Blockchain & Smart Contracts
Smart contract code is deployed into an environment where a mistake is public, permanent and frequently expensive. That changes how it should be written. Less iteration, more review, and testing that assumes someone is actively trying to break it rather than use it. We build contracts and the tooling around them for teams who need the code to be right the first time.

Smart contract development
Contracts written in Solidity, structured for readability and review. Upgrade paths decided deliberately at design time rather than discovered as a problem after deployment.
Token and protocol integration
Working with existing standards and protocols, including the parts of them that are underdocumented. Integration tested against forked mainnet state rather than idealised local conditions.
Adversarial testing and review
Testing from the position of someone trying to extract value: reentrancy, access control, arithmetic, ordering and the assumptions a contract makes about who is calling it.
Wallet and dApp interfaces
The application layer that people actually touch. Transaction states, failure handling and clear feedback, so users know what happened rather than watching a spinner.
How we work
Specify the contract in words first. What it must guarantee, who can do what, and what must never happen. Ambiguity at this stage becomes an exploit later.
Design the trust model. Roles, permissions, upgradeability and admin powers made explicit, because those are what a reviewer will examine first.
Implement narrowly. Smaller surface area, fewer moving parts. Complexity is the thing that gets exploited.
Test adversarially. Unit tests, fork tests and attack scenarios. Nothing is called done because the happy path passes.
Document for whoever inherits it. The guarantees, the assumptions and the admin capabilities, in language a non-author can act on.

Why work with us
We write for review, not for cleverness.
Contract code is read more than it is run. Readable code is auditable code.
Adversarial testing is the default.
Passing the happy path proves nothing about a contract holding real value.
The trust model is explicit.
Admin powers and upgrade paths are documented, not buried, because that is the first thing anyone evaluating you will look for.
