NEAR Redpackets, based on NEAR Linkdrop.
The app allows you to give people NEAR accounts that are prefunded with NEAR tokens. This is better than just a vanilla Linkdrop because it allows you to queue up multiple of them and it has a nice UI for the recipient.
The app does this by sending funds to the Linkdrop contract which will create "Drops". You will have a list of these in local storage and you can remove them at any time. This claims the funds back to your current account.
