How to Avoid MEV Bots on Solana: Practical Protection Steps

To avoid MEV bots on Solana, use tight slippage, trade in deep pools, split large orders, send through a wallet or router that offers protected transaction submission, and review your fills afterwards. These steps reduce the chance of being sandwiched, but no method removes the risk entirely.

Know what you are defending against

Most losses to MEV for ordinary traders come from sandwich attacks: a bot trades before and after your swap so you receive a worse price. We explain the mechanism in Solana sandwich attacks. Other forms, such as arbitrage, adjust prices after your trade but usually do not cost you directly. So the defence is mainly about making your trade a poor target.

A bot attacks when expected profit exceeds its costs. Your job is to shrink the profit available. Three things set it: your trade size relative to the pool, your slippage tolerance and how visible your transaction is.

The practical steps

Step	What to do	Why it helps	Trade-off
Tight slippage	Set the lowest tolerance that still fills	Limits how much price can be moved against you	Trade may fail in volatile markets
Deep pools	Prefer liquid pairs	Large pools are harder to move	Fewer options for new tokens
Split orders	Break big swaps into parts	Lowers profit per attack	More fees, more steps
Protected sending	Use wallets or routers that submit privately	Reduces visibility to attackers	Depends on provider and may change
Priority and tips	Attach a modest tip where offered	Can improve landing and protection	Costs a little; not a guarantee
Post-trade review	Inspect fills on an explorer	Spot patterns, adjust behaviour	After the fact only

Slippage in practice

Slippage tolerance is the maximum price move you accept. If you set 10 percent, you invite an attacker to push the price almost that far. If you set 0.5 percent, there is little room, but your trade may fail when the market moves, and you pay a fee for the failed attempt. Try a modest setting and adjust. For a very volatile new token, the right answer may be not to trade, or to trade very small.

Key takeaway: loose slippage is an open invitation. The setting you choose is the main lever you control.

Protected sending and tips

On Ethereum, private relays such as Flashbots Protect route transactions away from the public pool. Solana works differently, but some wallets and apps send transactions through Jito infrastructure and let you attach a tip, as described in the Jito documentation. Our bundle explainer gives the background. Read your wallet’s documentation to see what it actually does, because “MEV protection” is a label, not a guarantee. Fees themselves are explained in the Solana fee documentation.

Checking whether you were sandwiched

1. Open your transaction in a block explorer.
2. Look at the transactions in the same slot touching the same pool.
3. If an address trades just before and just after you, in the opposite direction, you may have been sandwiched.
4. Compare your received amount with the quoted amount.

Repeated patterns suggest changing your habits.

The other side: operators

Readers sometimes arrive here after reading about bots and wonder what the ethical bots do differently. Arbitrage and liquidation bots do not need to target your swap. Vendor sites such as CryptoMEV Bot’s Solana MEV bot page describe such strategies alongside others; that page, for instance, names DEX arbitrage and liquidations, and says its approach uses private, atomic Jito bundles. It does not discuss which of its strategies affect other users, so read product pages with that question in mind. The vendor’s front-run bot page is another example of a product that profits from user transactions.

What not to do

• Do not trust DMs offering “MEV protection” tools or asking for your seed phrase.
• Do not approve unlimited token spending to unknown programs.
• Do not use random “anti-bot” browser extensions without checking their source.
• Do not assume a high priority fee protects you from sandwiching.

A short routine

Before a larger swap: check pool depth, set tight slippage, split if needed, use a wallet with protected sending, and review the result. Then decide whether the cost of protection is worth it for the size of the trade. For a wider view of the risks around MEV, see Solana MEV bot risks.

Reading a transaction like an investigator

If you suspect you were sandwiched, a block explorer gives you most of what you need. Find your swap and note the slot. Then look at the other transactions that touched the same pool in that slot, in order. A sandwich leaves a recognisable shape: a buy of the token you were buying, then your swap, then a sell of the same token, usually by one address and often within a bundle. Compare the amount you received with the quote you were shown. The gap is your cost, and it is often small for a modest trade and meaningful for a large one.

Do not jump to conclusions from a single case. Prices move, other traders arrive in the same slot, and your own slippage setting may explain a worse fill. What you are looking for is repetition: the same trade pattern across several swaps, in thin pools, with loose settings. When you find it, the fix is usually behavioural rather than technical.

Matching protection to trade size

Trade type	Exposure	Sensible approach
Small swap in a deep, major pair	Low	Tight slippage, no special steps
Medium swap in a mid-liquidity pool	Moderate	Tight slippage, protected sending if your wallet offers it
Large swap in a thin pool	High	Split into parts, consider limit-style execution, or reconsider the trade
Newly launched token	Very high	Trade tiny or not at all; scams and bots concentrate here

Protection has costs, in fees, time and sometimes failed trades. For a few dollars, none of this is worth the effort. For thousands, a few extra minutes is cheap insurance.

Why some MEV is fine

It helps to separate harm from mechanism. When an arbitrage bot closes a price gap between two pools, your next trade probably gets a fairer price, and you never notice. Trying to avoid all MEV would mean avoiding the activity that keeps prices consistent. The target is narrower: avoid strategies that trade against your specific order. Operators who build cleaner bots tend to focus on arbitrage and liquidations for exactly this reason, and the vendor’s Solana MEV bot page lists those among its strategies, though it does not tell you how the software behaves toward your trades if you are on the other side.
