We secure critical software with formal verification

[Ethereum Foundation @ethereumfndn]

We've come a long way in a short time for formal verification—one of our strongest tools for putting the S in CROPS—to become a new normal. Here, verity formally verified EIP-8282 and in doing so found real discrepancies for researchers to address.

Thanks for the work @Veritylab

[Verity @Veritylab]

We formally verified EIP-8282 for the @ethereumfndn.

Proved directly on the bytecode, checked by Lean.

When I tweet, saying we're using a ton of inference this is for things like this.

@Veritylab re-audited every Cairo zero contract ever deployed to find 80 vulnerable ETH

If you are an L1/L2 right now, you should re-audit every contract yourself with a fleet of agents, giving them context on the different changes introduced over the years (we can help too).

[Verity @Veritylab]

@StarknetFndn Always a pleasure to help :)

[Verity @Veritylab]

We saved 82.81 ETH on Starknet last week using a fleet of obliterated agents.

This isn't an isolated case; we believe far more funds sit in legacy protocols, and agents make stealing them cheaper every month.

@ethereumfndn Bring your agents, make the EVM faster with FV :)

[Verity @Veritylab]

@yukonresearch @zksecurityXYZ @ethereumfndn Bring your agents, make the EVM faster with FV :)

[Yukon @yukonresearch]

New challenge on Yukon: https://t.co/scvn1oBh8k, with @zksecurityXYZ, @ethereumfndn and @Veritylab

Ethereum is moving toward proving every block in real time, and nobody has a proven bound on what it costs to validate one inside a zkVM.

The record right now is infinity, so bring your agents.

[Verity @Veritylab]

We're happy to partner with the @ethereumfndn, @yukonresearch, and @zksecurityXYZ to make the EVM faster using formal verification with https://t.co/eUpvDVGAyP

[Ethereum Foundation @ethereumfndn]

What's the most work that could possibly be required to verify an Ethereum block?

Today, we can't prove an answer. All we know is the validator always finishes. https://t.co/Y5w3tlKLCC is an open challenge to change that: contributors compete on a leaderboard to find mathematically guaranteed bounds for verifying Ethereum, no matter what's in a block.

Built on Yukon in collaboration with @zksecurityXYZ, @Veritylab, and @yukonresearch, https://t.co/Y5w3tlKLCC seeks provable limits that keep verification cheap, predictable, and possible on modest hardware.

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 → https://t.co/KCbteRvUDH

[CoW Swap @CoWSwap]

The experts say that what we say is true. Limit prices hold, orders don’t overfill.

Formally verified by @Veritylab.

[Verity @Veritylab]

@CoWSwap Great working together on this!

[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.

[Verity @Veritylab]

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

https://t.co/YSsClSILY0

[Verity @Veritylab]

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

@eniwhere_ Fable pricing makes it less interesting for long-horizon Ethereum proving work.

That being said, we would still love to benchmark it in the future.

We're on the @AnthropicAI waitlist to get research API credits

[Verity @Veritylab]

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

[Verity @Veritylab]

@Fricoben 🫡

[Verity @Veritylab]

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

[Verity @Veritylab]

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.
