In today's multi-chain blockchain era, the evolution from simple ledgers to complex smart contract networks has created a volatile economic space. There, Maximal Extractable Value (MEV) – or maximum extractable value – has become a "game" of technical minds and profit-hunting algorithms.
1. The Nature and Evolution of MEV
MEV is a measure of the profit that block producers (miners in PoW or validators in PoS) can obtain by reordering, adding, or removing transactions in the blocks they create.
Terminological shift through the ages:
The PoW Era (Before 2022): Called Miner Extractable Value. The power to extract value lies in the hands of miners with specialized machinery, competing mainly based on gas fees (PGA) and computing power.
PoS Era (Current): Called Maximal Extractable Value. As Ethereum moves to Proof of Stake, the power belongs to validators, prospectors, and block builders through the role separation mechanism (PBS) and block auctions via MEV-Boost.
Enshrined (Future) Era: Called Enshrined MEV. This is the stage of directly integrating the auction mechanism into the protocol (ePBS) and surplus profit destruction mechanisms (MEV-Burn) to ensure fairness.
Currently, MEV has become an indispensable part of the revenue structure of validators. With support from experts like Tan Phat Digital in building in-depth content and marketing strategies, users and investors can better understand how MEV affects the market through phenomena such as price slippage or rising gas fees.
2. Modern MEV Supply Chain
MEV mining is currently an industrialized process with a clear division of labor:
Searchers' activities
Searchers are opportunistic "hunters" in the mempool (pool waiting for transactions). Key activities include:
Mempool Monitoring:Using high-speed bots to scan any unconfirmed transactions, looking for arbitrage or liquidation opportunities.
Trading Simulation: Before executing, searchers must simulate the network state to ensure their bundle is profitable after deducting fees gas.
Bundles Aggregation: Builders receive thousands of bundles from many different searchers.
Revenue Optimization: They use complex algorithms to arrange bundles and retail transactions so that the total block value (including tip fees and MEV) is highest.
Bertrand Competition: Builders participate in a fierce auction with each other to have their block chosen by a validator (proposer) to be posted to the main chain.
Relayers: Is a trusted intermediary that helps protect builders from validators stealing block content before signing the confirmation.
Proposers (Validators): As a stake holder, simply choose the block with the highest payout from the relay to optimize profits without needing to build the block yourself.
Arbitrage: Exploits asset price deviations between DEXs such as Uniswap and Sushiswap. This is a "benign" form that helps synchronize prices across the ecosystem.
Front-running: The bot detects a large buy order in the mempool and sends a similar order with a higher gas fee to be executed first, then sells immediately after the user order is completed to take profit.
Sandwich Attacks: Combine front-running and back-running. The bot buys first to push up the price, the user buys at a high price, and the bot sells immediately to profit from the user's price slippage.
Liquidations: Searchers compete to execute the first liquidation order on undercollateralized loan positions to receive rewards from the protocol.
Time-bandit Attacks: When the MEV value is too large, Miners or validators may attempt to reorganize the chain (reorg) to re-mine old blocks to appropriate profits.
The Peraire-Bueno brothers' $25 million exploit (April 2023): Two MIT alumni brothers manipulated the MEV-Boost protocol of Ethereum to steal $25 million in cryptocurrency in just 12 seconds. They used a "bait" tactic to trick other MEV bots, then replaced them with their own transactions via fake signatures sent to the relay.
The "arsc" bot on Solana ($30 million in 2 months): A notorious MEV bot on the Solana network amassed $30 million in profits in a short period of time by performing sandwich attacks repeatedly during periods of market volatility strong.
Sandwich Tragedy on Uniswap v3 (March 12, 2025): A trader lost nearly 98% of his trade value trying to convert 220,764 USD stablecoins. A MEV bot discovered and executed the clamp, causing the trader to only receive back about 5,271 USDT, while the attacker paid a tip fee to the builder of up to 200,000 USD to execute this order.
Jaredfromsubway.eth: One of the "legends" of MEV on Ethereum with a net profit of millions of USD per day thanks to the absolute dominance in gas fee auctions at the High liquidity trading platform.
Features: Based on public mempool and Flashbots MEV-Boost infrastructure.
Status: About 91% of blocks are completed by Flashbots professional MEV agent.
Solution: Moving to ePBS (enshrined PBS) to eliminate intermediaries.
Features: No traditional public mempool; Transactions are sent directly to the Leader.
Status: MEV mainly manifests itself through spamming the network or through the Jito-Solana client.
Solution: Jito-Solana currently accounts for more than 90% of the staking rate, helping to redistribute MEV to stakers in a more transparent way.
Features: Strong increase thanks to the appearance of Ordinals, Runes and BRC-20.
Status: There was a time when transaction fees from these metaprotocols accounted for 60% of miner revenue.
Solution: Miners use RBF (Replace-by-Fee) to prioritize high-value rare asset minting transactions.
MEV-Boost: Middleware software that helps validators connect to the global builder market, increasing staking profits by about 60% in some cases.
Jito-Solana (Solana): The bundle system helps reduce network spam and ensures complex transactions (like arbitrage) are executed atomically (successfully all bundle or nothing).
TEE Infrastructure (BNB Chain): Uses hardware-level security (Trusted Execution Environment) to auction blocks in a cryptographic environment, preventing any form of data preview to perform sandwich attacks.

MEV strategies range from those that make markets more efficient to attacks that harm end users:
4. Case Study: Real-life shocking MEV attacks
To understand the extent of MEV's impact, let's look at real figures and events in the period 2023-2025:

Tan Phat Digital recognizes that, similar to optimizing website performance, optimizing MEV requires a balance between profit and user experience. We help businesses build a solid technical foundation to adapt to the latest Web3 standards.
7. Frequently Asked Questions (FAQs) about MEV
Can MEV be completely prevented? MEV cannot be eliminated because it is an inevitable consequence of control over transaction ordering. However, the negative impact can be minimized with tools such as Private RPC (Flashbots Protect) which prevents transactions from being seen by bots in the public mempool.
What benefits does MEV bring to the network? MEV is not completely bad. Arbitrage bots keep asset prices on DEXs consistent, and liquidation bots help ensure liquidity for lending protocols when the market fluctuates.
How do regular users lose? The biggest damage is the higher than expected slippage and gas fees being pushed up due to MEV bots fiercely bidding for space in the block.
Why does MEV lead to centralization? Because MEV mining requires huge technical infrastructure and capital. Large builders with advantages in latency and order flow will easily dominate the market, making it difficult for small validators to compete if they do not participate in solutions like MEV-Boost.
