How it works

Four steps, the same ones you'll see in your dashboard.

  1. 1

    Apply

    Business details, documents and agreement to the platform rules.

  2. 2

    Approved

    Our team reviews your store and documents.

  3. 3

    Connect Stripe

    Your own Stripe account, described accurately.

  4. 4

    Live

    Install the plugin or embed script and sell to verified buyers.

Verification

Buyers prove an institutional email, credentials and an EIN or license before they can reach checkout. You approve each one.

Attestation

Every order carries a signed intended-use attestation, hash-chained per merchant and exportable as an evidence packet.

Monitoring

Your storefront is scanned daily for human-use claims and missing disclaimers, with a 72-hour cure window before anything pauses.

Simple pricing

One plan. Your Stripe account. No funds held by us.
