KeepReceipt: Mint Receipt NFTs

KeepReceipt overcomes the limitations of traditional paper receipt storage or image storage methods by providing a fully on-chain digital receipt management service utilizing blockchain technology. All core receipt information and verification data are recorded directly on the blockchain network, without the use of off-chain storage or IPFS, ensuring tamper-proof, permanently verifiable storage. Issued receipts are provided as digital assets in the form of NFTs, allowing users to directly retain ownership of their receipts and transfer or assign them as needed. This allows receipts to go beyond simple storage records and serve as reliable digital proof of transaction. Furthermore, KeepReceipt utilizes Web3-based social login and wallet address authentication, eliminating the need for complex membership registration. It also aims to minimize personal information collection and prioritize user sovereignty. Based on a decentralized blockchain network (including a testnet) that does not rely on a centralized server, KeepReceipt provides a transparent and sustainable receipt management environment where users directly control their data. Ultimately, KeepReceipt aims to become a next-generation digital receipt management service with trust and transparency, extending receipts as digital assets and on-chain proofs.
