What is a yield optimizer
A yield optimizer is an automated service that seeks to gain the maximum possible return on crypto-investments, much more efficiently than attempting to maximize yield through manual means. Each vault has its own unique strategy for farming, which normally involves the reinvestment of crypto assets staked in liquidity pools.
At the most simple level Devil Finance vaults farm the rewards given from staked assets and reinvests them back into the liquidity pool. This compounds the amount of interest received and increases the amount staked that the yield is based on. A yield optimizer can repeat this process up to thousands of times a day. This fairly simple method is the principle reason behind the large APYs found on Devil Finance.
Compounding fees are amortized among all vault participants, giving back even more value to the users.
