Turn the JSON you already produce into verifiable execution evidence.
NexArt Evidence Bridge applies a published deterministic mapping profile to your application's existing JSON, creates and locally verifies structured NexArt execution evidence, and can optionally submit the unchanged evidence for separate NexArt Node attestation.
CURRENT SCOPEYour JSON

No fabricated CERs.

No fabricated CERs.
Trust boundary Bridge verifies the integrity of the transformation and preserves mapping provenance. It does not independently prove the truth or completeness of the source event.

MAPPING PROFILES / CREATE
Define a truthful transformation.
Published revisions are immutable. Changes create a new revision linked to its exact profile hash.

01 / SOURCE FORMAT
Choose the JSON source.
The source preset controls only deterministic Auto-map aliases. It does not change the evidence type or runtime endpoint.
02 / EVIDENCE TYPE
Choose the evidence you want to create.
Choose the kind of execution evidence you want to create. Auto-map uses this target to suggest how fields in your existing JSON correspond to NexArt evidence semantics.

MAPPING PROFILES / PREVIEW
Review the public mapped representation and evidence check.
Mapping and evidence outcomes remain separate. No single badge represents the entire trust state.
Trust boundary Bridge verifies the integrity of the transformation and preserves mapping provenance. It does not independently prove the truth or completeness of the source event.
Run a preview from the mapping screen first.
PUBLIC MAPPED REPRESENTATION
Confidentiality-safe mapped view
Protected values are hidden here after confidential evidence is created. Their mappings remain visible in Origin Trace, while the CER contains cryptographic commitments for those fields.
Public representation derived from BridgeMappedEvent—
ORIGIN TRACE
Where each field came from
Origin Trace shows where each evidence field came from in the source JSON. Protected values may not appear in the public mapped representation after confidential sealing.

EVIDENCE STATUS
Independent status signals
Each signal answers a separate question. No single status represents the complete trust state.
Preview CERGenerated locally from this representative sample for review. It is not stored as a production transformation result and has not been Node-attested unless explicitly shown otherwise.
Mapping validThe configured transformation completed successfully.
Evidence eligibleThe mapped event contains the semantics required by the selected evidence target.
Preview CER createdA local preview evidence artifact was generated.
Locally verifiedThe generated evidence passed its corresponding local integrity verification.
Node attestedA separate NexArt Node attestation exists.
Independent timestampExternal timestamp evidence has been independently verified where applicable.

Transformation results.
Compact by design. Select a result to inspect source integrity, mapping, and evidence.
RESULT ID / SOURCESTATUS
Results appear after a profile receives native JSON.
Select a result to inspect its evidence record.
INTEGRATION
Send the JSON you already produce.
The mapping profile performs the deterministic transformation at the current host. No manual CER creation is required.
POST
/api/v1/ingest/—/—Send the same native JSON your system already produces. Responses include independent mapping, eligibility, and verification fields.
