Alpaca Finance is a popular farming tool on Binance Smart Chain. Earn yield by depositing tokens into a liquidity pool, which is a crowdsourced smart contract account that facilitates trades between assets on a DEX. Instead of traditional markets of buyers and sellers, DEX's like Alpaca Finance use Liquidity Pools to allow assets to be traded in an automatic manner. When you deposit into these pools you generate rewards based on the current Annual Percentage Yield.
