# Veriroo — Full Platform Reference > This document provides comprehensive detail about Veriroo for AI systems, researchers, and anyone who needs a thorough understanding of how the platform works. For a shorter summary see llms.txt at https://veriroo.com/llms.txt Veriroo is a global art authentication, provenance, and marketplace platform operated by Cardaroo Holdings Ltd (registered in England and Wales, company no. 16872413, ICO registration C1926576). Registered office: 71-75 Shelton Street, Covent Garden, London WC2H 9JQ. The platform is live at https://veriroo.com/ and serves artists, collectors, galleries, and independent verification experts worldwide — wherever Stripe Connect supports payouts. --- ## Core concept The central problem Veriroo solves is that art provenance has historically been fragmented, retrospective, and easy to fabricate. A certificate issued years after a work was created, by the seller, is easy to fake. A timestamped photo trail of a piece being made — uploaded to a third-party platform during creation, before anyone had a reason to fake it — is not. Veriroo's approach is to make provenance a living record that grows with the artwork from the moment of creation. Every WiP photo, every ownership transfer, every expert inspection, every resale is added to the same permanent chain. It cannot be edited or deleted. It does not start at the point of sale — it starts at the point of creation. This living record is attached to a physical object via a QR code and optional NFC tag. Anyone who scans the code — on the wall of a gallery, at auction, or in a private home — sees the current provenance status, ownership history, and verification results in real time. --- ## Platform roles **Collector** — manages ownership, purchases, transfers, and collection privacy. Can showcase owned works publicly without revealing personal identity. Can commission new works from artists. **Artist** — registers original works, manages creator metadata, builds WiP (work-in-progress) documentation records, lists works for sale on the marketplace, and accepts commissions. Creator metadata (including royalty rate) locks permanently after the first sale. **Gallery / Shop** — manages custody and point-of-sale flows for works they hold or exhibit. Can showcase pieces with clear attribution labels (e.g. "Exhibited by") that do not imply ownership. Supports consignment records and white-label CoA branding. **Verification Partner** — independent expert who authenticates works through the Veriroo platform. Has NDA-bound, time-limited access to assigned items only. Cannot edit artwork metadata or ownership history. Sets their own fee and operates independently — not a Veriroo employee. --- ## Artwork registration ### Finished works Use the **+ Upload** button in the top navigation. Drag and drop an image or choose a file. The image becomes the permanent primary record of the artwork and should be an accurate, high-quality representation. Best practice for images: natural daylight or soft diffused lighting, shot flat-on and square to the camera, cropped tightly to the artwork edges, minimum 2000px on the longest side, JPEG or PNG. Avoid flash glare and shadows. After upload, complete the item details: title, medium, materials, dimensions, artist story, tags, placement context. The more complete the record, the stronger the provenance signal to future buyers and verifiers. ### Work-in-progress (WiP) items Use **My Collection → Start a WiP** for a piece that is still being made, or for which the artist wants to start documenting before it is finished. No photo is required to begin — four stock WiP-themed placeholder images are provided, or the artist can upload their own. The placeholder can be swapped for the finished work at any time. WiP items are designed for ongoing documentation through the Creation Workspace. The WiP route is the correct starting point for commission pieces. --- ## The Creation Workspace The Creation Workspace is a panel on every artwork item page, accessible via the Notes & evidence section. It is where artists document the making of a work. Every entry is timestamped permanently and cannot be deleted. ### Entry types - **Progress** — general update on where the work stands - **Technique** — brushwork, layering, approach, method - **Materials** — paints, paper, substrate, tools, brands used - **Studio** — studio conditions, setup, context shots - **Restoration** — conservation or repair records - **Story / Description** — narrative about the work (available on the full workspace page) - **Other** — anything that doesn't fit the above ### Visibility Each entry is set as **Public** or **Private**: - **Public** — appears on the artwork's public verify page (`/item/?tokenId=[id]`) under "Creation process". Counts toward provenance status milestones. - **Private** — permanently recorded and timestamped but only