Settings and execution
Axiom MEV protection: the three modes explained
MEV protection on Axiom decides whether bots can see your buy before it confirms. Axiom offers three modes: Off, Reduced and Secure. Secure routes your transaction only through Jito and waits for a whitelisted validator, which Axiom recommends "whenever possible". This guide explains the attack it prevents, what each mode does, and the trade-off between protection and speed.
What MEV is
MEV stands for maximal extractable value: profit that validators or bots take by reordering transactions. On a memecoin buy, the common form is a sandwich. A bot sees your buy waiting in the public queue, buys the token just before you so the price rises, lets your order execute at that higher price, then sells straight after. You get fewer tokens; the bot keeps the difference. Axiom's docs describe this as forcing you "into an instant loss", and the larger your slippage allowance, the more a bot can take.
The three modes
| Mode | Routing | Protection | Speed |
|---|---|---|---|
| Off | Broadcast to Jito and standard block leaders | None; trades are exposed to front-running | Fastest |
| Reduced | Submitted via Jito | Partial; rogue validators may still see the transaction | Fast |
| Secure | Via Jito, waiting for a whitelisted validator | Axiom's strongest protection | May be slower while it waits |
Axiom's documentation is direct about the recommendation: use Secure whenever possible. It also notes that protection matters for buys and is generally unnecessary for sells.
How the bribe fits in
MEV protection on Axiom is paid for through the bribe, the tip attached to your transaction for block builders. The hand-and-coin icon at the top right of the terminal shows the current minimum MEV bribe; Axiom says your bribe should be set higher than that minimum to stay protected. Axiom also calculates a recommended bribe from live conditions. A higher bribe increases the chance the protected route is used, though Axiom's docs are explicit that it is not 100% effective.
When traders turn it down
On the most competitive launches, the delay while Secure waits for a whitelisted validator can mean missing the entry entirely. Some traders drop to Reduced, or even Off, for those seconds. If you do, Axiom's own advice applies: keep slippage low so there is less for a sandwich bot to take, and accept that a worse fill is the price of speed. Put the mode back to Secure afterwards.
What MEV protection does not do
- It does not stop price impact. A large buy into a thin pool moves the price with or without bots.
- It does not stop a rug pull or a bundled launch. Those are token risks; see the bundle checker.
- It does not guarantee inclusion. A congested network still needs an adequate priority fee.
- It does not cost a separate Axiom fee. Axiom lists no charge for the feature beyond the bribe that goes to the network.
Checking whether you were sandwiched
Open your transaction on Solscan and look at the transactions immediately before and after it in the same block. A matching buy before and sell after your trade, from the same wallet, is the signature. If you see it regularly with Secure mode on, raise the bribe above the minimum Axiom shows.
MEV FAQ
Should I always use Secure mode?
For buys, yes, unless you consciously trade protection for speed on a competitive launch. For sells, Axiom's docs say protection is usually unnecessary.
Does MEV protection make trades slower?
Secure mode can, because it waits for a whitelisted validator. Axiom describes the delay as slight.
Is Jito the same as MEV protection?
Jito is the infrastructure Axiom routes protected transactions through. The protection comes from keeping your transaction out of the public queue until a trusted validator includes it.
Why did I still get a bad price with protection on?
Most likely price impact on a thin pool or a wide slippage allowance being consumed by normal volatility. Check Solscan for an actual sandwich before blaming the mode.
