LendingPool
Themis 2.0 upgrade primarily enhances the entire LendingPool, which is no longer just a simple non-custodial agreement for NFTs to lend and borrow, but a new model that allows depositors access to borrowing power with higher liquidity and a more complete risk control system.
In M0's LendingPool, t-tokens are minted/burned 1:1 when supplied/withdrawn by the user. t-tokens can be transferred normally. Some t-tokens can be treated as collateral, and there are some restrictions on tToken transfers when the user's account has debt.
Since the balance of tToken is controlled by LendingPool's algorithm, the balance of tToken held by the user is settled in real time with interest from LendingPool settlement.
Over-collateralized lending
LendingPool uses a form of overcollateralization. This is designed to ensure that the protocol will have sufficient liquidity at all times.
The use of the protocol requires the asset to first be approved
Supply
When the user clicks Supply, they can choose to deposit any balance amount of tokens, after which the user will receive tToken 1:1 as a credential.
Assets that can be used as collateral are automatically counted as collateral upon supply amount and may result in liquidation if there is a risk of debt. If a user has borrowed assets and does not want a collateral to be liquidated, the user needs to close the collateral himself.
When depositing, users will see the changes to their BorrowPower after depositing assets:
Each asset has a corresponding MaxLTV, which means that a deposit to this asset can borrow debt of the corresponding dollar value. For instance, assuming the LTV of DAI is 80%, then when a user deposits $100 in DAI, they will have access to $80 in borrowing power.
Each supplied asset has a corresponding LiquidationThreshold, which means that depositing this asset will increase the LiquidationThreshold. e.g. if the LiquidationThreshold of DAI is 90%, then depositing $100 of DAI will increase the overall account LiquidationThreshold to $90.
Each supplied asset has a corresponding LiquidationBonus, which means that if the asset is liquidated, your borrowing assets will be offset and you will be additionally deducted the corresponding percentage of collateral. For example, the Liquidation Bonus for DAI is 5%, you supply $100 in DAI, when the borrowing asset reaches $90 it will trigger liquidation, if liquidation happens, your $90 DAI will be used to offset the borrowing and $5 will be deducted from the reward to the liquidator. And at the end you will only be left with $5 in DAI.
The status of the user's assets is subject to change with the value of the collateral or borrowing assets, and the price provided by Oracle.
Borrow
Once the assets supplied by the user are used as collateral, they can be borrowed from the assets supplied by other users in the list. Borrowing at stable rate or variable rate will correspond to 1:1 casting for sToken or vToken.
The s/vToken grows with the LendingPool algorithm, so you will need to pay back more Tokens in the future to completely destroy the s/vToken. Borrowing interest is a reference.
After borrowing, users will see changes to their borrowings and risk alerts:
You are able to borrow multiple debts. Their dollar value will accumulate and the interest will grow over time.
The LiquidationThreshold of your debt value / value as collateral * the Loan Risk. When the Loan Risk reaches 100%, your debt can be liquidated by the liquidator and you can avoid this by paying it off early or adding collateral.
In addition to the growth of debts with the interest rate curve, the value of the collateral and the debt itself fluctuates somewhat, at a price provided by the Oracle. Therefore you may trigger liquidation risk due to fluctuations in the value of the collateral or borrowings.
E-Mode（Efficiency Mode）
Some Token Categories have E-Mode mode between them, which can improve collateral efficiency for a short time. You can turn it on or off at the Borrow list.
On and off, before E-Mode the user must have no debt and the number of Categories that can be borrowed will be limited
When E-Mode is turned on, users will see the list change:
Only the collateral value of stablecoins is counted as collateral and the Borrow list can only borrow stablecoins;
You can use E-Mode parameters such as MaxLTV of 97% and LiquidationThreshold of 98.5%, LiquidationBonus is usually only 1%.
FlashLoan
Themis 2.0 also supports the FlashLoan, which enables unsecured loans by fetching contracts, but the borrowing and repayment must be done in one block, otherwise the FlashLoan will be reverted. This feature is mainly aimed at users who are liquidators.
For the interface call of FlashLoan part, you can refer to our developer documentation
Numeric Description
Dashboard
Contains My Supply, My Borrowing, Loan Risk, Net APY, Reward
My Supply i.e. all supply balances.
My Borrowing is the balance of all borrowings.
Loan Risk is the risk value, when Loan Risk is greater than 100%, the account will be in liquidation.
Net APY is the overall annualized rate of return, the combined annualized rate of return on deposits - cost of borrowing.
Reward i.e. the sum of all mining rewards of M0.
Supply Markets & My Supply Dashboard

Asset is the type of asset;
APY is the current estimated annualized return on the deposit;
Reward displays the current estimated reward for deposits of that asset type;
Wallet is the balance of the wallet and Balance is the balance of the supply amount;
Can be Collateral is whether the asset can be used as collateral, and Collateral is the collateral status.
My Supply displays the asset type using the tToken icon
