Functions

func GetReceivedCoin

func GetReceivedCoin(srcPort, srcChannel, dstPort, dstChannel, rawDenom, rawAmt string) sdk.Coin

GetReceivedCoin returns the transferred coin from an ICS20 FungibleTokenPacketData as seen from the destination chain. If the receiving chain is the source chain of the tokens, it removes the prefix path added by source (i.e sender) chain to the denom. Otherwise, it adds the prefix path from the destination chain to the denom.

func GetSentCoin

func GetSentCoin(rawDenom, rawAmt string) sdk.Coin

GetSentCoin returns the sent coin from an ICS20 FungibleTokenPacketData.

func GetTransferAmount

func GetTransferAmount(packet channeltypes.Packet) (string, error)

GetTransferAmount returns the amount from an ICS20 FungibleTokenPacketData as a string.

func GetTransferSenderRecipient

func GetTransferSenderRecipient(packet channeltypes.Packet) (
	sender, recipient sdk.AccAddress,
	senderBech32, recipientBech32 string,
	err error,
)

GetTransferSenderRecipient returns the sender and recipient sdk.AccAddresses from an ICS20 FungibleTokenPacketData as well as the original sender bech32 address from the packet data. This function fails if:

  • the packet data is not FungibleTokenPacketData
  • sender address is invalid
  • recipient address is invalid
