📋 How we built this settings guide: Pulled from the official GMGN documentation and the GMGN web terminal interface, cross-checked against Solana Trading Bots reporting and active testing on Pump.fun launches through May 2026. Settings reflect GMGN’s current execution settings (Off / Reduced / Secure MEV protection modes), Turbo and Anti-MEV slippage tiers, and Smart Money copy trading framework. Last verified May 15, 2026.
GMGN is the on-chain trading platform best known for its AI-powered smart-money tracking and copy trading on Solana — with a web terminal at gmgn.ai for discovery and a Telegram bot at @GMGN_sol_bot for execution. Default settings work for casual trading; optimized settings across slippage, priority fee, MEV protection mode, and copy-wallet filters produce meaningfully better outcomes. Here are the GMGN settings that matter most and the values that calibrate well to current Solana conditions.
If you’re still picking a bot, the BonkBot review and Banana Gun review cover the broader trade-offs in the category.
⚡ TL;DR — Best GMGN Bot Settings
- Slippage (Pump.fun launches): 10–15% standard; 15–20% on hot launches; 5–8% established tokens
- Priority fee (Jito tip): 0.01–0.03 SOL standard; 0.05–0.1 SOL competitive launches
- MEV protection mode: Secure (default for new launches); Reduced (faster, moderate protection); Off (lowest latency, MEV exposed)
- Position size: 0.1–0.5 SOL per trade, max 2–5% of trading wallet
- Copy trading: 5–7 AI-filtered wallets, 10–20% mirror size, >60% win rate over 30+ trades, >7-day history
- Stop-loss: -30% to -40%
- Take-profit (auto-sell): 2X conservative / 5X aggressive
- Anti-MEV Slippage mode: ON when MEV protection is Secure; otherwise routine slippage controls suffice
- Platform fee: 1% per trade — no volume cashback (compare to Trojan Arena’s up to 45% rebate)

Setting-by-setting breakdown
Slippage — and the GMGN slippage modes
GMGN exposes three slippage behaviors:
- Auto Slippage — GMGN dynamically calibrates based on token liquidity and volatility. Good for unfamiliar tokens; you trade explicit control for adaptive defaults.
- Turbo Slippage — Higher tolerance for fast swaps in volatile markets. Use during competitive Pump.fun launches.
- Anti-MEV Slippage — Lower tolerance to protect against sandwich attacks; may slow transactions. Pair with Secure MEV protection mode.
Base values: 10–15% on new Pump.fun launches, 5–8% on established tokens, 1–3% on stable swaps. Push to 15–20% on hot launches where the failure cost of a missed entry is bigger than the cost of overpaying. Above 25%, you’re executing at any price.
MEV protection — Off / Reduced / Secure
GMGN’s MEV protection is a three-mode dial, not on/off:
- Off — Transactions sent to all nodes. Fastest, but fully exposed to sandwich attacks. Use only for stable swaps or tokens with extremely thin MEV opportunity.
- Reduced — Transactions sent to a limited set of nodes. Faster than Secure, but not fully MEV-proof. Reasonable middle ground for routine trades.
- Secure — Transactions routed through Jito’s private mempool. Maximum protection but higher latency. Use this for competitive launches and large-size trades.
Practical default: Secure for new launches and any trade above 0.5 SOL. Reduced for routine 0.1 SOL trades on established tokens.
Priority fee (Jito tip) — match to congestion
0.01–0.03 SOL standard, 0.05–0.1 SOL for competitive launches. The tip incentivizes Solana validators to include your transaction in the next block. During congestion, low tips mean slow or failed transactions. Never set the tip to 0 on competitive trades. Never set the tip larger than your trade size (a 0.05 SOL trade with a 0.05 SOL tip is an automatic 50% loss before execution).
Position sizing — the single most important risk control
0.1–0.5 SOL per trade is the standard band, and no single position should exceed 2–5% of your trading wallet. This is the lesson every active trader eventually learns — the bot doesn’t protect you from the catastrophic loss of putting half your wallet into one launch that rugs. GMGN’s execution speed only matters if you’re still in the game next week.
Copy trading — GMGN’s differentiator
Smart Money Copying is what GMGN does best. The platform’s wallet tracking and AI-powered filtering tools surface high-performing wallets for replication. The settings that matter:
- Follow 5–7 wallets max. More than that and signal degrades into noise.
- Filter by win rate above 60% over 30+ trades. The 30-trade minimum filters out single-month lucky streaks. The 60%+ threshold rules out gambling-pattern wallets.
- Minimum 7-day history — short-history wallets are statistical noise.
- Profitable across 1-day / 7-day / 30-day windows — consistency, not single-day moonshots.
- Mirror size at 10–20% of source wallet’s position — proportional sizing preserves the signal of the source wallet’s sizing decisions.
Important caveat: GMGN’s execution speed for copy trading has been documented as slower than pure-snipe bots like Banana Gun. For copy trading specifically, the speed is acceptable; for first-block sniping where copy-trading isn’t the use case, faster bots fit better.
Stop-loss and take-profit — automated server-side
GMGN’s auto-sell rules execute server-side, so they trigger even when Telegram is closed. Stop-loss at -30% to -40% as standard floor, take-profit at 2X conservative or 5X aggressive. Set both before you enter the position — once you’re in the trade, your judgment is compromised by P&L emotion. Scaled TPs (sell 50% at 2X, 30% at 5X, ride the remaining 20%) work well on memecoins where the long-tail distribution rewards letting winners ride.
GMGN web terminal vs Telegram — when to use which
| Use case | Best surface | Why |
|---|---|---|
| Wallet discovery / smart money scanning | Web terminal (gmgn.ai) | Multi-tab dashboard, advanced filters, full analytics |
| Fast snipe on a live launch | Telegram bot | One-tap preset execution, fastest from notification to fill |
| Setting up copy trading | Web terminal | Smart Money filters easier to configure with full data |
| Monitoring open positions | Web terminal | Multi-tab portfolio view |
| Early-buyer / pump FOMO alerts | Telegram bot | Real-time push notifications |
| Custom limit orders + DCA | Either | Both surfaces have full server-side execution |
The two surfaces don’t always sync flawlessly — some users report watchlist desync between Telegram and web. If you rely on watchlists, configure them in the surface where you’ll actually trade from.
💡 Expert tip — GMGN’s biggest leverage point isn’t a setting: The most important GMGN decision isn’t slippage or priority fee — it’s wallet selection for copy trading. A wallet that hits 60% win rate over 30+ trades and is profitable across all three time windows (1d/7d/30d) is genuinely rare; if you find 5–7 of them, you’ve compounded your edge dramatically. Spend more time on the Smart Money filters than on tweaking slippage — that’s where GMGN’s value sits versus simpler bots.
Settings to avoid
- Slippage above 25% routinely. Acceptable on a single hot snipe; not acceptable as a default.
- MEV protection Off on large trades. Sandwich attacks scale with trade size — a 5 SOL position is a juicy target without protection.
- Copy trading 10+ wallets simultaneously. Signal collapses into noise; you end up mirroring contradictory positions.
- Fixed-SOL copy mirror size. You lose the source wallet’s proportional sizing signal entirely. Always use percentage-of-source.
- Stop-loss below -50%. You’re hoping for a bounce that rarely comes on meme coins.
- Trading from your main wallet. Dedicated trading wallet, always.
