Launching
A launch costs its creator the rent of the new accounts (mint, curve vaults, pool) plus the network fee, about 0.0135 SOL measured by simulation on 2026-11-10, plus any first buy. Rainfall charges nothing to launch.
Platform fees
Platform fees accrue in LaunchLab's platform vault and are claimed by the fee wallet. Half of every claim buys $RAIN and burns it, half funds the keeper. Each buyback and burn is listed with its transaction on the ledger.
