Blockchain & Web3
Blockchain Where It Really Fits
We start by asking whether you need a blockchain at all. If you do, we design the smart contracts, wallets and custody around security from the first line, and list the regulatory questions early so your legal advisers can answer them.
What you get at each stage
Sized to where your product is now, and built so the next stage adds to it rather than starting again.
Idea & validation
Decide whether a blockchain is the right tool
- The blockchain-or-database test, applied to your idea
- Network and token options compared on cost, speed and security
- Regulatory questions listed for your legal advisers
- A costed plan, or a clear recommendation to use a database
MVP & launch
Build contracts and wallets that are hard to break
- Smart contracts built on audited libraries rather than custom code
- Unit, fuzz and invariant testing before any audit
- Wallet and key design with recovery planned in
- Personal data kept off-chain from the start
Growth & scale
Launch carefully and keep watching once live
- An independent audit for contracts that will hold significant value
- Staged release with monitoring and alerts
- Upgrade, pause and incident procedures
- Integration with regulated custody or payment providers
What is included
Do you need a blockchain?
A plain test: who writes to the record, who is trusted to run it, and whether permanence helps or hurts.
Smart contract development
Solidity or Rust contracts written to be tested and audited, with gas costs and upgrades planned.
Security review and audit
Code review and automated analysis, findings ranked by severity and retested, and an independent audit arranged when needed.
Wallets and custody design
Multi-signature approvals, recovery options for lost keys, or integration with a regulated custody provider.
Token design
Token rules people can understand, with a clear purpose beyond fundraising or marketing.
Integration and monitoring
Contracts connected to your app, payments and data, with event monitoring and alerts once live.

Scope it free, then build it
Your MVP brief is the brief
The brief you write in the free MVP builder is what we quote from. It tells us who the product is for, the Must-have features, the main journeys and the budget, so work on Blockchain & Web3 starts from your brief, not a blank page. It fits these stages:
For established companies
New products and ventures, scoped first
Established companies use the same test before committing budget: would a shared, tamper-evident record between several organisations beat the database they already run? Where it would, for example records shared with supply chain partners or loyalty and ticketing tokens, we scope a small pilot with security review, data protection and the regulatory questions covered before anything goes live.
Tell us about your projectQuestions founders ask
Do we actually need a blockchain?
Often not. If one organisation controls all the data, the records hold personal data you may need to correct or erase, or mistakes must be reversed quickly, a database is usually simpler and cheaper. We run that test first and tell you plainly when a database would do the job.
Does our project need FCA authorisation?
It depends on what it does. Issuing, exchanging, holding or promoting cryptoassets can be regulated in the UK, and some activities need FCA authorisation or approval. Check whether your activity is regulated and take legal advice before launch. We map the questions early and work alongside your lawyers, who give the formal advice.
What does a smart contract audit involve?
A line-by-line review of the contract logic, automated analysis and testing against known attack patterns. You get findings ranked by severity, which are fixed and retested. Contracts that will hold significant value should also have an independent audit by a specialist firm, which we arrange.
Who does the blockchain work?
Our own team. We scope the work with you from your brief, keep it tied to your launch plan and deliver it with our engineers, adding vetted specialists where the work needs them: one brief and one point of contact throughout.
