Squad launches on pump.fun

Your squad buys first.
Not the snipers.

Open a lobby, your friends join with their own wallets, and every wallet buys in the same block as your coin. Nobody shares a key.

Two Phantom signatures — one signs you in, one unlocks your saved wallets. Neither moves any funds.

Keys stay in your browserFree rehearsalsUp to 10 people

Built for launching together

Everything a squad needs, nothing it has to trust anyone with.

Every wallet in block 0The create and every squad wallet's buy go out together, each as its own transaction.
Squad LockTick Lock on any wallet and its tokens are locked on Streamflow right after it buys.
Split the feesCreator fees split between everyone in the squad, set on pump.fun for good.
Keys stay with youWallets are encrypted in your browser. Each person signs only their own buys.

Three steps to launch

Rehearse as often as you like — a rehearsal never touches the chain.

pump.fun callout

not signed in

Write your callout and press Pre-call. When the coin from your next launch lands in your ★ wallet, your callout posts on pump.fun by itself, retrying until pump.fun has the coin. Each person pre-calls their own.

pump.fun's callout reward rules ban coordinated buying or selling around calls; pre-calling is your own choice.
