What the official materials say
1) Spearbit homepage / redirect
- URL: https://spearbit.com/
- Key takeaways:
- The live Spearbit homepage no longer behaves like a standalone operating site; it redirects with the message that Spearbit now lives on Cantina
- This is the clearest current evidence that the old Spearbit commercial surface has been folded into Cantina rather than remaining fully separate
- That matters for classification: Spearbit is still worth cataloging, but as a security network / report corpus whose live sales surface now sits inside a broader platform
2) Cantina homepage
- URL: https://cantina.xyz/welcome
- Key takeaways:
- Cantina now describes itself as an AI-native security platform combining advanced AI with domain experts across development and production security
- The page still distinguishes between “Cantina reports” and “Spearbit reports,” which suggests the Spearbit label continues to denote a recognizable review lineage or report class inside the merged platform
- This is useful context because it shows Spearbit did not simply disappear; it was absorbed into a wider security platform while preserving some brand continuity
3) Spearbit portfolio repository
- URLs:
- Key takeaways:
- The README says Spearbit is a network of expert security engineers offering reviews and other security-related services to web3 projects
- It explicitly describes enabling expert freelance auditors to work together on interesting projects, which is a strong clue about Spearbit’s operating model as a curated network rather than a simple fixed-staff consultancy
- The repository hosts a large public corpus of reports across DeFi, infrastructure, staking, bridges, governance, wallets, ZK systems, and related categories
- The report table remains current deep into 2025, which indicates that the public audit corpus is still an important first-party source of truth even after the Cantina shift
4) Spearbit Armory repository
- URL: https://github.com/spearbit/armory
- Key takeaways:
- The repository describes itself as a one-stop shop for blockchain security researchers looking for educational material and alpha to level up
- Public materials include ZKP education, report and findings breakdowns, security tips, researcher spotlights, seminars, and protocol diagrams
- This makes Spearbit useful to catalog not only as an audit network but also as a public security-education and researcher-enablement corpus
5) Spearbit GitHub organization
- URL: https://github.com/spearbit
- Key takeaways:
- The org includes the public portfolio and armory repositories plus other odds-and-ends, making GitHub one of the clearest surviving first-party surfaces for understanding the brand
- Even if the commercial website has moved, the GitHub footprint preserves a substantial public record of how Spearbit operated and what kinds of materials it published
Whitepaper / technical-doc status
- No canonical Spearbit whitepaper or litepaper surfaced in this pass.
- The best current primary-source set is the redirecting homepage, Cantina’s platform page, the public audit portfolio, and the public education repository.
- The practical source of truth is therefore a mix of current platform branding and legacy-but-still-live GitHub repositories.
Research notes
- Best current category for the library: blockchain security research network / audit-report infrastructure / security education corpus.
- Spearbit is notable because it shows a transition path from elite audit network to sub-brand or report lineage within a broader security platform.
- The public portfolio and armory repos are unusually valuable because they preserve both client-facing audit history and researcher-facing educational content.
