Inherits: IInterestRatesManager, MorphoStorage

Author: Morpho Labs.

Smart contract handling the computation of indexes used for peer-to-peer interactions.

This contract inherits from MorphoStorage so that Morpho can delegate calls to this contract.

Functions

updateIndexes

EXTERNAL ///

Updates the peer-to-peer indexes and pool indexes (only stored locally).

function updateIndexes(address _poolToken) external;

Parameters

Name	Type	Description
`_poolToken`	`address`	The address of the market to update.

_getPoolIndexes

INTERNAL ///

Returns the current pool indexes.

function _getPoolIndexes(address _underlyingToken)
    internal
    view
    returns (uint256 poolSupplyIndex, uint256 poolBorrowIndex);

Parameters

Name	Type	Description
`_underlyingToken`	`address`	The address of the underlying token.

Returns

Name	Type	Description
`poolSupplyIndex`	`uint256`	The pool supply index.
`poolBorrowIndex`	`uint256`	The pool borrow index.

_computeP2PIndexes

Computes and returns new peer-to-peer indexes.

function _computeP2PIndexes(Params memory _params)
    internal
    pure
    returns (uint256 newP2PSupplyIndex, uint256 newP2PBorrowIndex);

Parameters

Name	Type	Description
`_params`	`Params`	Computation parameters.

Returns

Name	Type	Description
`newP2PSupplyIndex`	`uint256`	The updated p2pSupplyIndex.
`newP2PBorrowIndex`	`uint256`	The updated p2pBorrowIndex.
