Cantina Competitions are crowdsourced security reviews powered by Cantina Code to be efficient, high-signal, and provide maximum code coverage for web3 protocols seeking mass-scale reviews from the best security researchers across the ecosystem, all competing and incentivized by a pot put forth by the protocol. With Cantina Competitions you will have hundreds of quality security researchers scouring your codebase.

Cantina Bounties enables protocols to tap into a rich network of the best security researchers Web3 has to offer in order to uncover and report bugs for your protocol. By pairing these security researchers with Cantina Code, you can streamline your communications and quality control submissions along with spam during the code review process.

Cantina Guilds offers a bespoke experience. Each guild, including Spearbit, has its own set of standards to ensure quality. Cantina Guilds enables clients to access niche security talent for OPSEC reviews, penetration testing, curated fuzzing, Cosmos and Solana expertise, and more. For services provided by a guild, the logo of that specific guild will appear on the report, lending their own reputation and credibility. Guilds also have the liberty to set their own pricing, which will vary from guild to guild.
