Hegotá Moves Ethereum Gas Buying From Users to Apps

Ethereum core developers scheduled EIP-8141, Frame Transactions, for the 2027 Hegotá upgrade on August 27. A wallet that holds only stablecoins could send them without keeping ether for gas, if an app or another account fronts the fee. The network still charges that fee in ETH.

The Ethereum Foundation Protocol cluster graded that change S, the must-ship mark, because it lets accounts drop secp256k1 keys without a hard fork for each new scheme. Stablecoin gas is the part users will notice. The fork-defining job is a path off today’s signatures before the 2029 quantum target.

ETH Remains the Only Protocol Fee

The draft of EIP-8141, created on January 29, 2026, adds a new transaction type that splits validation, gas payment, and execution into ordered contract calls called frames. Fees in the payload are still the EIP-1559 pair, max fee per gas and max priority fee per gas, denominated in ether. Nothing in the envelope lets the protocol take USDC.

Ten authors are on the draft, including Vitalik Buterin, lightclient, Felix Lange, and Yoav Weiss. The type identifier is 0x06. Intrinsic cost is 12,000 gas, plus 475 gas per frame, with a cap of 64 frames. Each frame runs in one of three modes.

THE THREE FRAME MODES

A VERIFY frame that approves payment can point at a sponsor. That sponsor burns ETH to the network. The user’s frame can then send the sponsor USDC, or any other ERC-20, as a normal transfer. From the user’s screen it looks like a stablecoin fee. From the protocol’s screen it is still an ether bill.

That split is the whole trick. The account that authorizes a swap no longer has to be the account that holds the ETH.

An S Grade Built for Signature Schemes

On September 7, 2026, the Protocol cluster published its first unified Hegotá tier list, scoring 62 proposed EIPs. About 60 researchers and engineers took part. Twelve of 16 contribution templates carried grades, 397 in all, or 6.4 grades per EIP.

THE GRADING PASS

• S, must ship: Defines the fork; if an S item slips, the schedule moves before the scope does.
• Frame Transactions: S, average 3.89 from 9 grades, locked execution-layer headliner.
• FOCIL, EIP-7805: S, average 4 from 7 grades, unanimous, locked consensus-layer headliner.
• The cut: 2 must-ship items, 15 expected to ship, 28 declined with stated reasons.

The note beside EIP-8141 does not mention stablecoins. It names security.

Locked-in EL headliner. Native account abstraction on security grounds: a path to PQ signature schemes without a fork per scheme, aggregation so PQ verification can be priced, and a route to retiring k1 keys. Ships with EIP-8250 and EIP-8272.

Ethereum Foundation Protocol Cluster, Hegotá EIP Opinion Post, September 7, 2026

S scores 4 points, so 3.89 means almost every grader put Frames in the top bin. The companion priorities post is blunter still: Hegotá is not the post-quantum fork. It is the fork that decides whether the later quantum forks still hit December 2029.

How a Wallet With Only Stablecoins Sends a Swap

Take a wallet that holds USDC and no ETH. Today that wallet cannot move the dollars. Under Frames, a payments app can attach a sponsor VERIFY, pay the ether fee, and collect USDC from the user in the same atomic batch. If the swap fails, the approval and the USDC payment revert with it.

Vitalik Buterin, writing through the design in February 2026, sketched the same pattern with RAI instead of a dollar token. “You use a paymaster contract, which is a special-purpose onchain DEX that provides the ETH in real time,” he wrote. The frames check the sender, check the paymaster, then execute.

A USDC FEE, FRAME BY FRAME

1. VERIFY, sender: Check the user’s signature and approve execution.
2. VERIFY, sponsor: Check the sponsor and approve payment of the ETH fee.
3. SENDER: Run the user’s calls, a transfer, a swap, or both as an atomic batch.
4. SENDER: Send the sponsor USDC equal to the quoted fee.
5. DEFAULT: Let the sponsor run a post-op and refund any overcharge.

The public-mempool shape is stricter than that cartoon. A sponsor that only checks authorization data, not the user’s live USDC balance, can be left holding an ETH bill if the user drains the token before inclusion. A trustless balance check is valid at consensus, but it reads external token storage and may have to leave the simple public-mempool subset. The fee token is a product choice sitting on top of ether settlement, not a replacement for it.

Gas Demand Shifts to Wallets and Payment Apps

The first reading of the headline treats Frames as a death sentence for ETH utility. That reading skips the invoice. Validators still receive priority fees in ETH. The EIP-1559 base fee still burns in ETH. Someone still has to buy that ether.

What goes away is the stranded sliver. Millions of wallets keep a little ETH they never wanted, because a USDC balance is otherwise stuck. That bid is messy, constant, and price-insensitive. After Frames, the buyer is a wallet, a payments app, or a dedicated sponsor that already runs an ETH inventory, converts inbound stablecoins, and treats gas as a cost of goods.

