Happy-path tests confirm what you already believe; they find nothing
We define the protocol's invariants up front and fuzz against them, so the suite searches for the failure instead of the success
The first real edge case then shows up in CI, not on mainnet where it is expensive
Access control scattered across modifiers means nobody can answer who can do what
We define roles, timelocks and emergency powers as a documented model before implementation, so integrators and auditors can read it in one place
That model is the first thing an integrator reads before they trust you with their users' funds
Unnecessary storage writes are a tax your users pay on every interaction
Hot paths are profiled and optimised during the build, and the tradeoffs are written down rather than assumed
Where a cheaper structure would cost clarity or safety, we say so instead of quietly taking it

Solidity for Ethereum and the EVM L2s, Rust for Solana-style environments, and Vyper where a project already standardised on it. The chain is usually decided by where your liquidity and users already are — we treat it as a constraint on the design rather than a preference.
We do, and the test suite ships with the contracts. That means Foundry unit tests, fork tests against live state where it matters, and invariant tests that fuzz the properties the protocol must never violate. You get the suite, so your team can keep extending it after handoff.
Yes, and we will also tell you when you shouldn't. Upgradeability buys flexibility and costs trust — every proxy is an admin key someone has to justify to users and integrators. Where it makes sense we implement it with safe storage layouts, timelocks and a documented upgrade runbook; where it doesn't, immutable contracts with a clean migration path are the better answer.
Yes. A contract review is a common starting point. We read the deployed code and the tests, map the permission model and trust assumptions, run our own invariant and fuzz suite against it, and come back with findings ranked by real-world impact rather than by severity labels. That is not a substitute for an independent audit — it is what makes the audit worth what you pay for it.
It scales with mechanics, not with line count. A token with vesting is a small, well-understood piece of work; a staking system with governance and oracle dependencies is a different order of complexity. Every engagement starts with a scoping phase that produces a fixed scope and a fixed estimate before production begins.
