The system is based on a vault contract, that stores SPL tokens from individual wallets or from smart contracts. It is possible to deposit, withdraw or transfer funds using a vault. Also, it gives a couple of additional features: - generating yield from flash loans and strategies(special small smart contract, that could be written for individual SPL, and assigned to this token in the vault for all depositors). - give special permission for the external whitelisted contract to use depositors` funds from vault storage. The lending contract uses a vault contract to store user collaterals and stablecoins, allows intelligent borrowing and repaying of position, tracks the amount of the available loans, and gives a possibility to liquidate insolvent positions.
