Foyer

This project combines blockchain smart contracts and a modern web frontend to create a decentralized secondary marketplace for event tickets. Foyer eliminates fraud and reduces fees in ticket resale by leveraging Ethereum's security The platform is designed to solve critical problems in traditional ticket resale: high platform fees (15-25%), fraud risks, payment delays, and lack of buyer protection. Users connect their Web3 wallets, complete KYC verification, and can then buy or sell tickets with complete transparency and security.

PARTNER TECHNOLOGIES:

1. PayPal USD: We use PyUSD as a reserve currency in our system. We aim to have a safe and secure yield generation mechanism around it one day so that we can offer our protocol services at zero or minimal cost.

2. Self Protocol: We’ve chosen Self Protocol to ensure KYC compliance, build trust with verified buyers and sellers, and maintain fairness through robust dispute resolution.
