GMGN.ai: fees, wallet safety and how to use it
GMGN is a memecoin trading terminal with a website and Telegram bots. It charges 1% of every buy and every sell, with no subscription. Its strengths are wallet tracking and copy trading. The trade-off is custody: GMGN's own wallets do not let you export the private key, so withdrawals run through GMGN.
What GMGN is
GMGN is a terminal at gmgn.ai built around following "smart money" wallets. You can browse new and trending tokens, open a chart with holder and insider data, and buy from the same page. Telegram bots cover the same trading functions inside chat, with separate bots for Solana, Ethereum, Base, BNB Chain and Tron.
There are two ways to trade. You can connect a browser wallet such as Phantom and sign each trade yourself. Or you can log in with Telegram, which creates a GMGN wallet that the platform operates for you. Copy trading needs the Telegram login, according to GMGN's documentation, and GMGN recommends it for its automated orders.
Every token page shows quick safety checks, for example whether minting is disabled, how much the top ten holders own and how much of the liquidity is burned. GMGN labels these checks as reference only.
GMGN fees
GMGN's fee page states a 1% handling fee on each transaction and no other GMGN charges. A $1,000 buy costs $10 and the later $1,000 sell costs another $10. There are no volume tiers and no cashback in the documentation.
The same page lists the costs that are not GMGN's:
| Cost | Who gets it | What GMGN's documentation says |
|---|---|---|
| GMGN fee | GMGN | 1% of each transaction. Nothing to set. |
| Priority fee and tip | Validators and private nodes | Minimum 0.0001 SOL each. A total of 0.002 to 0.005 SOL is usually enough for trades that are not urgent, and 0.006 SOL or more is suggested for automatic orders. |
| Anti-MEV mode | Private nodes | Optional protection against sandwich attacks. Needs a priority fee of at least 0.002 SOL. |
| Launchpad fee | The token's launch platform | Charged by the launchpad, not GMGN. On a Pump.fun bonding curve it is currently 1.25% per trade. |
| Slippage | The market | A limit you set, not a fee. GMGN suggests 30% to 35% for automatic orders on volatile tokens, which is a wide margin. |
Referral links and discounts
GMGN's documentation describes what the referrer earns, 10% to 30% of the trading fee depending on volume, and does not publish a fixed discount for the invited user. Third-party pages quote anything from 10% to 30% off. Treat those numbers as claims until you see the rate on your own account. The fee calculator on solmath assumes 10% off for a referral sign-up, which gives 0.90% per side.
Copy trading costs add up
Each copied trade pays the trade amount, the priority fee and the 1% fee. GMGN's own documentation warns that many users who copy a busy wallet end up losing money to priority fees even when the trades themselves are profitable. Copy trading works on Solana only and is limited to ten copy tasks.
Is GMGN safe?
GMGN is an established platform with a public bug bounty program and a record of repaying users after incidents. The main thing to understand is who controls the keys.
- GMGN wallets are not exportable. The documentation says private keys cannot be exported on any chain, and that also applies to a wallet you import. You depend on GMGN to move funds out. If you want full control, trade with a connected browser wallet instead and accept that copy trading is not available that way.
- Withdrawals have deliberate delays. You bind Google Authenticator and add a withdrawal address to a whitelist. No withdrawals are allowed for 3 hours after the first whitelist setup or any whitelist change, and for 24 hours after re-binding the authenticator. The bot cannot withdraw, so withdrawals happen on the website. Each wallet also has to keep a small minimum balance, which means "Max" does not send everything.
- Past incidents. On 25 October 2025 an MEV attack affected 729 transactions, and co-founder Haze said two days later that the affected users had been compensated. In the same week GMGN reported a phishing attack that affected about 107 users and said it would cover the losses in full.
- Impersonators. GMGN's documentation repeats that its admins never message you first. Fake admins and cloned bots are the usual way accounts are lost.
- Safety checks are hints. A token that passes every check can still go to zero. GMGN says the checks are for reference and cannot be fully accurate.
How to start on GMGN
- Open GMGN from a link you trustUse the official site, gmgn.ai, or a referral link that points to it. Check the address bar before you log in.
- Pick how you will tradeConnect Phantom to sign trades yourself, or log in with Telegram to get a GMGN wallet with copy trading and automatic orders.
- Set up withdrawal security before depositingBind Google Authenticator and whitelist your own wallet address. Remember the 3-hour wait after the first setup.
- Deposit a small amount of SOLSend only what you plan to trade, and add more once a withdrawal has worked.
- Choose slippage, priority fee and Anti-MEVLow priority fees are fine for slow trades. Fast entries on new tokens need more, and that cost is charged on every transaction.
- Make one small trade and read the resultOpen the transaction hash and check the GMGN fee, the priority fee and the tokens received.
Who GMGN suits
Good fit
- You want to follow or copy specific wallets and get alerts in Telegram.
- You trade on more than one chain and want one interface.
- You use the holder, insider and sniper data to screen tokens before buying.
Less of a fit
- You want a wallet whose key you can export and take elsewhere.
- You trade enough volume to benefit from cashback tiers, which GMGN's documentation does not offer.
- You need instant withdrawals right after changing security settings.
Questions

1% of every buy and every sell. There is no subscription and GMGN's documentation lists no other platform charges. Priority fees, tips and launchpad fees are separate.
Is there a GMGN referral discount?
GMGN's documentation publishes the referrer's rebate, 10% to 30%, and no fixed discount for the invited user. Any discount is tied to the invite link, so confirm the rate on your account after signing up.
Can I export my GMGN wallet's private key?
No. GMGN's documentation says private keys cannot be exported on any chain, including wallets you imported. Funds leave through a withdrawal to a whitelisted address.
Why can't I withdraw from GMGN yet?
Withdrawals are blocked for 3 hours after you first set up or change the withdrawal whitelist, and for 24 hours after re-binding Google Authenticator.
Does GMGN copy trading work on Ethereum or Base?
GMGN's documentation says wallet copy trading is supported on Solana only, with up to ten copy tasks per account.
