EIP-7906 (Transaction Assertions via State Diff Opcode) was also considered for inclusion in Hegotá. It's live on our Hegotá testnet alongside frame transactions. If you haven't tried it yet, find out how here: faucet.hegota.ethrex.xyz/
EIP-8250 (Keyed Nonces) and EIP-8272 (Recent Roots) are now considered for inclusion in Hegotá. Both run alongside EIP-8141 (Frame Transactions) on our public privacy testnet, where you can already try them. We're excited to keep pushing privacy on Ethereum closer to users. If you haven't tried it yet, find out how here: faucet.privacy.ethrex.xyz/

We spent the last few days at the 29th Argentine Conference on Structural Engineering at the UNC Cultural Center. We presented our work on a structural engineering agent built on a verified solver, and introduced Stabileo (stabileo.com/es/) to universities across Argentina. Several researchers and academics showed interest in contributing to or using the project. AI is becoming a much more concrete topic in civil engineering.

Today we had the honor of attending the thesis defense of one of the students from our scholarship program at @Exactas_UBA. His thesis, “Preference Systems in LLMs: Effects of Textual Perturbations and Profile Elicitation on Consistency and Robustness in Decision-Making”. With LLMs becoming more capable and influential, research into how their preferences and values behave under different conditions is becoming increasingly important. Our program ran for a year and a half across three editions, supporting students in the final stages of their degrees and their research work. It was great to be there and see that journey come full circle. Congratulations, Augusto!

Ethereum’s privacy roadmap needs more than specs. It needs implementations that can be tested in the open. Proud to see @ethrex_client running a public testnet for these privacy-focused EIPs and opening it up for client teams to validate their implementations.
We are running a public testnet for the EIPs behind Ethereum's privacy roadmap, built on top of Glamsterdam. It runs EIP-8141 (Frame Transactions), EIP-8250 (Keyed Nonces), EIP-8272 (Recent Roots), EIP-7805 (FOCIL), and EIP-8369 (VOPS profiles), each implementation up to date with its spec. The frames implementation matches the latest execution spec tests release. Anyone can sync, peer, transact, and use the faucet to fund test accounts. The only permissioned part of the network is validator entry. If your client team is working on any of these EIPs and wants to validate, reach out to us, and we'll get you set up with deposit tokens.

Excited to see Propia out in the world. Built alongside @alignedlayer, Propia provides public infrastructure for verifying issuer authority, keys, and credential status, enabling verification without needing to call back to the issuer.
Verify a credential without calling the issuer. Propia is a public registry of issuer authority, keys and status. Any verifier can read it, and no personal data goes on it. Built with @class_lambda and @alignedlayer. propia.id/whitepaper

Proud to see a new digital identity wallet going live today in Bogotá, part of the infrastructure we've been building together with @alignedlayer for @sovraio and Propia. The wallet creates smart accounts with sponsored transactions on Sovra Chain, an Ethereum L2 running on @ethrex_client. It's especially nice to see this go live because it brings together a lot of the technology we've been working on for the last few years: from the execution client, to the rollup, to the wallet infrastructure. Having all those pieces working together also means we can keep almost the entire stack in house. This is the kind of real-world usage we build ethrex for. Not a testnet demo, but a live identity system handling real transactions for real citizens. Ethereum technology slowly becoming actual public infrastructure. Full whitepaper on the architecture here: propia.id/whitepaper/
Let’s make identity reusable across the city. Grateful to Bogotá for the trust. The SuperApp will give citizens verifiable credentials they control, not another silo. That stack is Propia + SovraWallet, built with @class_lambda and @alignedlayer. An open protocol, @ethereum secured, and a wallet that stays with the person. Thank you @Bogota @ConsejeriaTIC

Congrats to @WillyDuran65 on his new term as dean. Proud of the relationship we've built with the Faculty of Exact and Natural Sciences. Deep tech needs strong universities, and strong universities need companies that give back. Looking forward to what comes next.
I want to congratulate @WillyDuran65 on his new term as dean of the Faculty of Exact and Natural Sciences of the University of Buenos Aires. Willy thanked Francisco Strambini and me, and he also thanked @class_lambda for its contributions and its relationship with the university. I value that a lot. Most people on X have a somewhat wrong image of what Lambda is. Many believe we’re a devshop that works in crypto, when we have dozens of successful products in different industries and most of our core members are mathematicians, physicists, mechanical engineers, chemical engineers, civil engineers and industrial engineers and yes obviously computer scientists and computer engineers. Lambda is and has always been deep tech. If you want to build SaaS (something that we also do), you don’t need to understand what a Koopman operator is, finite element method or what Riemann zeta function is. But if you want to build companies at the frontier of science and engineering, you need people who understand things deeply and can work on hard problems. That’s why Lambda’s relationship with the University of Buenos Aires, with the Faculty of Engineering and particularly with the Faculty of Exact and Natural Sciences is so important and strategic. For me, the relationship with the university has always been strange and very personal. I’m a college dropout who, more than 15 years later, came back to reform the same degree program I had dropped out of. It’s a strange circle. I left the university without a degree, but part of the university is still shaping the way I think. I spent more than 20 years in the private sector learning how to build companies, products and technology. Now I’m using everything I learned to build a new degree program at the University of Buenos Aires. I want to create an elite of builders who want to innovate. Not an elite based on money, family or status. An elite based on knowledge, work and the ability to turn science and engineering into companies and good public policies. For me, this is not about proving that I never needed the university. It’s the opposite, it’s about giving back, closing a circle and helping create the education that I believe the next generation of builders needs. If we want to create a better world, we need to create companies that are at the frontier of science and engineering and that work with universities and the public sector. We also need to destroy this idea, that part of the left has, that companies go to public universities only to steal their knowledge or to destroy them. Real deep tech companies need strong universities. A deep-tech company has nothing to gain from a weak university. But this works both ways. Universities also need a big and capable private sector with the ability to innovate, turn knowledge into products and give back to the universities that made that innovation possible. Universities have the right environment to do research that is long term and doesn’t depend on the results of the next quarter. This is something that part of the right in Argentina doesn't understand. Companies need the public universtiy that is the one creating the most amount of professionals for our country and doing the best international research. The University needs money to be able to give freedom to researchers to work on difficult problems. Then companies have the ability to turn that research and knowledge into products, jobs and new industries. They have different roles, but they need each other. This shouldn't be an ideological debate but a practical one. Willy and I have our differences, as all good friend have, but we also have a very strong bond. We believe in science. We believe the state should invest in it. We believe this is better for the country, for universities and for companies. It’s a win-win. That’s why I value my relationship with Willy so highly. Even with our differences, we agree on what we want. Thanks Willy and I hope you keep doing an amazing job.
