A proposal that would let Ethereum users pay transaction fees in tokens, or have someone else pay them entirely, has been quietly advancing for months, Vitalik Buterin said on Sunday.

EIP-8141 replaces the fixed shape of an Ethereum transaction with a sequence of up to 64 "frames," each an ordinary contract call. One frame validates the transaction, another approves who covers the gas, and the rest carry out whatever the user actually wanted to do.

Splitting payment approval into its own step breaks the link between the account that signs a transaction and the account that funds it, so a wallet that only holds stablecoins could transact by paying fees in ERC-20 tokens, or an application could sponsor its users outright.

No new wallet required

That has been possible since 2023 through ERC-4337, but only by routing transactions through a separate mempool and paying third-party bundlers. Frames runs in Ethereum's public mempool, with rules written into the protocol that let nodes reason about a transaction's validation steps before accepting it.

Ordinary externally owned accounts are covered too. The specification defines "default code" that gives wallets with no contract deployed the same sponsored transactions, token-paid gas and batched calls, without users migrating to a smart account.

Frames also allows several actions to be grouped so they succeed or fail together, ending the dangling token approvals left behind when a swap reverts, and unlinks accounts from the ECDSA keys that control them, making key rotation possible for the first time.

The proposal isn’t just addressing fees. Its authors describe Frames as a “native off-ramp” from the elliptic-curve cryptography Ethereum authenticates with today, ahead of the arrival of quantum computers capable of breaking it. Co-author Matt Garnett, who writes as lightclient, notes that post-quantum signatures run to several kilobytes each, forcing the network toward signature aggregation.

The proposal has been a draft since January and is not scheduled for any upgrade. Buterin pointed to a testnet run by the ethrex client that pairs Frames with FOCIL, the censorship-resistance mechanism, to let privacy protocols operate without relayers.

Frames "should be the last transaction type we need for accounts," Garnett wrote.
