On-chain AI systems

Why Vaultline
Why Work With Vaultline
01. We published the risks before the market priced them.
Our research on autonomous on-chain agents, AI-agent trust chains, and AI agent audits is public. Read our thinking before you engage it.
02. We secure the money side.
Most AI security firms have never traced a fund flow. We audit systems where a model's mistake is a drained wallet. Those are the stakes we've worked at since day one.
03. We build with AI, so we know where it breaks.
Leon AI, our vulnerability-detection engine, is built in-house. We know model failure modes from the builder's side, not just the auditor's.
