The protocol allows anyone to be a supplier. These supplied funds are then used to issue loans for the borrower. We make use of the ERC 4626 standard for our supply vault. When a user deposits funds to the corresponding vault, rTokens of that particular asset (Representational tokens) are minted to the user. These rTokens represent user shares in the deposit vault. We follow a similar logic in borrow token contract, though it is not designed to follow the 4626 standard (as it is not a vault). User will receive dTokens (Debt tokens) for borrowing and these tokens represent the share of total debt owed by the user to the protocol.

The above diagrams describe the basic actions a supplier and borrow can do. It shows how to borrow and supply contracts interact with each other.
