Harvest lockup is a unique and creative farming rewards lockup mechanism created by the PolyLion dev team. This mechanism can help us limit the frequency of harvest to prevent farming arbitrage bots from constantly harvesting and dump.
For example, the harvest lockup of the LION-USDC farm is 2 hours. It means that farmers who stake in the LION-USDC farm can only harvest (claim their rewards from farming) every 2 hours.
You can check the harvest lockup on each farm card.
