Blockchain Development Company in London
Europe's largest fintech market with a 5-hour timezone overlap with Pakistan, post-Brexit appetite for cost-efficient nearshore-quality engineering, and the strictest regulated-software bar outside the US.
London blockchain work runs through the FCA sandbox or doesn't run at all
FCA's regulatory sandbox is the only realistic path to a UK-launched blockchain financial product. We've helped two clients through cohort acceptance, what works is presenting smart-contract code with formal-verification reports, not just unit tests. Foundry + Certora is the stack the regulators take seriously.
Local context
MLR 2017 amendments require crypto-asset firms to register with the FCA before serving UK customers. We design contract architecture with the registration pathway in mind.
Blockchain Development pricing in London vs offshore

Frequently asked by London buyers
How do you handle the timezone gap between London and your team?
We have 4 hours of solid afternoon overlap between Pakistan and London. Most clients run a daily standup at the start of their morning and an end-of-day async update on Slack. For United Kingdom clients we also adjust release windows to local business hours so deployments don't surprise the on-call team.
What's your contracting model for United Kingdom clients?
We run paid 2-week discovery sprints to lock scope, then either fixed-price for tight specs or T&M with a written cap and weekly burn updates. Contracts are governed by English law, with arbitration clauses we'll explain on the first call.
Can you sign an NDA before the first call?
Yes. Send your standard mutual NDA to [email protected] and we'll counter-sign within 24 hours. We don't push our own template unless you don't have one.
Who owns the code at the end of the engagement?
You do, unconditionally. Source code, design files, signing keys, App Store / Play Store accounts: all in your name from week one, transferred at completion if any are temporarily ours during the build.
