Bundling on an ETH chain versus on Solana

On Solana a bundle is a real primitive: several transactions submitted together, executed in order, all or nothing. If one fails, none land.

There is no equivalent here. Each transaction is independent. A volley of sixteen buys is sixteen separate transactions that happen to leave at the same moment, and some may land while others fail. Any interface that reports a launch as a single success or failure is hiding something — the honest report is per wallet.

Solana rewards priority fees and Jito tips with better placement. Robinhood Chain's sequencer orders by arrival, so the same money buys no advantage at all. Latency replaces spending as the thing worth optimising.

Pump.fun and its imitators mostly rely on speed and luck. pons prices the problem instead: a 99% opening tax that decays to nothing in three seconds, with a documented exemption list for team wallets.

That is a friendlier design to build against. Instead of racing a protection, you are using a parameter the protocol provides — which also means the tool does not break the next time the contracts are upgraded.

The curve arithmetic. Pump.fun and pons both price on a constant product with a virtual reserve, so intuitions about slippage, split orders and the cost of a large exit carry over almost exactly. If you know why a big sell hurts on Solana, you already know why it hurts here.
