When depositing, users will have to approve 2 transactions, one to approve the Pickle Finance site as an approved user of your tokens, and the other to actually deposit those tokens into a jar. Once a user has deposited into the jar, that's it! The compounding (selling the specific rewards) is automatic. Some jar strategies will compound daily, while others may have to wait a few days to be compounded due to low balances, high gas costs, or lower APY. .
