It's a wrap on Berlin Blockchain Week! From Solidity developments to privacy, source code verification, and clear signing, the Argot Collective covered a lot of ground. ↓

We teamed up with Walnut to implement the ethdebug standard inside the Solidity compiler. The 2025 Solidity Developer Survey shows the demand clearly. This year we're tackling long-standing issues head on: alongside stack-too-deep, we're now taking on better debugging infrastructure.

Find us today at our booth at dappcon! x.com/dappcon/sta...

See you at Berlin Ethereum Day tomorrow! Start your day by learning what's coming up for Solidity, including a deep dive into how the team solves stack-too-deep, and say goodbye to YOLO-signing by lunch!

"Just formally verify everything!" Easier said than done. Zoe from the act team explains what's been holding back broader FV adoption and how she sees this changing with AI. Full conversation in the link below

Most people know Sourcify for source code verification. But the team has been an open source steward well beyond that. As part of the Clear Signing working group, they are going after blind signing, one of crypto's longest-standing UX failures. Check out what this means for the space 👇

Louder for everyone in the back: if your chain's data lives on a single database, its history can vanish! At EthPrague earlier this month Manuel from Sourcify showed how to prevent exactly that. Go watch the talk 👇

You still don't know what formal verification is and at this point you're too afraid to ask? Anja has got you covered. At EthPrague she gave a workshop explaining what FV is and how she and the rest of the act team approach it. Full talk in the link below 👇

The Solidity team is listening. At EthPrague, Jakob shared how developer survey feedback is driving what's next: fixing the biggest pain points and shaping the Core Solidity roadmap. Find the full talk in the link below 👇

2 hours left!

Prague, we're coming 🇨🇿 Argot will be at ETHPrague and we have a stacked weekend ahead: talks, a deep dive workshop, and hackathon bounties. Plenty of time to hang, hack, and build together. Find all the details below 👇

3 Argot projects are in the DAO Ethereum Security QF Round on Giveth : • Sourcify: the open source verification layer for Ethereum smart contracts • 𝗵𝗲𝘃𝗺: symbolic execution and equivalence checking for EVM bytecode • 𝗮𝗰𝘁: formal specification language & verification framework

What if a smart contract verification service just...disappears? Sourcify is built so that doesn't matter: open-source, public-good verification where anyone can self-host, the full dataset is published regularly, & is shared w/ the Verifier Alliance. 👇The TL;DR on what they do & why it matters.

Curious to hear what Sourcify has been up to? Tune in today 👇 x.com/ECHInstitut...

'Blind Signing' is Ethereum's biggest UX-security failure ✍️ Next week in Cannes, @kaanuzdogan.bsky.social will be joining the conversation on what it takes to finally move beyond. Catch him at WalletCon! Sign-up link below 👇 x.com/WalletConnec...

Have you ever stopped to think about who owns and controls Ethereum's source code verification data? Sourcify has thought about it - a lot. Manuel is bringing that conversation to EthPrague: the current state, what needs to change, and why it concerns all of us. → x.com/EthPrague/s...

We want to hear from you! Take 5 minutes to fill out Solidity's annual Developer Survey and help us shape its future! You might win a Devcon ticket ✨ ↓ x.com/solidity_la...

We're excited to announce the first official release of act (v0.2.0): a formal specification language and verification framework for Ethereum smart contracts, built within the Argot Collective. This is a major step in our research toward safer on-chain systems. ↓✨

Today, we are publishing our first Transparency Report. Financial and organizational transparency is a core value for us: public-goods stewardship must be grounded in openness, traceability, and clear responsibility.

Our bi-annual roadmap update is live: a recap of what Argot delivered across the collective in the second half of 2025, and a forward-looking outlook into the first half of 2026. ✨ Find the link below ↓

hevm is starting the year strong: v0.57.0 just landed 🚀 The release delivers meaningful improvements to the performance and reliability of symbolic exploration, with a clear impact on real-world contract analysis.↓

Time for a 2025 update on Fe! ⚡️ We believe language diversity & language research are essential to building safer systems. Fe is our exploration of that belief: a language that makes every side effect visible, prevents bugs before they happen, & pairs a modern DevX with a strict safety system.

What a year it’s been for @solidity_lang: a 10-year anniversary, the largest EF spin-off to date, a newly incorporated entity, and a roadmap that sets direction for the next decade. 🤩 Take a look at the most recent highlights with us ↓

There has been plenty of work coming out of the Argot Collective via hevm! This year, the focus was on shipping and hardening the tool, with two major releases landing over the past months 💫 Let's dive in ↓

2025 was a huge year for Sourcify! They shipped more than ever and laid down a rock solid foundation. Now it is time to look back 👇

As the year wraps up, we’re taking a moment to look back and highlight some of the work coming out of the Argot Collective - starting with Act ✨↓

With Argot's incorporation complete and all projects consolidated under one umbrella, we turn our full focus back to what we do best: building infrastructure for Ethereum applications. Today we're sharing a 2025 roadmap update detailing what each team is working on until the end of the year.

This week, all eyes on Solidity! The project recently celebrated its 10 year anniversary and shared its development journey over the past decade. What started with a few lines of code is today’s backbone of smart contract development.

.@solidity_lang, @SourcifyEth, @official_fe, @ethdebug, Act and hevm will now be maintained under the Argot Collective umbrella. As part of this change, corresponding Github repositories will be migrated to github.com/argotorg on Wednesday, August 27th at 9AM CEST.

Argot just got a new logo and website ✨ While our website got a new look, we continue what we have been doing best: Building the critical infrastructure for Ethereum applications.

Excited to share that hevm is powering the new Echidna's symbolic execution capabilities! Echidna, a Haskell program designed for fuzzing/property-based testing of Ethereum smart contracts, is entering a new era of symbolic execution with the support of hevm. All details and link below 👇

Our weekly spotlight rolls on! Today we’re zooming in on sourcify.dev 🧿 They're on a mission to fix smart contract verification to uphold Ethereum's open-source core values, increase resilience and lay the groundworks for innovation. Here is why this is so important 👇

Today's spotlight is on Ethdebug 🪲 @ethdebug is an emerging standard debug‑info format for smart contracts. It lets compilers emit rich, language‑aware data so debuggers and explorers can map bytecode back to source with precision.

We’re thrilled to share a major milestone: Argot has secured foundational funding from the @ethereum.foundation! This significant support ensures we can sustain and advance critical open-source infrastructure for @ethereum.bsky.social. Find all details on our blog or follow the tl;dr here👇

In a new explainer post, Solidity shares its perspective on EOF and how it will benefit compilers, L2s, applications, and tooling. You can read the full post on the blog: soliditylang.org/blog/2025/03...
