Payment Application Using Crypto Currencies

Abstract

In the rapidly evolving world of digital finance,there remains a growing need to bridge the gapbetween decentralized crypto assets and traditionalfiat currency systems. RupXpay is a robust andsecure payment application designed to meet thisdemand by enabling users to convert their cryptocurrency into Indian Rupees (INR) and alsoperform direct INR transfers through their bankaccounts. The app begins by allowing users toconnect any Web3 wallet of their choice (such asMeta Mask, Trust Wallet, etc.). Upon successfulconnection, RupXpay displays the user’s real-timewallet balance, providing full visibility andtransparency. When a user wants to convert theircrypto holdings into INR, they simply enter thedesired amount, select the block chain network,choose the crypto currency, and the preferredpayment method. To initiate the transaction, theuser must provide a digital wallet signature, whichnot only authorizes the transaction but alsotriggers a temporary wallet lock for five minutes.This lock mechanism ensures the transaction dataremains secure and unaltered during theverification process, significantly reducing the riskof fraud. The system calculates applicable gas feesbased on the selected network and applies a fixed1% fee for network processing and a 2% service feecharged by RupXpay for conversion services. Onceverified, the INR amount is credited to the user’slinked bank account. In addition to crypto-basedconversions, RupXpay supports traditional bankto-bank INR transfers. By linking their bankaccount within the app, users can send moneydirectly to other users without involving cryptocurrency, making RupXpay a complete, dual-modepayment solution. By combiningblock chain technology with traditional financialinfrastructure, RupXpay provides users with areliable, efficient, and secure platform to makecrypto spendable in everyday life. It is a futurereadyfinancial tool that redefines how digitalassets are used in the real economy.
