# launcher

> block 0 token launching with jito bundles

deploy pump.fun tokens with atomic jito bundles. all transactions land in block 0 or fail together.

## overview

the launcher uses native pump.fun instructions (not api) to create tokens with guaranteed block 0 execution. dev buy, bundle wallets, swarm wallets, and snipers all execute atomically via jito.

## key features

<CardGroup cols={2}>
  <Card title="block 0 bundles">
    token create + dev buy + bundle buys in one atomic jito bundle. no front-running possible.
  </Card>

  <Card title="bundle + swarm">
    launch with swarm wallets for maximum holder count. all wallets buy in block 0.
  </Card>

  <Card title="bundle + snipe">
    sniper wallets fire immediately after bundle with same blockhash. targets block 0-1.
  </Card>

  <Card title="auto creator fees">
    automatically claim pump.fun creator fees from all launched tokens.

## how it works

### 1. metadata upload

your token image and metadata are uploaded to ipfs via pinata. this happens before any blockchain interaction.

### 2. bundle construction

the bot builds transactions:

* create\_v2 (token creation)
* extend\_account (required for pump.fun)
* dev buy (your initial purchase)
* bundle wallet buys (additional wallets)

all transactions use the same blockhash.

### 3. jito submission

the bundle is submitted to jito block engine. jito validators include all transactions atomically in block 0.

### 4. sniper firing (optional)

if bundle+snipe mode is enabled, sniper transactions fire immediately after bundle submission using the same blockhash to target block 0-1.
