Ethereum Foundation Locks Two Must-Ship EIPs Into Ethereum (ETH) Hegotá

Ethereum Foundation Names Two Must-Ship EIPs

The Ethereum Foundation's protocol team on September 7 drew a hard line around what the next hard fork must contain, designating two Ethereum improvement proposals for the Hegotá upgrade that carry a must-ship designation for client teams and the validator set alike. The department assessed 62 candidate EIPs and, for the first time, issued a single department-level verdict rather than splitting positions across individual working groups. The two proposals that earned mandatory status are EIP-7805, known as FOCIL, and EIP-8141, which introduces frame transactions. FOCIL sits on the consensus layer and forces committees of validators to push inclusion-list transactions into blocks, preserving a route for any transaction to clear without depending on a single block builder — the censorship-resistance backbone of the fork. EIP-8141, an execution-layer change, is examined below. In the official Hegotá EIP rundown, the team positions Hegotá not as the quantum-resistance switch itself but as the fork that decides whether a later post-quantum fork lands on schedule, under a target of a quantum-resistant layer 1 by December 2029. Fifteen further EIPs are likely to ship and 28 were rejected, with implementation work starting in the October-December 2026 window. For readers new to how such forks reshape the chain, our Ethereum 2.0 upgrade guide walks through the history.

190,628 Gas vs a 100,000 Cap

EIP-8141's privacy ambitions have hit a hard numeric wall. A benchmark published on September 2 measured the cost of verifying a Groth16 zero-knowledge proof — the cryptographic receipt attached to a private transaction — at roughly 190,628 gas, nearly double the 100,000-gas verification cap set in the proposal's current draft. Pairing checks alone consume about 181,000 gas, so the cap is breached before any execution even begins. The research model behind the benchmark put a one-note private transaction at a minimum of 211,828 gas and an eight-note transaction at 351,828, though these are modeled estimates, not confirmed mainnet costs. A September 5 revision to the EIP offers a compromise: keep the 100,000-gas cap as the common standard every node must honor, while letting individually high-performance nodes accept transactions above it. That only partially resolves the problem, because a transaction accepted by one node still has to propagate — privacy protocols such as Tornado Cash and RAILGUN need every relaying node to verify the proof, not just the fastest ones. The benchmark's author argues that ordinary optimized transactions require a cap of at least 250,000 gas, a change not yet reflected in the proposal. A separate draft, EIP-8250, would cap pending frame transactions per sender in the public mempool at one, another constraint for privacy services that reuse a single address across payments.

Buterin Confirms Fee Abstraction Progress

Vitalik Buterin said on September 6 that work on EIP-8141 had advanced quietly over recent months, describing on X a design that would let users settle transaction fees in tokens other than ETH — or hand the bill to a third party. The mechanism restructures a transaction into a chain of up to 64 frames, each behaving like a call into smart contracts: one frame verifies the transaction's validity, one authorizes the fee payer, and the remaining frames execute the user's intent. Because fee approval is isolated in its own frame, the account signing a transaction and the account paying for it are decoupled, so a wallet holding only a stablecoin can pay fees in an ERC-20 token. Account abstraction under ERC-4337, live since 2023, already enabled this, but through a separate mempool and third-party bundlers; frame transactions move the capability into the base protocol, and a default-code feature extends it to ordinary externally owned accounts without migrating to smart accounts. At the August 27 core developer call that locked EIP-8141 frame transactions into the 2027 Hegotá upgrade, the proposal was promoted to adopted-for-inclusion status, with FOCIL expected to ship alongside. It remains a draft: it still faces client integration, testnet validation, wallet support and security audits, while developers weigh a comparable proposal, EIP-8130.

The Gas Cap Sets the Privacy Ceiling

Further detail from the Ethereum Foundation's announcement clarifies Hegotá's place in the roadmap: the upgrade follows Glamsterdam, which the foundation expects to execute in December 2026, with client teams able to begin Hegotá implementation in the second half of Q4 2026. Roughly 60 researchers and engineers assessed the 62 proposals, and the foundation stated that if an S-tier proposal runs into trouble, it will adjust the upgrade schedule before removing it from scope. FOCIL is to ship together with EIP-8369, which defines eligible transactions, while EIP-8141 pairs with privacy proposals EIP-8250 and EIP-8272. Both proposals carry a Scheduled for Inclusion designation even though their specification documents remain in Draft status. Frame transactions also support key rotation, batched operations and introducing new signature schemes without a hard fork — a capability the foundation says underpins the move to quantum-resistant signatures.

Additional details from the foundation's September 8 disclosure flesh out how the Hegotá tier list was built. The 62 proposals drew 397 individual grades — an average of 6.4 per EIP, with the most-reviewed proposal receiving nine — before contested candidates were debated in roughly 90-minute working sessions; team-level scores stay private, and the department applied a steelman reading to each proposal. FOCIL earned its S-tier slot unanimously, with all seven reviewers giving it the top grade, while EIP-8141 averaged 3.89 points across nine reviews. Beyond the 15 likely and 28 rejected proposals already known, eight EIPs sit at B-tier, seven at C-tier, and EIP-8368 and EIP-8372 are deliberately unrated pending mainnet data from Glamsterdam. The December 2029 quantum-resistance deadline is described as non-negotiable until at least January 2027, when it will be reassessed with outside experts, and the department will host a public Reddit AMA on the rankings on September 16.

(as of 05:15 UTC) The thread running through all three developments is that Ethereum's governance runs on rough consensus rather than token-weighted ballots — there is no on-chain vote, so the outcomes that matter are recorded in the process itself: the drafted EIP-8141 text with its 100,000-gas verification cap and 64-frame structure, the August 27 adopted-for-inclusion decision, and the September 7 must-ship ruling on EIP-7805 and EIP-8141. Our read: the protocol team has fixed the fork's floor, and the gas-limit debate now decides its privacy ceiling. If proof verification cannot be cut below the cap, frame transactions may reach Hegotá with weaker privacy than Buterin's framing suggested. We track the fork's next steps in our Ethereum network coverage.
