Tools

Optional services built around DAR and SV-DAR. Receipts are free to exist and verify independently. You pay only when systems are asked to perform work at scale — such as traversal, analysis, aggregation, or reporting.

Verification

Verify receipts

Independently validate receipt integrity, schema compliance, and cryptographic signatures (when present). Supports single-receipt and batch verification without accounts or issuer access.

Chain operations

Traverse timelines

Analyze receipt chains and graphs to detect gaps, ordering conflicts, broken references, and continuity issues. Designed for dispute resolution, audits, and incident review.

Intelligence

Reason & report

Generate summaries, detect anomalies, run policy checks, and export audit-ready evidence packages when accountability and defensibility are required.

Usage-based

Fairness model

Receipts are free to exist, share, and verify. Fees apply only when our systems perform computation — traversal, aggregation, anchoring, analysis, or reporting — never to access or verify truth.

Important: The verifier is a neutral reference tool. Any party may implement a conforming verifier that produces the same results. Digital Action Receipts are designed to remain verifiable even if this site or its operators are unavailable.
