Ethereum Push Notification Service (EPNS) emerged from the Indian startup scene in 2020. It's a decentralized notification protocol that enables DApps to send push notifications to Ethereum wallet users. EPNS also provides incentives to users that opt-in for push notifications, creating the possibility for an ecosystem communities around topic-centric channels. We are joined by Harsh Rajat, Project Lead and Co-founder of EPNS.

During the DeFi Summer of 2020, YAM Finance launched with a bang, and had its share of ups and downs within its first couple of days. It started out as an experiment to bring together some of the more innovative ideas in the space. It sparked a movement which brought massive attention to yield farming, and started the food token craze. After a bug was discovered in the v1 contract, many thought the project was dead. But no, the team and community have been working diligently to bring the protocol back to life and it's now a community-run DAO innovating at the intersection of decentralized governance and programmable finance. Trent Elmore is one of the creators of YAM. He joins us to talk about the incredibly swift birth of the project, the rebase mechanism, the treasury, the infamous bug and how they saved the project. He also shares some of the new upcoming products on the YAM Roadmap, and how a truly decentralized community is rebuilding its brand.
