Ethereum Researchers Propose Privacy Pool Gas Payment System for 2027 Upgrade

Ethereum researchers are pitching a package of transaction changes aimed at letting privacy pools pay their own gas and resist exclusion — without relying on third‑party relayers. The Protocol Architecture team, as highlighted by Ethereum Foundation researcher Toni Wahrstätter in an Aug. 17 X post, wants two features to take priority for the 2027 “Hegotá” upgrade: Frame Transactions (EIP‑8141) and Fork‑Choice Enforced Inclusion Lists, or FOCIL (EIP‑7805). What’s being proposed—and why it matters - Frame Transactions would introduce a programmable transaction format that gives wallets far more control over validation, execution and gas payments than the current fixed transaction model. Frames split transaction logic into programmable “frames,” enabling use cases such as gas sponsorship, alternative signature schemes, key rotation, and other flavors of account abstraction. - FOCIL would let a committee of validators publish inclusion lists that block builders are expected to honor. If a builder omits eligible transactions from an inclusion list, attesters could reject that block. FOCIL is already the only EIP currently scheduled for Hegotá. Combined, the two could change how private transaction pools operate. Currently, many privacy pools rely on relayers — services that submit transactions and pay gas on behalf of users. Relayers create an additional visibility point that can reveal transaction details, wallet behavior or other metadata. Wahrstätter argues that Frames would allow a pool itself to pay fees directly, removing the need for intermediaries, and that adding FOCIL would give those privacy transactions protocol‑level guarantees that they get included in blocks. Ancillary pieces and safety guards Wahrstätter’s preferred package also includes: - Keyed Nonces and Recent Roots (EIP‑8272): Keyed Nonces let an account maintain distinct transaction sequences; Recent Roots allow transactions to reference a recent Ethereum state without a single fixed block reference. - Transaction Assertions (EIP‑7906): Assertions let wallets declare conditions that must remain true during transaction processing, giving users a way to limit what can happen after they sign and submit. Those pieces are intended to work together: Frames for flexibility and fee payment, Keyed Nonces/Recent Roots for safer sequencing and state references, and Assertions for post‑signing constraints. Where the proposals stand EIP‑7805 (FOCIL) is slated for Hegotá today; EIP‑8141 (Frames) is still under consideration rather than formally scheduled. Client teams are comparing EIP‑8141 with a competing account‑abstraction design, EIP‑8130, before deciding which approach to move into implementation and testing. Wahrstätter framed his write‑up as the Protocol Architecture team’s view and a preferred package, not a final decision by Ethereum’s core developers. Hegotá’s place in Ethereum’s roadmap Hegotá is planned as the follow‑up to Glamsterdam, the upgrade aimed for delivery before the end of 2026. Glamsterdam centers on enshrined Proposer‑Builder Separation, Block‑Level Access Lists and changes to how network resources are priced. Hegotá candidates extend that work into privacy, censorship resistance, account abstraction, and state management. At the moment, 66 proposals are under discussion for Hegotá — a long list that does not mean all features will ship. Every EIP must compete for engineering resources, client support, testing time and space in the 2027 release schedule. Execution client teams must submit their Hegotá preference lists by Sept. 10; developers plan to compare EIP‑8141 and EIP‑8130 during an Aug. 25 breakout meeting, with a decision targeted for the Aug. 27 All Core Developers Execution call. Legal context in the U.S. While these technical changes concern how Ethereum processes private transactions, they do not alter laws governing money transmission, sanctions or illicit finance. The U.S. approach to crypto privacy tools has been contested: the Treasury lifted economic sanctions against Tornado Cash in March 2025 after reviewing legal and policy questions, but it has continued to warn about misuse by state‑linked hacking groups. In a separate criminal case, a Manhattan jury convicted Tornado Cash co‑founder Roman Storm in August 2025 of conspiring to operate an unlicensed money‑transmitting business, with prosecutors alleging the protocol moved more than $1 billion tied to criminal activity. Those legal developments underscore that privacy‑focused protocol changes do not replace compliance obligations for individual applications. Bottom line Wahrstätter’s proposal packages Frame Transactions, FOCIL, Keyed Nonces, Recent Roots and Transaction Assertions as a coherent path to self‑funded privacy pools with better inclusion protections. That view now needs client buy‑in, implementation work and testing — and it must compete with other priorities in a crowded Hegotá roadmap. Developers will be deciding which account‑abstraction design to endorse in late August, with formal preference lists due in September, setting the next chapter for Ethereum’s transaction model and privacy tooling.
