Consider yourself a Blockchain expert?  Still trying to figure out how it works?  Join our CTF competition to test your skills, see how you stack up, and win some great prizes!



Blockchain CTF (  is a Decentralized App (DApp) containing vulnerable smart contracts with various business use cases ranging from decentralized trust funds and open source lottery systems, to ICOs and automated royalty agreements. Players are challenged to exploit vulnerabilities that are commonly found in smart contracts to steal fake testnet ETH and earn points. Hints are available when creativity is exhausted.

At the beginning of the competition, two new challenges will be added to our existing 11 challenges. The first participants who can successfully exploit these new smart contracts alongside the existing ones will be rewarded with prizes.


  • Starts: Friday, March 1 at 8:00 p.m. EST
  • Ends: Monday March 11 at 3:00 p.m. EST


Winners will be announced Monday night at 6:00 p.m. EST

  • 1st place: the first player to solve all 13 challenges (15,000 points) wins $300 DAI
  • 1st – 5th place: The next four to solve all 13 challenges will win $50 DAI each
  • Bonus winners: two random contestants will be awarded $50 DAI each just for signing up (using our moderators for centralized randomness and querying the smart contract for proof-of-participation).
