EU Targets MEV Abuse in Crypto with New MiCA Rules

Highlights:

  • The EU’s new MiCA regulation targets the elimination of MEV to ensure fair cryptocurrency trading.
  • MultiversX stands out by preventing transaction reordering and aligning with EU standards for market fairness.
  • ESMA’s draft standards call for detailed reporting on MEV, highlighting the regulatory challenges in the crypto sector.

The European Union is addressing concerns over Maximum Extractable Value (MEV) within the cryptocurrency market. This practice, where miners or validators manipulate transaction orders for profit, is now under scrutiny through the Markets in Crypto-Assets (MiCA) regulation.

MultiversX Advocates for Fair Practices

Unlike other blockchains that have endorsed or even incentivized MEV for economic benefits, MultiversX has taken a clear stance against it. This platform ensures that its validators cannot reorder transactions. 

MultiversX randomizes transactions, effectively preventing MEV attackers from paying higher fees to gain transaction precedence. Although network spamming remains a potential issue, the control over transaction sequencing does not rest in the hands of a few.

EU’s Legal Framework and Its Implications

The EU Securities & Markets Authority (ESMA) has recently issued its third consultation package, which includes proposed technical standards for implementing MiCA’s high-level rules. One significant aspect of these standards is the focus on detecting and preventing MEV-related market abuses. 

Under the proposed regulations, all regulated crypto entities in the EU, such as exchanges and brokers, must detect and report any instance of MEV through detailed “suspicious transaction or order reports” (STORs).

Handling such regulations could pose substantial challenges. With each MEV instance requiring a detailed report, the administrative burden on crypto businesses could be immense. ESMA’s draft suggests that international cooperation is crucial for enforcing these standards. This could lead to cross-border investigative and enforcement actions against parties involved in MEV.

These standards are still in the draft phase, but they are expected to be finalized soon. ESMA has set a June 25 deadline for stakeholders to provide feedback. Participation in this consultation is vital for stakeholders in the cryptocurrency industry. This is especially important for those who handle or are impacted by MEV.
