flashLoan

Allows user to take flashloans from the wrapper

This function is guarded by the nonReentrant modifiers. we offer unwanted tokens (sellingToken) in exchange of underlying tokens

function flashLoan(
    address receiver,
    uint256 amount,
    bytes memory encodedData,
    bytes memory signature,
    bytes memory params
) external nonReentrant stopFlashLoan onlyNotSanctioned(receiver) onlyNotSanctioned(_msgSender());

Parameters

Name	Type	Description
receiver	address	The address of the receiver.
amount	uint256	The amount of underlying assets to flashloan.
encodedData	bytes
signature	bytes
params	bytes	The parameters for the flashloan. Used by the receiver contract(Aave's interface)

getConversionRate

function getConversionRate(PriceFeed memory priceFeed, uint256 t1, uint256 t2, uint256 x1, uint256 x2)

verifyAndDecode

Verifies the provided signature and decodes the encoded data into ScheduledRebalance struct.

It recovers the address from the Ethereum signed message hash and the provided signature. If the recovered address doesn't match the signersAddress, it reverts the transaction. If the signature is valid, it decodes the encodedData into a ScheduledRebalance struct and returns it.

function verifyAndDecode(bytes memory signature, bytes memory encodedData) private view returns (PriceFeed memory);

Parameters

Name	Type	Description
signature	bytes	The signature to be verified.
encodedData	bytes	The data to be decoded into a ScheduledRebalance struct.

Returns

Name	Type	Description
<none>	PriceFeed	data A ScheduledRebalance struct containing the decoded data.
