👩‍🎤 Builder on Ethereum, BuidlGuidl Founder.

I build lots of random things and try to teach other developers too!

Austin Griffith

In this session, we’re going to dive into Scaffold-ETH v2, a toolkit we built to make developing on Ethereum way easier. We’ll take a look at how it works, why it’s super useful for quickly spinning up projects, and how we can use it to tinker with smart contracts and hook up the frontend. 

⚙️ Scaffold-ETH 2 is built using NextJS, RainbowKit, Foundry/Hardhat, Wagmi, Viem, and Typescript.

Whether you’re new or experienced, we’ll get you to SpeedRunEthereum!

Classroom B

Austin Griffith –  Intro to Scaffold-ETH 2 and SpeedRunEthereum!

**Afternoon Workshop (1:15 - 2:15 pm)**

Accelerate your Ethereum skills in this rapid-fire workshop! You’ll build five dApp prototypes on Ethereum using Scaffold-ETH 2 and its powerful extension starter kits

We’ll cover key concepts in smart contracts, front-end dApp development, and how Scaffold-ETH 2 streamlines the process with ready to use state-of-the-art tools. 

This session is ideal for beginners looking to gain hands-on experience quickly.

BuidlGuidl - Build Your first five apps on Ethereum

 You are a builder, go to speedrun ethereum to learn how to build on ethereum. This will help you with your first five apps. We're going to speedrun the speedrun today. I've written a bunch of code. This will probably be a little less code writing and more just like going through the tutorials and talking about some of the aha moments you have along the way. Just to like zoom all the way out, we are the build guild. We are focused on developer education and tooling. Our main tool of choice is scaffold ETH and we use that to build a bunch of things. But that is also the heart of Speedrun Ethereum, which is our curriculum. And we're going around the world teaching people how to build on Ethereum, and anybody can just go to Speedrun Ethereum and get started today. And we're going to kind of just speedrun the speedrun today. I'm going to go through the challenges and just kind of talk through the kind of the aha moments you'll have. But hopefully you can go home and speed run Ethereum on your own time and really kind of go through this at your own pace. But I'm going to go through it quickly just to kind of cover like, oh, here's the stuff to look out for, basically. Let's do just real quick, if you guys could give me a show of hands, how many of you have deployed a contract on main net before? Oh, yeah, we have five or six main net deploys. How many of you have deployed on an L2? Actually less, I think, right? Less people? Okay, we're going to change that today for sure. We have to get you ready for that. I deployed one to base earlier and someone attacked it and stole my money. It was pretty fun. How many of you are software developers? Okay. Those. Look at those. I would say that was almost all the hands. I just got goosebumps. I'm excited. This is awesome. I'm going to do the speed run. Probably 20, 30 minutes, I'm going to speed run the speed run, and then I'm going to hand it off to Etta and she's going to do I think like an NFT build, right? Cool. Awesome. Okay.

BuidlGuidl CTF - Capture the Flag game

**Morning Workshop (10-11:45 am)**

Jump into Ethereum development with a hands-on introduction to Scaffold-ETH 2 and its powerful extension system! 

We'll show you how to set up your development environment and how to use state-of-the-art tools to deploy live apps that people can use, while introducing you to the essentials of blockchain development.

No prior experience needed—perfect for those eager to start building in Web3. Let’s get your first Ethereum dApp live!

BuidlGuidl - Intro to Ethereum Development, Build & Deploy your first dApp

We will tinker with Solidity, build out a frontend, deploy the contract, and ship an app onchain—all in 80 minutes with state-of-the-art tooling.

Build and deploy an onchain app in 80 minutes!

0xPARC community developers will present apps built on top of the Programmable Cryptography stack, including FROGCRYPTO, Zupass, Meerkat, and many more. This session will also include a live workshop where you can learn to build your own, and there may be a cryptographic prize for those who complete the challenges…
