Senior Blockchain & AI studio. Amsterdam HQ, engineering in Prishtina. We turn ambitious ideas into production-grade products — audited, on mainnet, in 8–12 weeks.
Trusted by founders, funds & protocol teams · EU / US
> We don't try to be everything. We pick the few things we are excellent at and ship them at a level you can hand to your investors and your auditors.
Talk_to_partner ↗From whitepaper to mainnet in 8–12 weeks. Smart contracts, indexers, dApps and infra — audited and production-ready.
Agents, RAG pipelines and multimodal copilots built on the Claude, OpenAI and open-source model stack.
Type-safe, accessible, fast. We build web and mobile products that compound — not prototypes you have to throw away.
Internal audits, threat models and continuous review for Solidity, infra and AI agent surfaces.
Strategy, brand systems and product design built around the actual user journey — not the demo screenshot.
Tokenomics modelling, vesting, liquidity bootstrapping and treasury ops for serious teams.
> Four operating principles. They aren't aspirational. We turn down work that doesn't fit them.
Every engineer on your project has shipped a real product. No 'platform team' to babysit. No juniors learning on your timeline.
You see working software, not slides. If we cannot demo it, we have not built it. Your investors should be able to read our changelog.
Slither and Foundry invariants run on every commit. Pre-audit hardening built into the cadence — not bolted on at week 12.
We shape the engagement before we sign anything. You get a timeline you can plan around — and a number you can put in front of a board.

> No 12-week discovery deck. No "platform team". Senior engineers shipping demoable progress on a tight, two-week cadence.
01
One-week paid sprint. We map the problem, talk to your users, and write the spec the team will actually build against.
02
Tech choices, threat model, infra cost envelope, and a build plan with weekly demoable milestones.
03
A small senior squad — staff engineer, designer, ML or chain specialist as needed — shipping on a 2-week cadence.
04
We don't disappear at launch. We stay on as your fractional engineering team, on retainer, until you've hired your own.

"Blocify shipped our intent-router on Base in eleven weeks. Our previous agency had been trying for six months. The audit came back with two informational findings."

"The most senior team we've worked with. They wrote the spec we should have written, then built it."

"We hired Blocify for an MVP and ended up keeping them as our fractional engineering team for a year. They earned it."

> No PR fluff. Direct answers to the questions we get on every first call.
> Most engagements kick off within two weeks of the first call. We always run a paid one-week discovery sprint before any larger commitment so neither side is guessing.
> Three to five senior people: a staff engineer, a designer, and one or two specialists (smart-contract engineer, ML engineer, or platform engineer) depending on the work. No accounts manager between you and the team.
> Yes — we have done it many times. The constraint is scope, not capability. We will tell you within the discovery sprint whether eight weeks is realistic and exactly what we would cut to fit it.
> Internal review is part of every engagement. For external audits, we work with Spearbit, Trail of Bits and Cantina, and we hand auditors a codebase that has already passed our internal hardening checklist.
> Occasionally, in addition to a reduced cash rate, for early-stage teams we believe in. The default model is fixed-scope cash on a 4-week or 8-week milestone schedule.
> Headquarters in Amsterdam, engineering office in Prishtina, Kosovo. The whole team is on CET ±2h. We meet clients in Amsterdam and run the build out of Prishtina.
> Tell us where you are and where you want to be. We'll come back with a shaped engagement, a fixed timeline, and a price you can plan around.
