This blog aims to explain how to start your own MEV from scratch in a more accessible way.

What is MEV (Maximum Extractable Value) Bot?

MEV Bot, also known as Miner Extractable Value Bots or Maximum Extractable Value Bots, is a software tool that is designed to monitor the blockchain networks (like Ethereum), especially in decentralized finance (DeFi).

These bots are used to find profitable opportunities and new transactions, enabling users to carry out transactions independently and smoothly. Eventually, these automated programs increase the profits by finding a new way within the blockchain transactions.

The MEV bots inspect the mempool and use sandwich, front-running, and arbitrage attacks to rearrange transactions into the block to maximize profits. In simple terms, the order flows in a blockchain are improved by creating the MEV trading bots. This platform operates within the decentralized finance (DeFi) ecosystem, utilizing blockchain techniques such as gas price bidding and transaction ordering.

MEV Bot Development

The MEV bot development plays a major role in the DeFi ecosystem. As the decentralized finance ecosystem continues to evolve, MEV bots play an important role and have become a key factor in leveraging advanced algorithms to reshape the market and unlock emerging opportunities. In essence, this brings out the maximum value from blockchain transactions.

According to the statistics, the MEV bot has an impressive profit of $1.4 billion since 2023. And it is predicted to reach more than 2 billion by the end of this year. Moreover, this reach has been achieved by some MEV bots, such as Flashbots (15%) and the Eden network (65%), in the global market.

How Does an MEV Bot Work?

The MEV bots function by scanning the mempool, and it involves a series of combinations of real-time data analysis, strategic acquisition positioning, and gas fee management. However, here is a step-by-step procedure for the working process of the MEV bot.

Observe the Mempool

A mempool serves as a temporary storage for saving remaining transactions. It actively tracks the transactions done in the mempool by having access to the mempool. They carefully analyze the transactions within multiple pools to find beneficial opportunities, ensuring they are identified before the transactions are confirmed on the blockchain.

Identify Profit Opportunities

Besides this, the bots conduct an in-depth evaluation of the pending transactions and identify the MEV opportunities using various strategies. These may primarily include gas fees, transaction types, and the processing time. Moreover, the bots examine the pending transactions in milliseconds, and they access several opportunities, including liquidation, arbitrage, huge trades, and other options.

Execute MEV Transaction

The next step is to execute the MEV transaction. This procedure is followed by recognizing the profit opportunities. Here, an MEV trading bot mainly focuses on programs such as backrunning, frontrunning, liquidations, flash loans, arbitrage, and sandwiching, each concentrating on enhancing profits.

Optimize Gas Price Bidding

The MEV bot often increases its gas fees to make sure the transactions are done on time without any delay. Moreover, this secures the transaction in the next block, preventing the opportunity from declining and ensuring faster processing.

Leveraging Special Platforms

Flashbots, a specialized platform, offers advanced tools to submit the MEV bot transactions to the miners or validators directly. The Flashbots platform offers features such as algorithmic trading, smart contracts, and transaction monitoring to increase the efficiency of transactions.

7 Main Types of MEV Bot Strategies

The bot comes in various types, and they undergo specific strategies to extract the maximum extractable value (MEV). Let’s delve into the section below to know the major types and strategies that are used to utilize the market's inabilities and transaction timings.

Arbitrage MEV Bot

An arbitrage bot, also known as an arbitrage trading bot, is automated trading software that is designed to automatically capitalize on prices for the same assets across multiple decentralized exchanges (DEXs) or markets.

For instance, the arbitrage bot plays a crucial role in the market by continuously buying at lower prices and selling at higher prices with a greater profit and minimal risk.

As a result, crypto arbitrage trading bot development has gained strong momentum, helping businesses and traders harness these opportunities efficiently.

This process of maximizing profits through arbitrage MEV in the financial ecosystem has made it quite popular.

Liquidation MEV Bot

A liquidation trading MEV bot is used to detect lending platforms for undercollateralized loans and is well-versed in utilizing liquidation opportunities in the decentralized finance protocols.

Here, the MEV bot operates continuously to grasp the collateralized positions and starts the liquidations when the collateral value drops below the defined threshold.

