dApp Code Review and Gas Optimization for Existing Projects
Structured consultation on decentralized application architecture — covering smart contract design, frontend integration, and deployment across live networks.
Price covers a single smart contract system up to 800 lines of Solidity and one frontend repository. Larger codebases are quoted per additional scope after initial intake.

What this covers
When a review makes sense
You built something, it works on testnet, and now you are about to put real money behind it. Or you inherited a codebase from a contractor and have no idea what is actually in there. Or your contract is live and users keep hitting unexpected reverts that you cannot reproduce locally. These are the situations where a structured code review is worth more than another week of solo debugging.
This service is not a formal security audit with a certification at the end. Those cost significantly more and involve a different process. What this is: a senior developer reading your code carefully, running it against edge cases, and giving you a written report with specific findings and suggested fixes.
What gets reviewed
Smart contract logic — reentrancy risks, integer overflow patterns, access control gaps, and event emission completeness. Gas usage — storage reads inside loops, redundant state writes, opportunities to use calldata instead of memory. Frontend integration — how your app handles failed transactions, wrong network detection, and wallet disconnection mid-flow.
We also look at your test coverage. A contract with 40 tests that all test the happy path is not well-tested. We check whether your tests actually exercise the conditions that would cause problems in production.
What you receive
A written report organized by severity: critical issues that should be fixed before any mainnet deployment, moderate issues that create friction or cost, and minor suggestions that are worth considering but not urgent. For each finding, there is a description of the problem, an example of how it could manifest, and a concrete suggestion for fixing it.
The report is written for developers, not executives. No inflated risk scores, no vague recommendations about best practices.
Consultation structure
Each stage builds on the previous — sequence matters here.
Review process stages
-
Day 1-2 — Codebase intake. You share your repository, deployment addresses, and any context about known issues. We run the test suite and note what passes, what fails, and what is not tested at all.
-
Day 3-5 — Manual review. Line-by-line reading of contracts, cross-referencing with known vulnerability patterns. Frontend integration review for wallet handling and transaction lifecycle management.
-
Day 6 — Gas profiling. We deploy to a local fork and run gas reports on main contract functions. Identify the top optimization opportunities by actual cost, not guesswork.
-
Day 7 — Report delivery. Written findings document with severity ratings and fix suggestions. Followed by a one-hour call to walk through the report and answer questions.
Scope definition
Identify what you're building and where the architecture currently stands.
Technical review
Walk through contract logic, data flow, and integration points with the frontend.
Recommendations
Specific changes, tools, and patterns with written notes sent after the session.
Schedule a session
Sessions run 60–90 minutes over video call. Describe your project briefly and a specific question you want answered — that keeps the session focused rather than exploratory.
