Vault allows you to stake Liquidity Pool (LP) tokens from other platforms (Eg. PancakeSwap) to earn other tokens on BabySwap. The LP tokens come from Liquidity pools of other platforms by adding tokens to provide liquidity.
Each vault has its own APR, depending on the value of LP tokens and the price of the token received.
Vault can give better rewards than Pools, but it comes with a risk of Impermanent Loss. It’s not as scary as it sounds, but it is worth learning about the concept before you get started. Check out this great article about Impermanent Loss from Binance Academy to learn more.
