Smart Contract Development Roadmap

Smart contract development is one of the most in-demand skills in Web3. Here's a practical roadmap from beginner to professional.

Prerequisites Solid understanding of blockchain fundamentals: hashes, Merkle trees, consensus mechanisms, EVM basics. The Bitcoin and Ethereum yellow papers are worth reading at least once.

Phase 1 — Solidity fundamentals Start with Solidity by Example. Write your first token (ERC-20). Deploy to a testnet using Hardhat or Foundry. Understand gas, storage, and memory.

Phase 2 — DeFi protocols Study existing protocols: Uniswap v2/v3 AMM logic, how Aave lending works, Compound interest models. Re-implement simplified versions from scratch.

Phase 3 — Security This is non-negotiable. Take the Secureum bootcamp. Read the Known Attacks list. Learn fuzzing with Echidna. Practice on OpenZeppelin's Ethernaut.

Phase 4 — Advanced patterns Upgradeable proxies, multi-sig wallets, cross-chain bridges, ZK circuits. Build a portfolio of non-trivial projects on mainnet.

Phase 5 — Get paid Target protocol engineering roles at DeFi teams. Practice live Solidity coding under pressure. Know your compensation benchmarks on BlockJob.
