Web3 for Web2 Developers
A practical Web3 course for experienced Web2 developers, with no prior blockchain knowledge assumed. Twenty-one chapters take you from consensus and wallets through Solidity contracts, testing, tokens, frontend integration with wagmi and viem, payments, oracles, DeFi, Bitcoin's UTXO model and Lightning, L2 deployment, a full Solana deep dive, and a security auditing mindset. Every chapter mixes mental models with runnable code, a decision gate, and a hands-on checklist. All work happens on testnets; no real funds required. It ends with a capstone: a deployed full-stack testnet dApp with a written security self-review, which earns the certificate.
