Research & Development
We turn recurring vulnerability patterns into public research and practical tooling.
Recurring bugs become public research and tools.
Investigating the failures that matter.
Smart contract & protocol security
Contract bugs, protocol assumptions, economic and access-control failures.
Exploit analysis
Rebuilding real incidents to see how weaknesses chained and why controls failed.
AI & emerging technologies
Risks in AI-assisted code, model integrations and autonomous agents.
Security tooling
Tools that help researchers find and validate vulnerability patterns faster.
From recurring bug to reusable defense.
What comes out of it.
Public & free
Security Research
Breakdowns of exploits, protocol weaknesses and new attack patterns.
AI security engine
Leon AI
AI-assisted analysis for smart contracts and other codebases, built to support researcher-led review.

Why clients trust us.
“Vaultline (formerly 0xTeam) provided us with a comprehensive audit that uncovered critical and hidden vulnerabilities. Their turnaround was fast, and communication was seamless. The team was highly professional and technically sound. We felt secure launching post-audit.”
Playarts Ai@playartsdotai“The audit experience with Vaultline (formerly 0xTeam) was exceptional. Their findings were detailed, accurate, and easy to follow. They identified logic bugs others missed. Our smart contracts are now more robust thanks to their efforts.”
DZap@dzap_io“Working with Vaultline (formerly 0xTeam) was smooth from start to finish. Their security insights helped us fix serious issues early. Their report was thorough, and the post-audit call added great clarity. Definitely our go-to team for future audits.”
Funtoken@funtoken_io“We needed a reliable audit before launch, and Vaultline (formerly 0xTeam) delivered. Their approach blended automation and manual review perfectly. The team was responsive, skilled, and security-focused. We gained major trust from users post-audit.”
AMGI Studios@amgistudios“We loved how hands-on Vaultline (formerly 0xTeam) was during our audit. They didn't just find issues, they educated us too. The report was actionable, clear, and helped our developers level up. Our product is now safer and play-ready.”
