How it works
Bundle tech: how multi-wallet, same-block buys work
Bundle tech is the set of methods that put a token’s creation and buys from several wallets into the same block, in a fixed order, all or nothing. On Solana it is an atomic bundle sent with a tip. On EVM chains it is one EIP-7702 transaction that carries ERC-4337 operations.
The problem the technology solves
Blocks are processed in order, and anyone can send a transaction between two of yours. A creator who creates a token in one transaction and buys in the next leaves a gap, and snipers use it. Same-block buying is about closing that gap for the creator’s own wallets.
You may see the term “multi-snipe tech” for this. Here it means one thing: your own token’s creation and your own wallets’ buys sent together, which is multi-wallet buying in one block.
Solana: an atomic bundle
A bundle is a short list of transactions that validators run together, in the order given, or not at all. The relay that carries it is paid with a tip in the last transaction.
- Ballistic’s Block-0 bundle holds the token’s creation with the dev buy, at most two buyer wallets’ buys and the tip: four transactions on the default relay, five on others.
- The tip is 0.001 SOL on the default relay, the relay’s minimum, fixed when the plan is saved. The funding figure counts one tip for every bundle.
- After the first bundle, the rest of the supply is handed to further wallets. Each hand-off is its own bundle, with the sell and the buys it pays for in the same slot, and holder buys are spaced about 16 seconds apart.
EVM chains: EIP-7702 and ERC-4337
EVM chains have no bundle format like Solana’s, so the bundling happens inside one transaction. EIP-7702 lets the deployer wallet run smart-account code for that transaction. The code calls the launchpad’s create, with the dev buy, and then the ERC-4337 entry point.
Each buyer’s buy is its own ERC-4337 operation, signed by that buyer’s wallet, so explorers show distinct buyers rather than one wallet. If the operations cannot validate, the transaction reverts and the create goes with it. This is the one rail Ballistic uses for Block-0 on Pons (Robinhood Chain) and flap.sh (BNB Chain).
The two methods side by side
| Solana | EVM chains | |
|---|---|---|
| Unit | A bundle of transactions | One transaction |
| How order is kept | Validators run the list in order | The calls run in order inside one transaction |
| If something fails | The whole bundle is dropped | The transaction reverts, the create with it |
| Extra cost | A tip to the relay (0.001 SOL on the default relay) | Gas for the one transaction |
| Buyers on chain | Separate wallets | Separate wallets, each its own signed operation |
What the technology guarantees, and what it does not
- It guarantees order and atomicity: the creation and your buys land together, or none of it does. A launch never lands half done.
- It needs the money in place first, which is why Ballistic funds every wallet at a separate funding stage before launch.
- It does not guarantee a price, volume or profit, and it does not change what holders can see on chain.
- It has a size limit. Block-0 on Ballistic carries the dev buy and two buyer wallets in the launch itself, on every chain. A buy two wallets cannot carry is refused at setup, never bought smaller.
Where Ballistic uses it
The mode is called Block-0, offered on pump.fun, Pons, flap.sh and StonkFun. For the category view see memecoin bundler; for the steps see how to bundle a memecoin. Fee: 5% when funds leave a launch wallet, nothing on new funds to launch.
Questions
What is bundle tech?
The methods that send a token’s creation and several wallets’ buys in the same block, in order and all or nothing: an atomic bundle on Solana, one EIP-7702 transaction on EVM chains.
What is multi-snipe tech?
A loose name for buying from several wallets at once. In this page it means your own wallets’ buys inside your own token’s launch.
Why does the order of transactions matter in a launch?
A token on a bonding curve is cheapest at the start and each buy raises the price. Whoever buys first pays least, so a gap between creation and buy lets bots go first.
Can a bundle land partly?
No. A bundle on Solana is dropped whole if any part fails, and the EVM transaction reverts whole, the creation included.
Why does Ballistic carry three wallets in the launch and not dozens?
It is a design rule: the dev buy and two buyers go in the launch itself, and the rest of the supply is handed on afterwards. The two buyers split the configured buy evenly.
