Learn Solidity with our
Web3 Developer Course

Yes! Speedrun Ethereum is completely free. Our mission is to make Web3 development accessible to everyone. You'll get access to all challenges, guides, and community support at no cost.

Basic programming knowledge is helpful but not required. We start with the fundamentals and build up gradually. If you're new to programming, we recommend complementing the course with some JavaScript basics material.

Most students complete the core curriculum in 4–8 weeks, spending 5–10 hours per week. You can go at your own pace, the challenges remain available indefinitely. If you really want to speedrun it, you might finish in about 1 week (~40 hours). If you're already a senior developer with some Solidity experience, it might take only ~20 hours in total.

You'll build a public portfolio of completed challenges and projects on the blockchain. This serves as proof of your skills to potential employers and is often more valuable than a traditional certificate. You will also receive a BuidlGuidl Batch NFT if you complete Speedrun Ethereum and successfully finish one of our batch programs.

Start by building something small that actually works, instead of reading theory first. Speedrun Ethereum is a free curriculum that opens with the Tokenization challenge, where you compile and deploy your first smart contract, mint an NFT, and ship a working app. Basic programming knowledge helps but is not required, because the curriculum starts with the fundamentals and builds up gradually. Each challenge is built around one key aha moment about how Ethereum really works.

Move into the advanced half of the Speedrun Ethereum roadmap. Once you have the fundamentals covered through Tokenization, Crowdfunding, Token Vendor and the Dice Game, the curriculum moves on to decentralized exchange development, over-collateralized lending and stablecoins, prediction markets and oracles, and a privacy-preserving voting dApp built with zero-knowledge proofs. Each one is a complete build rather than an exercise, and each completed challenge becomes part of your on-chain, verifiable builder profile.

Speedrun Ethereum is a free, guided course from BuidlGuidl. It is a structured learning path that runs from your first smart contract to advanced Web3 concepts, taught through hands-on challenges rather than lectures. You build with Scaffold-ETH 2, a developer toolkit that gives you a local blockchain, a frontend and debugging tools, so what you write is a production-grade dApp rather than a toy example.

Follow the Speedrun Ethereum roadmap in order. It starts with an NFT in the Tokenization challenge, moves through DeFi primitives with a crowdfunding app and a token vendor, covers randomness and security in the Dice Game, then builds a decentralized exchange, an over-collateralized lending platform, a stablecoin, a prediction market with oracles, and a privacy-preserving voting dApp. Every challenge is a complete build that becomes part of your on-chain portfolio.
