You raised the funds, worked like mad, and now you are almost ready to launch.A hack would destroy everything so you need an audit. But these are extremely expensive and a wrong choice wastes money you cannot afford to lose.*How do I find the best audit partner for my protocol?*I've written this guide based on my years of experience so that any protocol can make an informed decision on who to partner with and how to avoid pitfalls that could ruin everything. # An Audit is not Security One of the worst mistakes a protocol can make is to outsource all security to the audit at the end of the development process. They want to move fast so they iterate with reckless abandon, minimal or no testing and no reflection on the attack surfaces and defensive patterns.If you do this, you will not get an audit report. You will get an obituary.When the code is so fundamentally flawed that the report looks like a book filled with dozens of criticals and highs, there is no fixing it. It requires a full rework from scratch and a new audit. In my experience no team has sufficient R&D or Security budget for this.It is a death sentence.So make security a priority from the start, before you even code the first variable. What follows is a non-exhaustive list of areas that need to be covered before you contact a security company. # Threat Model Once you have written the whitepaper for your protocol, you need to write another paper detailing how hackers can attack it, what the attack surfaces are, and how you plan to protect each of them.This must be done early because it should strongly influence your architecture. Whatever innovation you are trying to create, there are almost always dozens of ways to get from A to B. Each path has its own advantages, disadvantages, exploitation routes and attack surface.Your architecture should be an informed, conscious choice, not a surprise waiting to happen. # Access Control Concentrating all protocol superuser power into one Admin role will put a gigantic bullseye on your protocol and attract every blackhat on the globe.Using a multi-sig is not a sufficient means of defense.A granular access control model with checks and balances is an absolute requirement in 2026\. It is not difficult to implement and it protects you from an entire class of exploits. # Testing Any protocol that does not have a comprehensive testing suite should not be audited. I have refused a protocol spending well over six figures unless they first implemented testing. Not because it makes my work easier, but because I hate writing obituaries. ## Unit Testing This is the basic form of testing and should confirm every expected function flow in the protocol. This is easy to build but only shows that the basic functionality is present and working. ## Fuzz Testing Fuzz testing runs a function many times with randomized inputs inside defined boundaries. It is an excellent way to surface edge cases that developers never considered.The preferred approach is stateful fuzz testing. In this form, the result of each run becomes the starting state for the next. This matters because most serious edge cases only appear after the protocol has already moved into an exotic state. ## Invariant Testing Invariant tests define a property which must always hold given a certain state. There are many ways to implement this, from simple assertions to full formal verification. It is the best way to gain real assurance that your protocol functionAdditionally, it has the advantage that AI cannot easily overfit code to pass invariant testing. Which is an increasing problem with the adaptation of AI coding tools in the development cycle. # Understand What You Are Buying An audit is not a can of Coca-Cola. Different providers sell different combinations of technical expertise, institutional assurance, capacity and reputation.This matters because the best partner is not always the company with the strongest brand, the longest history or the lowest price. ## Large Audit Firms The large traditional audit companies are extremely expensive, but they offer more than just people reading code.You are also buying: - An established process for scoping and delivering the engagement. - Multiple researchers and the possibility of internal escalation. - Project management and organizational capacity. - A recognizable name on the final report. - A signal that may reassure investors, partners and users. If a major investor, launch partner or integration requires a respected audit name, then the discussion is not purely about security. The report also serves a commercial and institutional purpose. Paying the brand premium can be entirely rational.But the firm’s track record means nothing if the researchers assigned to your project do not have the relevant experience.A logo cannot find vulnerabilities. People do. ## Boutique Firms Smaller firms often sit between the traditional firms and the independent researcher. They may have less brand recognition but deeper expertise in a protocol category.This can be an excellent choice if their specialization matches your code.Make sure the people who actually review your code are the ones who have that expertise. ## Independent Researchers An independent researcher removes much of the assignment uncertainty.You speak directly with the researcher, discuss the threat model without layers of project management and know exactly whose judgment you are buying.Because there is less organizational overhead, more of the fee can go directly toward research time. For a focused scope, this can provide excellent technical value without requiring the budget of a larger engagement.The trade-offs are equally real: - In case of illness or unexpected events, there is no backup. - There is no large organisation behind the report. - The name has no value to investors and partners. An independent review is a different product, not a discounted version of a full firm audit. It works best when the scope is clear, the researcher's expertise closely matches the code and the buyer cares more about direct expert involvement than branding. # Audit the Auditors Regardless of the size of your security partner, it is imperative you meticulously verify the people who will perform the work. Do not rely on reputation nor on the promises of sales.Before signing, ask: 1. Who exactly will review the code, and can we speak with them before committing? 2. Have those researchers personally reviewed this language, chain and protocol category? 3. Do they have public reports that they themselves produced? 4. Will this be 2 senior researchers or a junior/senior combination? 5. Who owns the architecture and threat-model discussion? 6. What happens if an assigned researcher becomes unavailable? These questions are not hostile. A serious provider should welcome them. # Match the Purchase to the Risk A large firm engagement makes sense when: - You have a serious post-deployment budget (>100k) - The codebase is very large (5k+ solidity, 10k+ rust) - Several areas of specialist expertise are required. - Investors or partners require a recognized audit brand. - The project needs organizational redundancy and capacity. A focused independent review makes more sense when: - The scope is limited. - The researcher is a well-known expert for this specific type of protocol. - There is no commercial or VC requirement for a famous logo. - The budget would otherwise force the team to choose between an inadequate engagement or no external review at all. Boutique firms sit between these two options. They are a very strong choice when deep expertise in a particular protocol category is the primary requirement.Sometimes the right answer is a combination. An independent review paired with a boutique review, for example, can deliver very high coverage without the cost and overhead of a full large-firm engagement. # Brand Is Valuable. So Is Knowing When You Do Not Need It A respected audit brand reduces uncertainty. If you have no reliable way to evaluate security researchers, reputation is a rational shortcut. It tells you that the company has survived previous engagements, built processes and earned trust from other teams.But a shortcut is not the same as certainty.If you can evaluate the people, verify their history and match their expertise to your system, you may be able to engage an excellent senior auditor without having to pay for the brand.The mistake is not choosing a large firm or choosing an independent researcher. The mistake is paying for one thing while assuming you received another. # A Direct Option I am a senior security researcher with four years in blockchain security, including time at Certora. I have led more than 40 audits and now conduct focused Solidity, Solana and Stellar reviews.If you believe I am a good fit, send me the repository and scope. I will tell you whether the code is ready and whether I am the right person for it. If someone else would be a better fit, I will gladly refer you to them.Security is expensive. Getting it wrong is considerably more expensive.
