the seven default buttons
Buttons
| Kind | Setting | What it sends |
|---|---|---|
| Buy | SOL amount, 0 to 50 | a pump.fun curve buy before graduation, a Jupiter route after |
| Sell | % of your balance, 1 to 100 | a curve sell or a Jupiter route to SOL; 100% also closes the token account and returns its rent |
| Launch | first buy in SOL | pump.fun create_v2 and your first buy, as one Jito bundle in one slot |
Each launcher also keeps its slippage, its Jito tip (0.00001 to 0.0005 SOL) and its priority multiplier (1x, 2x or 4x the network's recent fee). Keys are one letter or digit, unique per launcher. Hotkeys are off while you type in a field.
Save, share, clone
Save and share stores the launcher and returns /l/<id>. With the box ticked, your wallet address is stored as its author: when someone trades through your shared launcher, 20% of the 0.5% fee goes to you, paid in SOL by the hourly keeper. Opening a shared launcher loads its buttons into your wallet; Clone and save stores your own copy and counts the clone on the original. The gallery lists saved launchers.
