Pump.fun Bundler

Launch a Pump.fun coin and buy it from many wallets in the same block — one atomic Jito bundle of up to 5 transactions. Plan every wallet’s tokens on the real bonding curve before anything is signed.

Unlocking the browser vault…

How the bundle is built

The first transaction creates the coin (create_v2) and makes the dev buy; the next ones carry the buyers, four per transaction, and the last one pays the Jito tip. An address lookup table, created in the prepare step, keeps each wallet to about 155 bytes.

Why 18 wallets

Solana caps a transaction at 64 instructions, inner calls included. A Pump.fun buy with its token account costs 15 of them, so a transaction holds 4 buyers and the launch transaction the dev plus 2 (plus 1 in mayhem mode). Five transactions: 18 buyers and the dev.

Curve-exact planning

Each buy moves the bonding curve for the next one. The planner replays the program’s math in order, so before you sign you see the exact tokens, % of supply and SOL cost of every wallet, the share held by the whole bundle and the balance each wallet needs.

After the launch

Follow holdings and PnL per wallet, sell a percentage from selected wallets in one bundle, and sweep SOL, tokens and rent back to your main wallet. The lookup table can be closed afterwards to refund its rent.

Existing coins too

Switch to “Existing coin” to bundle-buy or sell a coin that is already trading: on its Pump.fun curve (20 wallets per bundle) or on PumpSwap after migration (20 buyers, WSOL pre-wrapped). Every transaction is simulated against the live pool first.
