Supply your Tez (XTZ) and Tezos tokens to Tezos Lending Pools. Suppliers earn compounded interest rewards based on a floating interest rate set by supply and demand of each respective asset pool.
Collateralize at least some of your Lending Pool positions, to enable yourself to borrow another type of asset. Borrowing debt owed is set by a floating interest rate for each respective asset pool.
Other future asset pools under consideration are pools for assets that have consistently-high daily trade volume. Without consistently high-volume each day, an asset pool would not function properly for DeFi lending system. If you would like another token pool to be considered, it must have evidence of consistently high daily volume.
