LibCeler

These functions manage the configuration, addition, and execution of Celer bridge transactions. They handle the interaction with the Celer bridge and logs events related to their actions. Additionally, they decode payload data and perform the necessary transaction actions for both inbound and outbound asset transfers between Celer networks and other networks. The functions include validations to ensure the Celer bridge is active and functional before executing these transactions.

updateSetting():

Updates the Celer bridge settings in the application storage.

Input

Field	Type	Description
celerBridgeSettings	CelerBridgeSettings	struct CelerBridgeSettings { address messageBusAddress; }

addCelerChainIds():

Adds Celer chain IDs to the application storage.

Input

Field	Type	Description
networkIds	uint16[]	An array containing identifiers for networks.
chainIds	uint64[]	An array containing chain identifiers corresponding to the networks in networkIds.

addMagpieCelerBridgeAddresses():

Adds Magpie Celer bridge addresses to the application storage.

Input

Field	Type	Description
networkIds	uint16[]	An array containing identifiers for networks.
magpieCelerBridgeAddresses	bytes32[]	An array containing chain identifiers corresponding to the networks in networkIds.

decodeBridgeInPayload():

Decodes the payload used in a Celer bridge transaction.

Input

Field	Type	Description
bridgeInPayload	bytes	A bytes array that represents the input payload.

Output

Field	Type	Description
bridgeInData	CelerBridgeInData	struct CelerBridgeInData { uint32 slippage; uint256 fee; }

bridgeIn():

Executes the bridge in operation for a Celer bridge, facilitating the transfer from one network to another.

Input

Field	Type	Description
bridgeInArgs	BridgeInArgs	struct BridgeInArgs { uint16 recipientNetworkId; BridgeArgs bridgeArgs; uint256 amount; address toAssetAddress; TransferKey transferKey; }

bridgeOut():

Performs the bridge out operation, transferring assets from the Celer network back to the original network.

Input

Field	Type	Description
bridgeOutArgs	BridgeOutArgs	struct BridgeOutArgs { BridgeArgs bridgeArgs; Transaction transaction; TransferKey transferKey; }

Output

Field	Type	Description
amount	uint256	The amount received after the bridgining
