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.

so far in the last month: - tge of @alignedlayer - we are live with real users for our wallet as a service with @sovraio - we are helping propamms flourish on @ethereum with @class_lambda and @titanbuilderxyz - we launch a new product that is in stealth mode with @polfinance_

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!

Bread is here. This is a major milestone for @0xMiden and for making privacy practical and accessible. Proud that our team contributed to the technology behind it and helped bring this vision closer to users.

ethrex v27.0.0 adds state and block overrides to the RPC simulation methods. It also ships the Ethereum Foundation's new bootnode fleet for mainnet, Sepolia, and Hoodi, and stops transaction-admission rules from rejecting simulated calls. The override sets are the headline. eth_call, eth_estimateGas, eth_createAccessList, and debug_traceCall now accept the State Override Set and Block Override Set that geth defines, on both L1 and L2: per-address balance, nonce, code, state, and stateDiff, plus movePrecompileToAddress. Tooling that assumes those parameters exist, from forge script to Tenderly-style and MEV simulators to wallet balance previews and Multicall3 aggregators, now works against an ethrex RPC. Also in v27.0.0: - Bootnodes: the Ethereum Foundation's Node Infrastructure team is replacing the fleet that ships as the EF entries, and the new records are here. Five nodes per network, each serving mainnet, Sepolia, and Hoodi, geographically distributed, multi-cloud, dual stack, and spread across several discovery implementations, so one implementation bug cannot take the whole set down. It is a replacement rather than an addition, and third-party bootnodes and DNS discovery roots are untouched. Nodes pick the records up on upgrade, with no configuration change. - Simulated calls are no longer refused by transaction-admission rules. A call object carries no signature, so EIP-3607's contract-sender rule has nothing to protect: a smart contract wallet previewing its own transaction now gets a result instead of an error saying the sender should not be a contract. Transaction admission and block execution are unchanged. - A method in a namespace that is not enabled now says so, instead of reporting itself as not implemented. --http.api defaults to eth,net,web3, so debug_* probes against a stock node were reading as missing functionality when the handler was simply never reached. - Stateless-validator guests are on ERE v0.17.0, with the ERE version pinned by tag across the guest manifests and the release workflow. If you run ethrex, upgrade. No resync is needed.

EIP-8141 (Frame Transactions) is now a Hegotá headliner! We backed frames from the moment they were first proposed as one, and we've been building an implementation in ethrex ever since. That implementation now runs two public testnets: one dedicated to frame transactions, and one dedicated to privacy, which adds the companion EIPs also up for Hegotá: EIP-8250 (Keyed Nonces), EIP-8272 (Recent Roots), and EIP-7805 (FOCIL). The future of Ethereum is looking good, and you can already get a taste of it: faucet.privacy.ethrex.xyz faucet.frames.ethrex.xyz
⚡ ACDE #245 - ultra tl;dr: → 8141 (frame tx) confirmed as a Hegota headliner, alongside 7805 (FOCIL) 🏆 → first 14 DFI decisions made: 7819, 7851, 2488, 8219, 8182, 7645, 7923, 8200, 8188, 8358, 8115, 7862, 7807, 8094 🪓 video and summary: forkcast.org/calls/acde/245/

Great work @class_lambda and @ethrex_client. I’m proud of the team we have built.
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.

Thanks @VitalikButerin for sharing the work we are doing with @ethrex_client at @class_lambda. We’re very proud of what we built and I’m confident we will keep pushing the boundaries of what Ethereum can do. Right now I’m making sure we keep working on different important areas of Ethereum. Hopefully in the months to come we will have even better news. This is a two weeks old pic that I forgot to post with the team at the office and remote engineers connected via google meet. I didn’t drink my coffee yet as you can tell 😂.
Replying to @VitalikButerin
Also, @ethrex_client has a testnet for Frames, FOCIL plus companion EIPs that together allow privacy protocols on top of Ethereum to behave as full first-class citizens:
