What Is the Pump.fun Bundle Bot?
OpenLiquid's Pump.fun Bundle Bot creates your token and buys it across multiple wallets in a single atomic transaction at launch. Every launch runs through our advanced, MEV-resistant smart contracts, so token creation and all wallet buys settle in the same block — your wallets are guaranteed the first positions and snipers, sandwich bots, and front-runners are locked out. It works directly in your browser with no code, and bundle bots are also available for Ethereum, BNB Chain, Base, and other networks.
How to Launch with the Bundle Bot
Launching with the Bundle Bot takes a few minutes. You enter your token details, add the wallets that should buy at launch, connect your wallet, and click Launch. The bot creates the token and executes every wallet's buy in one atomic transaction — no code required.
How it works, in simple steps
- Enter your token name, symbol, and (optionally) a logo.
- Add your buy wallets — upload a CSV file or let the bot generate them for you. Download the ready-made CSV template to fill in your own.
- Set how much each wallet should buy (per wallet, or one amount for all).
- Connect Phantom or MetaMask and pay the flat 5 SOL fee.
- Click Launch — your token is created and every wallet buys in the same block.
Save your wallet CSV carefully. Your wallets are generated in your browser and only you ever have access to the secret keys — they are kept private and we never see, store, or transmit them. That also means we cannot recover them for you. Download the CSV and back it up somewhere safe.
What you get
- A brand-new live token on your chosen chain.
- Your wallets buying in the same block as the launch, before any sniper.
- A downloadable CSV of all your wallets and their secret keys — you keep full control.
- On-chain confirmation showing each wallet's buy and transaction details.
Step 1: Choose your chain
At the top of the launcher, pick the network you want to launch on — Pump.fun (Solana), EVM (Ethereum / Base / BSC), or Four Meme (BNB Chain). The form adjusts to that chain automatically.
Step 2: Enter your token details
Fill in your token's Name, Symbol (ticker), and an optional Description and logo image. A live character counter shows the limits for each field — Name up to 32 characters and Symbol up to 10 — so your details are always accepted on-chain. Enter exactly what you want to appear; what you type is what gets deployed.
Step 3: Add your wallets
Add the wallets that should buy your token at launch. The easiest way is to upload a CSV file: click Download template to get the correct format, fill in one row per wallet (Wallet ID and Secret Key), then click Upload CSV. You can also paste wallet keys directly. Set a buy amount for each wallet, or use the default buy field to apply the same amount to all of them.
Step 4: Connect your wallet
Click Select Wallet and connect with Phantom or MetaMask. This is the wallet that pays the service fee and signs the launch.
Step 5: Review & launch
Check the summary — your token details, the wallets that will buy, and the flat 5 SOL service fee — then click Launch. The token is created and all wallet buys execute together in the same block, so your wallets get the first positions before any sniper. If anything in the bundle fails, the whole transaction reverts and no funds are spent beyond network fees.
Supported Launchpads
OpenLiquid's Bundle Bot is live on Pump.fun (Solana), Four Meme (BNB Chain), and direct DEX launches on Ethereum, Base, and BNB Chain. The bot handles each platform's launch mechanics automatically.
Anti-MEV & Anti-Sniper Protection
MEV is the value predatory bots extract by reordering, inserting, or front-running transactions — the mechanism behind sniping and sandwich attacks. OpenLiquid's advanced smart contracts neutralize it. Token creation and every wallet buy execute as one atomic, indivisible transaction in the same block, so there is no gap for a bot to slip into — your wallets buy first at the lowest price, or the entire bundle reverts.
Multi-Wallet Coordination
The Bundle Bot manages up to 500 wallets per bundle, each configurable with different buy amounts. Wallets can be auto-generated by the bot or imported from your own key pairs. After execution, tokens and remaining SOL can be consolidated to a single wallet or left distributed.
Auto-Generated Wallets
The simplest approach is to let OpenLiquid generate wallets for you. You specify the number of wallets and the total budget, and the bot creates fresh wallets, distributes SOL among them, and prepares them for bundling. After the session, remaining SOL and purchased tokens can be consolidated back to your primary wallet with a single command.
Imported Wallets
If you want to use wallets you already control, you can import private keys through the bot's encrypted import flow. This is useful when you want tokens distributed to specific wallets for community management, team allocation, or specific wallet strategies. Imported wallets are stored encrypted and can be removed from the bot at any time.
Wallet Distribution Strategy
The buy amount for each wallet can be configured individually. Common distribution strategies include equal splits (each wallet buys the same amount), tiered allocation (some wallets buy more to serve as "whale" holders while others buy smaller amounts), and random distribution (the bot assigns random amounts within a specified range). The distribution strategy affects how the token's holder list appears on block explorers and aggregators.
A well-distributed holder list — with multiple wallets of varying sizes — looks more organic than a small number of wallets holding equal amounts. OpenLiquid recommends using between 10 and 100 wallets with a tiered distribution for optimal holder list appearance on DexScreener and Solscan.
Pricing
OpenLiquid charges a flat platform fee of 5 SOL per bundle launch. There are no subscriptions, no monthly fees, and no percentage cut of your buys. Network gas and priority fees are the only additional costs.

Frequently Asked Questions
A bundle bot is an automation tool that combines multiple wallet buy transactions into a single atomic transaction (a "bundle") on the blockchain. This ensures that all specified wallets purchase a token simultaneously in the same block, preventing front-running and sniping. Bundle bots are primarily used during token launches, where getting early positions across multiple wallets is critical for launch coordination.
OpenLiquid's Bundle Bot works across the major launch venues on Solana as well as Ethereum, BNB Chain, and Base. Each platform has different launch mechanics — bonding curves and AMM pools — and the bot handles the platform-specific requirements automatically.
OpenLiquid's anti-MEV smart contracts bundle your token creation and every wallet buy into one atomic transaction that settles in a single block. Because the sequence is indivisible, no sniper, sandwich bot, or front-runner can insert a transaction before your wallets — they are guaranteed the first, lowest-price positions, or the entire bundle reverts.
MEV (Maximal Extractable Value) is the profit predatory bots extract by reordering, inserting, or front-running transactions — the mechanism behind sniping and sandwich attacks. OpenLiquid's advanced smart contracts neutralize this by executing your launch atomically with private bundle submission and priority block inclusion, leaving zero window for bots to extract value from your launch.
OpenLiquid charges a flat platform fee of 5 SOL per bundle launch. There are no subscriptions, no monthly fees, and no percentage cut of your buys. Network gas and priority fees are the only additional costs.
