The thing that’s really interesting about Decentralized Finance (DeFi) is that on top of the ecosystem, you can borrow and lend assets. And that, to a great extent, has to do with Ethereum smart contracts where assets, whether they’d be gold assets or commodities, are locked into contracts.
DeFi basically lets everyone take part in the ecosystem. You don’t have a banking system? No problem. You don’t have wallets? Create one easily, and not only take part in banking but lend your assets and get some kickback, or borrow assets with some collateral.
