Paid in ETH, in the same transaction, before trading opens — so you're never sniped on your own coin. Buys as far up the curve as your ETH reaches; anything past the graduation ceiling is refunded automatically.
No tax — your coin trades clean, 0/0. Slide to add a fee; you keep 75% of everything it collects.
Free to launch — you only pay network gas. One transaction: no token approval, no authority grant. The dev buy (if any) rides in the same tx, ahead of the field — no cap, and any ETH past the graduation ceiling is refunded.
