PayNotes

Payments shouldn’t be an afterthought—they should act. With Blue, you can embed logic directly into value movements: conditional pay, refunds, capture/authorization flows, and more—all autonomously executed and auditable.

Traditional payment systems were built for human-paced transactions, where rules live separate from the money itself—scattered across emails, PDFs, and brittle application code. This disconnect creates friction, disputes, and holds back the true potential of automated commerce. PayNotes collapse that gap.


PayNotes are programmable payment agreements. 


They are shared, auditable contracts that precisely tie when money should move to what verifiable events really happened. Designed for regulated providers (banks, processors, fintechs) and modern platforms, PayNotes enable conditional capture, conditional payouts, and evidence-driven releases without replacing your existing payment rails.


The Three-Party Agreement for Trust


Every PayNote forms a transparent agreement among:


  • Payer: Knows precisely what they’ll pay and when.
  • Payee: Clearly understands what to deliver or achieve to get paid.
  • Guarantor: A trusted entity (like your bank, processor, or platform) that enforces the rules exactly, ensuring the agreement’s integrity.


Built on the open Blue protocol, PayNotes provide all parties with the same auditable view of rules and state. They don’t introduce a new settlement layer; instead, they add a powerful logic layer around existing ACH, SEPA, SWIFT, RTP, or card rails, governing authorization, reserving, and release.


Key Benefits of PayNotes



  • Eliminate Disputes: Transparency ensures all parties agree on the rules and evidence, dramatically reducing chargebacks (e.g., in conditional card capture).
  • Evidence-Based Automation: Payment releases are tied directly to verifiable events—shipment delivered, service completed, KYC passed—reducing manual operations and errors.
  • AI-Ready Transactions: Agents can operate within rigid, auditable financial guardrails, making autonomous transactions safe and trustworthy.
  • No Forklift Upgrades: Integrate conditional payment logic with your current payment infrastructure.
  • Open & Portable: Built on the Blue protocol, offering flexibility and avoiding vendor lock-in.
