GMGN is a multi-chain meme-coin trading terminal (Solana, Ethereum, Base, BSC) with built-in wallet tracking and copy-trading. Here's how copy trading "smart money" wallets works there:
Step 1 — Find the smart money wallets to copy
Open GMGN → the Smart Money tab (or search smart money). It surfaces wallets that consistently profit on new launches, alongside top traders by PnL.
You can also click any wallet on a token's "holders" or "top traders" page to inspect its history — win rate, avg hold time, which tokens it caught early — before deciding to follow it.
The key screen is the wallet's portfolio page: shows its open positions, realized PnL, and recent buys/sells so you can see whether the wallet's style (early snipes vs. large-cap entries) matches what you want.
Step 2 — Set up the copy trade
From that wallet page, hit Copy Trade / Copy Wallet.
Configure your params:
Fixed amount vs. % of wallet for each order
Copy both buys and sells (or only buys) — mirroring sells matters, because copying only buys leaves you holding when smart money already exited
Max copy per token (so you don't overexpose on a single position)
Slippage and gas/priority fee
Toggle it on, and GMGN mirrors the wallet's trades automatically from then on.
Step 3 — Manage it
Watch the Copy Trading dashboard for active copy positions, total copied PnL, and stats per followed wallet.
Disable the copy at any time or set it to stop after a loss threshold.
The honest caveats (no tool makes this automatic profit):
Latency gap: you're copying a wallet's on-chain transactions, so you enter slightly after the smart money — on fast meme-coin launches that delay can be the difference between profit and rekt.
Copying only the "buys" is the classic mistake — their exit timing is half the edge, so mirror sells too.
Smart money wallets aren't static: a wallet's track record is historical; it can change behavior or even be a honeypot for retail copy-traders.
You still carry all the token risk — thin liquidity, no lock, rugged launches. Copy trading a wallet doesn't de-risk the asset itself.
GMGN's the full-featured web terminal for this; Maestro (Telegram bot) and Trojan are alternatives with the same copy-trading feature if you prefer a bot-style interface.
Not financial advice — if you try this, start small and set the per-token copy limits before anything else.
