Maximal Extractable Value (MEV) in crypto acts as a hidden tax on retail users by allowing miners or validators to reorder transactions for profit, deterring financial institutions from DeFi adoption and increasing costs through manipulation like sandwich attacks.
-
MEV creates information asymmetry in transaction ordering, impacting all electronic markets including crypto.
-
Institutions avoid DeFi due to front-running risks from public order flow, hurting retail liquidity and raising volatility.
-
Trusted execution environments enable private transaction processing, making front-running impossible and fostering fairer markets with 24% of Ethereum blocks affected by MEV in recent analyses.

What is Maximal Extractable Value (MEV) and How Does It Affect Crypto Users?
Maximal Extractable Value (MEV) refers to the profit miners or validators can extract by reordering, including, or censoring transactions within a blockchain block. This process imposes a hidden tax on retail crypto users through practices like sandwich attacks, where transactions are front-run to manipulate prices. Financial institutions are alienated from decentralized finance (DeFi) due to these vulnerabilities, ultimately increasing costs and reducing market efficiency for everyone involved.
How Can Trusted Execution Environments Prevent MEV Exploitation?
Trusted execution environments (TEEs) process transactions privately, encrypting orders client-side and decrypting them only within a secure enclave after sequencing. This approach eliminates the visibility of order flow before execution, making front-running impossible and protecting against market manipulations such as sandwich attacks. According to data from the European Securities and Markets Authority (ESMA), MEV-related activities influence a significant portion of blockchain operations, with revenues from various MEV methods highlighting the scale of potential losses—estimated at billions annually across networks like Ethereum.
Aditya Palepu, CEO of DEX Labs and lead contributor to the decentralized crypto derivatives exchange DerivaDEX, emphasizes the power of TEEs in maintaining privacy. “What makes them really powerful is that they can process orders privately,” Palepu stated. “So your trading intentions aren’t broadcast to the world before execution. They’re encrypted client-side, and they’re only decrypted inside the secure enclave after they’re sequenced.” This mechanism uses a funded vault or similar setup to handle trades securely, addressing inherent issues in all electronically traded markets where information asymmetry allows for profit extraction.

Industry experts note that MEV has become a core part of crypto infrastructure, sparking debates on its role in driving centralization and stifling adoption. By shielding transactions from public view, TEEs could level the playing field, encouraging broader participation while reducing the extractive practices that currently dominate.
Frequently Asked Questions
What Causes Maximal Extractable Value (MEV) to Act as a Hidden Tax on Retail Users?
MEV arises when transaction details are broadcast publicly before execution, allowing sophisticated actors to reorder them for profit through arbitrage or liquidation. This results in higher slippage and fees for retail traders, effectively taxing their trades—studies show retail users bear up to 80% of these costs without recourse, as reported by blockchain analytics firms.
How Does Lack of Privacy in DeFi Deter Financial Institutions from Participating?
Financial institutions require confidentiality to avoid front-running and market manipulation risks inherent in public blockchains. Without privacy tools like TEEs, exposing large orders leads to predictable exploitation, eroding trust and profitability—Palepu notes this creates barriers that prevent institutions from building essential market infrastructure, ultimately harming the entire ecosystem’s stability and liquidity.
Key Takeaways
- MEV as a Barrier to Adoption: Broadcasting transactions enables profit extraction that discourages institutions, leading to thinner markets and higher retail costs.
- Role of Trusted Execution Environments: These secure processors ensure private order handling, blocking sandwich attacks and fostering fairer DeFi participation across all user levels.
- Impact on Market Health: Institutional involvement stabilizes volatility and liquidity; addressing MEV could unlock trillions in capital inflows to crypto markets.

Conclusion
Maximal Extractable Value (MEV) continues to challenge the crypto ecosystem by imposing extractive costs on retail users and preventing financial institutions from fully engaging with DeFi. Solutions like trusted execution environments offer a pathway to private, secure transactions that could mitigate these issues, promoting greater market vibrancy and inclusivity. As the industry evolves, prioritizing fairness in transaction processing will be key to sustainable growth and widespread adoption in the coming years.
