func (Keeper) Transfer

func (k Keeper) Transfer(goCtx context.Context, msg *types.MsgTransfer) (*types.MsgTransferResponse, error)

Transfer defines a gRPC msg server method for MsgTransfer. This implementation overrides the default ICS20 transfer's by converting the ERC20 tokens to their Cosmos representation if the token pair has been registered through governance. If user doesn't have enough balance of coin, it will attempt to convert ERC20 tokens to the coin denomination, and continue with a regular transfer.
