In blockchain-based applications, keeping an immutable record of transactions is crucial for transparency and accountability. An On-Chain Receipt Generator is a smart contract that records and stores
The On-Chain Receipt Generator is a Solidity-based smart contract designed to issue and store transaction receipts directly on the blockchain. It enables a decentralized and immutable way to track transactions without relying on external databases or third-party services.
This contract does not use imports or constructors, ensuring simplicity and broad compatibility. It also does not require input fields, meaning users simply send Ether to the contract, which then automatically logs the sender’s address, transaction amount, and timestamp.
Receipts are stored on-chain in an array, allowing users to retrieve past transactions by index. An event is emitted for each transaction, making it easy to track and verify activity. This system enhances transparency, security, and trust in financial interactions on the blockchain.
This solution is ideal for applications that require tamper-proof transaction records, such as payment tracking, decentralized marketplaces, or blockchain accounting systems.
