Building Decentralized Wallets with EOSJS

Blockchain development can feel overwhelming with its complex cryptography and unique network architectures. This text-based course simplifies the process, guiding you through the fundamentals of interacting with the EOS blockchain to build your own decentralized wallet applications. You will start with the core concepts of public-key cryptography, blockchain accounts, and state history before writing a single line of code. Through clear, step-by-step written explanations, you will learn how to connect to decentralized networks and manage digital assets securely. What you'll learn: Understand the core architecture of the EOS blockchain and its account permission structure; Configure connection clients using modern EOSJS library patterns; Create secure functions to generate keys, import accounts, and manage private keys in memory; Build transaction payloads to transfer tokens and interact with smart contracts; Implement modern security practices to protect user data from common web vulnerabilities; Read and display real-time blockchain state, balance history, and transaction logs. You will progress from basic blockchain terminology to configuring node connections, handling cryptographic keys, and executing secure on-chain transactions. This course is designed specifically for web developers who are new to blockchain technology and want to expand their skills into decentralized application development without any prior smart contract experience. Start your journey into decentralized web development today.