Demand does not vanish. It changes shape. Fewer buyers, larger tickets, better hedging. ETH becomes the settlement asset behind a dollar interface, closer to how card networks sit behind a checkout button. If volume rises because sending dollars no longer requires a second token, burn can rise with it. If volume does not rise, the lost retail top-ups are a real bid that does not come back.

The people who capture the user are the sponsors who quote the fee in USDC, USDT, or the app’s own token. The people who still need ETH are those same sponsors, plus stakers and whoever else wants ether for its own sake.

Public Mempools Without Bundlers or Relayers

None of this UX is new on Ethereum. ERC-4337, live since 2023, already lets a paymaster front native gas and charge the user in an ERC-20. EIP-7702, shipped in Pectra, lets an ordinary account borrow smart-account behavior without moving funds. Coinbase’s paymaster docs describe the same pitch in one line: developers pay gas fees for users.

Those paths live beside the protocol. User operations go through an alt-mempool. Bundlers package them. A singleton EntryPoint contract sits in the middle. Reputation rules try to keep that extra stack from becoming a denial-of-service hose. Apps that want “gasless” UX today pay for that infrastructure, or they rely on a relayer.

EIP-8141’s motivation text is explicit on that point: alternative fee payment should work “without centralized, third party relayers.” lightclient, a co-author, put relayer-less operation in the public mempool on the design-goal list, next to sender and payer separation, key rotation, and privacy-pool support. Frames are ordinary transactions. They propagate like other transactions. FOCIL’s inclusion lists can cover them the same way they cover anything else eligible.

EOAs get a fallback without deploying code and without an EIP-7702 delegation. A VERIFY frame can use the secp256k1 signature already on the transaction and call APPROVE natively. P256 passkeys are a protocol-validated scheme too, at 6,700 gas against 2,800 for secp256k1. Custom schemes ride in an ARBITRARY signature entry and get checked in account code.

Two S-Tier Items Define the Hegotá Fork

ethereum.org lists the Hegotá upgrade expected in Q2 2027, with the date not yet confirmed. The name joins Heze, the consensus-layer upgrade, and Bogotá, the execution-layer upgrade. It follows Glamsterdam, which the Protocol cluster is planning around December 2026. Client teams can start Hegotá work in late Q4 2026.

FOCIL, EIP-7805, is the other S item. It lets a validator committee publish inclusion lists that builders are expected to honor, so a valid transaction is harder to keep out of a block. Frames without FOCIL would still need someone willing to include an unusual validation path. FOCIL without Frames leaves privacy and sponsored flows leaning on relayers. The cluster wants them tested together.

HEGOTÁ’S LOCKED CORE

Keyed nonces, average 3.12 from 8 grades, let many users share one sender without blocking each other’s nonces. Recent roots, 2.86 from 7, let a private transaction prove a fact about recent state in a form attesters can check. VOPS profiles, 3.5 from 4, define which transactions FOCIL must treat as eligible. The A-tier rule is that those items ship with the S items unless delivery forces a cut, and they are cut only after everything below them.

The cluster is hosting a Reddit AMA on r/ethereum on September 16 at 2pm UTC to take challenges to the grades. The specification remains a draft. Sequence, opcodes, and mempool rules can still move before mainnet.

Rotate Keys Without Moving a Single Wei

Every ordinary Ethereum account is still tied to one secp256k1 key. Lose it and the address is gone. Frames let the account set its own validation code, so a key can be rotated, a passkey added, or a post-quantum scheme swapped in without sending funds to a new address. That is the feature the S-grade note actually names.

The Protocol cluster’s north star is an L1 that is quantum-resistant across all three layers, execution, consensus, and data, by December 2029. The date is lined up with migration targets at Google, Cloudflare, and Microsoft. Reaching it from a December 2026 Glamsterdam ships five more forks at an average 7.2 months each. Frames are the execution-layer piece of that clock, because a new signature scheme should not need its own hard fork. Consensus cryptography does not get that luxury. It changes only by fork, which is why Hegotá also starts retiring some BLS withdrawal credentials.

That quantum track sits next to the Lean Ethereum work on privacy and quantum already on the research agenda. Users will not be sending Frame Transactions on mainnet until Hegotá actually activates, and the draft can still change. The SFI vote on August 27 is the commitment to build and test them, not a live feature.

THE ROAD TO A QUANTUM-RESISTANT L1

1. January 29, 2026: EIP-8141 is filed as a draft, type 0x06.
2. March 26, 2026: All Core Developers Execution call 233 marks it considered for inclusion.
3. August 27, 2026: Call 244 schedules it for inclusion in Hegotá.
4. September 7, 2026: The Protocol cluster publishes the S-tier grades and the 2029 north star.
5. December 2026: Glamsterdam is the cluster’s planning target on mainnet.
6. Q2 2027: Hegotá is expected, with no confirmed activation date.
7. December 2029: Target for quantum-resistant execution, consensus, and data.

A payments user in 2027 may never buy ETH. The sponsor in the next frame still will, every time a dollar moves. That is the upgrade the wire summarized as stablecoin gas, and it is also the first fork Ethereum is willing to slip a calendar for rather than cut.
