Smart contract development
Your product’s rules deserve more than a quick deployment. We help you define them, turn them into contracts and connect them to an app people can use.
Start with the rules.
Before writing a contract, we work through what your product should do. Who can move funds? Which actions need permission? What should happen when a transaction fails? Those decisions shape the implementation and the interface around it.
We build smart contracts for tokens, product transactions and DeFi workflows. The scope can be a focused contract or the contract layer of a complete Web3 product. If you already have an implementation, we start by understanding what needs to change.
Tokens and launches
Define supply, distribution and administrative permissions, then connect the contract to the launch experience.
Product transactions
Translate actions such as entering a raffle or settling a game into explicit rules and testable behaviour.
DeFi contracts
Work through deposits, withdrawals, permissions and integrations as part of the wider movement of funds.
Know what you’re getting.
We agree on the deliverables before implementation. A useful handover includes the source code, tests, deployment instructions and an explanation of the decisions another engineer will need to understand.
Testing should cover the rules that must always hold, as well as expected user actions. We also work through unsuccessful transactions, access restrictions and boundary conditions. The test plan depends on what the contracts control and the integrations they rely on.
- A clear specification of the contract’s behaviour and permissions
- Implementation with tests for the agreed product rules
- Deployment and verification instructions
- Documentation for the team maintaining the product
Make room for review.
Audit preparation is part of engineering work. We organize the code and documentation so an independent reviewer can understand the scope. If a separate audit is planned, allow time to address findings and review changes before launch.
An audit is a separate engagement and does not guarantee that software is free of bugs. We agree on who handles external review and what needs to be ready before funds or users depend on the contracts.
Bring the product with you.
Contracts rarely stand alone. A wallet prompt, a pending transaction and a failed request all affect the experience around them. We can work alongside your existing app team or take on the connected dApp as part of the same project.
A short brief is enough to start. Tell us what the product does, whether there is existing code, the chain you are considering and any launch constraints. We will use that to discuss scope and the next useful step.
A few common questions.
Can you work with an existing codebase?
Yes. Share the current scope and the changes you need. We review the code and its assumptions before agreeing on implementation work.
Does development include an independent audit?
We can prepare the code and help address findings. An independent audit has its own scope, reviewer and budget, which we agree before scheduling a launch.
Can you also build the frontend?
Yes. Our dApp development work includes product design, wallet connections, frontend and backend development.