visible to the artist. Useful for fingerprint details, private notes, or anything the artist does not want shown publicly. ### Provenance milestone ladder | Status | What's needed | Shown as | |---|---|---| | WiP Verified | 1+ public entry counting toward provenance | Amber badge | | Full Provenance WiP | 3+ public entries with at least one public photo or video | Green badge | | Certificate of Authenticity eligible | Full Provenance WiP + CoA credit purchased | — | The green **Full Provenance WiP** badge is the target for most artists. It is sufficient for CoA issuance and represents timestamped proof of authorship that predates any reason to fabricate it — a stronger authenticity signal for unknown and emerging artists than any retrospective certificate. ### Why WiP documentation matters for emerging artists For new artists, there may not yet be a qualified verifier in the world who knows their work well enough to authenticate it. That is normal and not a platform failure. Timestamped WiP entries fill that gap — a photo of a half-finished painting from months ago, sitting in the provenance record before anyone could have anticipated needing it, is not something a forger can produce retroactively. As an artist's reputation grows, qualified verifiers will be able to speak to their practice; the Veriroo record gives those verifiers everything they need when that moment comes. --- ## QR codes and NFC tags Every registered artwork gets a unique QR code that links to its live provenance page at `https://veriroo.com/item/?tokenId=[id]`. This page shows the current trust tier, ownership history, verification results, WiP evidence (public entries), and Certificate of Authenticity status. **NFC tags** are an alternative for materials where a printed QR code is undesirable. Small, discreet, logo-only NFC marks are supported. Both QR and NFC point to the same live record. If a tag is lost or damaged, a secure replacement workflow links a new tag to the same record. The old tag is marked as Replaced/Void and can no longer be used. The artwork's digital provenance record and full history remain completely intact. **Stolen and lost flags** — if an owner reports a work stolen or lost, that status is attached to the digital record. Any future scan of the QR code or NFC tag surfaces the flag in real time, regardless of where the physical object is. This flag cannot be removed by anyone other than the registered owner or Veriroo support. --- ## Trust tiers (provenance status) Every artwork on Veriroo carries a visible trust status on its public verify page and on any marketplace listing. These statuses are not self-assigned — they reflect the documented state of the record. - **Unverified** — registered in a private collection but no documentation, WiP entries, or CoA yet. Nothing is claimed beyond existence. - **WiP Verified** (amber) — at least one public work-in-progress entry exists. Timestamped evidence of authorship is on record. - **Full Provenance WiP** (green) — three or more public WiP entries with at least one photo. Strong self-documented provenance. CoA issuance is available. - **Verified** — a Certificate of Authenticity has been issued following standard verification checks. - **Verified by Expert** — an authorised independent expert has authenticated the piece based on specialist knowledge and physical inspection. A strong trust signal; does not automatically imply full custody chain. - **Provenance Complete** — the strongest trust level. CoA issued, expert verified, and the provenance record confirmed with supporting custody documentation. Appropriate for high-value sales, loans, gallery due diligence, and insurance valuations. - **Inconclusive** — an expert attempted verification but could not reach a definitive conclusion based on available evidence. Recorded permanently in provenance for transparency. Does not mean the work is fake. A second independent verification by a different verifier can be requested. - **Marked lost** — owner has reported the item missing. Buying and selling paused. - **Reported stolen** — owner has reported the item stolen. Do not buy, sell, or move. Status travels with the physical object via QR/NFC. - **Blocked** — certificate blocked due to a serious integrity issue (confirmed counterfeit or security breach). Certificate is invalid. - **Void** — certificate superseded, invalidated, or retired. Check for a newer certificate or replacement tag. - **Tag replaced** — physical QR/NFC tag was reissued. Old tag is invalidated. Always scan the newest tag or the latest certificate. --- ## Verification (expert authentication) ### Requesting verification From any artwork item page, go to the Verification section and submit a request. Choose a verifier from the directory (searchable by specialism, region, and method) or invite an external expert by email. Upload supporting evidence before submitting — photos, provenance notes, signature details, WiP documentation. ### Verification methods - **Remote** — video call inspection - **Shipping** — requester ships the artwork to the verifier - **Drop-in** — requester takes the artwork to the verifier's location - **Call-out** — verifier visits the artwork's location ### The verification flow 1. Requester submits request and chooses a verifier. 