There are moments in blockchain when speed is more than just an advantage—it’s the difference between profit and loss. That’s where Maximal Extractable Value (MEV) comes in.
On Solana, the concept of MEV takes on a unique form, shaped by its high throughput and parallel processing. Unlike Ethereum, where MEV focuses on transaction reordering in a mempool, Solana operates differently. Its architecture enables flash loans, arbitrage, and instant transaction sequencing to happen faster and with less friction.
On Ethereum, the public mempool lets searchers observe pending transactions, spot opportunities, and strategically place their transactions. It’s a race of gas fees and timing, where visibility is everything.
Solana, on the other hand, eliminates the traditional mempool. Thanks to its deterministic leader schedule powered by Proof of History (PoH), transactions are sent directly to the appointed leader for that slot. This structure prioritizes speed and parallelism, where transactions don’t just wait their turn—they are processed simultaneously across multiple cores through Sealevel.
Below is a side-by-side comparison to highlight these differences:
Aspect | Ethereum | Solana |
---|---|---|
Transaction Handling | Single-threaded, sequential processing | Multi-threaded parallel processing (Sealevel), allowing thousands of transactions at once |
Mempool Visibility | Public mempool where transactions wait before execution | No traditional mempool; transactions sent directly to the appointed leader |
Transaction Ordering | Validators reorder transactions based on gas fees (e.g., front-running, sandwiching) | Deterministic leader schedule minimizes arbitrary reordering by validators |
Arbitrage Opportunities | Typically executed through gas price competition | Executed via speed and latency, requiring low-latency infrastructure |
Flash Loans | Commonly used for instant liquidity in arbitrage or liquidation | Available but executed faster due to Solana's low-latency design |
Consensus Mechanism | Proof of Stake (PoS) with block-by-block mining cycles | Proof of History (PoH) + Proof of Stake, with predefined leader slots |
Latency Sensitivity | Milliseconds matter, but gas price is the primary battle | Microseconds matter; speed is crucial due to instant forwarding to leaders |
Infrastructure Edge | MEV searchers rely on optimized gas fees and mempool monitoring | MEV searchers need dedicated RPC nodes, direct validator connections, and microsecond latency |
Unlike Ethereum's public mempool, Solana relies on private relays and direct routing to validators. This shifts the competition from gas bidding to low-latency infrastructure.

Unlike Ethereum, where MEV is primarily gas-based, Solana's high throughput and parallel processing create new ways for searchers to extract value.
One of Solana's defining features is its Sealevel parallel processing engine. Unlike Ethereum’s single-threaded EVM, Solana processes thousands of transactions simultaneously, as long as they don’t touch the same state. This is possible because each transaction on Solana must declare which accounts it will interact with before execution. If there’s no overlap, those transactions can be executed in parallel.
To put it into perspective:
Imagine a bot spotting a price discrepancy between two Solana DEXes—say, Orca and Raydium. It can execute an arbitrage trade across both simultaneously, rather than waiting for confirmation from one before acting on the other. This gives MEV searchers a massive edge in capitalizing on micro-arbitrage opportunities that would otherwise be impossible on single-threaded chains like Ethereum.
Solana also supports flash loans, which allow MEV searchers to borrow large amounts of liquidity for a single transaction, execute arbitrage or liquidation strategies, and repay the loan—all within the same block. If any step fails, the entire transaction is rolled back, and no money is lost.
Here’s why this matters:
A common strategy is a triangular arbitrage:
All of this happens in a single atomic transaction—if one step fails, the whole process rolls back without any loss.
Even without a public mempool, transaction ordering remains a critical battleground for MEV on Solana. Here’s how it works:
For example, if a bot detects a large trade about to happen on Orca, it can submit a backrun transaction with a higher priority fee to execute right after the initial trade. The bot effectively captures the price rebound before the market corrects.
This mechanism is why MEV searchers increasingly rely on dedicated RPC nodes with direct validator access—latency is everything. A 50ms delay could mean the difference between a successful backrun and a missed opportunity.
Arbitrage is the bread and butter of MEV, and Solana’s architecture supercharges it. With parallel processing and low transaction costs, searchers can:
Large trades on platforms like Raydium have been known to cause brief price spikes, occasionally leading to discrepancies with listings on other exchanges like Serum.
To succeed in this high-speed environment, searchers need optimized infrastructure:
This is why infrastructure providers like RPC Fast are crucial. By offering low-latency, high-throughput RPC nodes, they give searchers the edge to react in real-time. A standard public RPC might be enough for regular users, but for MEV extraction, it’s simply not fast enough.
"The race for MEV depends on infrastructure that ensures faster transactions and higher success rates."

MEV on Solana has grown rapidly alongside the network's expansion. With its high throughput, low latency, and parallel processing capabilities, Solana has become a playground for MEV searchers. Unlike Ethereum, where MEV is largely visible in the mempool, on Solana it happens in near-invisible microseconds. The network's architecture favors speed and concurrency, allowing MEV searchers to execute complex strategies almost instantly.
However, Solana's high-speed environment also comes with challenges. Over 60% of attempted trades fail due to network congestion, latency issues, or competition. This high failure rate emphasizes the need for optimized infrastructure.
MEV activities significantly contribute to Solana's transaction volume and validator revenues, showcasing how critical infrastructure is for searchers. Key strategies include:
Optimized RPC connections, low-latency access to validators, and real-time state monitoring are critical for successful execution in Solana's competitive MEV landscape.
If there’s one name that comes up consistently in the world of Solana MEV, it’s Jito Labs. They pioneered the concept of MEV bundles on Solana, allowing searchers to submit tightly packed groups of transactions to validators running the Jito-Solana client.
This bundling model has made Solana’s MEV extraction more structured and competitive. Validators are directly incentivized to include profitable bundles, and searchers are guaranteed execution if their bid is high enough.
In fact, in Q1 2025, Jito bundles accounted for over 22% of total validator rewards, dominating non-base-fee revenue streams and cementing its role as a key driver of MEV on Solana.
The rise of MEV on Solana has triggered a sort of infrastructure arms race. Searchers looking to stay competitive have been forced to:
It’s no longer enough to simply write good arbitrage logic—you need the fastest path to validators, low-latency messaging, and instant access to on-chain events.
By bypassing the congestion of public RPC endpoints, searchers can send transactions directly to the leader in real-time, shaving off milliseconds that make the difference between winning or losing an MEV race.
The ecosystem has also seen a surge in open-source and proprietary MEV bots specifically optimized for Solana’s architecture:

A recent deployment with Magneta Labs showcased exactly what optimized infrastructure can achieve.
Tasked with running high-availability Solana nodes based on OVHcloud, our solution didn’t just improve stability—it redefined performance metrics. During peak trading sessions on Solend, our nodes consistently outpaced public RPC by 15% in transaction success rates.
For searchers running arbitrage cycles on Orca and Raydium, the difference was immediate: 18% lower latency meant faster execution and more opportunities captured. Missed trades turned into completed cycles. Failed attempts shrank, and throughput increased.
For Magneta Labs, this wasn’t just technical improvement—it was a competitive advantage. While public RPCs battled congestion, their strategies executed flawlessly, capturing more MEV with precision timing. This is what happens when speed is backed by real infrastructure, purpose-built for Solana’s demands.
Now that you understand how MEV works on Solana, the real question is: why do you need it?
Optimized infrastructure like RPC Fast is not just a technical upgrade—it’s a gateway to capturing more value, more often.
However, with the right RPC setup and optimized node access, the need for brute-force spamming is drastically reduced, resulting in cleaner, more efficient blockspace usage.
