This was one of the first apps I shipped for Hive this year. HiveScratch is what it is, lottery tickets on the blockchain. You buy a ticket and you instantly win or lose.
This was the test of my Hive stream library which allows building Hive apps easy peasy. I've given it a bit of love and redesigned it. Functionally the same, but visually very different.
I might refine it a little more, but aesthetics matter. I also cleaned up some of the underlying aspects of the smart contract for handling the lotteries. It's using similar code that is available in the Hive Stream repository too.
You can check it out here HiveScratch.
