Ethrex Privacy Testnet, Hegotá Tier List, PQ Roadmap

Happy Monday, September 7, 2026.

Ethrex launches a public testnet with Privacy EIPs. Vitalik says Frames support long-term scaling. And the EF Protocol team releases its Hegotá EIP rankings alongside priorities for achieving post-quantum Ethereum.

Ethrex Launches Privacy Roadmap Testnet

Ethrex launched a public testnet running core EIPs from Ethereum's privacy roadmap on top of Glamsterdam. The testnet features support for EIP-8141 Frame Transactions alongside EIP-8250 Keyed Nonces, EIP-8272 Recent Roots, EIP-7805 FOCIL inclusion lists, and EIP-8369 VOPS validation profiles. Anyone can sync, peer, transact, and request funds from the testnet faucet.

The testnet showcases how private transactions can be sent through a privacy pool directly into the public mempool without relayers or trusted intermediaries. The upcoming combination of FOCIL for censorship-resistant inclusion, recent roots for stable proof generation, and keyed nonces for parallel transactions will enable native L1 privacy. The EIPs are proposed for inclusion in the Hegotá upgrade. Ethrex is a lightweight Ethereum execution client built in Rust.

Frames As Final Transaction Type

Geth core developer Lightclient published an architectural overview of EIP-8141 Frame Transactions, concluding that Frame Transactions should be the final transaction type Ethereum ever enshrines for accounts. Lightclient says frames provide the necessary primitives for validation abstraction without requiring custom protocol containers. By breaking transactions into general-purpose execution segments with defined modes, frames decouple basic protocol responsibilities from arbitrary validation logic.

The design provides extensibility while preserving static observability. Frames consist of canonical helper contracts and validation prefixes that will enable native expiring transactions and relayer-less privacy pool withdrawals using recent roots and keyed nonces. At the execution level, specialized frame modes and targeted opcodes support post-transaction assertions to support post-quantum signature aggregation schemes.

Vitalik Buterin highlighted that EIP-8141 extends beyond account abstraction into supporting long-term scaling by separating transaction dependencies from state-modifying actions. Transactions with statically provable dependencies, such as standard transfers, can be validated and batched with minimal overhead, while complex dynamic contract calls incur standard execution gas.

EIP-8141 Frame Transactions is scheduled for inclusion in the Hegotá upgrade, anticipated to go live sometime in 2027.

EF Protocol Hegotá EIP Rankings

The Ethereum Foundation's Protocol Cluster published its first unified priorities list of all 62 EIPs proposed for the upcoming Hegotá upgrade. The list aggregates 397 rankings from 60 researchers and engineers across nine teams. The cluster designated EIP-7805 (FOCIL) and EIP-8141 (Frame Transactions) as must-ship S-tier headliners that define the fork's scope.

The team's high-priority A-tier selections include EIP-8250 Keyed Nonces and EIP-8272 Recent Roots, EIP-7906 post-transaction state assertions, EIP-8025 zkEVM integration, EIP-8369 VOPS profiles for censorship resistance, and an initial set of post-quantum migration primitives. In total, 28 proposals were declined for inclusion, including contested staking and issuance changes such as EIP-8363 and EIP-8142 block-in-blobs. The Protocol Cluster will host a Reddit AMA on r/ethereum on September 16 at 2:00 PM UTC to discuss the tier rankings and upgrade roadmap. You can submit your questions now!

Post Quantum Ethereum By 2029

The EF Protocol Cluster also published its priorities for achieving post-quantum resistance across execution, consensus, and data layers on Ethereum L1 by December 2029. The post-quantum goal currently requires 5 hardforks after Glamsterdam to the L* hardfork, an average ship time of 7.2-months per fork. Alternatively, an intermediate Minimum Viable Post-Quantum (MV-PQ) fallback is listed in the J* hardfork on Ethereum's strawmap, achievable in a 1-year cadence.

The fallback specification outlines a post-quantum public-key registry in I*, followed by a consensus-layer heartbeat, leanDA sampling on the data layer, and leanSPHINCS transactions on execution in J*. All development operates across five multi-fork research arcs: fast finality, post-quantum, privacy, state, and zkEVM. A post-quantum Ethereum secures Ethereum accounts, signatures, and network state against future quantum computer attacks.
