approveDelegation

function approveDelegation(address delegatee, uint256 amount) external

Parameters

Name	Type	Description
delegatee	address	The address receiving the delegated borrowing power
amount	uint256	The maximum amount being delegated.

delegationWithSig

function delegationWithSig(address delegator, address delegatee, uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) external

Delegates borrowing power to a user on the specific debt token via ERC712 signature

Parameters

Name	Type	Description
delegator	address	The delegator of the credit
delegatee	address	The delegatee that can use the credit
value	uint256	The amount to be delegated
deadline	uint256	The deadline timestamp, type(uint256).max for max deadline
v	uint8	The V signature param
r	bytes32	The R signature param
s	bytes32	The S signature param

borrowAllowance

function borrowAllowance(address fromUser, address toUser) external view returns (uint256)

Returns the borrow allowance of the user

Parameters

Name	Type	Description
fromUser	address	The user to giving allowance
toUser	address	The user to give allowance to

Return Values

Parameters

Name	Type	Description

delegatee	address	The address receiving the delegated borrowing power
amount	uint256	The allowance amount being delegated.

function _decreaseBorrowAllowance(address delegator, address delegatee, uint256 amount) internal

Decreases the borrow allowance of a user on the specific debt token.

Parameters

Name	Type	Description
