Crypto Wallet Development in London

Wallet software for London organisations. The first decision determines everything else and much of your regulatory position: whether users hold their own keys, or you hold them on their behalf — custody is a fundamentally different business with obligations attached.

Why this comes up

The problem

The product needs users to hold or transact digital assets, and whether to take custody has not been decided or assessed.

What you get

What we deliver

  • The custody question settled first, with regulatory advice where you would hold assets
  • Key generation and storage designed to established practice, not improvised
  • Recovery designed realistically, since lost keys mean permanently lost assets
  • Transaction signing with clear confirmation of what is being approved
  • Security review by people independent of the build
  • Honest communication with users about what happens if they lose access

Want this scoped for your business in London?

Thirty minutes, no charge, no sales script. You leave with a written summary of what crypto wallet development would actually involve — whether or not you use us.

Crypto Wallet Development in London — common questions

Custodial or non-custodial?
It is the defining decision. Non-custodial keeps users responsible for their own keys and keeps you out of holding client assets. Custodial is easier for users and likely brings regulatory obligations — including registration requirements. Take advice before choosing.
What are the obligations if we hold assets?
Firms carrying on cryptoasset activities in the UK face registration and anti-money-laundering requirements, and the regime continues to develop. This is a question for regulatory counsel at the outset, because it can determine whether the product is viable.
How should recovery work?
Deliberately, and communicated plainly. Seed phrases lose people their assets constantly; social recovery and multi-signature approaches trade some decentralisation for recoverability. Whatever you choose, users must understand it before they need it.
Who should review the security?
Someone independent of the build, with relevant experience in this specific area. Wallet code holds value directly, which makes it a standing target, and internal review by the people who wrote it reliably finds a fraction of what an outside specialist will. Budget for that review as part of the build cost rather than as an optional extra afterwards.
Do you work with businesses across Greater London?
Yes. We are based in Leicester, United Kingdom and work with clients throughout London, including London and the surrounding Greater London area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
What kind of London businesses do you usually work with?
Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates. Beyond that we work across Financial Services, Professional Services, Technology, Media, Hospitality and Retail.
Do you cover the areas around London?
Yes — we work throughout London, including Reading, Milton Keynes, Cambridge, Brighton. London is an urban area of roughly 9,000,000+, and we take on work across the wider Greater London region rather than the city boundary alone.
