Smart contract audit services for Solidity and Rust code
Smart contract audit services review your on-chain code line by line before money is at stake. Omeiro combines manual review with automated analysis of Solidity and Rust contracts, hunting for reentrancy bugs, flash loan exploits and integer overflows.
Deployed contracts are hard to change, so mistakes are costly. An audit reduces risk but cannot remove it entirely.
Smart contract audit: what to hand over before review starts
A smart contract audit is limited by the quality of what is handed over. Provide the repository, documentation of intended behaviour, the test suite, deployment scripts and details of external contracts such as oracles or token standards. Auditors compare the code with the intended design, so a short spec saves time and catches mismatches. Contracts that call other protocols, use upgradeable proxies or hold large balances deserve extra attention to access control and upgrade paths.
Findings are rated by impact and likelihood, with a recommended change for each. A smart contract audit is a review at one point in time, so any later code change should be reviewed again before deployment. Premium includes a re-audit after fixes. Tests, on-chain monitoring and an upgrade or pause plan remain sensible additions, because an audit lowers risk without removing the need for operational safeguards.

FAQ
Smart Contract Audit Services: common questions

How long does web3 security audit take?
Delivery depends on the package: Basic 5-day delivery; Standard 10-day delivery; Premium 18-day delivery.
What is included in the Basic Package?
The Basic Package includes: Up to 300 lines of contract code reviewed. Higher packages add more scope, revisions and support.
Can I get a custom solidity smart contract auditing package?
Yes. If none of the packages fits, use the custom package form on this page to describe what you need, and our team sends you a fixed price.
Does an audit guarantee safety?
No, it lowers risk but cannot prove a contract free of bugs.
Which chains are supported?
Solidity and Rust contracts are covered, and we confirm your chain.
Should the code be finished?
Yes, freeze the code before auditing.
What if my code is larger than the tier?
Choose a higher tier or ask us before ordering.
What is reentrancy and how is it prevented?
Reentrancy happens when a contract calls an external address that calls back before the first call finishes, letting state be abused. It is prevented by updating state before external calls and using reentrancy guards.
What is a flash loan attack?
Attackers borrow a large sum within one transaction, use it to manipulate a price or voting power, then repay it. Contracts that rely on a single spot price are especially exposed.
