**What is Maximal Extractable Value (MEV) and How Does It Affect Crypto Users?**
Maximal Extractable Value (MEV) refers to the profit that miners or validators can extract by reordering, including, or censoring transactions within a blockchain block. This practice creates information asymmetry in transaction ordering, impacting all electronic markets, including crypto.
MEV effectively imposes a hidden tax on retail crypto users through tactics like sandwich attacks, where transactions are front-run to manipulate prices. These exploitative methods increase costs and contribute to higher volatility, ultimately hurting retail traders.
**Why Do Institutions Avoid DeFi?**
Financial institutions tend to avoid decentralized finance (DeFi) due to the risks associated with front-running and public order flow visibility. Without adequate privacy protections, large institutional orders become predictable targets for exploitation, eroding trust and profitability. This lack of participation leads to reduced liquidity and higher volatility, ultimately impacting the entire ecosystem’s efficiency.
**The Scale of MEV in Crypto Markets**
Recent analyses reveal that approximately 24% of Ethereum blocks are affected by MEV activities. According to data from the European Securities and Markets Authority (ESMA), revenues from various MEV methods reach billions of dollars annually across networks like Ethereum, highlighting the substantial losses borne by ordinary crypto users.
**How Can Trusted Execution Environments Prevent MEV Exploitation?**
Trusted Execution Environments (TEEs) offer a promising solution by enabling private transaction processing. TEEs encrypt client-side orders and decrypt them only within a secure enclave **after** sequencing, eliminating the visibility of order flow before execution.
This mechanism makes front-running impossible and protects against manipulations such as sandwich attacks. As Aditya Palepu, CEO of DEX Labs and lead contributor to the decentralized crypto derivatives exchange DerivaDEX, explains:
> “What makes them really powerful is that they can process orders privately. 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.”
By handling trades securely through a funded vault or similar setup, TEEs address the core issues of information asymmetry that enable profit extraction in electronic markets.
**MEV’s Impact: A Barrier to Market Adoption**
MEV has become a fundamental part of crypto infrastructure, fueling debates about its role in promoting centralization and hindering widespread adoption. Its presence discourages institutional involvement, which is crucial for improving market stability and liquidity.
Shielding transactions from public view via TEEs could level the playing field and encourage broader participation. This shift holds the potential to unlock trillions in capital inflows and foster healthier, fairer markets across all user segments.

### Frequently Asked Questions
**What causes Maximal Extractable Value (MEV) to act as a hidden tax on retail users?**
MEV arises because transaction details are publicly broadcast **before** execution. Sophisticated actors can reorder transactions to profit through arbitrage or liquidations, increasing slippage and fees for retail traders. Studies show retail users bear up to 80% of these hidden costs without any recourse.
**How does lack of privacy in DeFi deter financial institutions from participating?**
Financial institutions require confidentiality to protect their trades from front-running and market manipulation. Without privacy tools like TEEs, exposing large orders leads to predictable exploitation. This erodes trust and profitability, creating barriers that prevent institutions from building essential market infrastructure, which hurts ecosystem stability and liquidity.

### Key Takeaways
– **MEV as a Barrier to Adoption:** Publicly broadcasting transactions enables profit extraction mechanisms that discourage institutional participation, leading to thinner markets and higher costs for retail users.
– **Role of Trusted Execution Environments:** TEEs securely handle orders in private, preventing manipulative attacks like sandwich trading and fostering fairer DeFi participation.
– **Impact on Market Health:** Institutional involvement contributes to market stability and liquidity; mitigating MEV could unlock enormous capital inflows to crypto markets globally.

### Conclusion
Maximal Extractable Value (MEV) poses a significant challenge to the health and inclusivity of crypto markets by creating information asymmetry that harms retail users and deters institutions. Trusted Execution Environments represent a powerful tool to neutralize MEV exploitation by safeguarding transaction privacy and making front-running impossible.
By embracing such solutions, the crypto ecosystem can move toward fairer, more efficient markets—encouraging broader adoption, boosting liquidity, and reducing volatility for all participants.
