network consensus, and propagating transactions and blocks to other nodes on the network. Full nodes are the most secure and decentralized type of node, but they require a significant amount of storage space and processing power.
  2. Light Nodes: Light nodes do not download and store a complete copy of the BSC blockchain. Instead, they rely on full nodes to provide them with the necessary information to validate transactions and blocks. Light nodes are less secure and decentralized than full nodes, but they require less storage space and processing power.

You can run your own BSC node by installing a node software such as Geth, Parity, or Besu, and connecting it to the BSC network. Alternatively, you can use a third-party node provider such as NOWNodes. This provider offers easy-to-use APIs that allow you to interact with the BSC network without running your own node.

Metamask for BSC DApp

Metamask is a popular browser extension wallet that allows users to interact with decentralized applications (DApps) on various blockchain networks, including Binance Smart Chain (BSC). Metamask provides a user-friendly interface for managing cryptocurrency wallets and interacting with smart contracts on the BSC network.

To use Metamask with a BSC DApp, you will first need to install the Metamask browser extension and create a BSC wallet within the Metamask interface. Once you have created a BSC wallet, you can connect it to your DApp by selecting the BSC network in the Metamask dropdown menu and entering the BSC network details.

Once your Metamask wallet is connected to the BSC network, you can use it to interact with the smart contracts in your DApp. For example, you can use Metamask to send and receive cryptocurrency, approve transactions, and sign messages.

Using Metamask with your BSC DApp can help to improve the user experience by providing a familiar and convenient wallet interface. It can also help to improve the security of your DApp by allowing users to securely manage their cryptocurrency assets without exposing their private keys to the DApp.

React or Angular for BSC UI 

Both React and Angular are popular front-end frameworks that can be used to develop user interfaces for Binance Smart Chain (BSC) DApps.

React is a JavaScript library that is widely used for building user interfaces. It is highly flexible, easy to learn, and has a large and active community. React is often used in conjunction with other libraries and tools, such as Redux and Web3.js, to build DApps on BSC.

Angular is a complete front-end framework that is designed to be highly modular and scalable. It provides a robust set of features for building complex user interfaces, including built-in support for routing, forms, and HTTP requests. Angular is a more opinionated framework compared to React, which can make it more difficult to learn but can be more efficient for building larger and more complex DApps.

Ultimately, the choice between React and Angular will depend on your specific requirements and preferences. React is a popular choice for building smaller to medium-sized DApps with a simple user interface, while Angular is a better choice for building larger and more complex DApps that require more advanced features and functionality.

Both React and Angular have strong communities and extensive documentation, making them accessible and easy to learn for developers of all levels of experience.

Truffle and Remix for BSC DApp

Truffle and Remix are two popular tools used for developing, testing, and deploying Binance Smart Chain (BSC) DApps.

Truffle is a development framework that provides a suite of tools for building and deploying smart contracts on BSC. With Truffle, you can write and test your smart contracts in a development environment, automate the contract compilation and deployment process, and manage the entire development lifecycle of your DApp.

Remix is an online development environment for building and testing smart contracts on BSC. It provides an easy-to-use interface for writing, testing, and deploying smart contracts, making it a popular choice for developers who are new to BSC.

Both Truffle and Remix are highly useful tools for BSC DApps, and they offer different benefits depending on your specific needs and preferences. 

For example, Truffle provides a more comprehensive development framework with more features and customization options, while Remix provides a simpler and more straightforward interface for writing and testing smart contracts.

Overall, using Truffle and Remix in conjunction with other tools such as Metamask and BSC nodes can help to streamline the development and deployment process for your BSC DApp, and ensure that your smart contracts are tested and secure before being deployed to the network.
