(Checkbook) Prizes

Checkbook offers one simple API to provide a way for Businesses to send out a payment to anybody with an email address or phone number. The recipient of the payment does not need to sign up or login

According to the stats published by the Federal Reserve 14Billion paper checks and 24Billion ACH payments were made in 2019! Businesses are still using antiquated systems like paper checks and ACH to send payments. Checkbook provides an API for business (and individuals ) to send a payment to anyone with an email or phone number. The recipient does not need to download an app or sign up.
We are looking for creative uses of our API to solve the simple problem of getting payments to anyone. Traditionally all payment systems are two sided i.e. they require both sender and recipient to enroll before being able to make a payment (e.g. paypal, zelle, venmo, squarecash etc. ) We are the only “one-sided” payment system i.e. the recipient does not need to enroll before accepting a payment

Prize: Google minis for each team member

(Matrix) Best Application of Crypto

The best use of crypto in your project wins $500 in ETH

Judging Criteria

  • Creativity
    We want hackers to create a project that makes you say “wow” and tell all your friends about it. We're looking for projects that think so far outside the box that you begin to wonder why there was a box at all in the first place.
  • Technical Complexity
    In only 36 hours, hackers manage to build projects with remarkably complex infrastructures built on excitingly advanced frameworks. We hope to see projects that are really running some beautiful code or hardware under the hood.
  • Social Impact
    We're looking for hacks that seem crazy, the moonshots that seem out of this world, and the blueprints for change that will impact future generations in humanity's most pressing areas of concern in the coming years.
