Implement a Lend/Borrow product

Create a DeFi protocol that allows users to lend their cryptocurrencies to earn interest or borrow assets by providing collateral.

zkSwap Finance has the potential to be a DeFi marketplace from zkSync ecosystem, and already offers many apps such as swap, bridge, stake, and liqquidity pools. A Lend/Borrow protocol would take the project to another level bringing huge transaction volume to the ecosystem.
