Description
You already know React. This course closes the gap between “I understand blockchain” and “I shipped a dApp real users can trust with their wallet.” Most tutorials stop at a wallet-connect button; this one takes you through the parts that actually break in production — gas estimation, reverted transactions, stale event caches, and metadata that renders as a broken image on OpenSea.
Over 18 hours across 8 modules you build a complete, production-shaped application: connect MetaMask, Coinbase Wallet, and WalletConnect through wagmi + viem; read and write smart contract state with typed clients; index historical and live on-chain events without running a backend indexer; pin NFT metadata and images to IPFS the correct way; implement Sign-In with Ethereum for real session auth; gate routes and content by token or NFT ownership; and build a minting page with gas estimation, revert-reason handling, and full pending/confirmed/failed transaction UX, including Merkle-tree allowlists.
The capstone has you ship a token-gated minting dApp end to end and deploy it to Vercel with environment-based RPC config and wallet-aware analytics, then review your build against a grading rubric.
Every lesson is hands-on: you are writing the actual client code, ABIs, and UI states that show up in production dApps, not toy demos. You’ll leave with a deployed project you can put in a portfolio, a client delivery, or your own product, plus the patterns to debug the transaction failures and wallet edge cases that trip up most front-end teams moving into web3.
Who it’s for: mid-level front-end or full-stack developers comfortable with React and TypeScript who need to add verifiable web3 shipping experience for a job, a client engagement, or their own project. No prior Solidity authorship is required — you’ll be consuming contracts and ABIs, not writing them.
By the end you can confidently connect any EVM wallet, transact safely against mainnet or testnets, serve correct NFT metadata, authenticate with wallet signatures, and deploy a hardened, analytics-instrumented production build.
