# Harvest lockup

Harvest lockup is a unique and creative farming rewards lockup mechanism. This mechanism can help us limit the frequency of harvest to **prevent farming arbitrage bots** from constantly harvesting and dumping.

For example, the harvest lockup of the VIOLA-BUSD farm is 2 hours. It means that farmers who stake in the VIOLA-BUSD farm can only harvest (claim their rewards from farming) every 2 hours.
