LibCommon

It contains an enum and structs that define the data structures for passing arguments and information related to bridge operations, including bridge types, payload data, recipient network IDs, amounts, asset addresses, and transfer keys. The purpose of these data structures is to provide a standardized format for handling bridge operations and their associated parameters in the contract or system that uses them.

BridgeType

This is an enumeration that defines two values: Wormhole and Stargate. It is used to represent different bridge types.

enum BridgeType {
    Wormhole,
    Stargate,
    Celer
}

BridgeArgs

struct BridgeArgs {
    BridgeType bridgeType;
    bytes payload;
}

Field	Type	Description
bridgeType	BridgeType	An instance of the BridgeType enum that specifies the type of the bridge.
payload	bytes	A bytes field that contains additional payload data for the bridge operation.

BridgeInArgs

struct BridgeInArgs {
    uint16 recipientNetworkId;
    BridgeArgs bridgeArgs;
    uint256 amount;
    address toAssetAddress;
    TransferKey transferKey;
}

Field	Type	Description
recipientNetworkId	uint16	An unsigned 16-bit integer that represents the ID of the recipient network.
bridgeArgs	BridgeArgs	An instance of the BridgeArgs struct that contains the bridge arguments.
amount	uint256	A uint256 value that represents the amount being bridged.
toAssetAddress	address	An address that specifies the address of the asset on the recipient network.
transferKey	TransferKey	An instance of the TransferKey struct that represents a transfer key for the bridge operation.

BridgeOutArgs

struct BridgeOutArgs {
    BridgeArgs bridgeArgs;
    Transaction transaction;
    TransferKey transferKey;
}

Field	Type	Description
bridgeArgs	BridgeArgs	An instance of the BridgeArgs struct that contains the bridge arguments.
transaction	Transaction	An instance of the Transaction struct that represents the transaction for the bridge-out operation.
transferKey	TransferKey	An instance of the TransferKey struct that represents a transfer key for the bridge operation.

RefundArgs

struct RefundArgs {
    uint16 recipientNetworkId;
    uint256 amount;
    address toAssetAddress;
    TransferKey transferKey;
    BridgeArgs bridgeArgs;
    bytes payload;
}

Field	Type	Description
recipientNetworkId	uint16	An unsigned 16-bit integer that represents the ID of the recipient network.
amount	uint256	A uint256 value that represents the amount being refunded.
toAssetAddress	address	An address that specifies the address of the asset on the recipient network.
transferKey	TransferKey	An instance of the TransferKey struct that represents a transfer key for the bridge operation.
bridgeArgs	BridgeArgs	An instance of the BridgeArgs struct that contains the bridge arguments.
payload	bytes	The bytes that contain some message which are required while bridging.
