Build Real Things with Blockchain Code

Most blockchain courses teach you theory. We put you in front of actual smart contracts from day one. You'll write Solidity, debug Rust, and build working dApps that people can actually use. Our autumn 2025 program starts with zero assumptions about what you know.

Questions People Actually Ask

Before You Start

Do I need programming experience? Not really. We start with basic syntax and move forward from there. You should be comfortable with logic puzzles and willing to spend time debugging.

"What if I've never touched command line?"

During the Program

Classes run twice weekly from September through November 2025. Each session is three hours. Half that time you're coding. The other half we're solving problems together or reviewing what broke in your code.

"How much time outside of class should I expect?"

After You Finish

You'll have a portfolio of working projects. Real contracts deployed on testnets. Documentation you wrote. Code others can fork. That's what hiring managers want to see.

"What happens if I can't find work right away?"

Ongoing Support

Our Discord stays open after graduation. Questions about interviews, technical decisions, or weird errors? Ask. Alumni often help each other more than we do.

"Is there mentorship or just open chat?"

Smart Contracts That Work

First week you deploy an ERC-20 token. It won't do much, but it'll compile and run. Week three you add access controls. Week five you're testing edge cases.

By October you're building a small DeFi protocol. Nothing fancy. Maybe a staking pool or simple DEX. But it works and you understand why.

No one learns Solidity by reading. You learn it by breaking things and fixing them.

Rust for Blockchain

Solana runs Rust. So does Polkadot. Near Protocol too. If you only know Solidity, you're missing opportunities.

Rust is harder. The compiler yells at you constantly. But once your code compiles, it usually works. That matters when you're handling money.

We spend four weeks on Rust basics, then another six building Solana programs. You'll curse the borrow checker. Everyone does.

How We Actually Teach This

Three stages, each building on what came before

1

Foundation Phase

Weeks 1-4 cover blockchain fundamentals. How transactions work. What gas means. Why immutability matters. You'll set up development environments and deploy your first contracts to testnet.

2

Building Phase

Weeks 5-10 you're coding constantly. Each week introduces a new pattern. State management. Event emissions. Inter-contract calls. Security considerations. Your projects get more complex.

3

Portfolio Phase

Weeks 11-14 you choose a capstone project. Something you'd show an employer. We provide feedback. You iterate. Final presentations happen in late November 2025.

Instructor Linnea Bergqvist, lead blockchain developer

Learn from People Who Ship Code

Linnea Bergqvist spent three years building DeFi protocols before teaching here. She's debugged more failed transactions than most people write.

Our instructors work on real projects. They know which patterns scale and which ones create gas nightmares. When something breaks in your code, they've probably seen that exact error before.

Office hours run Monday and Thursday evenings. Bring your bugs. Bring your questions about architecture. We'll figure it out together.

Next Cohort Starts September 2025

Fourteen weeks. Twice weekly sessions. Real projects you'll actually want to show people. Classes fill up by mid-summer, so if you're thinking about it, probably worth reaching out soon.
