What is a Mint?

A mint is a public evidence record for any item.

Cards, comics, records, magazines, memorabilia, and household valuables can be minted. A signature is optional. The badge tells buyers which evidence layer exists and what it does not prove. For trading cards, an Open Card Passport makes those facts usable by outside games.

Minted

Self documented

Proves

HaloVault sealed the item's photo-first record with camera evidence, available EXIF facts, a tamper-evident HaloCert hash, and an RFC 3161 timestamp when available.

Does not prove

Third-party authenticity, grade, market value, ownership, custody, or an autograph.

Store-Verified

Shop attested

Proves

A HaloVault authorized verifier physically inspected and identified the item, photographed condition at verification time, and attached a store attestation. NFC is optional.

Does not prove

A grade, appraisal, financial guarantee, ownership guarantee, or signer/autograph certification.

Signed & Minted

Signing layer

Proves

HaloVault sealed a signing association that links the minted item to a signed companion card and timestamped signer video evidence.

Does not prove

The original item itself was autographed unless separately stated. It is not a grade, appraisal, or financial guarantee.

For trading cards · Open Card Passports

Mint the physical card once. Verify it anywhere.

A card mint automatically receives one stable HV-CARD-… Passport. Any TCG or tournament platform can read its mint and authentication facts through HaloVault’s free API without HaloVault hosting the game.

Physical authenticationA Store-Verified mint says an approved shop physically inspected and identified the card at a recorded time.
Optional blockchain bindingA compatible external token can commit to the Passport. Blockchain state proves token control after a fresh wallet signature—not legal ownership of the physical card.
Optional NFCA physical tag can open or strengthen the in-person record, but the Passport ID and public API are enough for online verification.

Coming to HaloVault · HaloWitness

Mint once. Witness whenever it matters.

A mint preserves the item’s permanent photo-first identity. HaloWitness is the planned fresh layer on top: each successful Witness or ReWitness will append a new point-in-time possession event to that same item and its public HaloCert history without rewriting the original mint.

01 · MintSeal the permanent item identity.
02 · WitnessAdd fresh challenge-matching evidence.
03 · ReWitnessRefresh it for a buyer, store, or shipment.
