Hi,
For some of the wallets, depending on which service one is using, a memo/note/tag is needed. A field to place one would be a great addition.
Some that I know which have this feature:
* BNB (Benance)
* XLM (Stellar Lumens)
* XRP (Ripple) – speaking of which, can this be added in the list too?
* STEEM
Thank you!
