The problem

The digital collectible market is thick with counterfeits, copied artwork listed as originals, contracts with hidden transfer restrictions, fake trading volume created to manufacture the appearance of demand, and collections whose creators have disappeared.

Buyers have no practical way to check any of it, and losses are routine.

Who this is for

Buyers and holders of digital collectibles and tokenised assets, plus the marketplaces and custodians who need to screen listings and reduce fraud losses.

Provenance Check — revenue leak
· Leaking $241,920 a year
· 600 visitors/mo at 1.4% vs 2.8% median
· CAC $245.71 now, $122.86 achievable

Run it yourself: https://nftgem.xyz

Method: leak = (visitors x median rate x order value) − (visitors x your rate x order value). The median is the middle of the category, not the top, so this is a conservative floor rather than a best case. Your inputs never leave this page.

What you actually get

Six things that are true on the first day, not on the roadmap.

  • 01

    Set it up in minutes

    Connect your data once. Provenance Check starts producing answers on the first run, not after a six-week onboarding.

  • 02

    Everything in one view

    The numbers that matter to buyers and holders of digital collectibles and tokenised assets, plus… on a single screen, updated live, with no spreadsheet in the loop.

  • 03

    Alerts that mean something

    Thresholds you set yourself. Provenance Check tells you when a number crosses the line and stays quiet when it does not.

  • 04

    History you can trust

    Every change is versioned and timestamped, so you can answer what happened and when without guessing.

  • 05

    Exports and API

    CSV, scheduled email and a documented REST API. Your data leaves as easily as it arrives.

  • 06

    Roles and audit

    Invite the team, scope what each person sees, and keep an audit trail of who changed what.
