The Blockchain Developer trek
Cryptography, Ethereum, Solidity, DeFi protocols, smart contract security, NFTs, Layer 2 scaling, and Web3 frontend integration.
Cryptography & distributed systems foundations
The cryptographic primitives that blockchains are built on, and the distributed systems properties they achieve.
Bitcoin & blockchain fundamentals
How Bitcoin works under the hood: UTXO model, the scripting language, mining, and what Satoshi's whitepaper actually says.
Ethereum & EVM
The Ethereum Virtual Machine, accounts model, gas, and how Ethereum differs from Bitcoin.
Solidity fundamentals
Writing smart contracts: types, functions, state variables, events, modifiers, and Solidity patterns.
Smart contract development
Development toolchains, testing frameworks, deployment scripts, and the professional workflow for Solidity development.
DeFi protocols & patterns
How DeFi works: AMMs, lending protocols, yield aggregators, and the patterns that underpin billions in TVL.
Smart contract security
The most critical skill for Solidity developers: common vulnerabilities, security patterns, and auditing methodologies.
NFTs & token standards
ERC-721, ERC-1155, royalties, metadata, and the developer patterns for building NFT projects.
Layer 2 & scaling solutions
Rollups, state channels, and the L2 ecosystem that makes Ethereum usable at scale.
Web3 frontend integration
ethers.js, wagmi, viem, and connecting React frontends to smart contracts.
Advanced patterns & protocol design
Upgradeable contracts, governance, multi-sig, and the architectural patterns for production protocol development.
Capstone — ship a DeFi protocol
Design, build, audit, and deploy a complete DeFi protocol with frontend, governance, and security review.
Trek complete. What's next?
You've walked the full roadmap. Now ship the capstone, write about it, and share the path with the next engineer who needs it.
