The culmination of the web3 incubation program will be held on June 18th at a live in-person venue as well as online in the COSMIZE Metaverse, and will feature pitch sessions from each project to showcase their innovations to venture capitalists and corporations interested in collaborating with web3 startups.

The event will be an opportunity for those who want to learn about practical uses of web3 through hands-on experience and presentations from cutting-edge global projects, and for those who want to gain a deeper understanding of the web3 vision that Astar Network and Sony Network Communications are working on.

There will also be opportunities to interact directly with the program candidates, both online and offline.

With that being said, we are delighted to highlight the last four of nineteen exceptional candidates being recognized for their innovative approaches to revolutionize various aspects of the web3 ecosystem.
