The Flat 1%, and What It Leaves Out

What Does GMGN Charge?

One fee covers the entire product surface. GMGN's documentation says it "only charges a 1% handling fee for a single transaction, and there are no additional charges," with a worked example of a 1 SOL trade paying 0.01 SOL. That rate applies on the buy and again on the sell, so a round trip costs 2% of the amount traded. DefiLlama describes the same rate from the outside, measuring $240,126,547 in lifetime user-paid fees at 1% per trade when we queried its API on 6 August 2026. Terms can change, so confirm the live values in the app before you size a trade.

Cost Summary

• Any buy or sell: 1% of the transaction
• Sniper bot, copy trades, limit orders: the same 1%, no surcharge
• Launching a token through Cooking: 0 from GMGN, the launchpad still charges its own
• Priority fee and tip: you set them, 0.0001 to 2 SOL each, not collected by GMGN
• Subscription or pro tier: does not exist

How Does GMGN Compare to Other Terminals?

Nearly everyone in this category is quoted at exactly 1%, which makes headline fee close to useless as a way to choose. GMGN publishes a flat 1% in its own documentation, and Photon showed the same 1% in its own interface when we checked on 6 August 2026. Axiom is the documented exception: it starts at 1%, falls to 0.75% at its highest volume tier, and publishes a 10% fee discount for users who sign up through a referral link, so its published effective rate is lower than GMGN's. Trojan, Maestro and BONKbot are quoted at 1% across the web, but their fee terms sit behind a login or infrastructure that refuses automated requests, so we mark them unverified rather than copy a rate off a review site. The real differences are chain coverage and how much of the fee comes back. Over the 30 days to 2026-08-06, DefiLlama measured GMGN retaining 80.4% of the fees it collected and paying 19.6% out to referrers, against no measured referral outflow for Photon on the same window.

GMGN's and Axiom's rates are read from their own fee documentation; Photon's is read from its own interface. All three were checked on 2026-08-06. Trojan, Maestro and BONKbot are marked unverified because we could not reach primary documentation for them, and a rate copied from a review site is not a sourced rate. Rates change, so verify before trading.

What Do You Actually Pay on GMGN?

GMGN publishes its own formula for the chain-side cost: on-chain fee equals priority fee plus tip fee plus gas. None of that reaches GMGN, which states plainly that priority and tip fees are paid to speed up processing and are not collected by it. The practical consequence is that a mis-set priority fee cannot be refunded by anyone, because GMGN never had the money. GMGN's own Q&A records a user who sold a total of 0.12 SOL while paying a 0.2 SOL priority fee, then asked support where the SOL went. These are the fields to look at before you place anything, which is the last step of setup rather than the first: if you have not got that far yet, connect Telegram and fund your GMGN wallet first, then come back and set them.

Figures from the official GMGN fee documentation, read 2026-08-06. GMGN recommends a total on-chain fee of 0.002 to 0.005 SOL normally, 0.006 SOL or more for auto and limit orders.

Why Is Slippage the Real Cost?

GMGN recommends auto slippage for manual trades, 30 to 35% for automated buys, sells and limit orders, and 50% or more for new or hot tokens, per its official fee and settings documentation read 2026-08-06. Those numbers are not a fee, they are an authorization: setting 50% tells the router that a fill half a level below the quote is acceptable. On a thin pool that is what you get, and it dwarfs the 1%. GMGN's profit and loss display makes it harder to see, because the documented formula is realized plus unrealized profit with no fee term in it. A position that reads as flat has already cost you 2% in handling fees plus whatever the settings took, which is why reconciling against the transaction hash on a block explorer is worth the minute it takes. Sniping is where these settings bite hardest, because a new pair needs both a wide slippage tolerance and a priority fee high enough to land the block, and our trenches guide walks through how priority fees behave when sniping the Trenches.

The Referral Is Not a Discount

GMGN's referral program pays the referrer 10% to 30% of the fees GMGN collects, per GMGN's own referral documentation read 6 August 2026, with the rate negotiated rather than published as a tier table. No discount, rebate or bonus for the referred user appears anywhere in GMGN's documentation. Our link carries the code ggguide, which pays this site and changes nothing about your rate. Sites advertising 70% to 90% effective fees or an "80% cashback" are describing something that appears nowhere in GMGN's published terms, so if such an arrangement exists it is a private rebate between you and that site rather than a GMGN rate, and it is worth asking how it is paid before relying on it. As an independent check on the headline rate, DefiLlama measured referral outflows at 19.6% of fees over the trailing 30 days and 14.7% all time when we queried it on 6 August 2026, so the 30% ceiling is a rate almost nobody is on.

Real-World Cost Examples

• 1 SOL buy: 0.01 SOL handling fee, GMGN's own worked example
• 1 SOL round trip: 0.02 SOL in handling fees, before on-chain fees on both legs
• 0.1 SOL buy at GMGN's recommended 0.006 SOL on-chain fee: 0.001 SOL to GMGN plus 0.006 SOL to the chain, or 7% of the trade on the buy alone
• 0.05 SOL buy with Anti-MEV on: the 0.002 SOL priority-fee floor alone is 4% of the position

The four lines above are our own arithmetic, not GMGN figures. Every one of them multiplies out two documented inputs, the flat 1% handling fee and GMGN's recommended on-chain fee band, both read from the official GMGN fee documentation on 2026-08-06. The 1 SOL buy is the exception: that one is GMGN's own worked example, published on the same page.

The pattern is consistent: the smaller the trade, the less the 1% matters and the more the settings do. Fixed on-chain costs do not scale down with position size, so the same configuration that is sensible on a 5 SOL entry is punitive on a 0.05 SOL punt. To run the same arithmetic on your own trade size and settings, use the all-in trade cost calculator.
