GMGN review

GMGN began as a site for tracking smart money and profitable wallets. It then added trading through the gmgn.ai web terminal, a mobile app and a set of Telegram bots. The bots cover Solana, BSC, Ethereum, Base and Tron. One GMGN account and one referral code work across the website and the bots.

DefiLlama files GMGN under the Telegram Bot category. That category name identifies the dataset. It does not show how much trading happens on the web terminal and how much happens on Telegram.

Custody: when you log in with Telegram or Phantom, GMGN creates new wallet addresses for you. GMGN's docs call the Phantom login a custodial wallet account. On all chains, GMGN does not let you export the private key, and this also applies to a wallet that you import. GMGN's safety guide says that GMGN cannot transfer the balance of a user's wallet. You can trade with your own browser wallet instead, but GMGN's Anti-MEV mode and automation tools do not work in that mode.

Withdrawals: the Telegram bots cannot send funds out. You withdraw on the website after you set up Google Authenticator and a whitelist of addresses. GMGN holds withdrawals for 3 hours after a new or changed whitelist and for 24 hours after you bind Google Authenticator again. GMGN also runs a bug bounty program that pays in USDT.

Incidents: on 26 October 2025, GMGN posted that a sandwich attack between 08:35 and 21:34 UTC on 25 October affected 729 transactions, and that it would pay back the losses in full without action from users. On 27 October, GMGN said rumors of a hack were false and that a security audit found no platform issue. On 28 October, Haze, who posts for GMGN.Ai on X, posted that an external phishing attack used fake third-party token sites to trigger unauthorized trades. He said about 107 users were affected and that GMGN would pay back 100% of those losses.

What we could not verify: we did not find the legal entity behind GMGN, a public third-party security audit, or proof of the repayments beyond GMGN's own posts. Phishing is the main risk that GMGN's safety guide names. GMGN staff never send the first private message and never ask for a private key. GMGN's token safety checks are for reference only. They do not make a memecoin safe to buy.

Platform fee: 1% of each transaction, with no other platform charges, per GMGN's fee docs. On a 1 SOL trade the fee is 0.01 SOL.

Network fee: gas goes to the network validators, not to GMGN.

Priority and tip fees: you set these to speed up a trade. They go to validators and private nodes, not to GMGN. The maximum is 2 SOL. Anti-MEV mode needs a priority fee of at least 0.002 SOL.

Launchpad fee: a token that still trades on its launchpad also pays that launchpad's own fee. GMGN's docs use Pump.fun as the example.

Token launch fee: GMGN's docs say that GMGN charges no fee to launch a token with its Cooking tool.

The MemeFees referral code for GMGN is COINTELLUS. GMGN's docs say that a referral link binds the code when a new user opens it, and that the same code works on the website and on the Telegram bots.

GMGN's public referral docs describe commissions paid to referrers. MemeFees separately supplies a platform trading-fee discount through COINTELLUS; the referral guide lists the current rate. The link-specific offer is not labelled as independently documented by GMGN. Check the applied rate before trading. Network, priority and tip fees are never discounted.

The core feature set carries over from GMGN's origins as a tracking tool: wallet monitoring, KOL (key opinion leader) wallet feeds, and smart-money signals sit alongside the trading functions. Sniping, copy trading, limit orders and take-profit or stop-loss orders are available from the web terminal or the Telegram bots, and a trade started in one interface uses the same wallet as the other.

Fees: GMGN, Axiom and Photon each list a 1% base fee. Axiom returns part of it as cashback, so its net fee falls from 0.95% to 0.75% as your trading volume grows. FOMO charges 0.50% per trade on most chains, with size-based tiers on Solana. The table below shows each terminal's fee terms from its own docs and the fees DefiLlama reports for the last 30 days.

Chains: Photon is a Solana app, and Axiom covers Solana, BSC and Robinhood Chain. GMGN covers Solana, Ethereum, Base and BSC. FOMO supports Solana, Base, BNB Chain, Ethereum, Monad and Robinhood Chain.

Referral terms: Axiom and FOMO publish a 10% discount for users who sign up with a referral code. GMGN and Photon do not document an invitee discount.

DefiLlama tracks fee-wallet inflows and deducts referral commissions to calculate retained revenue. Its current methodology measures Solana referral payouts on-chain and estimates EVM payouts using the measured Solana referral rate, described as roughly 16%. That estimate is not a fixed payout rate for every GMGN trade or chain.
