Ship real things: a tip jar dApp, an NFT minter, an on-chain tic-tac-toe game, a prediction market frontend. Uses Next.js + wagmi + viem for the frontend, Hardhat + OpenZeppelin for the contracts.

Prerequisites:Solidity, OpenZeppelin & ERCs

01Your first dApp — a tip jarsolidity

A contract that accepts ETH, emits an event on each tip, and lets the owner withdraw. ~30 lines of Solidity.
