Overview

Package transfer implements the packet data structure, state machine handling logic, and encoding details for the transfer of fungible tokens over an IBC channel between two modules on separate chains. This implementation is based off the ICS 20 specification (https://github.com/cosmos/ibc/blob/main/spec/app/ics-020-fungible-token-transfer)

Functions

func ValidateTransferChannelParams 

func ValidateTransferChannelParams(
	ctx sdk.Context,
	transferkeeper keeper.Keeper,
	order channeltypes.Order,
	portID string,
	channelID string,
) error

ValidateTransferChannelParams does validation of a newly created transfer channel. A transfer channel must be UNORDERED, use the correct port (by default 'transfer'), and use the current supported version. Only 2^32 channels are allowed to be created.
