Verity

We secure critical software with formal verification

[Royco @roycoprotocol]

@Veritylab completed an unbounded formal verification of Royco Day's accounting.

Junior absorbs losses first, and Verity checked every possible case to confirm it.

In our formal audits, we start by mapping the full system dependencies to then formally verify their smart contract.

For @unlink_xyz, this gave strong confidence in their contract plus a clear view of what their system depends on and needs monitoring going forward.

We've been banned by @OpenAI three times to benchmark GPT 5.6 Sol against the most popular Solidity Audit Skills

1. GPT + @cyfrin Skills - 16/35 -vulnerabilities found
2. Raw GPT 5.6 Sol - 12/35 vulnerabilities found
3. GPT + @pashov Skills - 12/35 vulnerabilities found
4. GPT + @QuillAudits_AI Skills - 11.3/35 vulnerabilities found

Our Conclusions

1. Models alone are good enough for general vulnerability detection. A generic audit skill didn't help (exception for @cyfrin). We feel skills work best when encoding your own context (architecture, invariants, threat model)

2. Permissionless security work is getting harder. We got banned three times before being verified for OpenAI Cyber Preview access.

3. Do we actually still need auditors? Cyber is a market: attacks improve, defense adapts, and vice versa. AI may not do an auditor's job well yet, but eventually it will (even for formal verification).

The question is: how confident are you that it's good enough, and how well do you understand it?

Given blockchain's security stakes, we believe that's worth the time and effort to verify.

@Balancer Happy to work with you guys on the comeback 🫡

[Balancer @Balancer]

Balancer V3 has fifteen audit reports and they're the least interesting thing about how it's secured. https://t.co/sFXHX1eWNG

[Aragon.eth 🦅 @AragonProject]

Aragon OSx’s execute() authorization logic has been formally verified by @Veritylab, proving 16 properties with a transparent methodology and public proofs.

Review the findings. ↓

@AragonProject Happy to have worked with you guys on this spec!

@tek_kac Thanks for your work !

[fricoben @Fricoben]

Our formal audit of @unlink_xyz is out

Always a pleasure to collab with my friend @phklive and his cracked team

[tekkac @tek_kac]

Really enjoyed working together to find the right invariants and formalize them with explicit assumptions.

Excited to see where Verity takes this.

[Verity @Veritylab]

We've formally verified @unlink_xyz

This engagement uncovered 11 scored findings and 4 core guarantees verified.

This summer will be formal maxxing for @Veritylab

[Verity @Veritylab]

As part of our research with @Superfluid_HQ , we formally verified a core streaming rule of the protocol
