Through the hive-engine market. Later on, we're planning to set up an official "redemption" system as well. meowcurator will send you 1 LEO and burn your 1 meowLEO in exchange.

In cases of meowLEO being cheaper on the market than LEO price (underpriced, basically) you can also arbitrage and buy that (either get rewards or redeem it for LEO later). Since no matter what happens, for meowcurator, 1 meowLEO is worth 1 LEO. For now, we're letting the market decide.
