How to Frontrun on Solana: A Step-by-Step Guide
Frontrunning is a well-known, albeit controversial, strategy in the world of cryptocurrency trading. It involves executing a trade based on the knowledge of an impending transaction, usually one that is about to impact the price of a token. Frontrunners capitalize on this knowledge by placing their own orders before the large trade is executed.
Frontrunning has been a part of crypto trading for a while, especially in high-speed environments like Ethereum and Solana. But Solana, known for its ultra-fast transaction speeds, has posed a unique challenge for frontrunners. In this guide, we’ll explore how frontrunning works, the challenges specific to Solana, and how frontrunners are currently gaining an edge in this ecosystem.
What is Frontrunning?
Frontrunning, in the context of cryptocurrency, is the practice of placing an order on a market just before a large trade is processed, anticipating that the price will move in your favor once the transaction is confirmed. It’s a form of market manipulation, and while it’s considered unethical or illegal in traditional finance, it has become a part of the game in decentralized finance (DeFi) ecosystems.
In simpler terms, if you can predict when and how a big trade will impact the price of a token, you can "front-run" that trade by executing your own order first, capturing the profit as the price moves.
Frontrunning on Ethereum vs. Solana
Frontrunning on Ethereum
In Ethereum and similar blockchains, frontrunners have a significant advantage because they can observe the public mempool, which contains pending transactions that have not yet been processed. These pending transactions are visible to anyone who monitors the network closely, allowing frontrunners to act on the information before the transaction is finalized.
Frontrunners using tools like Flashbots or MEV-Boost can access these mempool transactions and use bots to automatically place trades based on the expected price changes. The ability to see pending transactions is what makes frontrunning on Ethereum and other similar chains possible.
Frontrunning on Solana: The Challenge
Solana, on the other hand, does not provide a public mempool for its users to monitor pending transactions. This makes frontrunning much harder to execute. Solana is built for speed and efficiency, processing thousands of transactions per second. However, its design removes the traditional method of monitoring mempool data, meaning frontrunners cannot easily see what transactions are waiting to be confirmed.
Until recently, Jito offered a service that exposed pending transactions, giving frontrunners the ability to execute trades based on the unprocessed transactions. However, as of now, Jito no longer provides access to the public mempool, leaving a significant gap for frontrunners.
For this reason, getting access to unprocessed transactions on Solana is one of the most difficult hurdles for anyone attempting to frontrun on the network.
How to Get Access to Unprocessed Transactions(aka mempool) on Solana
Solana no longer has public mempool, there are a few private parties operating their own private pools, but they are not offering it to the public as they are using it to generate an absurd amount of revenue through sandwich bots.
With out direct access to mempool, the key to frontrunning on the network lies in gaining access to the transaction submission flow itself. This is the critical point in the process where transactions are pending but have not yet been added to the blockchain. There are a few ways to gain access to this data:
1. Operate a Trading Bot Others Use
One way to get closer to unprocessed transactions is by operating a trading bot that other users rely on. Some advanced trading platforms and DeFi protocols allow users to interact with a trading bot that monitors and executes orders based on market signals. By operating such a bot, you can capture transaction data before it’s finalized and get a competitive edge over other traders.
However, this method requires that your bot has direct access to the underlying transaction data, and you would need to have a large user base for it to be profitable.
2. Become an RPC Operator
Another way to access unprocessed transactions on Solana is by becoming an RPC operator. RPC nodes provide a way to communicate with Solana's blockchain, querying data about transactions and block production. By being an RPC operator, you have access to all the transactions submitted through your service.
3. Become a Validator
A more advanced and capital-intensive method is to become a validator on the Solana network. Validators are responsible for processing and validating transactions on Solana. As part of this process, validators are among the first to see unprocessed transactions before they are included in a block. This gives them an edge in knowing what trades are about to happen and potentially executing their own orders before those trades are finalized.
Running a validator requires substantial technical expertise, infrastructure, and a big staking amount on your validator to get enough leader slots. However, it offers one of the most direct ways to access the transaction submission process.
Frontrunning Using Jito: Bundling Transactions
Once you have access to unprocessed transactions, the next step is to frontrun by submitting your own bundle of transactions before the large trade is finalized.
This is where Jito—while no longer providing public mempool access—comes into play. Jito provides an advanced transaction bundling service that allows users to group multiple transactions into a single bundle, which can be processed together as part of a larger transaction. By using Jito, you can submit your own trade alongside a pending transaction in a way that gives you priority, ensuring that your trade is executed first.
Here’s how it works:
You detect a large trade or transaction that is about to impact the price of an asset.
Using your access to unprocessed transactions, you create a transaction bundle that includes your frontrunning order.
You submit this bundle via Jito, which will ensure your transaction is included before the larger trade is processed.
As the larger transaction is confirmed, the price moves in your favor, and you make a profit.
By bundling transactions, frontrunners can effectively "squeeze in" their trade ahead of others, capturing the price movement and profiting from the trade.
Conclusion
Frontrunning on Solana is more complex and challenging than on Ethereum, mainly because the network does not offer a public mempool. However, savvy frontrunners are still able to capitalize on transaction submission flows by becoming RPC operators, trading bot operators, or even Solana validators themselves. Once they gain access to unprocessed transactions, they can use tools like Jito to bundle their trades and gain a first-mover advantage.
While frontrunning can be lucrative, it’s important to be mindful of the ethical and legal considerations. In DeFi, frontrunning is often seen as a form of market manipulation, and depending on how it’s executed, it could have consequences for your reputation or standing within the ecosystem.
For those interested in exploring frontrunning on Solana, it’s crucial to understand the infrastructure and technical requirements involved. Frontrunning is not for the faint-hearted, but with the right tools, knowledge, and access to transaction flows, it can still be a profitable venture.
