  • Event Ticketing Platform - EAS (Awarded)**

    This project, developed as part of the BCAMP Apprenticeship Bootcamp, serves as a functional MVP for an Event Ticketing Platform built on the Ethereum Attestation Service. Alongside the project, there's an additional link to the bootcamp's final presentation and a demo video. Note: The demo video might appear outdated as some features were finalized post the program's conclusion.

    Key Technologies:

    1. Ethereum Attestation Service - Delegated Attestations: The attestation is a structured and signed piece of data and it was used to emulate a ticket (attested from the event organizer to the end user). The EAS SDK was utilized for creating an attestation schema and making delegated attestations.
    2. Smart Contracts Development: Used to write a resolver contract (triggered by the attestation) that aims to create collectible NFTs and send them to the user, enhancing engagement and preserving them as memories.
    3. Frontend Development with Next.js and Tailwind: Utilized for a clean and user-friendly interface.
