How to Use Banana Gun on Ethereum vs Flat-Fee Sniping

By Merunas Grincalaitis (X · GitHub · DEV · Hashnode · Telegram), Founder & Lead MEV Engineer at MEV DAO — Ethereum smart contract, Flashbots & MEV builder since 2017. Last updated: October 2026.

TL;DR: Learning how to use banana gun on Ethereum takes about five minutes inside Telegram or the Banana Gun Pro web app, where you generate or import a burner wallet, paste a token contract address, and set an ETH auto-snipe tip. However, when traders ask is banana gun free, the real answer is no: Banana Gun charges 1.0% on every Ethereum auto-snipe and 0.5% on manual swaps (around 1.5%–2.0% per round trip) while holding your trading keys in a custodial setup. If you snipe with 0.5+ ETH on Ethereum mainnet, switching to a non-custodial flat-fee setup like MEV DAO saves hundreds or thousands of dollars per month.

This guide focuses specifically on how to use banana gun with production Ethereum mainnet parameters and runnable verification steps.

Whether you are brand new to Ethereum token launches and searching what is a crypto sniper and how to use telegram bots, or you are an active trader looking up how to use banana gun sniper bot without losing your bankroll to honeypots and builder wars, you need to understand both the mechanics and the hidden fee math behind Telegram routers.

Below is the complete, step-by-step walkthrough of what is banana gun bot, how does banana gun work on Ethereum block-0 launches, how to configure safe gas and slippage settings, and the exact trade volume threshold where a flat-fee Flashbots sniper and vetted Telegram group beats paying 1% on every single snipe.

What is Banana Gun Bot, and how does Banana Gun work on Ethereum?

First, what is banana gun bot (banana gun crypto)? Originally launched in 2023 as a telegram sniper bot and expanded with the web-based Banana Gun Pro terminal, Banana Gun is a custodial trading router that lets retail users place manual swaps, limit orders, and automated block-0 token launch snipes on Ethereum, Solana, Base, and Sonic.

When you ask how does banana gun work under the hood during an Ethereum Uniswap token launch, here is what happens behind the Telegram buttons:

Pooled bundle routing: Suppose 40 different Banana Gun users all paste the same upcoming ERC-20 contract address (0xToken...) and queue an auto-snipe before the developer enables trading.
Internal bribe auction: When the developer broadcasts enableTrading() or addLiquidityETH to the Ethereum mempool, Banana Gun's backend orders its own users by who offered the highest extra ETH miner/builder tip (snipe bribe), packages their swaps through the public Banana Gun Router contract (0x3328F7f4A1D1C57c35df56Bf50c9dCafCA309C49), and submits a private bundle to Ethereum block builders.
Router fee deduction: On every successful transaction, the Banana Gun router automatically skims 1.0% of your trade volume on auto-snipes (or 0.5% on manual buys/sells) before delivering the tokens or ETH to your wallet.

How does this compare to maestro bot (maestro bot crypto) or a dedicated non-custodial Flashbots bot? Notice two structural trade-offs of pooled Telegram routers:

First, you are bidding against other Banana Gun users inside the same router bundle, and if 15 users are packaged into one giant bundle that hits a contract's global gas limit or triggers an anti-router blacklist (require(msg.sender != bananaRouter)), the bundle can fail or get outbid by a leaner single-wallet searcher bundle.
Second, every copy-trading bot on Ethereum watches the Banana Gun and Maestro router addresses 24/7. The moment your wallet swaps through a public telegram sniper tool router, wallet-tracking bots tag your address.

Step-by-step: How to get Banana Gun and set up an Ethereum snipe safely

If you are trading small positions (0.05 to 0.2 ETH) and want to know how to get banana gun and how to use banana gun safely without exposing your main portfolio, follow these five mandatory security and configuration steps:

Step 1: Verify the official bot handle (avoid clone phishing bots)

Never search for banana gun or banana gun code inside Telegram's global search bar—scammers create dozens of verified-looking clone bots with slightly misspelled usernames that immediately steal any ETH you deposit. Always launch the registration bot and sniper bot links directly from the official documentation at bananagun.io (or use the official web terminal).

Step 2: Generate an isolated burner wallet (NEVER import your main seed phrase)

Because Banana Gun is a custodial telegram sniper bot (your private key passes through or is encrypted on their backend infrastructure, which suffered a high-profile $3M wallet-drain incident in September 2024 before being patched), never import your main MetaMask, Rabby, or Ledger wallet.

Generate a fresh burner wallet inside the bot.
Export the burner private key into a local wallet like Rabby so you have an emergency backup way to interact with tokens if Telegram goes down.
Fund the burner wallet with only the exact ETH you plan to trade in that session (e.g., 0.25 ETH), and sweep profits back to a cold hardware wallet at the end of every day. (Read our full security audit in Are Telegram Trading Bots Safe? Key Custody & Hacks.)

