Announcing the winners of Klaymakers22, Klaytn’s Flagship Web3 Hackathon


  • Klaymakers22 saw over 23,000 workshop participants and 174 project submissions
  • 19 projects walked away with over $1million in prizes, sponsor bounty challenges, and grant and incubation opportunities

Just last Friday, we crowned the inaugural winners of Klaymakers22, Klaytn’s flagship web3 hackathon! 19 teams walked away with over US$1 million worth in prizes, sponsor bounty challenges, and grant and incubation opportunities.

Klaymakers22, co-organised by DoraHacks, successfully attracted both web3 & web2 developers to buidl use cases on Klaytn with the ease of our EVM-equivalent network. We received a total of 174 amazing submissions with use cases ranging from decentralised art generation to DAO creation and management without the need for prerequisite coding knowledge. Participants also had special access to Klaytn’s developer community on Discord as well as free business and technical workshops which garnered a total attendance count of 22,948.

The first round of judging was conducted by senior representatives from Klaytn and our hackathon partners. 20 finalists were selected and tasked to pitch their buidls via live demo sessions to the judging committee before the 12 winners were determined. Submissions were judged on criteria including originality, execution, and usefulness.

On November 18, 12 winners were announced through a virtual ceremony, and 3 of the hackathon winners, alongside an additional 7 teams, received special mention for winning the bounty challenges.
