Tip bots like any other instant service requires a solid foundation, ie scalability is to be solved from the ground up in day one, as well as availability. Especially a tipping service requires business critical availability since people get frustrated when it doesn't work. And frustrated people are bad for the success of the service. What also is very important is the absolute flawless handling of the tips, ie once accepted by the system, it shall never be lost, so data redundancy is required. @klye will the tip administration and value recording be done on the Steem blockchain? Or will the service gets its own DB?

Shouldn't a tipping purse be something that Steemit, Inc. can integrate on the site through the UI? I know I've mentioned this in the past - having an option to fill a smaller purse with an amount of STEEM/SBDs that can be tipped to users on the post with the click of a button when logged in with the posting key. Do you think that would be feasible as a wallet/UI function?

If this could be done, then it would also help bring in more potential earnings for older posts that are past the payout window...while the reader is right there on the post. (Of course, this would also assume that older posts can actually be found by simple navigation around the platform, but that's another development that needs to be tackled.)

I'm thinking I might flat fee it.. Seems to be what most would prefer!

Might be a little over tired having been up all night working on @tippy.. If I misinterpreted or botched what ideas you'd put forward to me when brainstorming my apologies captain!

There are risks as you mentioned when dealing with user funds as well as risk that government may take notice and try and ding operators for transmitting money without a license. APpreciate the insight and knowledge you've shared with me as well as the support of my STEEM service development. <3

What about autotipping by upvotes? This is implemented in **[Dobrobot in Golos](https://golos.io/@dobrobot/transfers)**. Works fine for me! On each my upvote Dobrobot transfers 5 Golos to user which is upvoted by me.

I would launch with either: absolute contant fee, or constant percentage. The advantage of the later is that someone who want s to tip a really low amount can do that without paying up to 100%+ on commission. Since we have many many mini mini mini minnows int he community making a couple of cents on their post, I would suggest to go with a fixed percentage at start. Be aware your service may get a lot of hits when introducing such pricing strategy, bot may be created that tip 1.000s of tips within seconds, maybe sending 1000 account each 0.001 Steem. So have a plan ready how to mitigate this when it happens. You do not want to have an real outage on your service. So when your service is not able to handle many tx per second, you may want to introduce with a tx fee constant in absolute value, this will reduce the amount of tips generated. Oh, from engineering point of fee, think how you can throttle the tip requests, with meaningful feedback to the tippers when their tips are not possible to be accepted.

this is what I got in my wallet:
3 hours ago	Receive 0.099 STEEM from tippy	Tip from @klye via @tippy memo: Text to Tip Service - 1.00% Fee: 0.001

This works!

Can you make the command like this? "**@tippy edje 0.1**"?

This makes it more simple. Tip will then always by Steem, so not possible to tip with SBD, but that should be fine, or? You could consider to put @ sign in front of recipient, this is what Steemit user are accustomed to, but not sure if that works for your application. Ohw, also note the . and , are in USA different to eg Europe. Not sure if possible, but if both can be accepted as the same ie 0.1 = 0,1 would cause maybe some less errors.

In text messaging and especially USSD (not sure of you know that from your mobile) they usually use some extra markers in from of the text message to identify it is a command. It will complicate things a bit, but may also become more recognisable as a command rather than a comment. Characters like # * are used, but I guess this may be not wise with Steemit's markdown editor and different meaning to those symbols.
