Your wallets buy in slot zero.
Create, dev buy and up to 16 wallets land as one Jito bundle, in the same slot as your coin.
Nobody gets in between.
Send the create on its own and bots buy before your wallets do. Zeroslot puts all of it in one slot.
Plan the bundle before you send it.

Questions
What does atomic mean here?
The create, your dev buy and every bundle wallet buy go out as one Jito bundle. Validators run all of it in the same slot, in order, or none of it. A bundle that does not land costs no tip.
How many wallets can buy in the launch?
Your dev wallet plus up to 16 bundle wallets. A bundle holds five transactions: the first carries the create and dev buy, the other four carry up to four wallets each. Each buyer costs about 109k compute units, so four per transaction is the ceiling.
Can Zeroslot move my funds?
No. Your password is turned into two keys in your browser. Only the sign-in key reaches us. The key that encrypts your wallets never leaves the browser, and every transaction is signed there.
What does it cost?
No platform fee. You pay the network: a Jito tip when the bundle lands, token account rent and pump.fun's own fees. The lookup table rent of about 0.01 SOL can be reclaimed from the coin page.
What happens after the coin graduates?
The coin page routes trades through Jupiter automatically, still with no platform fee. Creator fees can be claimed from the same page.
