We’re a team of engineers, product architects, and builders focused on helping Web3 teams launch faster and build smarter.
No over-engineering. No vague buzzwords. No code we’d be ashamed to show.

 

We work with startups, protocols, and funds to:
• launch lean and honest MVPs
• architect scalable systems (only when needed)
• develop secure smart contracts and infrastructure
• guide technical decisions that actually make sense

 

What we do:

• Smart Contracts & Audit-Ready Code
We write clean, modular, secured contracts — with real-world gas costs, audits, and usage in mind.
• Blockchain Architecture
We help design and structure everything from tokenomics to protocol-layer logic and off-chain orchestration.
• Lean Web3 MVPs
We don’t build what’s trendy. We build what’s essential — to get your product out and tested fast.
• Consulting & Product Thinking
RedDuck isn’t just a coding partner. We challenge assumptions, ask real questions, and propose smarter paths.

 

How we work:

• We don’t over-engineer
• We communicate honestly — even if it’s not what you want to hear
• We move fast, without breaking fundamentals
• We think in outcomes, not just features
• We care more about principles than trends

• We work closely with Web3 founders, product teams, and protocol builders. 

• Our workflow is pragmatic and collaborative — from architecture calls to rapid implementation.
• Based in Europe, operating globally
• We join projects early and stay hands-on
• Communication is direct, structured, and fast
• We’re flexible: from short advisory sprints to full development cycles
