Master Solidity from scratch in this hands-on, 4-week course designed for developers entering the Ethereum ecosystem. You'll go from zero to deploying production-ready smart contracts, covering everything from basic syntax and data types to advanced patterns like proxy contracts and gas optimization. Each session combines theory with live coding, and you'll walk away with a portfolio of deployed contracts on testnets.
Unlock the power of zero-knowledge proof systems in this intensive course bridging cryptographic theory and practical application. Starting from the mathematical foundations of SNARKs and STARKs, you'll progress to building real ZK circuits using Circom and SnarkJS. By the end, you'll understand how ZK proofs enable both privacy and scalability on Ethereum, and you'll have built your own privacy-preserving application.
Dive deep into Uniswap V4's revolutionary hook system — the most powerful extension mechanism in DeFi. This course covers the complete hook lifecycle, from pool creation to swap execution, and teaches you to build custom AMM logic that was previously impossible. You'll implement dynamic fee structures, TWAMM patterns, limit orders, and MEV-resistant hooks, gaining the skills to create entirely new DeFi primitives.
Learn to think like an attacker and defend like an auditor. This course provides a systematic approach to smart contract security, covering the full taxonomy of vulnerabilities from reentrancy and flash loan attacks to subtle logic bugs and oracle manipulation. You'll practice with real-world exploit case studies, learn formal verification with Certora, and participate in a live audit workshop using production contracts.
Build the next generation of Ethereum UX with ERC-4337 account abstraction. This course takes you through the complete stack — from understanding UserOperations and Bundlers to implementing smart accounts with social recovery, session keys, and gasless transactions. You'll build a production-ready smart wallet that makes Web3 as intuitive as Web2, solving the onboarding problem that has held back Ethereum adoption.
