The expertise you know us for, now always-on.

A one-off audit secures a moment. But you ship every day, and attackers don't wait for your next engagement. So we've made the review you already trust continuous and scalable: the same elite researchers, backed by AI-native analysis and a live bug bounty, watching your code long after launch, not just before it.

A point-in-time audit

  • Secures a single commit
  • One review, then a report
  • Coverage ends at launch
  • You triage findings alone

Cantina, always-on

  • Keeps watching as you ship
  • Elite researchers plus AI-native review, whenever you need them
  • A live bug bounty that never stops hunting
  • Expert triage, so you only see what's real
How it works

From first commit to always-on.

  1. 1

    Scope

    Tell us what you're shipping and when. Your code goes to the researchers who know your stack: DeFi, L1/L2, bridges, ZK, wallets, RWAs.

  2. 2

    Review

    Elite researchers and AI-native analysis go over your code together, giving you deep protocol reasoning and broad coverage in one engagement.

  3. 3

    Fix with confidence

    Every finding is validated for real impact and comes with the context your engineers need to fix it fast.

  4. 4

    Stay protected

    Launch a managed bug bounty and keep thousands of researchers testing your live code. We triage every submission, so you only see what matters.

Why teams building onchain choose Cantina.

The researchers everyone wants on their code

The same elite network, including Spearbit's top researchers, trusted for the highest-stakes reviews in crypto is reviewing yours.

Depth and coverage at once

Human experts reason about the economic and architectural attacks that break protocols, while AI-native review catches what a single reviewer would miss, so nothing falls through the gap.

You see signal, not noise

Every finding and every bounty report is triaged by people who write and break smart contracts for a living, so your engineers never waste time on spam or false positives.

Protection that doesn't end at launch

Your bug bounty keeps hunting long after the audit is done, so the code you ship stays covered as it changes.

What you can get.

Hybrid smart contract audits

The deepest possible look at your code: top independent researchers plus AI-native review in a single engagement. You get expert reasoning about trust boundaries, economic attacks, and protocol logic, with the coverage of automated analysis on top. It's where Spearbit's elite researchers do their work — the team behind the highest-stakes reviews in crypto.

Bug bounty

Keep thousands of independent researchers testing your live code, with expert triage so you never waste engineering time on low-quality reports. The safety net that catches what changes after your audit ships.

Growing beyond smart contracts?

As your protocol scales, so does everything around your code: cloud, infrastructure, internal systems, and the AI agents you're starting to ship. Attackers follow. When you're ready to secure more than the contract, the same researchers and AI-native approach extend across your whole surface.

Trusted by the best teams onchain.

  • Coinbase and Cantina have been strong partners for several years in the onchain security space. Cantina has found great researchers for flexible and timely audits. They have complemented our internal audits well.

    Anmol Malhotra

    Head of Product and Blockchain Security, Coinbase

  • Working with Cantina, especially in the lead up to v4 launch, has been invaluable. The team has been extremely responsive to all of our needs and their end to end approach to security has given us an increased sense of assurance: from the depth of the reviews to the bounty facilitation.

    Alice Henshaw

    Senior Protocol Engineer, Uniswap Labs

  • Moving our bug bounty to Cantina has been great. The triagers are deeply knowledgeable with smart contract development, so we don't have to waste engineering time responding to low quality submissions.
