🏗👷🏾 Scaffold-ETH Challenges
learn how to use 🏗 scaffold-eth to create decentralized applications on Ethereum. 🚀
🚩 Challenge 0: 🎟 Simple NFT Example 🤓
🎫 Create a simple NFT to learn basics of 🏗 scaffold-eth. You'll use 👷♀️ HardHat to compile and deploy smart contracts. Then, you'll use a template React app full of important Ethereum components and hooks. Finally, you'll deploy an NFT to a public network to share with friends! 🚀

🚩 Challenge 1: 🥩 Decentralized Staking App
🦸 A superpower of Ethereum is allowing you, the builder, to create a simple set of rules that an adversarial group of players can use to work together. In this challenge, you create a decentralized application where users can coordinate a group funding effort. If the users cooperate, the money is collected in a second smart contract. If they defect, the worst that can happen is everyone gets their money back. The users only have to trust the code.
🚩 Challenge 2: 🏵 Token Vendor 🤖
🤖 Smart contracts are kind of like "always on" vending machines that anyone can access. Let's make a decentralized, digital currency. Then, let's build an unstoppable vending machine that will buy and sell the currency. We'll learn about the "approve" pattern for ERC20s and how contract to contract interactions work.

🚩 Challenge 3: 🎲 Dice Game
🎰 Randomness is tricky on a public deterministic blockchain. In this challenge you will explore creating random numbers using block hash and how that may be exploitable. Attack the dice game with your own contract by predicting the randomness ahead of time to always roll a winner!

🎉 Checkpoint: Eligible to join 🏰️ BuidlGuidl
The BuidlGuidl is a curated group of Ethereum builders creating products, prototypes, and tutorials to enrich the web3 ecosystem. A place to show off your builds and meet other builders. Start crafting your Web3 portfolio by submitting your DEX, Multisig or SVG NFT build.
⚖️ Build a DEX Challenge
💵 Build an exchange that swaps ETH to tokens and tokens to ETH. 💰 This is possible because the smart contract holds reserves of both assets and has a price function based on the ratio of the reserves. Liquidity providers are issued a token that represents their share of the reserves and fees...

👛 Multisig Wallet Challenge
👩👩👧👧 Using a smart contract as a wallet we can secure assets by requiring multiple accounts to "vote" on transactions. The contract will keep track of transactions in an array of structs and owners will confirm or reject each one. Any transaction with enough confirmations can "execute".
