MEV Definition: What is Miner Extractable Value?
Miner Extractable Value (MEV) refers to the profit miners or validators can earn by reordering, inserting, or censoring transactions within a block. On Solana, this often manifests as sandwich attacks that impact token launch traders. Understanding MEV is crucial for creators and traders to protect their transactions and maximize returns.

What is MEV? The Core Concept
Beyond simple transaction fees lies a hidden economy of profit extraction.
Miner Extractable Value (MEV) represents the total value that can be extracted from block production by manipulating the order of transactions. While originally "Miner" Extractable Value from Proof-of-Work blockchains, the term now broadly applies to validators in Proof-of-Stake networks like Solana. The entity producing the block has the final authority on transaction sequence, creating profitable opportunities at the expense of regular users.
On Solana, MEV is particularly active in the mempool for new token launches. Bots scan for large buy orders, then place their own transaction before it (front-run) and after it (back-run) to profit from the price impact. This is known as a sandwich attack. For a trader buying $1,000 of a new token, a successful sandwich could cost them an extra 2-5% in slippage, with that value going to the MEV bot operator.
How MEV Manifests on Solana: 4 Common Types
Here are the primary ways MEV bots operate within the Solana ecosystem, especially around new token launches:
- Sandwich Attacks: The most prevalent form. A bot detects a pending large buy in the mempool, places a buy order just before it to drive the price up, lets the victim's order execute at the higher price, then immediately sells for a profit. This can extract 3-10% from a single target.
- Arbitrage: Exploiting price differences for the same token across different decentralized exchanges (DEXs) or liquidity pools. While this can be beneficial for market efficiency, the profits are MEV. Bots compete to be first, paying higher priority fees.
- Liquidation: In lending protocols, bots monitor for undercollateralized positions. When one is detected, they race to be the first to submit the liquidation transaction, earning a liquidation fee (often 5-15%).
- Frontrunning: A broader term where a bot simply sees a profitable transaction (like a large DEX trade that will move price) and submits its own identical transaction with a higher fee to ensure it executes first.
Why MEV Matters for Crypto Creators
MEV doesn't just affect traders; it directly attacks a token's early community.
If you're launching a token on Solana, ignoring MEV can sabotage your launch's success. High MEV activity creates a poor experience for your first supporters. When early buyers are consistently 'sandwiched,' they lose a significant portion of their investment before the token even stabilizes. This leads to frustration, negative sentiment, and can kill momentum before it starts.
For example, a creator launches a token and the first 10 buyers attempt to purchase $500 each. If each trade suffers a 4% MEV loss, that's $200 of collective value extracted from your community and handed to bots before any real trading begins. This erodes trust and makes it harder to build a loyal holder base. Platforms that offer MEV protection or mitigation are directly investing in your community's success.
The Verdict on MEV for Solana Creators
Mitigation is possible and necessary for a healthy launch.
MEV is an unavoidable reality of permissionless blockchains, but its impact can be significantly reduced. Creators should not accept high MEV losses as a cost of doing business. The recommended approach is to launch on a platform with built-in MEV mitigation features.
While no solution is perfect, using a launchpad that employs mechanisms like private mempools, transaction simulation to detect sandwich attempts, or fair ordering principles can protect your initial buyers. The 0.30% per trade creator revenue on Spawned.com is more sustainable when your buyers aren't simultaneously losing an additional 3% to MEV bots. Prioritizing a launch environment that defends against extractive value protects your project's most valuable asset: its early supporters.
MEV vs. Priority Fees: What's the Difference?
One is a toll for the road, the other is a pickpocket on the road.
It's easy to confuse MEV with standard network priority fees, but they are distinct concepts that affect users in different ways.
| Aspect | MEV (Miner Extractable Value) | Priority Fees |
|---|---|---|
| Definition | Profit extracted by manipulating transaction order within a block. | A fee paid to ensure a transaction is included in the next block. |
| Who Pays | Traders/victims of attacks (indirectly via worse prices). | The user submitting the transaction (directly). |
| Who Receives | The validator (or searcher/bot) executing the MEV strategy. | The validator producing the block. |
| Purpose | Extractive profit; often harmful to users. | Network utility; pays for timely execution. |
| Example on Solana | A sandwich bot makes $50 from a trader's slippage. | You pay 0.0001 SOL to get your swap confirmed quickly. |
| Control | Users have little control; requires platform-level defenses. | Users set the fee amount when they send the transaction. |
Key Takeaway: You pay a priority fee for speed. You lose value to MEV due to market manipulation. A good launch strategy addresses both.
3 Steps Creators Can Take to Reduce MEV Risk
While you can't eliminate MEV, you can take concrete steps to minimize its impact on your token launch and community.
Launch Your Token with MEV in Mind
Build a stronger foundation by protecting your earliest supporters.
Understanding MEV is the first step toward defending against it. When you launch your token, the initial trading environment sets the tone for your project's entire lifespan. Allowing MEV bots to drain value from your supporters undermines trust from day one.
Spawned.com is built for creators who prioritize their community's success. Our Solana token launchpad integrates considerations for the realities of on-chain trading, including the pervasive threat of MEV. By launching here, you gain access to a platform designed to protect your early adopters, ensuring more of their investment goes into building your token's market—not into a bot's wallet.

Frequently Asked Questions
No, MEV is not illegal. It exists due to the inherent design of permissionless blockchains, where the block producer has discretion over transaction ordering. It's considered a market behavior within the rules of the protocol, albeit often an exploitative one. The ecosystem is developing both technical and social solutions to mitigate its negative effects.
The total value extracted via MEV is substantial. On Ethereum, cumulative MEV has exceeded $1 billion. On Solana, while harder to track precisely, estimates suggest hundreds of millions have been extracted, especially during peak meme coin and launch seasons. A single large sandwich attack can net a bot thousands of dollars from one victim.
Yes, some forms of MEV can provide network benefits. Arbitrage MEV, for instance, helps correct price differences between markets, leading to more efficient pricing across all exchanges. Liquidations MEV ensures undercollateralized loans are promptly repaid, maintaining protocol solvency. The problem arises with purely extractive MEV like sandwich attacks, which provide no net benefit.
All MEV extraction uses bots, but not all trading bots perform MEV. A simple DEX arbitrage bot that doesn't manipulate transaction order is just a trader. An MEV bot specifically uses its ability to influence or observe the pending transaction queue (mempool) to gain an unfair advantage, typically by inserting its transactions around a victim's transaction.
It can. High MEV activity at launch creates sell pressure, as bots immediately profit-take from their sandwiches. It also discourages legitimate large buyers, reducing liquidity and volume. A token known for being heavily targeted by MEV bots may struggle to attract serious investors, potentially capping its growth.
These are roles in the MEV supply chain. **Searchers** are bots/individuals who find profitable MEV opportunities (like a juicy trade in the mempool). They create a "bundle" of transactions. **Builders** are specialized nodes that construct entire block proposals to include these profitable bundles, which they then sell to **validators**. The validator includes the builder's block proposal to claim the MEV rewards, which are shared down the chain.
Spawned.com employs a guarded launch process designed to obscure initial trade intentions and reduce the visibility of transactions to public mempool snoopers. This makes it significantly harder for MEV bots to identify and target your community's early buys, helping to ensure a fairer launch where value goes to holders and creators, not extractors.
