Hi guys. I don’t know if this is possible or doable at all, but I would like to send an update over a channel e.g: transferring 10 tokens but identifying it with some kind of tag regarding the purchase i’m paying. Or, for example, a seller could request an update to sign for a buyer with attached information.
I tried to craft a signing function to pass to the channel.update method where I decode and deserialize the update TX, attach some object fields, and re encode it for the signTransaction method.
Unfortunately, this didnt succeed, failing with "Error: “invalid remainder” exception.
There is any alternative to what I’m trying to do?
Thanks in advance.
