What is Payment Receipt?
A payment receipt in crypto is the on-chain transaction record that serves as proof of payment — including sender, recipient, amount, timestamp, and transaction hash, permanently recorded on the blockchain.
WHY IT MATTERS
Every blockchain transaction is its own receipt — permanently recorded, publicly verifiable, and immutable. The transaction hash serves as the unique identifier, and anyone can look up the full details on a block explorer.
This is fundamentally different from traditional receipts: no paper, no PDF, no lost emails. The blockchain itself is the receipt book, and it can't be altered after the fact.
For accounting and compliance, on-chain receipts provide: perfect audit trail, timestamp proof, amount verification, and cross-referencing capability. The challenge is linking on-chain transactions to off-chain context (what was the payment for?).
