WHAT OUR CLIENTS SAY

Lux | Founder of Origami Finance logo

“A lot of projects just want a rubber-stamped audit report and that's not what SBSecurity is all about. SB's background in audit competitions is evident in their speed, persistence, and attention to detail. The auditors have strong opinions on how code should be implemented and know what they are talking about. They are not afraid to dive into new things to bring new insights to an audit.”

Lux | Founder of Origami Finance

Ozzy | Founder of RootsFi logo

“SB Security is a great auditing firm that will, unlike other auditors, ask a lot of questions to understand the smart contracts intention and will quickly point out flaws that don't look to obvious at first. They are quick and precise, and even after audits, very quick to respond and engage with their clients long term via socials and directly via DM.”

FAQ

How long does a smart contract audit take?

A typical engagement runs one to three weeks, depending on codebase size and complexity. We can usually kick off a new audit within 24 hours of agreed scope, and most DeFi protocols of 1,500–4,000 SLOC fit comfortably in a two-week window. We share an exact timeline during the pre-audit scoping call.

Which blockchains and languages do you audit?

We audit everything. Solidity, Rust, Cairo, Move — across EVM (Ethereum, Arbitrum, Base, Optimism, Polygon, BNB Chain, Berachain, Hyperliquid) and non-EVM (Solana, Aptos, Sui, Stellar). We are an official auditing partner of Starknet (Cairo) and have secured one of the top protocols on Move. Whatever your stack, we have shipped a report on it.

How is pricing determined?

Audit pricing is driven by code size, complexity, and the number of auditors required. We give a fixed quote after reviewing your repository — no hourly billing, no surprise overruns. Reach out via Telegram with your repo and target start date and we will return a quote within 24 hours.

What does the audit deliverable include?

You get a full PDF report with every finding categorized by severity (Critical / High / Medium / Low / Informational), a clear proof-of-concept where applicable, and concrete remediation guidance. Once fixes land, we run a free fix review and publish the final report to our public GitHub.

Do you offer post-audit support and re-audits?

Yes. Every engagement includes a fix-review pass where we validate every patch against the original finding. Beyond that we offer an ongoing security partnership — pre-deployment checks for new features, mitigation reviews, and a direct line to the auditing team whenever your protocol changes.
