MagpieStargateBridgeV2

Similar to MagpieStargateBridge but the router address of the bridge has changed.

struct Settings {
        address aggregatorAddress;
        address routerAddress;
    }

Field	Type	Description
aggregatorAddress	address	Magpie Aggregator Address
routerAddress	address	Stargate Router Address

struct WithdrawArgs {
        uint16 srcChainId;
        uint256 nonce;
        address assetAddress;
        bytes srcAddress;
        TransferKey transferKey;
    }

Field	Type	Description
srcChainId	uint16	A uint16 value representing the source chain ID from which the withdrawal is initiated.
nonce	uint256	A uint256 value representing a unique identifier for the withdrawal transaction.
assetAddress	address	An address representing the asset address that is being withdrawn.
srcAddress	bytes	A bytes array representing the source address on the source chain.
transferKey	TransferKey	An instance of the TransferKey struct from the LibTransferKey library, which contains the network ID, sender address, and swap sequence associated with the withdrawal.

updateSettings():

to update the bridge settings. Only the contract owner can call this function.

Input:

Field	Type	Description
_settings	Settings	struct Settings { address aggregatorAddress; address routerAddress; }

withdraw():

to withdraw deposited funds. It checks the deposited amount based on the transfer key and asset address, clears the cached swap if the amount is zero, and transfers the amount to the aggregator address. Only the Magpie aggregator can call this function.

Input:

Field	Type	Description
withdrawArgs	WithdrawArgs	struct WithdrawArgs { uint16 srcChainId; uint256 nonce; address assetAddress; bytes srcAddress; TransferKey transferKey; }

Output:

Field	Type	Description
amountOut	uint256	The amount that is withdrawn.

sgReceive():

sgReceive is called by the Stargate router when assets are received from another chain. It increments the deposited amount based on the transfer key, asset address, and amount.

Input:

Field	Type	Description
transferKey.networkId	uint16	Network Id extracted from the TransferKey struct
transferKey.senderAddress	bytes	Sender Address extracted from the TransferKey struct
transferKey.swapSequence	uint256	Swap Sequence extracted from the TransferKey struct
assetAddress	address	An address parameter representing the address of the received asset.
amount	uint256	A uint256 parameter representing the amount of the received asset.
payload	bytes	A bytes calldata parameter containing encoded information about the transfer, including the TransferKey.
