Functions

supplyLogic

LOGIC ///

Implements supply logic.

function supplyLogic(address _poolToken, address _from, address _onBehalf, uint256 _amount, uint256 _maxGasForMatching)
    external;

Parameters

Name	Type	Description
`_poolToken`	`address`	The address of the pool token the user wants to interact with.
`_from`	`address`	The address of the account sending funds.
`_onBehalf`	`address`	The address of the account whose positions will be updated.
`_amount`	`uint256`	The amount of token (in underlying).
`_maxGasForMatching`	`uint256`	The maximum amount of gas to consume within a matching engine loop.

borrowLogic

Peer-to-peer supply /// Pool supply ///

Implements borrow logic.

function borrowLogic(address _poolToken, uint256 _amount, uint256 _maxGasForMatching) external;

Parameters

Name	Type	Description

`_maxGasForMatching`	`uint256`	The maximum amount of gas to consume within a matching engine loop.

_borrowAllowed

Peer-to-peer borrow /// Pool borrow ///

Checks whether the user can borrow or not.

function _borrowAllowed(address _user, address _poolToken, uint256 _borrowedAmount) internal returns (bool);

Parameters

Name	Type	Description

Returns

Name	Type	Description
`<none>`	`bool`	Whether the borrow is allowed or not.

Events

Supplied

EVENTS ///

Emitted when a supply happens.

event Supplied(
    address indexed _from,
    address indexed _onBehalf,
    address indexed _poolToken,
    uint256 _amount,
    uint256 _balanceOnPool,
    uint256 _balanceInP2P
);

Borrowed

Emitted when a borrow happens.

event Borrowed(
    address indexed _borrower,
    address indexed _poolToken,
    uint256 _amount,
    uint256 _balanceOnPool,
    uint256 _balanceInP2P
);

Errors

BorrowingNotEnabled

ERRORS ///

Thrown when borrowing is impossible, because it is not enabled on pool for this specific market.

error BorrowingNotEnabled();

UnauthorisedBorrow

Thrown when the user does not have enough collateral for the borrow.

error UnauthorisedBorrow();

SupplyIsPaused

Thrown when someone tries to supply but the supply is paused.

error SupplyIsPaused();

BorrowIsPaused

Thrown when someone tries to borrow but the borrow is paused.

error BorrowIsPaused();
