Answer: The harvest rate of every vault can vary, but most vaults typically have a harvest at least once every 24 hours. In some cases, it may take longer than 24 hours for a vault to have a harvest, such as USDD/DAI/USDC/USDT which have not had a harvest for more than 36 hours. It is important to keep an eye on the harvest rate of each vault to ensure that you are getting the most out of your investments.
