    Happy to announce we’ll host the formal verification table in the Defence Summit next week. Alongside our partners @ethereumfndn @LidoFinance and @safe
    Safe.eth @safe
    🏏 Introducing the Ethereum Forward Defence Summit 📅 Nov 4, 2026 📍 MCA Club - Mumbai's iconic cricket club, five minutes from @EFDevcon venue. A private summit for the top order defending @ethereum and its protocols: Security researchers, protocol teams, wallet builders, critical infra leaders. The Agenda: Forward defence - Accelerating security of @ethereum and its protocols and apps, in the wake of relentless offensive AI. A day full of workshops, keynotes and hands-on building sessions. Hosted by @safe and @lidofinance. Supported by @ethereumfndn and its trillion dollar security (1TS) initiative. Seats are limited and strictly by approved application →

    RT @CoWSwap: The experts say that what we say is true. Limit prices hold, orders don’t overfill. Formally verified by @Veritylab.
    Verity @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.

    RT @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. 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.

    RT @Balancer: Balancer V3 has fifteen audit reports and they're the least interesting thing about how it's secured.

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