How an audit works

A clear, four-stage process. No black boxes.

From kickoff to final report, you know exactly what we're doing, when, and what you'll receive at every stage.

Scoping & Kick-off

We review your codebase, confirm complexity, fix the scope in writing, and assign your senior lead.

Day 1-2

Manual Review

Line-by-line review by senior auditors plus static analysis, fuzz testing and adversarial scenarios.

Day 3-14

Preliminary Report

Findings shared with severity ratings, recommended fixes and a live call to walk you through every issue.

Day 14-16

Fix Review & Final Report

We review your patches, verify each fix and issue the final PDF report — published to our public GitHub on request.

Day 17-21

Selected case studies

Real protocols, real findings, published reports.

Every audit ends with a published PDF on our public GitHub. Here are three recent ones we're proud of.

DEX • Avalanche

Swapsicle

Two-round audit of Swapsicle's AMM and concentrated-liquidity contracts. We delivered an initial report, then re-audited their fixes and published the revised final PDF — both versions are on our public GitHub.

L1 Protocol • Sophia

Æternity Protocol

Full smart contract security review of Æternity Protocol's contracts. The client, a sceptical Sophia-language project, told Trustpilot we were "the one needle in a haystack" — they'd struggled to find auditors with deep non-Solidity expertise.

Prediction Market • NEAR

Pulse Markets

Security assessment of Pulse Markets' prediction-market contracts on NEAR Protocol. Final report published publicly so the Pulse community could independently verify the scope and findings.

"The ONE Needle in a Haystack"

I was sceptical to begin with, but once Joel got in touch we had several exchanges and he convinced me to try Vibranium for a Typescript audit. In a matter of days I was contacted by the team and invited for a call to go through the vulnerabilities.

Nikola Stojanow • BG • Apr 2024

★★★★★

"Excellent service"

Was quite skeptical at first until we started the process of auditing our smart contracts which were written in Sophia. We received a detailed PDF of the vulnerabilities, suggested fixes and more. Communication was seamless, too.

Papi Chuks • GB • Aug 2024

★★★★★

"Fantastic to work with"

The team over at Vibranium was fantastic to work with. All questions we had were answered in a very timely manner as well as insights to our developers on code that needed minor adjustments. I would absolutely recommend them.

Bryan, Swapsicle • US • Oct 2023

★★★★★

"Proactive and professional"

Great communication and a proactive approach. Had many fruitful discussions. Audit on schedule and on-point — also walked us through aspects of it.

Silver • EE • Oct 2023

★★★★★

"Highly recommended"

Their quick turnaround time was impressive, especially considering the depth of the audit. Their team worked efficiently without compromising the quality of their assessment — the timely delivery allowed us to implement the necessary changes promptly.

Ishola • GB • Aug 2023

★★★★★

"Professionals in the business"

Professionals in the business. Always clear process, high level of expertise. It is a pleasure to work with them.

Albina Volchenko • UA • Sep 2023

Vibranium Updraft

Free Solidity security mini-course

Six short lessons. Real attack patterns, real fixes. Built for protocol engineers shipping to mainnet.

LESSON 01

Reentrancy — classic, read-only and cross-function

The full pattern family, why checks-effects-interactions is necessary but not sufficient.

LESSON 02

Access control mistakes that cost millions

Missing modifiers, role-renouncement traps, init-function reentry, uninitialised proxies.

LESSON 03

Oracle integrity and price manipulation

Spot vs TWAP, flash-loan attacks, stale-price defence, circuit breakers.

LESSON 04

Signature replay and permit pitfalls

EIP-712 done right, nonce hygiene, cross-chain replay, ERC-2612 edge cases.

LESSON 05

Upgradeability without footguns

UUPS vs Transparent, storage-layout safety, init-locks and timelocks that work.

LESSON 06

Invariant testing and fuzzing in Foundry

Writing economic invariants that catch what unit tests miss. Templates included.
