Pre-audit · Your first engagement with Zealynx

The Founder Security Sprint.

The way to start working with Zealynx. Three days of senior audit work on your highest-risk contracts, a written memo you can put in front of investors and partners, and the full $1,500 credited toward your full audit when you go ahead.

$1,500 one-time · Credited toward your full audit · 12 months of Zealynx Insiders included

Run by the firm behind 49 audits

Who this is for

Start with three days, not a five-figure commitment.

Choosing an auditor

See the work before you commit.

Picking an audit firm is a five-figure decision, usually made from a sales call and a PDF of past reports. Judge us on your own code instead. If you go ahead, the Sprint is already paid for.

Pre-raise

Building toward a raise.

Investors will ask what you have done about security. “Nothing yet” is a bad answer. A senior review with a written memo, and a firm already lined up for the full audit, is a good one.

Before the full audit

Get audit-ready while the code is young.

The expensive problems are decided early: trust assumptions, roles, how value moves. Catch them now, and the full audit goes deeper instead of rediscovering them.

Before you write the code

Still at the drawing board? That is the cheapest time to talk.

Most of what goes wrong in Web3 is decided before a line of code exists: who is trusted, what a role is allowed to do, what happens when a price goes stale, who can be griefed by whom. Once it is written, changing it costs a rewrite. At the design stage it costs a conversation.

So you do not need finished code to get value from this. Bring the architecture you are unsure about, the flows you cannot decide between, the assumption you quietly hope holds. We will tell you where it breaks while it is still cheap to move.

Your three days do not expire

The three days are yours for 12 months, not a date fixed at checkout. Redesign, delay, pivot, ship late: the senior time waits until your code has settled.

What starts the day you book is direct access to us, which is worth most while the decisions that determine your risk are still being made.

What you get

A real engagement, not a drive-by scan.

  1. Kickoff threat-model session.

    A 1:1 with Zealynx's founder. We walk your architecture together: where the money moves, what can go wrong, and what your riskiest assumption is. You leave with a one-page risk map most teams never had before their first audit.

  2. A three-day pre-audit on your core contracts.

    Three full days of senior time dedicated to your highest-risk surface. We run Zealynx's internal AI audit pipeline over your repo, the same tooling we use in full engagements, and a senior auditor personally verifies and triages every finding. No raw tool dumps. At our standard audit rate of $6k per week, this session alone is $3,600 of senior time, for $1,500. The days are yours for 12 months: spend them whenever your code has settled, not on a date fixed at checkout.

  3. Findings walkthrough plus a written review memo.

    A live call where we go through each issue and, more importantly, why it matters. You keep a written memo: findings, severity, and what to fix first. It is yours to share with investors, partners, and users as evidence that senior auditors have been through your code.

  4. One fix re-check round.

    You patch, we verify. The difference between a drive-by review and an engagement is that someone checks the fixes actually fix.

  5. Every dollar credited toward your full audit.

    When you are ready for the full engagement, the $1,500 comes off your Zealynx audit quote, as long as you book it within 12 months of your Sprint. Sprint clients get priority scheduling, and we start the audit already knowing your protocol, which makes it faster and better.

  6. Visibility for your protocol.

    A security-process interview on Zealynx's YouTube channel, shared across both our audiences: how you build, how you think about risk, what you have done to protect users. Security you cannot talk about is marketing you never used.

  7. Twelve months of Zealynx Insiders, included.

    So you are not on your own between the Sprint and the full audit: 1:1 advisory with working auditors, office hours, Krait runs on your contracts, and live audit workshops where your protocol can be the target. The full list lives on the membership page.

We schedule the three days together at kickoff, at the point in your build where a review does the most good.

Carlos Vendrell, founder of Zealynx
Carlos VendrellFounder · Zealynx

Choosing an audit firm is a five-figure decision, and most teams make it from a sales call and a PDF of past reports.

I would rather you judge us on your own code. Three days, our senior auditors, your highest-risk contracts. If the work is good, you continue with the full audit and the Sprint is already paid for. If not, you still leave with real findings.

The Sprint is how working with us starts.

FAQ

Questions.

No, and this is the most common mistake we see. The three-day pre-audit does not expire: it is yours to spend any time in the 12 months after you book, whenever your code has settled. What starts the day you book is the advisory access, and that is worth most while you are still choosing how the thing should work. Book now, bank the three days, and arrive at them with better architecture.

Yes, and we would rather. Bring the architecture, the trust assumptions, the roles, the flows you are unsure about, through the kickoff threat-model session and the 1:1 advisory and office hours included with your Sprint. Most of what goes wrong in Web3 is decided at the design stage, before a line of code exists; catching it there costs a conversation instead of a rewrite. This is advisory time rather than an open-ended architecture engagement, but for the questions that actually keep you up at night it is the highest-leverage hour you will spend.

Four steps: a 1:1 threat-model session on your architecture, a three-day pre-audit on your core contracts (our internal AI audit pipeline plus senior manual verification), a findings walkthrough call with a written memo, and one re-check round after you fix. We schedule it together at onboarding, at the point in your build where it does the most good, and it can wait as long as you need it to.

We pick a member protocol and put it in front of the room: Insiders auditors work through the codebase together in a live session, moderated by a Zealynx senior, hunting real bugs in real code. It works like an internal, trusted bug bounty: many qualified eyes, findings curated and handed to you, and no public disclosure. Your repo needs to be shareable with the room (open source, or you consent to sharing it with members). Founders get eyes they could never afford; auditors get real targets; everyone levels up.

Two channels. First, a security-process interview on Zealynx's YouTube channel: not a 'who are you' intro, but a walkthrough of how you approach risk and what you have done to protect users, the kind of content that builds trust with integrators and future users. We both share it. Second, the Insiders room itself: you can demo your protocol or run a workshop in front of a community of builders and auditors, the people most likely to integrate you, contribute, or refer you. For an early protocol with no VC network, this is distribution you cannot buy elsewhere.

Smart contracts in active development or deployed, on any chain we cover (EVM, Solana, and others). For larger codebases we scope the review to the highest-risk surface together during the kickoff session. The point is maximum risk reduction per hour, not exhaustive coverage.

The full $1,500 is deducted from your Zealynx audit quote when you book the audit within 12 months of your Sprint, and Sprint clients get priority scheduling. By then we already know your protocol, which makes the audit faster and better.

You can go straight to a full audit, and if your code is final and your launch is close, you should. The Sprint is for teams who want to see how we work before committing to a five-figure engagement, or whose code is not settled yet. It finds the expensive problems early, so the full audit goes deeper instead of rediscovering them, and the money carries over.

Our membership for builders and auditors: direct access to working auditors, office hours, Krait (our AI auditor) runs on your contracts, and live audit workshops. You get 12 months of it so you have someone to ask between the Sprint and the full audit. It is a bonus on top of the engagement, not the product. See the membership page for the full list.