By generating these liquidation processes, bots can get profitable opportunities, especially in marketplaces where liquidation events are taking place frequently.

Frontrunning MEV Bot

Another type of MEV bot is the frontrunning bot, which capitalizes on placing transactions before others by gaining profit from its impact on the market price.

Typically, a frontrunning MEV bot is used in transactions and token launches, besides the need for high gas bidding.

However, these bots leverage price fluctuations and focus on high-value transactions, which results in significant profits.

Flash loan MEV Bot

A flash loan is a type of automated software that leverages MEV strategies and flash loans to utilize opportunities within the DeFi ecosystem.

These bots use flash loans, which are uncollateralized (borrowed loans), commonly used to pay back within the same transaction by minimizing the operation risk.

Using this loan, bots acquire large amounts of budget.

Gas Auction MEV Bot

In a gas auction, the MEV bot competes with other gas transactions by bidding higher gas fees, ensuring its transactions are prioritized and included in the next block before others.

This automated program is often used in flashbots, private mempools, and block builder markets with high, secure, profitable placement.

Sniper MEV Bot

The sniper bots are trading programs that are used to purchase the tokens from the blockchain platform automatically.

Using technical analysis and indicators, the sniper bot identifies optimal entry and snipes the valuable assets beforehand using smart contract interaction.

Sandwich MEV Bot

A sandwich MEV bot, also known as a sandwich attack bot, is well known for its layered approach, which operates on tokens by placing two transactions around a single target user’s trade.

The first transaction is called front-running, which creates a variable environment and profits the second transaction, called back-running. These two transactions combine to provide a lucrative opportunity.

Moreover, a sandwich MEV bot typically runs on a decentralized exchange (DEX) like Uniswap.

Below are some of the common sandwich bot strategies that you must consider while going through the MEV bot types.

Time Bandit Attack: Here, the attacker easily identifies and replaces the previously mined blocks that contain high-value MEV transactions. Henceforth, it is an enlightened version of the sandwich attack.

Liquidity Snipping: It refers to the monitoring of the blockchain mempool for liquidity and transactions when a new token is launched. Liquidity is directly provided to the decentralized exchanges (DEXs) in this context.

Pump and Dump Attack: This attack is known as a price manipulation strategy, which is often used on decentralized exchanges. Here, the orders are placed during price expansion, and the attackers gain maximum profit during market fluctuations.

Key Features of MEV Bot Development

Transaction Prioritizing

MEV bots prioritize transactions strategically and gain profit that corresponds with their selected MEV program. Once a profitable opportunity is found, MEV prioritizes and functions to include its own transaction in the block before others are added. This, in turn, is achieved by offering higher gas fees, ensuring they are included in the block, which potentially gains a head start in the market.

Mempool Tracking

The MEV bot continuously monitors and records the mempool, and the transactions are done within the blockchain network to find successful opportunities. It acts as a temporary storage to identify high-value transaction data before it is confirmed and acts preventively to perform programs like liquidation events, arbitrage, sandwiching, and frontrunning.

Liquidation Detection

The MEV bots can identify and monitor loan positions on lending protocols and thus automate the liquidation processes. This, in turn, quickly liquidates undercollateralized positions and allows traders to take a portion of the liquidated asset at a reasonable price.

Flash Loan Integration

By leveraging flash loans, known as temporary loans, the MEV bot plays complex arbitrage strategies to perform large trades quickly and efficiently. This feature lets traders capitalize on opportunities and suggests refunding the borrowed loans within the same block.

Gas Fee Optimization

The MEV bots ridiculously monitor and determine the gas prices by prioritizing their transactions. By adjusting the gas fee, the bots create a correct balance between profitability and unnecessary operational expenses and increase the overall profit margins.

Smart Contract Analysis

To perform complex strategies and to interact with the decentralized finance protocols directly, the bots often use the custom smart contract feature. However, the MEV bot accesses variables such as token swaps and liquidity pools within the smart contracts and thus focuses on identifying the vulnerabilities.

Dynamic Arbitrage Detection

The MEV bot helps to identify the price differences among different decentralized exchanges in an effective way. Moreover, the arbitrage trades are performed through flash loans to seize profits in a high-yield technique in real-time.
