Smart Contract Development & Audit

A review combining manual inspection by engineers who did not write the code with automated tooling — static analysis in Slither, property-based fuzzing in Echidna or Foundry, and formal verification of the stated invariants. Findings are graded by severity, tracked to closure and retested after fixes. We also recommend an independent external audit before mainnet and manage that process alongside our own review.

Yes. The first step is reconstructing the invariants — what must always be true about balances, access control and accounting — because those are usually undocumented. From there we run static analysis, fuzzing and fork tests against production state, then deliver a severity-graded findings report with reproduction steps, plus remediation code where you want us to write the fixes rather than describe them.

Upgradeability is a design decision made before deployment, not after. Where governance requires it we use UUPS, transparent proxy or diamond patterns with a timelock and a multi-signature owner, so an upgrade is announced, delayed and reviewable rather than instant. Where immutability is the stronger property we deploy without an upgrade path and version by migration. Storage layouts are checked against the previous implementation every time.

Through storage layout — packing variables into shared slots, avoiding redundant writes, and using calldata rather than memory for read-only arguments — plus removing repeated state reads inside loops. Assembly is used sparingly and only where the saving is measurable, with the equivalent high-level logic documented beside it. Gas snapshots run in continuous integration, so a change that increases cost is visible in the pull request.
