APY Compounding Mechanics

APY Compounding Mechanics refers to the process where interest earned on a cryptocurrency deposit or liquidity position is reinvested back into the principal balance at specific intervals. In decentralized finance protocols, this occurs automatically through smart contracts that harvest rewards and immediately restake them.

Because the new total includes the previous interest, the base for the next interest calculation grows over time. This exponential growth model is a cornerstone of yield farming strategies.

The frequency of compounding, such as daily or hourly, significantly impacts the final effective annual yield. Investors must account for transaction costs, or gas fees, which can erode the benefits of frequent compounding.

Understanding these mechanics is essential for optimizing returns in liquidity pools and staking vaults.
