Key Points
Unlike Bitcoin, Ethereum and Solana use a pool of validators for transaction confirmation. This allows users to expedite transactions by paying higher fees.
Impact of MEV Bots on Gas Fees
At the protocol level, prioritizing transactions based on gas fees has led to the rise of complex Maximal Extractable Value (MEV) bots on Solana and Ethereum. These bots exploit the system and have become a significant factor in the ongoing debate about gas fees.
The debate surrounding validators, gas fees, and the impact of MEV bots on Solana and Ethereum is escalating. Mert Mumtaz, the co-founder of Solana RPC provider Helius, highlighted the role of a single sandwich bot, Jaredfromsubway, which was the top source of gas fees on Ethereum.
This bot alone is responsible for a staggering 142 ETH per day, surpassing fees paid by major players like Coinbase.
Mumtaz argues that the Ethereum Foundation, by not subsidizing validators, is indirectly endorsing MEV bot operators to continue “robbing” retail traders. Ethereum, notorious for its scalability issues, is the most expensive network to transact on. The proliferation of MEV bots, as seen with Jaredfromsubway, could be contributing immensely.
In light of this, Mumtaz points out that Ethereum developers have failed to address the MEV menace despite years of dedicated research and solutions at various protocol levels.
Mumtaz believes Solana is doing much better in handling the impact of MEV bots on gas fees. Solana currently and actively subsides most of its validators. The subsidy, absent in Ethereum, penalizes operators engaging in MEV operations, discouraging the behavior.
However, some argue that Solana’s approach only offers “band-aid” solutions. They claim that Solana actually “invented” and “weaponized” MEV. There are other claims that SOL holders like Multicoin Capital prioritize chains based on their MEV capture potential.
Recently, some of these subsidized validators were caught enabling MEV to “sandwich” users. The Solana Foundation swiftly removed their stake, but it remains to be seen whether MEV attacks will stop.
