JustLend DAO Mainnet Contracts

JustLend DAO Protocol is a TRON smart contract protocol for supplying or borrowing assets. Through the jToken contracts, accounts on the TRON blockchain supply capital (TRX or TRC20 tokens) to receive jTokens or borrow assets from the protocol (holding other assets as collateral). The JustLend DAO jToken contracts track these balances and algorithmically set interest rates for borrowers. Check more info on Justlend DAO Whitepaper. 
Main Contracts
We detail a few of the core contracts in the JustLend DAO protocol.
CToken, CErc20 and CEther
The JustLend DAO jTokens which are self-contained borrowing and lending contracts, are deployed from the code of CToken and CEther contracts. CToken contains the core logic and CTrc20 and CEther add public interfaces for TRC20 tokens and TRX, respectively. Each jToken is assigned an interest rate and risk model (see InterestRateModel and Comptroller parts), and allows accounts to mint (supply capital), redeem (withdraw capital), borrow and repay a borrow. Each jToken is a TRC20-compliant token where balances represent ownership of the market.
Comptroller
The risk model contract validates permissible user actions and disallows actions if they do not fit certain risk parameters. For instance, the Comptroller enforces that each borrowing user must maintain a sufficient collateral balance across all cTokens.
GovernorAlpha
The administrator of the JustLend DAO Timelock contract. Holders of JST token may create and vote on proposals that will be queued into the JustLend DAO Timelock and then have effects on JustLend DAO jToken and Comptroller contracts. This contract may be replaced in the future with a beta version.
InterestRateModel
Contracts that define interest rate models. These models algorithmically determine interest rates based on the current utilization of a given market (that is, how much of the supplied assets are liquid versus borrowed).
ErrorReporter
Library for tracking error codes and failure conditions.
Exponential
Library for handling fixed-point decimal numbers.
WhitePaperInterestRateModel
Initial interest rate model, as defined in the Whitepaper. This contract accepts a base rate and slope parameter in its constructor.
Careful Math
Library for safe math operations.
SafeToken
Library for safely handling Trc20 interaction.
Staked TRX
The contract is used to stake TRX.
Energy Rental
The contract is used to rent energy.
How to Compile The Contract
You can get the compiler from here​
And rename the compiler executable file to solc512, then compile the contracts with these commands.
