Joined by brilliant hackers, prestigious guests, mentors, judges and leading projects in the Polkadot community, the 2-day DoraHacks Substrate Hackathon was successfully held in Hangzhou. 70+ Hackers and more than 100+ audience participated in the event. 11 teams working on Defi, NFT, DAO, Oracle, Wallets and other topics launched their projects on Hackerlink.io/buidl, sharing the total prize pool of $15000+ sponsored by Polkadot Treasury and Huobi Polka Eco Fund.

The hackathon was actually the final competition event after a series of online workshops about Substrate and Kusama&Polkadot on both technical details and how to contribute or participate in the ecosystem.
