Vitalik Buterin proposes Ethereum upgrade to overhaul transaction signing and fee structure

On September 6, 2026, Vitalik Buterin published Ethereum Improvement Proposal (EIP) 8141 for the Hegotá upgrade. The proposal introduces frame transactions bundling up to 64 actions, detaches accounts from seed phrases to allow key rotation, and enables gas fee sponsorship via paymasters. It also integrates the P256 signature scheme to support passkeys and prepare for post-quantum cryptography. No activation date is set, as the Glamsterdam upgrade launches first in Q4 2026.

EIP-8141 frame transaction proposal

• ▪Under the EIP-8141 proposal, a single frame transaction can carry up to 64 steps in a fixed order, with the entire batch failing if any single step fails.
• ▪Vitalik Buterin published an updated Ethereum Improvement Proposal (EIP) 8141 on September 6, 2026, to overhaul how wallets sign, batch, and pay transactions for the upcoming Hegotá upgrade.

Wallet key rotation mechanism

• ▪The key rotation mechanism in the EIP-8141 proposal is designed to prevent the loss of funds when an Ethereum user loses their 12-word seed phrase backup.
• ▪The EIP-8141 proposal detaches an Ethereum account from its original key, allowing wallets to rotate keys or rebuild access through a second device or trusted contact.

Paymaster gas fee sponsorship

• ▪Under the paymaster system in the EIP-8141 proposal, decentralized applications can absorb transaction costs as a customer acquisition expense.
• ▪The EIP-8141 proposal introduces paymasters that allow applications to pay a user's gas fees, enabling newcomers to transact before buying Ethereum.

P256 passkey signature support

• ▪The EIP-8141 proposal adds support for P256, the signature scheme behind passkeys and mobile phone security chips, to Ethereum transaction signing.
• ▪The integration of the P256 signature scheme in the EIP-8141 proposal is designed to make transaction signing compatible with standard smartphone hardware security.

Post-quantum cryptography preparation

• ▪The authors of the EIP-8141 proposal describe the addition of the P256 signature scheme as an off-ramp toward post-quantum cryptography rather than a finished quantum fix.
• ▪Ethereum co-founder Vitalik Buterin previously sketched ideas for post-quantum cryptography in a lean Ethereum roadmap published in July 2026.

Ethereum scaling roadmap

• ▪Ethereum co-founder Vitalik Buterin aims to move Ethereum toward a Bitcoin-like design where simple, predictable transactions incur the lowest gas fees.
• ▪Ethereum client teams have set no activation date for the EIP-8141 proposal, and the Glamsterdam upgrade with its gas limit push is scheduled to launch first in Q4 2026.

Debatable claims

• ▪Ethereum should adopt a Bitcoin-like transaction design to lower fees
• ▪Decentralized applications should subsidize user transaction fees
• ▪Ethereum should replace seed phrases with key rotation and social recovery
