user86975: Is it possible to use Signal or Telegram for crypto transactions? 
I heard CryptoCat messenger is for such needs, but interested in using those two mentioned above.

user63872: You can communicate transaction details to your counterparty using the app, but afaik neither of the messenger apps you mentioned have a cryptocurrency transfer system built into them. 
So you'll need a wallet app, but otherwise you can communicate with your counterparty through the messenger app (agree on the amount to be transacted, send a payment address, etc)
