DeFi Developer Road Map is an open-source educational handbook that helps developers learn decentralized finance and blockchain application development. It organizes technical concepts, programming tools, security references, and learning resources into a structured roadmap. The guide introduces distributed ledgers, cryptography, Ethereum, and decentralized application architecture. Developers can explore Solidity, smart contract frameworks, testing utilities, and frontend integration tools. Additional sections cover stablecoins, NFTs, decentralized exchanges, sidechains, and zero-knowledge proofs. Security materials address smart contract vulnerabilities, auditing practices, and common attack vectors. The repository also explores maximal extractable value and blockchain infrastructure. Community translations make the roadmap available in multiple languages.
