Solution
Blockchain&Web3
Smart contracts, wallets and on-chain apps, only when decentralised trust genuinely earns its place.

We build tested smart contracts, wallet integrations and on-chain applications in Solidity and related tooling. We start by asking whether a blockchain is the right answer, and we will say so if it is not.
What we do
Smart contract development
Solidity contracts written for clarity and safety, with a full test suite and a path to independent audit before any mainnet deployment.
Wallet and on-chain integration
Connect wallets, sign transactions and read on-chain state from your app, with clear handling of failed and pending transactions.
Architecture review
An honest assessment of whether on-chain, off-chain or a hybrid best fits your case, including cost and custody trade-offs.
Where it fits
Use cases.
Smart contract design and audit
We write Solidity contracts with thorough tests, then review them adversarially for common failure modes. Where a contract already exists, we audit it and report findings plainly.
Wallet-connected application
We build the interface and backend that let users connect a wallet, sign actions and see on-chain state clearly. The experience stays understandable for people who are new to Web3.
On-chain issuance
We handle minting and managing tokens, certificates or records with the right access controls. Off-chain data and metadata are kept in step with what lives on the chain.
Capabilities
Everything it covers.
- Solidity smart contract development with full test coverage
- Independent contract review and security audit
- Wallet connection and transaction signing flows
- Gas-aware design to keep transaction costs sensible
- Testnet deployment and staged rollout before mainnet
- Off-chain indexing so your app reads chain data quickly
- Clear interfaces for users unfamiliar with Web3
- Key management and access-control patterns done carefully
Typical timeline
A contract with audit and a working front end generally takes six to twelve weeks. Audit-only engagements are shorter and scoped to the codebase.
How scope works
We only recommend blockchain when it genuinely fits. If a database serves you better, we will say so rather than add complexity and cost you do not need.

How we work
Four steps, no surprises.
Scope
We map the goal, the constraints and the risks, and agree a fixed brief before anything starts.
Design
Interfaces, architecture and the plan, reviewed with you before a line of code is written.
Build
Type-safe, tested delivery in short increments you can see and steer.
Launch & care
We ship, hand over everything, and keep it running if you want us to.

Questions
Good to know.
How long does Blockchain & Web3 take?
Timelines depend on scope. Most engagements run from a few weeks to a few months, and you get a firm estimate after a short scoping call.
How is it priced?
From £14,000 is an indicative starting point. Every project is quoted to the scope we agree, with no surprises later.
Do we own what you build?
Yes. You own the source code, the design files and the accounts. There is no lock-in.
Do you maintain it after launch?
We can. Hosting, monitoring and updates are available as an ongoing plan, or we hand over cleanly to your team.
