The 0Chain Hackathon ran from July 2019 to June 2020.
We are not inviting new Hackathon entries now because we would prefer developers to concentrate on our Hacker initiative to help ensure our platform is robust and ready for mainnet.
However if you specialise in integration with other platforms, please get in touch because this area is ongoing and will continue into mainnet.
But please do get in touch first because there may already be someone working on the same integration.
Please see our Telegram Hacker Channel for previous discussions and resources:-
