GMGN review: fees, token screening and safety

GMGN is one of the most data-heavy memecoin terminals available. It pairs a trading interface (web, mobile app and Telegram bots) with on-chain analytics: who is buying a token, whether its contract can be abused, and which profitable wallets are moving. It charges a flat 1% per trade, blocks private key export from the wallets it creates, and works best for traders who research a token before buying. If you mainly want the cheapest execution, look elsewhere.

How much does GMGN charge?

The fees page is short: 1% per transaction, with no subscription and no other GMGN charge. A $500 buy costs $5 to GMGN and the matching sell costs about another $5.

On top of that you pay:

• Priority and tip fees. These go to Solana validators and private nodes. GMGN suggests 0.002–0.005 SOL per normal trade and 0.006 SOL or more for automated limit orders. Its FAQ describes a user who paid a 0.2 SOL priority fee to sell a 0.12 SOL position, so check this setting.
• Launchpad fees. Tokens still on a launchpad such as Pump.fun carry that platform’s own fee.
• Slippage. GMGN suggests 30–35% slippage for automated orders and 50% or more for brand-new tokens. That tolerance is a real cost when the market moves against you.

A referral link can trim the 1% (commonly to 0.9%). The GMGN referral code page has the numbers. For context, the 1% is on the high end among Solana terminals. The Axiom fee breakdown shows how a tiered model compares.

How to use GMGN to screen tokens

Most people use GMGN as a filter first and a trading tool second. Its data pages all ask the same question: is this token likely to be a trap?

Contract security checks

Every token page shows GMGN’s automatic checks. According to the CA security docs, on Solana these are:

• MintDisable: “Yes” means the creator can’t mint more supply.
• Top10 hold: “Yes” means the ten largest holders own less than 30% of supply.
• Blacklist: “No” means the contract can’t freeze your wallet. “Yes” means you may be unable to sell.
• Burnt: the share of the liquidity pool tokens that have been burned. 100% means the creator can’t pull liquidity.
• Rug probability and rug history: based on whether the holders tend to buy rugs, and on tokens the creator launched before.

On Ethereum and other EVM chains, the checks cover honeypot detection (via third-party data like GoPlus), verified source code, renounced ownership, locked or burned liquidity, and buy/sell tax. A sell tax near 99% means you can buy but not really sell.

GMGN’s own disclaimer says these checks aren’t 100% accurate. A contract can fake renouncement, and honeypot data can lag.

Insiders, snipers and the first 70 buyers

The holder breakdown tags insider wallets, snipers (wallets that bought in the first blocks) and the first 70 buyers, and shows how much of their position they still hold. It’s one of the most useful views on the platform. If snipers and insiders still hold a large share, they can sell into any rally you join.

Smart money, KOL wallets and alerts

On the Discover and Follow pages you can track wallets GMGN labels as smart money or KOLs. You get a notification when they trade and can import or export watchlists. Wallet Radar scans several tokens for shared holders, which helps expose a cluster of related wallets. X Tracker watches chosen accounts on X for new contract addresses.

GMGN’s own docs warn that smart money “also has a disorderly situation”. A wallet that looks smart can be one side of a coordinated pump.

A five-minute vetting routine

1. Open the token page and read the security row first. Walk away from mintable supply, an active blacklist, or a pool that isn’t burned.
2. Check Top10 and the insider/sniper tags. A concentrated supply means one exit can crash the price.
3. Look at the creator’s rug history.
4. See which tracked wallets hold it, and when they bought. Wallets that bought minutes before a KOL post are a warning sign, not a signal.
5. If you still want in, size the position as money you can lose completely, and set a stop or trailing take-profit before you buy.

Trading and automation features

GMGN’s automation goes deeper than most web terminals:

• Limit orders, take-profit and stop-loss, including trailing take-profit and trailing stop-loss.
• Auto-sell triggers such as “Dev Sell” (sell when the creator dumps part of their holding) and “Migrated Sell” (sell when the token leaves the launchpad for a DEX).
• Migrated Snipe to buy the moment a token graduates.
• Copy trading on Solana: up to 10 wallets, with filters for market cap, liquidity, token age, minimum burned-pool ratio and per-trade size caps. Every copied trade pays the 1% fee plus network fees, so copying a hyperactive wallet can drain your SOL fast.
• Lightning Mode for copy trading, which GMGN says is about 2 seconds faster. It acts on unconfirmed data, so it can occasionally buy a trade that never happened on-chain, or execute twice.
• Anti-MEV mode on Solana, with Off, Reduced and Secure settings, to cut the risk of being sandwiched.

The same wallets work across the web terminal and the Telegram bots (Solana, Ethereum, Base, BNB Chain and Tron have their own bots), so you can research on desktop and act from your phone.

Is GMGN safe?

The main risks, in order of how much they matter:

Custody and key export. When you first log in with Telegram, GMGN generates your trading wallets: one Solana address, one shared EVM address for Ethereum, Base and BNB Chain, and a Tron address. Per its wallet docs, exporting the private key is prohibited on all chains, even for wallets you imported. GMGN frames this as theft protection, and it does stop a common phishing route. It also means you can’t take the wallet elsewhere if GMGN goes down. Keep only trading money on it.

Withdrawal controls. Withdrawals can’t be made from the Telegram bot. They go through the GMGN site and need Google Authenticator plus a whitelisted address. There’s a 3-hour wait after you set or change the whitelist, and 24 hours after you re-bind 2FA. That’s a nuisance, but it protects you if someone takes over your Telegram account.

Phishing and fake bots. In October 2025, about 107 users were drained after signing transactions on a forged third-party token site. GMGN said it compensated them in full. The FAQ warns that admins never DM first and that fake GMGN bots and groups are common. Reach GMGN only through links from its official X account or docs.

The tokens themselves. This is the biggest risk. Most new memecoins go to near zero, and rugs, honeypots and coordinated dumps are routine. GMGN’s checks lower the odds of buying an obvious trap, but they don’t make memecoins safe.

Pros and cons

Pros	Cons
Deep on-chain data: insiders, snipers, first buyers, rug history	1% fee is high for frequent traders
Automatic contract checks on every token page	Private key export blocked on generated wallets
Solid automation: trailing stops, dev-sell and migration triggers	Copy trading limited to Solana
Web, app and Telegram share one wallet	Busy interface with a learning curve
Multi-chain, including Tron and BNB Chain	Frequent impersonation scams around the brand

Who should use GMGN, and who should skip it

Use it if you research tokens before buying, want to follow or copy specific wallets, or trade across Solana and EVM chains and want one tool for all of them.

Skip it if you trade very often and fee rates drive your results, if you insist on holding your own exportable keys, or if you want a simple app you can fund with a card. For the last case, Fomo is built around exactly that.

Verdict

GMGN is the research-first choice among memecoin terminals. Its holder breakdowns and contract checks are worth opening even if you trade elsewhere, and its automation covers most of what active traders want. The trade-offs are a flat 1% fee and wallets you can’t export. If that suits you, open GMGN and start with the screener before depositing anything.
