Join blockchain engineers and decentralized systems architects as we explore real-world implementations. These aren't basic overviews — we dig into the technical challenges you'll actually face when building on decentralized networks.
We schedule these deep-dive sessions based on what the community is actually building. Real problems, practical solutions.
Walk through common vulnerabilities we've seen in production contracts. We'll review actual exploit cases and demonstrate prevention strategies that work in practice.
Building reliable connections to existing DeFi protocols. This covers rate limiting, error handling, and the edge cases that documentation doesn't mention.
Practical comparison of rollup technologies for different use cases. We'll deploy the same application across multiple L2s and measure the real differences.
Henrik spent three years building infrastructure for a DeFi protocol that processes over $2 billion in transactions. Before that, he worked on distributed systems at a fintech company.
His sessions focus on the problems you won't find in tutorials — like handling network congestion, managing gas costs during market volatility, and debugging failed transactions across multiple chains.
Current Project: Leading backend development for a cross-chain liquidity protocol
Previous Experience: Senior blockchain engineer at three different startups, all still operating
We've tested different formats over the past two years. This combination gives you the most practical value for your time investment.
We examine real codebases from production applications. You'll see how experienced developers structure their projects and handle common challenges.
Bring your current challenges. We dedicate time in each session to work through specific technical issues participants are facing in their projects.
We measure actual performance metrics — transaction speeds, gas consumption, network costs. Numbers matter more than theoretical discussions.
Sessions start in March 2025. We keep groups small — usually 15-20 people — so everyone gets time to ask specific questions about their projects.