Step 3: Configure Auto-Snipe parameters (`how to use banana gun sniper bot`)

When you paste an upcoming Ethereum token contract address into the Sniper menu, you must configure five critical parameters before the developer opens trading:

Snipe Amount (ETH): The maximum ETH you are willing to spend to buy the token (if the token has a maxWallet cap of 1% of supply and 1% only costs 0.08 ETH, the router will buy the 0.08 ETH cap and refund excess ETH).
Auto Snipe Miner Tip (Bribe): The extra ETH paid to the block builder (block.coinbase) to win inclusion in Block 0. On quiet launches, 0.015–0.03 ETH is common; on hyped launches, bribes exceed 0.10 ETH.
Max Buy Tax / Max Sell Tax: Set hard ceilings (for example, 15% buy tax and 15% sell tax) so the bot aborts if the developer launches with a 50% predatory tax.
First Bundle or Fail (FoF): If enabled, your snipe only executes if Banana Gun's bundle wins the very first slot in the launch block. Keep First Bundle or Fail ON for high-bribe snipes so you do not accidentally pay a 0.1 ETH bribe to buy at the top of Block 0 after 30 other wallets already pumped the price 10x!
Slippage: For Manual Buys, set slippage (5%–15% on volatile launches) and always keep Anti-MEV / Private Routing ON.

Is Banana Gun free? The real 2026 fee math vs. flat-fee sniping

Many newcomers ask is banana gun free because there is no upfront monthly credit card screen when you open the Telegram chat.

In reality, a 1% auto-snipe fee + 0.5% manual sell fee is the most expensive way to trade on Ethereum once you move past tiny beginner size. Let's look at the exact fee table across a month of active Ethereum sniping:

Monthly Trading Volume (20 Round-Trip Snipes)	Banana Gun Fees (`1.0%` Snipe + `0.5%` Sell)	Maestro Bot Fees (`1.0%` Buy + `1.0%` Sell)	MEV DAO Sniper Bot & Group (Flat Fee, `0%` Per Trade)
0.1 ETH per trade (`2 ETH` total volume)	~~`0.03 ETH` (~~$75/mo)	`0.04 ETH` (~$100/mo)	Flat subscription (3-day free trial)
0.5 ETH per trade (`10 ETH` total volume)	~~`0.15 ETH` (~~$375/mo)	`0.20 ETH` (~$500/mo)	$0 per-trade tax (keep 100% of volume)
1.5 ETH per trade (`30 ETH` total volume)	~~`0.45 ETH` (~~$1,125/mo)	`0.60 ETH` (~$1,500/mo)	$0 per-trade tax (save >$1,000/mo)
3.0 ETH per trade (`60 ETH` total volume)	~~`0.90 ETH` (~~$2,250/mo)	`1.20 ETH` (~$3,000/mo)	$0 per-trade tax (save >$2,000/mo)

(Note: Using a banana gun code referral link only shaves a tiny fraction off the fee while still charging percentage volume tax on every single buy and sell.)

Why a tool alone isn't enough: Pairing flat-fee execution with a sniping group

Knowing how to use banana gun (or any sniper bot) solves only half the problem. If you point an automated sniper at random contract addresses posted on public X threads, 9 out of 10 launches you snipe will be soft rugs, delayed honeypots, or developer farm dumps.

That is why experienced Ethereum traders move away from isolated 1%-fee retail bots and into the MEV DAO Premium Sniping Group on Telegram paired with our non-custodial Ethereum Sniper Bot:

0% per-trade router fees: You never pay 1% on entry or exit, and your trades don't pass through a flagged public retail router that anti-snipe contracts specifically blacklist.
Pre-launch contract & deployer vetting: Before liquidity drops, we inspect bytecode for hidden deadblocks, blacklist hooks, and serial rugger funding wallets.
Full key self-custody: Your private keys stay under your control rather than sitting in a centralized Telegram bot database.

Frequently asked questions

What is Banana Gun Bot in crypto?

Banana Gun Bot is a custodial Telegram trading bot and web terminal (Banana Gun Pro) that allows users to auto-snipe new token launches, execute manual DEX swaps with anti-MEV routing, and place limit or copy-trade orders on Ethereum, Solana, and Base.

Is Banana Gun free to use on Ethereum?

Opening the bot in Telegram has no upfront subscription cost, but Banana Gun is not free: it deducts a 1.0% fee on every Ethereum auto-snipe (plus your block builder bribe) and a 0.5% fee on manual buys, sells, and limit orders. For active traders sniping 0.5 ETH or more per launch, those percentage fees add up to hundreds or thousands of dollars per month.

How does Banana Gun work on block-0 token launches?

When multiple users queue an auto-snipe for an unreleased Ethereum token, Banana Gun monitors the mempool for the developer's addLiquidity or enableTrading transaction, bundles its users' buy orders through the Banana Gun router sorted by their offered ETH bribe tip, and submits the bundle to Ethereum block builders (eth_sendBundle).

Is it safe to keep large amounts of ETH in a Banana Gun or Maestro wallet?

No. Because Telegram trading bots manage private keys server-side (or through custodial web enclaves) and have historically been targeted by multi-million-dollar exploits, you should only ever keep small, active session funds in a burner wallet and withdraw profits to a cold hardware wallet immediately after trading.

When should I switch from Banana Gun to a flat-fee sniper bot and group?

As soon as your monthly Ethereum sniping volume exceeds 5 to 10 ETH (for example, ten 0.5 ETH snipes per month), a 1% per-trade router fee costs you more than a flat-fee subscription—while also exposing your trades on a public retail router that anti-bot tokens blacklist. Switching to MEV DAO eliminates the 1% volume tax and gives you vetted launch calls in our Telegram group.
