Challenge Requirements:

  • Projects must use the Covalent API to interact with the on-chain data on Klaytn Blockchain (mainnet, testnet, local Klaytn nodes, service chain, etc.)
  • Projects must adopt Klaytn’s token standards when building the smart contract of their use cases and such smart contracts should be deployed to the Klaytn Blockchain

Submission Requirements:

  • Participants from everywhere can participate in this bounty
  • You can submit individually, or as a team. Teams should include no more than four people.

What makes a submission complete:

  • A presentation (PDF, Slidedeck etc) describing the project
  • Link to a video demo (YouTube only) is advisable, but not strictly required
  • You project live/demo site must be web hosted and publicly accessible
  • Your project code repo must be publicly accessible
  • The submission must be released under a GPLv3 compatible license

Judging Criteria:

  • Submissions will be judged by Covalent based on their technical merits as well as the likelihood of implementation.

In general, submissions are graded on a 1-5 scale in each of the following categories

  • Originality - Does the template incorporate something entirely novel, or at least take a fresh approach to an existing problem?
  • Execution - Is the template usable in its current state? Is the user experience smooth? Does everything appear to work? Is it well designed?
  • Usefulness - Is the idea practical? Is it something people would actually use?
  • Learning - Did the individual or team stretch themselves and push the boundaries of learning in this space?

While all projects are technically eligible for the pool prize, Klaytn and Covalent judges will have the final say on which projects qualify.
