Origin verified. Custody appended.
For assets with long timelines, use a file that verifies itself.
AssetSeal issues a single provenance record for an asset’s origin, then records custody as append-only events — without rewriting the origin seal.
Where AssetSeal fits
One surface to verify. Three levels of depth.
A portable file that stays intact. Anyone can verify it. No account required.
Seal origin once, then append custody events. The first seal never changes — the record only grows.
For teams: operational automation, API sealing, webhooks, and volume workflows around sealed proof files. WireProof is one included automation in this tier.
Collector checklist
When you’re acquiring an asset
Screenshots fail. Originals verify.
Drop it into Verify. You get a deterministic verdict — online or offline.
Origin is sealed once. Custody is append-only. Missing links are visible by design.
Seal the origin
Create the source-of-truth record the moment the asset enters custody. That first seal becomes the reference.
- • Photos + identifying marks (serials, inscriptions, grading refs)
- • Optional attachments (certs, invoices, appraisals)
- • Verifier link + QR for checking
Append custody events
Custody doesn’t edit history. Each handoff is recorded as a new event — auditable over time.
- • Sale, consignment, loan, vault intake, insurance events
- • Optional co-sign (gallery, appraiser, vault, insurer)
- • Clear progression: origin → custody → current custodian
One file. One verdict.
Verify independently.The file verifies itself.
- • Cryptographic integrity check (tamper = fail)
- • Custody validation (missing link = flagged)
- • Offline verification supported
Paper you can’t trust
Counterfeits thrive on editable documents and unverifiable provenance. AssetSeal replaces “trust me” with a file that verifies itself.
- • Altered PDFs / swapped photos / reprinted certificates
- • “Same docs, different item” listings
- • Retroactive edits and missing custody links
A clean public surface
Verification stays public. When you need more detail, you can attach deeper evidence without changing the public truth.
- • A shareable verifier link + QR
- • Optional attachments for audits and disputes
- • Exportable records for vaults, insurers, and collectors
Keep provenance intact across resale, storage, and inheritance.
Issue origin + custody in a form collectors can verify independently.
Public verification + append-only custody + exportable audits.
