GMGN charges a flat 1% fee per transaction, and its docs list no cashback, volume tiers or referral discount, so a buy and a sell cost 2% of the position in GMGN fees. On top of that you pay priority fees and tips (GMGN suggests 0.002-0.005 SOL per normal trade), the launchpad or DEX fee, and a rent deposit for each new token.
Risk notice: Crypto trading is high risk and memecoins can go to zero in minutes. Trading bots and wallet connections use hot wallets. This page is not financial advice; only trade what you can afford to lose.
Facts on this page were checked October 23, 2026, from GMGN's own docs and the sources linked below. This is a research-based review built from published docs, not a hands-on trial. For features and track record, see our GMGN review; this page is only about cost.
GMGN's platform fee
GMGN's fee docs say: "GMGN only charges a 1% handling fee for a single transcation [sic], and there are no additional charges." Their example is a 0.01 SOL fee on a 1 SOL trade.
- Rate: 1% on every buy and every sell, on web, apps and the Telegram bot.
- Volume tiers: none documented.
- Cashback: none documented.
- Copy trades and limit orders: the same 1%; the docs give no separate GMGN fee for them.
That makes GMGN's fee simple to calculate: volume x 1%. On 10 SOL of monthly volume it's 0.1 SOL; on 500 SOL it's 5 SOL.
Does a GMGN referral code lower your fee?
Not based on GMGN's docs. The referral link page says referrers earn "a commission from the trading fees" of people they invite, and the referral program page says referrers can "Earn 10% to 30% in commissions". Neither page lists any discount, rebate or cashback for the invitee.
Third-party pages advertising GMGN invite codes with "15% off" or "20% off for life" aren't GMGN sources, and we could not match any of them to GMGN's docs. If GMGN ever shows a discount in the app, the app is the authority. Until then, plan on 1%. More detail: GMGN referral code.
Every other cost on a GMGN trade
GMGN's docs split on-chain costs into three parts, none of which GMGN keeps:
Gas. The Solana base fee, 5,000 lamports per signature (Solana docs). GMGN says no setting is needed.
Priority fee. Minimum 0.0001 SOL, paid to validators for faster confirmation.
Tip fee. Minimum 0.0001 SOL, paid to private nodes for faster processing. Jito, the main tip network, enforces a 1,000-lamport minimum per bundle (Jito docs).
GMGN's guidance on the total (priority + tip + gas):
| Use | Recommended total on-chain fee | Source |
|---|---|---|
| Normal trades | 0.002-0.005 SOL | GMGN |
| Automatic buy/sell limit orders | 0.006 SOL or more | GMGN |
| Anti-MEV mode | Priority fee of at least 0.002 SOL | GMGN |
| Maximum allowed | 2 SOL priority/tip | GMGN |
Launchpad and DEX fees. GMGN's fee page still says Pump.fun charges 1%, but Pump.fun's own fee page (updated October 17, 2026) lists 1.25% on the bonding curve and 1.25% down to 0.30% on PumpSwap. Use Pump.fun's figure. Raydium's standard AMM v4 pools charge 0.25% (Raydium).
Token account rent. Each new token needs a token account with a rent deposit, about 0.00149 SOL after Solana's 2026 rent cut versus 0.00204 SOL before it (Sol Incinerator). Refundable, but only when the account is closed.
Worked example: a 1 SOL round trip
Buy 1 SOL of a token and sell at the same price, with 0.003 SOL of on-chain fees per trade (mid-range of GMGN's 0.002-0.005 SOL suggestion). Our calculations:
| Cost | Pump.fun bonding curve | Raydium 0.25% pool |
|---|---|---|
| GMGN fee (1% x 2) | 0.020 SOL | 0.020 SOL |
| Venue fee (x 2) | 0.025 SOL | 0.005 SOL |
| Priority + tip + gas (x 2) | 0.006 SOL | 0.006 SOL |
| Total | 0.051 SOL (5.1%) | 0.031 SOL (3.1%) |
| Rent deposit (refundable) | ~0.0015 SOL | ~0.0015 SOL |
With anti-MEV on and a 0.002 SOL priority fee plus a tip, the per-trade figure can easily sit at the top of GMGN's range. At 0.005 SOL per trade, the curve round trip rises to about 0.055 SOL.
Worked example: 100 trades and limit orders
Take 100 trades of 0.5 SOL (50 buys, 50 sells, 50 tokens, 50 SOL of volume) in 0.25% pools:
| Cost | Manual trades (0.003 SOL each) | Limit orders (0.006 SOL each) |
|---|---|---|
| GMGN fee (1% of 50 SOL) | 0.500 SOL | 0.500 SOL |
| Venue fees | 0.125 SOL | 0.125 SOL |
| On-chain fees (100 trades) | 0.300 SOL | 0.600 SOL |
| Total | 0.925 SOL | 1.225 SOL |
| Rent locked (50 accounts) | ~0.074 SOL | ~0.074 SOL |
Automating with limit orders at GMGN's recommended 0.006 SOL doubles the network cost. On 0.5 SOL orders that's 1.2% per trade in fees to validators, more than GMGN's own 1%.
GMGN fees vs other Solana bots
| Platform | Base fee | Documented discount | Net for a new user | 100 x 0.5 SOL, platform fee only |
|---|---|---|---|---|
| GMGN | 1% | None | 1% | 0.50 SOL |
| Axiom | 1% | Cashback tiers + 10% referral | ~0.86% (referred) | ~0.43 SOL |
| Trojan | 1% | 20% cashback for all | ~0.8% | 0.40 SOL |
| Photon | 1% | None | 1% | 0.50 SOL |
| BONKbot | 1% | Telemetry cashback tiers | ~0.95% at Iron (see page) | ~0.48 SOL |
GMGN is tied for the most expensive platform fee among these bots. People choose it for copy trading and wallet tracking, not price. Full comparison: Solana trading bot fees compared and cheapest Solana trading bot.
Hidden-fee gotchas on GMGN
- Copy trading multiplies fees. Every copied buy and sell pays 1% plus on-chain fees, even when the copied wallet's trade fails to make money.
- Slippage defaults are wide. GMGN recommends 30%-35% slippage for automatic orders and 50% or more for new or hot tokens. That's a ceiling, not a fee, but on thin tokens it can cost more than every fee combined. See priority fees and slippage.
- Custom RPC doubles up. GMGN's docs say that with a custom RPC "both priority and tip fees will be charged at the same rate".
- The 2 SOL ceiling. Priority and tip can each be set as high as 2 SOL; a misplaced decimal is expensive.
- Rent may be stuck. GMGN's wallet docs say its wallets are "prohibited from exporting private keys". Without the key, outside tools can't close empty accounts, so that rent may stay locked.
How to lower your GMGN costs
- Don't pay for a "discount code". No invitee discount is documented; see GMGN referral code. If you want to sign up anyway, our link is Visit GMGN.
- Use the low end of the on-chain range (around 0.002 SOL) for trades that aren't time-critical.
- Prefer larger, fewer orders so fixed tips are a smaller share.
- Trade graduated tokens in low-fee pools when timing allows.
- Check rent before you pile up tokens. Read how to reclaim SOL from trading bots and best SOL reclaim tool.
