The majority of our vaults work on an compounding strategy. This sees vault rewards harvested and re-invested into the underlying asset. In the WEX-BNB example used previously, we staked WEX-BNB wLP's from WaultSwap. When these LP tokens are staked on WaultSwap they earn $WEX rewards. Our Vaults take this $WEX reward, sell it and use the earnings to purchase more BNB and add this to the total number of WEX-BNB wLP's from WaultSwap in the vault.
