I was wondering is there a way to send other people silver? If so how do I find it?

I was wondering because someone was helping me by giving me a ton of blueprints, that from what I've seen so far, would be quiet valuable. So I wanted to send them something since I've had some luck and got a few pets that can make a ton of silver in a little time.

If they sold you 1 stone for X amount of silver, then yes.

Otherwise maybe buy them something - pets and items off the Item Trades can be gifted.
