EU Declares MEV Illegal Under New Crypto Market Regulations

The European Union (EU) has labeled Maximum Extractable Value (MEV) as illegal market abuse under its Markets in Crypto-Assets (MiCA) regulation.

This significant move aims to curb sophisticated market manipulation and allow all participants to engage fairly.

EU’s Regulatory Measures and Definitions

MEV refers to the profit block producers can gain by reordering, including, or excluding transactions within a block. This manipulation can make the system unfair, giving an advantage to those with more resources and technical knowledge. Patrick Hansen, Circle’s EU Strategy and Policy Head, emphasized the issue’s severity.

“The well-known MEV, where a miner/validator reorders transactions to front-run specific transactions and make a profit, clearly suggests market abuse,” he explained .

The European Securities and Markets Authority (ESMA) outlined  measures to tackle MEV. According to ESMA, trading platforms are required to monitor and report suspicious MEV activities , and the proposed standards include detailed procedures for detecting exploits.

ESMA’s draft template is not final and might undergo modifications in the coming months. The regulator set a June 25 deadline for stakeholders to submit feedback on the draft standards​​.

MEV has been contentious in the blockchain community since 2018, inflating transaction costs, undermining network security , and promoting unfair trading. By reordering transactions, miners capture value, leading to higher fees and inefficiencies​​.

Prominent faces of the crypto industry are suggesting various ways to solve this problem. Vitalik Buterin, Ethereum’s co-founder, recently  addressed  MEV issues. He assumed reducing MEV through protocols that hide transaction details until confirmed and separating transaction proposers from block builders to limit unfair value extraction.

The US financial regulators are also aware of the MEV threat. The US Department of Justice (DOJ)  announced  the arrest of two brothers for using MEV tactics to steal $25 million from Ethereum. They face charges of fraud and money laundering, with potential 20-year prison sentences.

ESMA’s draft standards propose a collaborative enforcement approach, urging cooperation between authorities within and outside the EU. Once finalized, these standards will shape the EU’s crypto regulatory environment and set a precedent for other jurisdictions.
