speedrun ethereum learn solidity development through interactive challenges connect wallet learn how to build on ethereum the superpowers and the gotchas start building on ethereum challenge 0 tokenization ai ready create a unique token to learn the basics of ️ scaffold eth 2 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 quest challenge 1 crowdfunding ai ready 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 the users only have to trust the code not each other quest challenge 2 token vendor ai ready smart contracts are kind of like always on vending machines that anyone can access let s make a decentralized digital currency an erc20 token 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 quest challenge 3 dice game ai ready randomness is tricky on a public deterministic blockchain the block hash is an easy to use but very weak form of randomness in this challenge you will take advantage of a dice game contract by predicting the randomness in order to only roll winning dice quest challenge 4 build a dex ai ready 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 quest challenge 5 oracles ai ready build three powerful oracle systems bringing real world data on chain level up from simple whitelist oracles to staking based systems and finally to optimistic oracles with challenge periods ️ learn crucial security trade offs while implementing dispute resolution and economic incentives quest challenge 6 over collateralized lending ai ready build your own lending and borrowing platform let s write a contract that takes collateral and lets you borrow other assets against the value of the collateral what happens when the collateral changes in value we will be able to borrow more if it is higher or if it is lower we will also build a system for liquidating the debt position quest challenge 7 stablecoins ai ready build your own decentralized stablecoin let s write a contract that takes collateral and issues myusd tokens based on the value of the collateral what happens when the collateral changes in value if it is higher we will be able to borrow more tokens if it is lower we will also build a system for liquidating the myusd quest challenge 8 prediction markets ai ready build a prediction market where users can create questions about future outcomes for others to bet on users can also participate in existing markets to speculate on event results outcome shares can be traded with prices adjusting dynamically based on market belief this is possible because the smart contract acts as an automated market maker like in the dex challenge and adjusts odds based on supply and demand quest challenge 9 zk voting ai ready build your own decentralized voting system using zero knowledge proofs let s write a contract that allows users to vote on a topic and the results will be computed off chain using zero knowledge proofs quest eth tech tree check this advanced solidity challenges to test your ethereum dev skills join capture the flag join our ctf game and hack your way through 12 smart contract challenges start solidity course solidity guides built with at buidlguidl
