Borrowing

Borrowers deposit collateral to specific tranches and borrow loan tokens against it. Each tranche has its own collateralToken, lltv, and oracle which is independent of the other tranches in the market.

Borrow

function borrow(
    MarketParams memory marketParams,  // The market parameters.
    uint256 trancheIndex,              // The index of the tranche to borrow from.
    uint256 assets,                    // The amount of assets to borrow (use 0 if borrowing by shares).
    uint256 shares,                    // The amount of shares to borrow (use 0 if borrowing by assets).
    address onBehalf,                  // The address to borrow on behalf of.
    address receiver,                  // The address to send the borrowed assets to.
    bytes calldata irmData             // The IRM data to pass during interest accrual.
) external returns (uint256, uint256);

Borrowers specify either assets or shares.

Accrues interest only for the specified tranche.

Borrow amount must be less than or equal to free supply for the tranche.

The borrower's position must remain healthy after the borrow.

Repay

function repay(
    MarketParams memory marketParams,  // The market parameters.
    uint256 trancheIndex,              // The index of the tranche to repay to.
    uint256 assets,                    // The amount of assets to repay (use 0 if repaying by shares).
    uint256 shares,                    // The amount of shares to repay (use 0 if repaying by assets).
    address onBehalf,                  // The address to repay on behalf of.
    bytes calldata data,               // Arbitrary data to pass to the callback (if any).
    bytes calldata irmData             // The IRM data to pass during interest accrual.
) external returns (uint256, uint256);

Borrowers specify either assets or shares.

Accrues interest only for the specified tranche.

Optional callback data for ILotusRepayCallback.

Supply Collateral

function supplyCollateral(
    MarketParams memory marketParams,  // The market parameters.
    uint256 trancheIndex,              // The index of the tranche to supply collateral to.
    uint256 assets,                    // The amount of collateral assets to supply.
    address onBehalf,                  // The address to supply collateral on behalf of.
    bytes calldata data                // Arbitrary data to pass to the callback (if any).
) external;

Supplies collateral increasing the borrower's capacity.

Does not accrue interest.

Optional callback data for ILotusSupplyCollateralCallback.

Withdraw Collateral

function withdrawCollateral(
    MarketParams memory marketParams,  // The market parameters.
    uint256 trancheIndex,              // The index of the tranche to withdraw collateral from.
    uint256 assets,                    // The amount of collateral assets to withdraw.
    address onBehalf,                  // The address to withdraw collateral on behalf of.
    address receiver,                  // The address to send the withdrawn collateral to.
    bytes calldata irmData             // The IRM data to pass during interest accrual.
) external;

Accrues interest only for the specified tranche.
