When a user supplies funds to the protocol, they receive rTokens. We use the following formula (as per EIP 4626) to calculate the number of tokens minted to the user.
The formula uses existing total rTokens supply and Total asset supply to decide the quantity of rTokens to be minted as per the user deposit.
Assets_lent => Assets borrowed by borrower contract to issue loans to the user
Interest_accrued => Interest recievable by suppliers since last update
The contract exposes the following features for user and open contracts to interact with:
- 1.User: Technically, a user can usually perform 3 main actions with supplier contract: Deposit, Withdraw & Transfer. User can further use the received rTokens as collateral to borrow or stake to earn higher yield.

- 2.Open: The supply contract provides special privileges to the Open contract to allow it for some book-keeping. These options include:
- Accrue the interest
- Lock/unlock supply - to prevent the transfer of collateralised supply
- Transfer & withdraw supplied funds on the users behalf - to liquidate the loan
- Borrow and repay - to utilise funds to issue & close loans
