Baby Blocks

Want to host a lottery with your friends or family, but don’t want to hassle everyone to pay their due? Baby Blocks is a web app allowing users to play a lottery to guess a baby’s arrival date, and is managed by a smart contract on the Ethereum blockchain.

Micaela O’Herron created this app using Javascript and React on the front end, a smart contract built with Solidity, and Metamask to enable transfer of ether between players.

To enter this lottery, launch your Metamask account on the Rinkeby test network and check out the repo at!
