How to snipe on pump.fun and four.meme
To snipe on pump.fun, you buy a token in the first seconds after its pair appears, usually through a bot, before the chart has any history. The settings matter more than the tool: slippage, priority fee, MEV protection and an exit decided in advance. Expect 1% a trade on GMGN or Photon, charged again on the sell. A four.meme sniper on BSC works the same way.

How to snipe on pump.fun: what buying a new pair involves
A snipe is a market buy placed the moment liquidity appears, usually through a bot rather than a wallet interface.
How a launch plays out
- The launchLiquidity appears with no chart history, often no socials yet.
- The bot buysA market buy, plus a priority fee if the launch is contested.
- Fill or cancelIt fills inside your slippage cap and is cancelled past it.
- MigrationThe token leaves the launchpad, a second moment that counts.
What to snipe with
- New-pair snipers
GMGN, Photon, Banana Gun and Sigma document new-pair sniping, each with a published fee.
- Inside broader tools
Maestro, Trojan, Bloom, BONKbot, Axiom, o1.exchange and Based Bot document it among other features.
- pump.fun’s own Terminal
Formerly Padre, bought in October 2025. Its terms cap the fee at 1%, but no schedule or custody model is published, despite $3.58M in 30-day fees.
Step 1 — fix the settings before the launch, not during it
Slippage decides whether your order fills, and at what price. A wide cap protects the fill but gets expensive on larger orders; a tight one means more failed snipes. The risk changes shape, it doesn’t go away.
- Set a maximum slippage you can justify, and know the price you accept at that cap. GMGN’s docs recommend 30–50% on memecoins.
- Count the priority fee in your entry price: on a contested launch, it is what lands the order.
- Decide the exit before the entry: take-profit and stop-loss on GMGN, limit and DCA orders on Photon, auto-sell rules on Trojan.
Check on your tool
MEV protection. Smart-MEV on Photon, an explicit switch on Bloom; GMGN, Maestro, Trojan, Sigma and o1.exchange document their own.
Anti-rug. Banana Gun’s system tries to exit when a deployer pulls liquidity or changes taxes; Sigma pairs anti-rug tools with contract simulation.
Official domain and Telegram handle. Confirmed on the tool’s card before you fund the wallet you snipe from.
Step 2 — the Solana side: GMGN or Photon
Both charge a flat 1% and document new-pair sniping with MEV protection. GMGN does more, on more chains; Photon is the original Solana web sniper, with most of its usage behind it.
GMGN
Flat 1% per transaction
- $8.67M in 30-day fees on DefiLlama
- New-pair sniping, copy trading and anti-MEV
- Take-profit, stop-loss and trailing orders
- Solana and a long list of EVM chains, BSC included
Photon
Flat 1% on every buy and sell, in SOL
- $219K in 30-day fees, $442M since launch
- Limit orders, DCA and multi-wallet
- Smart-MEV protection
- Trading-wallet key exportable to Phantom
Step 3 — the BSC side: setting up a four.meme sniper
For a four.meme sniper, the settings stay the same; the chain changes, and so do the tools. Banana Gun, Sigma and o1.exchange document BSC coverage with sniper orders and published fees. GMGN covers BSC too.
What each charges on BSC
- Banana Gun
- 1%On snipes and on every chain but Ethereum, where manual trades pay 0.5%. One Telegram bot for every chain, and an anti-rug system.
- Sigma
- 1%Flat on every EVM chain, 0% on Solana. MEV and re-org protection, anti-rug, contract simulation. Not tracked by DefiLlama.
- o1.exchange
- 0.80%Net, after cashback, on a 1% headline fee; 0.60% at the top tier. 100% of its fees come from EVM chains, mostly Base and BSC.
Where sniping goes wrong
The most common failure is not a hack, it is arithmetic: a snipe that fills at a bad price, then pays a priority fee and two platform fees, must recover all three to break even.
- Latency
Your order lands after the ones already queued. Trojan documents nine backup bots; Sigma’s backup bots share your wallets and settings when the main one slows.
- MEV
GMGN users were sandwiched in October 2025 despite anti-MEV settings; GMGN compensated them. Anti-MEV is a setting, not a guarantee.
- The operator
Banana Gun’s bot compromise drained about $3M in September 2024; Maestro’s router exploit cost about $500K in October 2023. Users were refunded.
A prudent first snipe
Run your first snipes on one chain, with an amount small enough that a total loss is a cost of learning, and with the exit already programmed.
- Pick a tool with a published fee and a documented custody model, and read that field on its card first.
- Keep the sniping wallet small and separate from any wallet you use to hold positions.
- Cap the slippage, then check what happens to your order at that cap on a quiet launch before trying a contested one.
- Check the fee actually charged on your first fill against the one on the tool’s card.
- Platform fee on the buy
- 1%
- Platform fee on the sell
- 1%
- Total, before chain charges
- 2%
Gas, priority fee and slippage come on top. Write the full cost down before you start.
GMGN snipes on Solana and BSC for a flat 1%, with take-profit and stop-loss to program the exit.

Frequently asked questions
How much does it cost to snipe on pump.fun?
Three costs stack up. The platform fee is 1% per transaction on GMGN and Photon, 0.5% on Banana Gun’s manual Ethereum trades against 1% on snipes, and 1% on EVM for Sigma, which documents 0% on Solana trades. Gas, priority fees and slippage come on top, and a round trip pays the platform fee twice.
Which bot can snipe four.meme on BSC?
Our data documents BSC coverage for Banana Gun, Sigma and o1.exchange, all with new-pair or sniper orders and published fees. It does not document launchpad-specific behaviour for four.meme, so compare those three on fee, MEV protection and anti-rug tooling rather than on which one names the launchpad.
What slippage should I set on a new memecoin?
GMGN’s own documentation recommends 30–50% slippage on memecoins, which is a fill guarantee more than a setting. It gets expensive on bigger orders, and a tighter cap mostly produces failed snipes. Whatever you choose, decide it before the launch so that a live chart cannot change it for you.
Why do my snipes fail?
Usually latency or price impact. Your order arrives after the ones that were already queued, and a slippage cap protects you by cancelling rather than by filling badly. Tools acknowledge the problem by running backup bots: Trojan documents nine, and Sigma documents backup bots that share your wallets and settings when the main one slows down.
Is sniping on new pairs safe?
No. A new pair can be rugged by its deployer, and even published protections are described as attempts rather than guarantees: Banana Gun’s anti-rug system tries to exit when liquidity is pulled or taxes change, and Sigma’s anti-rug tooling sits next to contract simulation. Bad pricing, MEV and fees are additional risks on top.
Do I need MEV protection to snipe?
It is documented on most serious tools, and it is worth checking which kind. Photon documents Smart-MEV, GMGN, Maestro, Trojan, Sigma and o1.exchange document MEV protection, and Bloom documents an explicit switch. GMGN users were still hit by a sandwich attack in October 2025 despite anti-MEV, and were compensated, so treat it as a reduction rather than a removal.
