Verify that QR code payments scan correctly across different UPI apps and banks regardless of which app generated the code. Anchored transaction routing data helps the network operator find and resolve interoperability failures with verifiable evidence of where a transaction broke.
Turn intermittent scan failures and routing errors into anchored, diagnosable evidence.
01.
Record the path. The Audit Logs module anchors verified transaction routing data across participating apps and banks, so each hop of a payment is evidenced.
02.
Confirm the scan. The External Data Oracles module verifies that a QR generated by one app resolves correctly in another, surfacing version mismatches.
03.
Find the break. When a transaction fails, the anchored path shows exactly which app or bank hop broke, replacing guesswork with evidence.
04.
Enforce the spec. The Compliance Attestations module checks each participant's QR handling against the interoperability standard and flags a deviation.
05.
Fix with proof. The network operator resolves an interoperability issue against verifiable evidence rather than conflicting logs from each party.
06.
Attribute the fault. Because each hop is signed, a routing error is attributed to the responsible participant, driving faster fixes.
Follow a single cross-app QR payment from scan through routing to a diagnosed failure and resolution.

Cerulea decomposes interoperability verification into modular contracts. Each layer records a scan, traces routing, localizes failures, and attributes fault without conflicting logs.
Interoperability verification is a horizontal capability. Here is how different actors rely on evidenced routing.
Diagnose and resolve interoperability failures from anchored routing evidence, replacing conflicting participant logs with a single verifiable path.
Key Asset Types
See exactly where a cross-app payment broke and conform to the interoperability standard, reducing scan failures that frustrate users.
Key Asset Types
Attribute routing faults accountably and audit interoperability from verifiable evidence, driving faster fixes across the network.
Key Asset Types
Whether you are bridging a participant's switch or collecting scan data from apps, Cerulea routes both into one evidenced interoperability record.
For participants on legacy switch systems. Routing events are translated into signed on-chain hop records through the API gateway automatically.

The legacy timeline reflects payments network integration benchmarks. Building routing anchoring, cross-app verification, failure localization, and accountable resolution across participants takes a baseline of 7 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your routing and conformance rules into pre-audited WebAssembly binaries and provisions the interoperability ledger and diagnostics layer instantly.
