"Milestone-escrow crowdfunding dApp" — It's a fundraising app where donations don't go straight to the creator. They're locked in a smart contract (escrow) and released in chunks ("milestones") only as the creator proves progress.

"Scaffold-ETH 2–style yarn-workspaces monorepo" — The whole project is one repository containing two sub-projects ("packages"), managed together with Yarn workspaces. Scaffold-ETH 2 is a popular starter kit for Ethereum apps; we follow its layout.

The two packages:

• hardhat — the smart contract side (the Solidity code that runs on the blockchain). "Hardhat" is the tool used to compile, test, and deploy it. This is the "on-chain accountability layer" — the rules about holding and releasing money that no one can secretly change.
• nextjs — the website (built with Next.js) that people actually click around in: connect wallet, donate, view campaigns, etc.

"Everything that shouldn't depend on trust lives on-chain; the frontend is 'just' a viewer/driver over contract state" — This is the key design idea:

• Anything that must be trustworthy — who donated, how much, what's released, the proof, reputation — is stored and enforced by the blockchain contract, where it's public and tamper-proof.
• The website itself stores nothing important. It just reads the contract's data to display it ("viewer") and sends your actions to the contract when you click a button ("driver"). If the website disappeared, all the money and records would still be safe on-chain.
