Security infrastructure for agents

[SHEPHERD @Shepherd_HQ]

Smart contracts fail the same way systems do — not in isolation, but in interaction.

The code doesn’t break. The behavior in context does.
We don’t just scan for vulnerabilities. Our agents simulate the breach.

Introducing Shepherd: the autonomous operating system for smart contract security, built to test reality.

[SHEPHERD @Shepherd_HQ]

A lot has shifted in security over the past year. AI has made finding vulnerabilities significantly easier but it's also made the results harder to trust.

The volume of findings has gone way up while the confidence in any individual finding has gone way down.

The time between finding something and knowing whether it's real and worth acting on keeps growing.

We built Touchstone to compress that time. Give it a finding, get back a verdict backed by evidence.

Free to use, live today.

What you get back is a structured verdict. The reasoning, the evidence, and everything you need to act on it.

Get the full picture, make the call in minutes.

[SHEPHERD @Shepherd_HQ]

In an AI-first world, the hardest question in smart contract security isn't finding vulnerabilities anymore. 

It's knowing which ones are real.

Signal over noise.

█████ coming soon.

[SHEPHERD @Shepherd_HQ]

DeFi is moving at an incredible pace. Security can't afford to lag behind. As attackers increasingly move faster with more advanced tools, defenders need to do the same.

Our mission at Shepherd is to level to playing field. Teams should have access to the same caliber of tools attackers do.

We want to see this number go to zero.

Total exploited since Jan 2026: ~$137M+

It's only March.

Over the next year, smart contracts will be the software impacted by AI in the most unique ways.

Right now, we are in a weird middle ground. Proving agents assertions with verifiable, live EVM state needs to become standardized across the industry dev->audit->bug bounty->triage pipeline fast; or we risk choking the system with noise.

- AI is non deterministic technology
- Smart Contracts are deterministic technology

A match made in heaven when used correctly, a nightmare when combined blindly.

@Luffy_Bing Agreed 🫡 need to be more adversarial than the adversaries.

A closer look at how our AI simulations work.

More details in the case study.

[SHEPHERD @Shepherd_HQ]

@ebisu_finance is a CDP stablecoin credit market built on Liquity V2. They recently shipped leveraged vaults that handle looping complexity on behalf of users.

Ahead of launch, Ebisu brought in Shepherd to verify that every critical user flow behaves as designed under real conditions.

Check out the full case study below.
