Since the other thread is old and crowded let's propose again a simple schema for Stellar links based on the same operation definitions for the platform:
stellar:{operation}?{parameters}
The most used would be payments:
stellar:payment?destination=G123&asset=native&amount=10.00&memo=Hello
* While memo is not part of the Payment operation it is widely used so it pays to have it included
* Also asset=native would be default so it can be omitted
So a request for payment operation in its simplest form:
stellar:payment?destination=G123&amount=10.00
But how about an invitation to set inflation destination so pools can call for action with a link and wallets doing their job?
stellar:setOptions?inflationDest=G123
Or how about an offer for assets for easy trading?
stellar:manageOffer?selling=XRP&buying=XLM&amount=10&price=0.5
If we stick to the Stellar specs then there is no standard to define since it is already available for everybody to implement. Adoption starts with wallet developers.
What do you think?
