02 / SEALED
Only pump.fun buys.
During protection, standard wallets, terminals, and aggregators buy through the approved pump.fun route. Selling stays open.
5-60 MINUTES01 / THE SEALED LAUNCH
Pump buys first.
Everyone buys next.
OnlyPump gives every new token a short, visible protection window. Standard buys go through pump.fun. Then the capsule opens permanently.

The timer, not an operator, opens it.
The two halves travel along the capsule's original axis. No scattering, no manual unlock, no extension.
04 / OPEN FOREVER
Every route can buy.
DEXs, aggregators, bots, and terminals enter the same open market. The pump-only launch fee ends automatically.

Trading creates ETH revenue, not token taxes.
The token has zero transfer tax. Fees come from the V4 pool and the protected launch route.
1% on every swap
Each swap contributes a 1% ETH-denominated LP fee. It splits evenly at settlement without touching LP principal.
0.5%Creator share on each swap
0.5%Launchpad LP share on each swap
+0.5%
A 0.5% launchpad fee is paid in native ETH during launch protection and ends automatically.

Search by name, symbol, or full CA. Settlement sends ETH to the fixed creator revenue address shown on each launch.
Connect a creator walletYour launches will appear here.
Native ETH only
The 1% ETH-denominated liquidity fee is split into creator and protocol ledgers during every swap. Settlement never requires selling a launched token.
- No launched tokens are paid to either recipient
- LP principal is never part of the payout
One revenue address per settlement
One wallet confirmation settles the selected revenue address across all of its launches. Anyone can trigger it, but the caller cannot redirect the ETH.
- The creator revenue address is fixed at launch
- Failed direct payouts remain withdrawable by that address

Launch process
A single launch() call deploys a fixed-supply ERC-20, creates its Uniswap V4 pool, adds all 1 billion tokens as single-sided liquidity, and starts both protection windows.
- No presale, team allocation, or later mint function.
- Creators pay gas but do not need to seed ETH.
- Creator earnings come from trading fees, not a token allocation.
Protection windows

Cap: 24 hour default, 24 hour maximum

Protocol controls
- The interface verifies the disclosed route administrators, treasury, fee, approved pump.fun route, and deployed bytecode before it allows a wallet transaction.
- The route administrators can update the approved execution contract if pump.fun migrates. A configuration change disables launching until the interface is reviewed and updated.
- Each live launch is one-shot: its protection deadline and fee cannot be extended or repriced.
- Protocol operators cannot mint tokens, pause transfers, blacklist wallets, or withdraw LP principal.
