Tipping protocol / extension
ProTip is a Bitcoin-tipping browser extension that lets readers send small Bitcoin tips to web-page authors and contributors. Launched in the 2014–2015 era as one of the early "stack sats to support creators" projects, it sits in the same historical family as Tallycoin (Lightning crowdfunding) and XSats.
The project is referenced in the Curio Wiki as part of the broader Bitcoin-tipping-infrastructure history; the on-page tipping model influenced later projects like Brave's BAT and various Lightning Bolt-card experiments.
