DeFi holds the promise of creating financial products and services for anyone with a smartphone. The tool allows its users to transfer their funds from low-interest bank accounts, where inflation is already eroding the value of deposits, to funds linked to smart contracts. The funds held in these funds can be lent, borrowed or increased in value through a series of blockchain-based monetary mechanisms, including liquidity incentives from decentralised exchanges and synthetic derivatives. The annual percentage return can be 20% higher than traditional savings.
