Decentralized Application (DApp) Development (Coursera)

Participants will acquire the necessary skills to develop front-end interfaces for DApps. They will learn modern web development technologies such as HTML, CSS, and JavaScript frameworks (e.g., React, Angular) to create engaging and user-friendly interfaces that interact with the underlying blockchain.

The course will cover the integration of smart contracts with DApps. Participants will learn how to interact with smart contracts from the front-end using web3.js or similar libraries, enabling DApps to read from and write to the blockchain, execute transactions, and update contract states.

Participants will gain insights into designing DApp architecture and optimizing user experience. They will learn best practices for structuring DApps, handling data flows between the front-end and smart contracts, and implementing intuitive user interfaces that seamlessly interact with the blockchain.

The course will cover essential aspects of testing, deploying, and maintaining DApps. Participants will learn how to write comprehensive tests for their DApp's smart contracts and front-end components, deploy DApps to testnets or the mainnet, and ensure ongoing maintenance and updates to keep their DApps functional and secure.
