Hegotá includes work on Frame Transactions as specified in EIP-8141. The mechanism changes transaction structure so authentication, execution and gas sponsorship can be expressed more flexibly than in the legacy externally owned account flow. A practical UX case is an application or sponsor paying gas for a user, so the user does not need to acquire ETH simply to perform an initial on-chain action.
This does not mean Ethereum stops using ETH as its gas asset. Network fees still need to be paid within protocol economics; what changes is who can bear the cost and how the transaction authorizes execution. A sponsored flow can hide the need for a separate ETH purchase from the end user, while the sponsor or account-abstraction layer still funds the fee and remains subject to the fee market.
EIP-8141 introduces a frame-oriented execution model with distinct verification and authorization steps. That can support more native smart-account semantics and reduce some external machinery currently used for bundling and sponsorship. Security still depends on the correctness of account logic, sponsor policy and the exact frames permitted by a transaction.
For ETH, this is a protocol UX improvement rather than an instant change to every wallet. Even after an EIP enters upgrade scope, client implementation, testnets, audits and wallet or infrastructure adoption still matter. The useful signal is therefore actual Hegotá activation and real sponsored-transaction support, not the simplified headline that gas no longer needs ETH.
