About PayNotes
PayNotes are programmable payment agreements that create verifiable commitments between payers, payees, and guarantors. They bring transparency, automation, and conditional logic to financial transactions—whether you're a bank enabling account-to-account transfers, a processor preventing chargebacks, or a marketplace splitting payouts across multiple sellers.
Originating from MyOS, this site focuses solely on PayNotes for financial institutions and fintechs integrating conditional payment workflows into existing rails.
