Vire Protocol

Vire Protocol (French for "transfer" bc why not xD) is a decentralized tuition payment protocol that leverages blockchain technology to make tuition payments in stablecoins (USDC and USDT) more accessible for international students and universities. Vire Protocol streamlines the payment process by directly minting a unique NFT card for each student, which belongs to the university’s unique mint collection. The protocol automatically freezes (stakes) the NFT at the start of each semester and allows students to unfreeze (unstake) it once the semester ends.

Overview

Vire Protocol is designed to address the cumbersome and expensive process of making international tuition payments. By utilizing stablecoins and NFTs on a blockchain network (such as Solana using the Anchor framework), the protocol minimizes intermediaries, reduces fees, and introduces a transparent, secure method for verifying tuition payments.

Workflow

1. Student Payment:
   A student pays the tuition fee directly to the university using stablecoins (USDC or USDT).

2. NFT Card Minting & Freezing:

   • Upon successful payment, the protocol mints a unique semester card (NFT) for the student.
   • This NFT belongs to the university’s unique mint collection.
   • Immediately after minting, the protocol automatically freezes (stakes) the NFT in the student’s wallet for the duration of the semester.

3. Semester End & Unfreezing:

   • At the end of the semester, the student can unfreeze (unstake) their NFT card, signifying the completion of that semester's tuition payment cycle.
