HostIt

The Ultimate Event Ticketing & Management Solution on Mantle.

🌟 Introduction

HostIt is a decentralized, comprehensive event management protocol built for the Mantle Global Hackathon 2025. It empowers organizers to create, manage, and sell tickets with ease, while providing attendees with a seamless, secure, and transparent purchasing experience using the power of Mantle Network.

🚀 Key Features & Strengths

For Organizers

• Comprehensive Dashboard: A powerful Next.js-based dashboard to manage events, track sales, and analytics.
• Flexible Ticketing: Create various ticket tiers (VIP, General, Early Bird).
• Modular Smart Contracts: Built using the Diamond Pattern (EIP-2535), ensuring the protocol is fully upgradable and scalable without breaking legacy integration.

For Attendees

• Seamless Onboarding: Integrated with Dynamic for easy wallet connection and social login.
• Low Fees: Powered by Mantle's low gas fees, making ticket purchases affordable.
• Instant Confirmation: Fast block times ensure tickets land in wallets instantly.

🏗 Architecture & Tech Stack

Smart Contracts (Mantle)

• Diamond Pattern (EIP-2535): Allows for unlimited contract size and modular upgrades.
• Solidty 0.8.30: Latest secure practices.
• Foundry: For robust testing and deployment.

Frontend

• Next.js 14: Modern, server-side rendered application.
• Mantle SDK & Wagmi: smooth blockchain interactions.
• Dynamic: Best-in-class authentication.
• TailwindCSS & Shadcn/UI: Beautiful, responsive design.

Backend

• Node.js: For off-chain indexing and metadata handling.

🟢 Integration with Mantle

HostIt leverages the Mantle Network to solve the distinct challenges of on-chain ticketing:

1. Cost Efficiency: Minting thousands of NFT tickets is prohibitively expensive on L1. Mantle's low fees make it viable.
2. Speed: fast finality is crucial for QR code check-in at physical gates.
3. Future Proofing: The Diamond proxy allows us to add new features (like Soulbound Tickets or Dynamic Pricing) to the same address on Mantle.
4. Cross-Layer Payment: Utilizing the Mantle SDK, users can pay for tickets using funds directly from L1 (Ethereum) without bridging first, smoothing the onboarding process.
5. Cross-Chain Bridging: Tickets (NFTs) can be bridged back to L1 or other L2s, giving users true ownership and flexibility.

🤝 Value to the Mantle Ecosystem

HostIt brings a production-ready, real-world utility to Mantle. Unlike speculative DeFi apps, HostIt drives mainstream adoption by onboard non-crypto natives through events. It showcases Mantle's capability to handle high-frequency, low-value transactions (tickets) reliability.
