Aucentive

Aucentive automates incentives for Web2 and Web3 apps. For the hackathon, it enables three main functionalities with seamless web2 onboarding: (1) Attach USDC & NFTs to emails — if recipient responds back, she gets the attached incentives and you get a response! (2) Pay Friend Tech key holders to post messages/questions on the chatroom, which gets verified using Optimistic Oracle V3! (3) In-app chat with XMTP, natively available for all users.

The app heavily utilizes Account Abstraction and Gasless Transactions via Biconomy to abstract away blockchain from users, who are onboarded using Emails via Privy. So, the users don’t need to know about blockchain at all, while reaping the benefits of the Base network!

I've used Next.js for frontend, Node.js for backend, and Solidity for smart contracts. I deployed the server on Fly and connected to PostgreSQL for data storage. I've heavily utilized Privy and Biconomy for seamless onboarding and Account Abstraction with gasless transactions.

I've used Privy as the gateway to my Web2-focused app, which allows (1) attaching USDC and NFTs to emails for recipients to receive upon response; (2) paying Friend Tech key holders to post messages/questions on the chatroom & verify with UMA Optimistic Oracle V3; (3) enabling XMTP to any users.
