Harvest lockup is a rewards lockup mechanism that 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 TENGU-BUSD and TENGU-BNB farm is 2 hours. Farmers who stake in the TENGU-BUSD and TENGU-BNB farms can only harvest (claim their rewards from farming) every 2 hours.
For all other farms the harvest lockup is 8 hours.
You can check the harvest lockup on each farm card.
To clarify, the harvest lockup only locks users' farming rewards. The tokens and LP tokens staked in farms can be withdrawn anytime.
