EIP-8429 Seeks to Increase Fees to Curb 'Manipulative' Bots on Ethereum

• 50% of the surcharge is immobilized, and the block producer receives nothing.
• A similar rule operates at the token level on Robinhood Chain since September 28.

The developer identified as <> presented the Ethereum Improvement Proposal (EIP) number 8429 on September 29, 2026.

The document argues that the repetition of transactions is priced below its real cost, thus proposing that the nth call to a registered smart contract pays an extra gas amount that scales quadratically.

The initiative arose from observing activity on the recently launched Robinhood Chain. The proposal's author detected that just minutes after the launch of a token, a group of wallets opened multiple liquidity pools with unusual fee levels and operated the asset block by block.

According to collected data, transactions from a single launch platform accounted for 42% of all gas fees on the chain. Within a 24-hour window, 130 out of 3,466 launches were affected by these fund groups, allowing automated operators to extract value using ordinary buyers as exit liquidity.

To disincentivize this practice, EIP-8429 requires accounts to be irrevocably registered for the surcharge to apply to recurring calls. The counter for these calls will be stored in the network client's memory. Additionally, a second, slower counter is defined to evaluate whether the same sender returns to interact with the account within a week, ultimately charging the higher amount between both.

To prevent any actor from artificially generating these operations and capitalizing on the collection, 50% of the extra gas remains in a deposit with no withdrawal possibility, the other 50% is locked in the address designated by the contract, and the block producer receives no reward.

Thus, a user making a single purchase does not pay surcharges, while a machine referencing the same contract fifty times in a block will face maximum quadratic costs. The author confirmed that a version of this rule has been active on Robinhood Chain since September 28, 2026, where tests showed that automated wallets were charged 632 basis points of volume, while the rest of the participants paid only 19 basis points.

In terms of markets and trading, these technical optimizations accompany a scenario that analysts consider positive for the cryptocurrency ether (ETH). Today, analyst Michaël van de Poppe estimated that the recent network updates are <> and stated that the asset shows ---in his opinion--- stronger behavior than bitcoin (BTC).

According to Van de Poppe, ETH is expected to break its current resistance level to target the mark of USD 3,000.

In the long term, tariff optimization proposals like EIP-8429 align with the structural transformation of the network described by Vitalik Buterin.

As reported by CriptoNoticias on September 27, the co-founder of Ethereum assured that the network will cease to be a blockchain in the style of Bitcoin to become a <> by 2030.

In this future architecture, Buterin projects that the same volume of computation will cost much more if concentrated on opaque serial transactions. Although Buterin does not specifically name this proposal, it represents a scenario where the increased cost for recurring calls proposed by EIP-8429 would have a direct technical fit to preserve the performance and scalability of the system.
