What Is GMGN? How the Memecoin Trading Terminal Works

GMGN is built for traders who chase new token launches. Its pages surface trending and newly launched tokens, show who is buying them and flag wallets it labels as insiders, snipers or early buyers ¹. A contract security check pulls data from third-party providers. GMGN says that data is for reference only and is not investment advice ¹.

Main features listed in the documentation ¹:

• Copy trading. You pick a wallet and GMGN mirrors its trades from your account. The docs call these "smart money" wallets.
• Automation. Auto buy, limit buy, auto sell, take-profit and stop-loss orders.
• Telegram bots. A Solana sniper bot, an Ethereum swap bot and an alert bot and channel ¹⁶.
• Referral program. Referrers get up to 30% of fees from the users they bring in ¹.

Memecoins are high-risk assets. Many new tokens lose most of their value within hours, and some are outright rug pulls. A security check flag lowers that risk; it does not remove it.

1. Log in. The docs recommend logging in through the @gmgnaibot Telegram bot, which sends a one-time login link ³⁵. You can also log in with a Phantom wallet, or reach GMGN from inside wallet apps such as Phantom, OKX Wallet, Trust Wallet, Bitget Wallet and TokenPocket ³⁵.
2. Fund the wallet. On first login GMGN creates a wallet address on each supported chain ³. You deposit by sending coins to that address. A deposit sent on the wrong network cannot be recovered ⁴.
3. Set fees and slippage. Before trading you set slippage and priority/tip fees (explained below) ².
4. Trade. Buys and sells go on-chain through decentralized exchanges or launchpads. GMGN shows charts and order tools on top ²⁷.

On Solana you can hold up to 10 wallets and buy or sell from several at once. Archiving a wallet closes its open orders and copy-trading settings ³.

GMGN charges a 1% handling fee per trade and says it adds no other charge. On a 1 SOL buy, the GMGN fee is 0.01 SOL ². Because both the buy and the sell are charged, a round trip costs about 2% in GMGN fees alone.

Other costs are paid to someone else ²:

Slippage is a hidden cost. The docs suggest settings of 30–35% for automated orders and 50% or more for new or busy tokens ². That means a trade can fill far from the quoted price. See slippage for how this works.

GMGN wallets are not self-custody wallets in the usual sense. The documentation says private keys cannot be exported on Solana, EVM chains or Tron. This also applies to wallets you imported ⁴. For Phantom logins, the docs describe the account GMGN creates as "custodial" ³. In practice, you rely on GMGN's systems to move funds out. (One section of the docs still points Telegram users to an export tutorial; the dedicated export page says export is blocked ³⁴.)

Withdrawal rules ⁴:

• Withdrawals work only on the website, not in the Telegram bot.
• You must bind Google Authenticator and set a whitelist of withdrawal addresses.
• After you first set or change the whitelist, withdrawals are locked for 3 hours.
• After you re-bind Google Authenticator, withdrawals are held for 24 hours.
• Each wallet keeps a small minimum balance, so "Max" does not send everything.

If you prefer to keep your own keys, see self-custody.

GMGN offers a data API with IP whitelisting, and trading APIs for Solana and for Ethereum, Base and BNB Chain ¹⁶. Access terms are set out in the docs rather than on a public price list. Wallet apps such as Phantom can open GMGN in their built-in browsers ⁵.

The documentation does not name a legal operator ¹. Co-founder Haze (@haze0x on X) has spoken for the company in public statements ⁸. Published reporting says GMGN started on Ethereum in 2023 and moved its focus to Solana in early 2024 ¹⁰. GMGN does not run identity checks in the trading flow described in its docs ³⁵.
