LibWormhole
It provides functions for interacting with the Wormhole bridge in a decentralized exchange system.
WormhokeBridgeInData
the receipient chain id as per wormhole standard.
updateSettings()
updates the stargateSettings struct in the contract's AppStorage struct.
Input
normalize()
normalizes an amount from one decimal precision to another.
Input
decimals of the source asset
decimals of the target asset
amount that needs to be normalized
Output
the normalized amount
denormalize()
denormalizes an amount from one decimal precision to another.
Input
decimal of the source asset
decimal of the target asset
amount that needs to be denormalized
Output
the denormalized amount
getRecipientBridgeChainId
this function is responsible for extracting the recipient bridge chain ID from the provided bridge in payload.
Input
Payload necessary for bridging in.
Output
The receipient chain id fetched from the payload
bridgeIn
this function is responsible for executing the bridge-in operation using the Wormhole bridge. It performs dust management operations for token amounts, approves the spending of tokens, and calls the transferTokens function of the Wormhole bridge contract to initiate the token transfer. The recipient bridge chain ID, Magpie aggregator address, and timestamp-based nonce are provided as arguments to the transferTokens function.
Input
The network identifier of the destination chain
The amount that needs to be swapped
The final token that needs to be received
Output
The sequence received after a successful bridging in
bridgeOut
this function is responsible for executing the bridge-out operation using the Wormhole bridge. It verifies the token sequence, extracts the amount of tokens from the payload, performs denormalization if necessary, and completes the transfer by calling the completeTransfer function of the Wormhole bridge contract.
Input
Payload contains data that is necessary for bridging out
Output
The amount received after bridging out
