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, manual exchange-rate lookups, spreadsheets or retroactive reconciliation.
