### Integration Approach: Applying Token Engineering within OP

**Radio SpaghettETH's Token Engineering Integration within Optimism (OP)**

Radio SpaghettETH utilizes a token engineering framework to integrate within the Optimism ecosystem, leveraging the benefits of ETH technology to create a decentralized and self-sustaining community radio platform. Here’s how we apply token engineering in our project:

1. ** ZuPass OR SpaghettETH Passport SBT (Soulbound Token):**
   - **Role and Function:** The SpaghettETH Passport SBT is a free, non-transferable token that acts as a key to unlock various functionalities within our platform. It ensures that only verified community members can curate content, book on-air slots, and participate in governance.
   - **Access and Curation:** By being a verified ZuPass holder or holding a Passport SBT, users gain the ability to curate the radio's content, maintaining the quality and relevance of broadcasts while fostering a sense of ownership and responsibility among community members.

2. **On-Chain Calendar and Slot Booking:**
   - **Smart Contracts:** We utilize smart contracts on the Optimism blockchain to manage an on-chain calendar where ZP verified OR SBT holders can book their broadcasting slots. This ensures transparency, immutability, and trust in the booking process.
   - **Dynamic Player Integration:** Every block.timestamp, the Dynamic Player fetches a different livestream URL from the RadioCalendar.sol contract, providing a seamless and automated listening experience.

3. **Sponsor-Bidding System:**
   - **Monetization Mechanism:** Our sponsor-bidding system allows brands to bid for calendar slots, providing curators with opportunities to earn from their content. This system is managed by smart contracts, ensuring fair and transparent bidding processes.
   - **Revenue Sharing:** A portion of the sponsorship fees (up to 7%) may be allocated to support platform maintenance, debugging, and community outreach, ensuring the platform's sustainability and continuous improvement.
