Abstract
Payvol is an open, wallet-neutral coordination layer for programmable payments on Canton. It standardizes how a payment intent is expressed, safely presented to a payer, translated into an authorized Canton Token Standard transaction, and reconciled through a private lifecycle after submission, so that an intent can travel through a QR code, URI, NFC record, web link, API, invoice, message, or an application-to-wallet handoff without binding the payee to a specific wallet, custodian, token issuer, or settlement application. The grant turns the existing self-funded prototype into a stable public standard, a production TypeScript implementation, a conformance suite, Canton execution profiles, a lifecycle and reconciliation toolkit, a self-hostable resolver, an ISO 20022 Request-to-Pay reference converter prototype, and a version-pinned x402 representation mapping. Every deliverable is an open-source, reusable component or standard designed to support multiple Canton applications, wallets and issuers rather than one-off, application-specific integration work.
