Put promises on the blockchain


People shake hands all the time, but we're not very good at it. Think flaky friends, clients, and deals that fall through.. here's a better way to shake!

Handshake is an app that transcribes commitment into code, and immortalizes promises on the blockchain. This creates an eternal, unchangeable record of intent - without fear of forgery or fraud.

    It's a unique concept


    Not sure who it's made for

    I can see myself using this among tech friends for fun. IF they add more functions like attaching outside documents, it could be a lot more than that, maybe actually useful in business.

    Generates test ether for you without you having to leave the app


    Convincing my non techy colleagues to join was difficult

    Easy to read even on small iphone 5 screen

    Clever idea! cool interface and lots of potential for humour!


    could be a bit limited..

    Great app for more informal situations, but could be much more! Would be amazing if real payment options were added!
