Unipay-Card Solana

This repository contains the Solana implementation of the Unipay Card smart contract. The contract enables users to collateralize SOL to obtain a credit limit, allowing them to open a virtual credit card and add credit for real-world spending.

Overview

Unipay Card on Solana provides a decentralized solution for users to leverage their SOL holdings to access credit. By staking SOL, users can:

• Obtain an Initial Credit Limit: Collateralize your SOL to receive a starting credit line.
• Open a Virtual Credit Card: Use your credit line to open a Unipay virtual credit card for everyday purchases.
• Improve Credit Score: Enhance your creditworthiness through timely repayments and honest on-chain activity.
• Access Unsecured Lending: Eventually unlock unsecured borrowing limits without needing additional collateral.

Features

• Collateralized Lending: Stake your SOL to receive a credit limit on your Unipay virtual credit card.
• Progressive Unsecured Lending: Increase your credit score to access unsecured credit lines over time.
• Credit Scoring System: Our algorithm evaluates your on-chain behavior to adjust your credit limit.
• Real-World Spending: Bridge the gap between crypto assets and everyday expenses with seamless integration.

Usage

• Collateralize SOL

  Stake your SOL through the contract to receive an initial credit limit.

• Manage Your Credit

  Monitor your credit limit and repayment schedule via the Unipay dashboard.

• Improve Your Credit Score

  • Timely Repayments: Make payments on time to boost your credit score.
  • Honest On-Chain Behavior: Maintain compliant and trustworthy interactions on the blockchain.

• Unlock Unsecured Credit

  As your credit score increases, gain access to credit without additional collateral.

Credit Scoring System

Our credit scoring algorithm considers various factors:

• On-Chain Activity: Interaction with mainstream protocols and absence of fraudulent behavior.
• ENS Participation: Engagement with the Ethereum Name Service.
• Repayment History: Track record of timely repayments on your Unipay Card.

This system ensures that only trustworthy users gain higher credit limits and access to unsecured lending.
