MEV Bot for Sale? What's Real, What's a Scam, and What It Should Cost

By Merunas Grincalaitis, founder of MEV DAO and a developer who builds MEV, sniping and trading bots on Ethereum. Last updated: October 2026.

TL;DR: You can't buy a ready-made, profitable MEV bot. A working MEV strategy stops being profitable once it's shared, so "profitable MEV bot for sale" offers are almost always scams. What you can legitimately pay for is a trading tool (Telegram sniper bots like Banana Gun and Maestro charge 0.5% to 1% per trade), free open-source frameworks you still have to build on, or custom development quoted by scope. If an offer asks you to fund a contract, hand over a private key or accept guaranteed returns, walk away.

Search mev bot for sale and you'll find a mix of Telegram bots, GitHub repos, "lifetime licenses" and sellers promising daily ETH profits. I build MEV, sniping and trading bots for a living, and a big part of my inbox is people asking whether something they found is real. This is the answer I give them: what's actually on offer, which offers are always scams, and what running a bot really costs.

Can you actually buy an MEV bot?

You can buy tools and developer time. You can't buy a profitable strategy off the shelf.

MEV (maximal extractable value) is the profit available from including, excluding or reordering transactions in a block: arbitrage between exchanges, liquidations on lending protocols, and so on. An MEV bot, or "searcher", finds those opportunities and competes to get its transactions included first.

That competition is the whole problem. ethereum.org's MEV documentation notes that for contested opportunities like DEX arbitrage, searchers may pay 90% or more of their MEV revenue in fees to the validator, and that well-known strategies like DEX arbitrage, liquidations and sandwiching "are unlikely to be profitable for new searchers." Even Flashbots' own simple-arbitrage example bot warns that it "is very unlikely to be profitable, as many users have access to it."

So when you see a bot for sale, the first question isn't "does it work?" It's "what exactly am I paying for?"

What's real and what's a scam?

Here's how I sort the offers I get asked about:

What's offered	What you actually get	Verdict
Telegram trading or sniper bot (e.g. Banana Gun, Maestro)	A hosted tool that executes your own trades, often through private transactions	Real tool, but it's a trading bot, not an MEV money machine
Open-source framework (e.g. Paradigm's Artemis, flashbots/simple-arbitrage)	Code you build your own strategy on	Real and free; profitable only if you add an edge
Custom development	A bot built to your spec, ideally with the source code	Real if the scope is clear and you own the code
"Deploy this contract in Remix and send it ETH"	A contract that forwards your ETH to the scammer	Scam, every time
"Deposit ETH and our MEV bot pays X% daily"	Nothing you control	Scam; fixed returns are the classic fraud signal
"Pre-configured" bot repo or package that needs your private key in a config file	Possibly malware that steals the key	High risk; never run unaudited
One-off "license" to a bot that's profitable today	Either an unprofitable bot or nothing	Almost always a scam

Why would anyone sell a profitable MEV bot?

They wouldn't, at least not for a one-time fee. From the inside, the reason is simple: an MEV strategy earns money because few people see the opportunity or can win it. Every buyer running the same logic bids for the same opportunity in the same block auction, and the extra bidding hands more of the profit to the block builder and validator. Selling copies of a working strategy destroys the thing being sold.

That leaves three kinds of sellers:

Tool businesses that charge for execution and convenience, not for a secret strategy. Banana Gun and Maestro both publish per-trade fees in their docs. That's an honest model.
Developers who sell their time to build your strategy, with the edge coming from you or from work that isn't shared.
Scammers, for whom your payment or deposit is the product.

What are the most common MEV bot scams?

I won't go deep on each here, but these are the ones I see most:

The YouTube "Remix contract". A tutorial has you deploy and fund a "bot" contract that sends your ETH to a hidden attacker address. SentinelLABS traced more than $900,000 to one version. I break down how it works in the YouTube MEV bot scam.
Managed bots with guaranteed returns. The CFTC's advisory on AI trading bots warns that promises of high or guaranteed returns are a fraud red flag, and cites Mirror Trading International, whose operator stole more than $1.7 billion in bitcoin from at least 23,000 people.
Malicious bot code. In 2026, GitHub's advisory database flagged npm packages posing as Polymarket trading tools that stole Ethereum private keys from users' .env files. The same trick works with any "ready-to-run" MEV bot repo.
Fake developers who ask for your seed phrase or for you to fund their contract before showing any code.

What does an MEV bot really cost to run?

The purchase price, if any, is the smallest part. The real costs are execution, infrastructure and the share of profit you give away to win blocks:

Cost	What it covers	What the sources say
Per-trade fees (hosted bots)	Using someone else's bot to execute	Banana Gun: 0.5% on manual buys and limit orders on Ethereum, 1% on autosniper. Maestro: 1% on every buy and sell
Your own node	Fast, reliable chain state for a custom bot	Reth's requirements for an Ethereum full node: at least 1.2TB of NVMe storage and 8GB+ of RAM (16GB recommended), stable 24Mbps+ connection (as of June 2025)
Gas and builder payments	Getting your transaction included ahead of competitors	ethereum.org: on competitive DEX arbitrage, searchers may pay 90%+ of MEV revenue
Development and maintenance	Building, testing and updating the bot as protocols change	Depends entirely on scope; there's no standard price
Trading capital	The funds the bot trades with	Set by your strategy; whatever you put in is at risk

What it should cost, then: a hosted tool should cost a transparent per-trade fee, open-source code costs nothing but your time, and custom work should be quoted after the developer understands your strategy. If you go the custom route, my guide on custom MEV bot development explains what a proper scope looks like. Anything priced as a one-off payment for guaranteed income is mispriced by definition.

How do you check an MEV bot before you pay?

Run through this list before any money moves:

Ask where the edge comes from. If the seller can't explain why their bot wins opportunities others can't, or claims it wins everything, assume it doesn't.
Never fund a contract you can't read. Ask for verified source code on Etherscan and check where every withdrawal goes.
Never share your main wallet's private key or seed phrase. If a bot needs a key, give it a fresh wallet holding only what you can afford to lose.
Check the seller. The CFTC suggests looking up the website's registration date at lookup.icann.org and researching the people behind it. A brand-new domain with anonymous founders is a bad sign.
Audit code and dependencies before running them. Read install scripts and dependencies, and run unfamiliar code in a sandbox, not on the machine holding your keys.
Test on a mainnet fork first. Simulating against real state costs nothing; see how to test an MEV bot on a mainnet fork with Anvil.
Start small and measure net profit. Count gas, builder tips, fees and failed attempts, not just gross wins.

Frequently asked questions

Is an MEV bot legit?

MEV bots are real software, and searchers run them on Ethereum every day. But a bot sold as guaranteed passive income, or one that asks you to fund a contract, is not legit.

Can I buy a profitable MEV bot?

Not as a ready-made product. Once a strategy is sold to many buyers they compete for the same opportunities, which is why even Flashbots says its public example bot is very unlikely to be profitable.

How much does a crypto bot cost?

Hosted trading bots typically charge per trade: Banana Gun charges 0.5% to 1% on Ethereum and Maestro charges 1%. Open-source frameworks are free, and custom development is priced by scope, plus your own gas and infrastructure.

Do crypto bots make money?

Some do, for operators with a real edge in speed, data or strategy. Copies of public strategies usually don't, because competition pushes most of the profit to validators.

Is it safe to download an MEV bot from GitHub?

Only if you can read and audit it. Malicious packages posing as trading bots have been caught stealing private keys from .env files, so never run one with a funded wallet before checking the code and its dependencies.
