We secure critical software with formal verification

The experts say that what we say is true. Limit prices hold, orders don’t overfill.
Formally verified by @Veritylab.
We formally verified that @CoWSwap's settle() computes every successful trade at or above the user's signed limit price, without overfilling the order.

We formally verified that @GearboxProtocol's BytecodeRepository keeps its latest-version indexes exact
We're looking forward to collaborate more with one of the OG lending protocols of the space

We’ve formally verified @zodiaceco’s Roles v3 ABI decoder.
We're looking forward to continue to collaborate with Zodiac to secure one of the most critical component of Ethereum multi-sigs

Coding benchmarks did not match what we were seeing when using LLMs for formal verification.
So we built our own.
Today we’re releasing Ethereum Verification Benchmark V2
Along the way, we found something even more interesting.
With enough effort, smaller models replicated 96% of the tasks solved by frontier models.
The scaling-law sidecar remains a useful view of how inference effort changes proof solve rate.
This new version includes different types of protocols ranging from AMMs, bridges, token standards, account abstraction, streaming, vaults, auctions, liquid staking, governance, confidential tokens, and more.
Thanks to @1inch @Superfluid_HQ , @0xT3tris @yield @StarkWareLtd @roycoprotocol @AragonProject @paretocredit and many all others for their help

@Veritylab completed an unbounded formal verification of Royco Day's accounting.
Junior absorbs losses first, and Verity checked every possible case to confirm it.
Read the full verification below 👇

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.

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. ↓
Our formal audit of @unlink_xyz is out
Always a pleasure to collab with my friend @phklive and his cracked team

Really enjoyed working together to find the right invariants and formalize them with explicit assumptions.
Excited to see where Verity takes this.
