Crypto for Coders

Unlock the future of finance by learning to build it.

Whether you're a software developer curious about the buzz around blockchain, or a coding enthusiast looking to break into Web3, Crypto for Coders: From Beginner to Blockchain Dev is your ultimate guide to becoming a blockchain developer from the ground up.

This book bridges the gap between traditional programming and the fast-evolving world of decentralized technologies. You’ll go from understanding the fundamentals of cryptocurrencies and blockchains to building smart contracts, deploying decentralized applications (DApps), and contributing to real-world blockchain projects.

Inside this book, you’ll learn:

The foundations of blockchain technology, Bitcoin, and Ethereum—explained in a coder-friendly way

How cryptographic concepts like hashing, digital signatures, and consensus mechanisms actually work under the hood

The difference between Layer 1 and Layer 2 solutions—and why it matters for scalability and development

How to set up a full-stack blockchain development environment using tools like MetaMask, Hardhat, Truffle, and more

Solidity programming for Ethereum smart contracts—with step-by-step walkthroughs and real use cases

Building and deploying your first DApp (decentralized application) from scratch

How to interact with smart contracts using Web3.js and Ethers.js

Security best practices for smart contract development—avoiding common vulnerabilities

An overview of other blockchain ecosystems like Solana, Polkadot, and Avalanche for multi-chain development

How to contribute to open-source crypto projects and get noticed in the Web3 dev community

Unlike theoretical books that leave you overwhelmed with jargon, Crypto for Coders is packed with hands-on examples, practical tutorials, and real-world applications—making it perfect for developers who learn by doing.

Whether you're aiming to land your first blockchain dev role, build your own crypto startup, or simply expand your skill set into the future of tech, this book will help you go from zero to blockchain hero—without the fluff.
