• Unlike the starter code in the scaffold-eth-challenges repo, this one is based on a recent Scaffold Eth master (10 dec 2021)

• this app offers more than the core staker contract functionality
• users can create custom staker contracts and interact with them

• It is possible to withdraw for others because the challenge required it, but I personally wouldn't allow it in production (see contract comments for why).
• There is a countdown timer which only updates on new blocks. Time left until deadline is only read from contract and depends on current block. UX not optimal this way.
  • => if you try this locally keep in mind that new blocks are only mined if necessary. You can use the faucet to produce new blocks.

everything you need to build on Ethereum! 🚀

🧪 Quickly experiment with Solidity using a frontend that adapts to your smart contract:

Prerequisites: Node plus Yarn and Git

clone/fork 🏗 scaffold-eth:

git clone https://github.com/scaffold-eth/scaffold-eth.git

install and start your 👷‍ Hardhat chain:

cd scaffold-eth
yarn install
yarn chain

in a second terminal window, start your 📱 frontend:

cd scaffold-eth
yarn start

in a third terminal window, 🛰 deploy your contract:

cd scaffold-eth
yarn deploy

🌍 You need an RPC key for production deployments/Apps, create an Alchemy account and replace the value of ALCHEMY_KEY = xxx in packages/react-app/src/constants.js

🔏 Edit your smart contract YourContract.sol in packages/hardhat/contracts

📝 Edit your frontend App.jsx in packages/react-app/src

💼 Edit your deployment scripts in packages/hardhat/deploy

📱 Open http://localhost:3000 to see the app
