Certification scope

What we certify

We certify evidence-backed facts about regulated payments — not marketing claims. Designed for Digital Euro pilots and equivalent programmable payment schemes.

Scope

Defined scope & exclusions

Every PayProof certificate explicitly states what is included and what is excluded. This clarity is what makes it defendable in audits, inspections, and disputes.

  • Program definition (grant, voucher, subsidy, conditional spend)
  • Rule-set summary (eligible categories, caps, deadlines, suppliers)
  • Programmable constraints when applicable
  • What evidence is considered valid
  • What is out-of-scope (and why)
Evidence

Proportional evidence trail

Evidence requirements are proportional: sufficient to validate declared rules and outcomes, without turning the process into a heavy forensic audit.

  • Invoices, receipts or supplier documentation (as applicable)
  • Rule mapping: how each expense matches a permitted category
  • Confirmation of time constraints and spend conditions
  • Optional sampling strategy for high-volume programs
Responsibility

Responsible party identified

The certificate identifies who declares the facts and who is responsible for the process. This supports accountability and reduces liability ambiguity in regulated environments.

  • Applicant or beneficiary identity
  • Responsible person with role or title
  • Submission date and certificate issue date
Integrity

Verifiable integrity anchor (hash)

A verifiable identifier ensures the certificate cannot be silently altered after issuance, reducing disputes about which version is valid.

  • Document hash
  • Public verification reference
  • Integrity anchoring may be implemented on-chain or via equivalent immutable registries, depending on the program requirements

What we do certify

  • Declared rule-set and constraints of the regulated payment program
  • Existence of evidence proportional to the case
  • Mapping of expenses to allowed categories (within scope)
  • Identification of the responsible party
  • Integrity anchor and public verification reference

What we do not certify

  • Absolute absence of fraud, error or residual risk
  • Full legal compliance across all applicable regulations
  • Future outcomes, guarantees or performance ratings
  • Information not provided or not declared as evidence
