Consulting and engineering for teams shipping crypto-native infrastructure.
We design and ship the engineering work behind agent-payable APIs, cross-chain token launches, and the kind of software discipline that keeps an LLM-assisted codebase maintainable. Consulting, engineering, and workshops, in English or German.
Three positions we do not move on.
Boutique consulting works only if it stands for something. These are the three commitments every Hodlhaus engagement is built on.
01
Engineering and advice are the same product
We ship code, not slide decks. Every recommendation arrives with the reasoning written down, so a CTO can defend the choice in a board meeting six months later — and so the engineers who execute it know exactly which assumptions to revisit when the world changes.
02
We bring an opinion
Vendor-neutral advice is expensive vendor-neutral mush. If we think x402 over USDC on an L2 is the right rail for your traffic, we say so — and we tell you why we ruled the alternatives out. The point of hiring expertise is to get an actual opinion.
03
We tell you in week one
Most engagements start with a paid two-week diagnostic. If your idea has a fatal flaw, you find out before you spend six months discovering it the hard way. We would rather end a project early than bill through one we no longer believe in.
What we do - Three practice areas, three ways to engage.
We go deep on three problems and we deliver the work three ways: consulting, engineering, or a workshop. Mix and match.
Have a problem worth our time?
We work with a small number of clients per quarter. If you are launching a token across chains, building an agent-payable API, or trying to ship safer code with AI tools — tell us about it.
