## About

Invoice in fiat, accept crypto payments, and generate tamper-evident, verifiable receipts. OnchainInvoice produces cryptographically signed documentation—PDFs, canonical payloads, and proof files—that can be independently inspected. Built as documentation infrastructure between invoicing and on-chain settlement, without custody or post-hoc reconstruction.

Designed for individuals and small teams who accept crypto payments but still need clean, defensible fiat accounting.
