Decentralized applications (dApps) combine smart contracts with traditional web frontends.
Frontend: React, Vue, or similar
Smart Contracts: Business logic on-chain
Web3 Library: Connects frontend to blockchain
Wallet: User authentication (MetaMask)
Backend (optional): Indexing, caching
Smart Contracts:
- Hardhat or Foundry (development framework)
- Solidity (language)
- OpenZeppelin (secure contract libraries)
Frontend:
- React + Next.js
- ethers.js or viem (blockchain interaction)
- wagmi or web3-react (hooks)
- RainbowKit or ConnectKit (wallet UI)
Infrastructure:
- Alchemy or Infura (RPC nodes)
- The Graph (indexing)
- IPFS/Arweave (decentralized storage)
1. Design your contracts
2. Write and test on local network
3. Deploy to testnet
4. Build frontend
5. Get contract audited (for production)
6. Deploy to mainnet
Week 1-2: Solidity basics (CryptoZombies)
Week 3-4: Hardhat + testing
Week 5-6: Frontend integration
Week 7-8: Build a simple project
- ethereum.org/developers
- Speedrun Ethereum
- Buildspace
- Alchemy University
- Build in public, share progress
- Start simple (todo list, basic token)
- Always write tests
- Get feedback early