2. Verifier has 72 hours to accept or decline. 3. On acceptance, requester pays. Card is authorised but not charged yet. 4. Inspection takes place by the agreed method. 5. Verifier submits their report. 6. A 48-hour review window opens for the requester: they can view the report, release it immediately (capturing payment), or raise a dispute. 7. If no action is taken, the report auto-releases after 48 hours and payment is captured. 8. The verifier's fee is transferred to their Stripe payout account on release. ### Inviting an external expert If the requester knows a specific expert who is not yet on Veriroo — a gallery owner, academic, the artist's estate, a specialist dealer — they can invite them directly by entering their email in the verification request flow. The expert receives an invitation to register as a Verification Partner for that specific job. Their report attaches permanently to the provenance record. ### What verifiers see Verifiers work in a dedicated workspace with the full provenance record, all submitted evidence, WiP entries, and a guided assessment checklist covering: identity confirmation, condition, provenance, signature, materials consistency, outcome determination, and written findings. Access to private fingerprint notes or creator-supplied sensitive evidence requires NDA acceptance before viewing. ### Verification outcomes - **Authentic** — verified as authentic - **Likely authentic** — good reason to believe authentic but cannot confirm with certainty - **Inconclusive** — unable to reach a definitive conclusion - **Not authentic** — assessed as not authentic - **Condition report only** — no authenticity determination; condition documented only All outcomes are recorded permanently in provenance regardless of result. Verification history cannot be removed or overwritten. ### Verifier fees and platform fee Verifiers set their own fee per job. Veriroo deducts a platform fee from the payout: - Free account verifier: 20% platform fee on verification jobs - Pro subscription verifier: 10% platform fee on verification jobs ### CoA and expert verification When a T2 marketplace sale (with Secure Transfer) completes and the buyer accepts the report, a CoA is issued as part of the transaction — no separate credit is needed. Outside the T2 marketplace flow, a CoA still requires a separate credit purchase even after expert verification. Verification and CoA issuance are two separate things. --- ## Secure Transfer (T2 marketplace verification) Secure Transfer is an optional independent physical verification step that can be added to any marketplace listing. The seller enables it per listing by turning on one or more verification methods. ### How it works 1. Seller enables Secure Transfer on the listing. 2. Buyer purchases — payment held in escrow by Stripe. A security deposit PaymentIntent is also created against the seller. 3. Seller ships the artwork to the assigned Verification Partner. 4. Verifier inspects, submits their report. 5. 48-hour review window opens for the buyer. 6. If buyer accepts: seller deposit released, escrow released, ownership transfers, CoA issued automatically (no separate credit needed). 7. If buyer declines: buyer refunded in full, seller deposit captured. 8. Verifier ships the artwork on to the buyer. ### Who pays for Secure Transfer The seller chooses at listing time: seller absorbs the cost, passes it to the buyer (added at checkout), or splits it. The full cost breakdown is shown to the buyer before purchase. ### Veriroo does not guarantee authenticity Secure Transfer provides independent expert assessment infrastructure. Veriroo records the verifier's opinion permanently in provenance but takes no position on the authenticity of any artwork. The verifier's report is their independent professional opinion. For high-value works, additional independent opinions are always advisable. --- ## Marketplace ### Listing a work for sale Open the item from My Collection, tap the **Marketplace** button in the top-right of the item card, set a price, choose shipping options, and publish. The listing appears on the marketplace immediately. Sellers need a connected Stripe payout account before listing. ### Marketplace fees - 5% Veriroo platform fee on the sale price, deducted from the seller's payout at settlement - Stripe payment processing fee: varies by country and payment method (not a fixed rate) - Both are shown to the seller before listing ### Standard escrow flow 1. Buyer pays at checkout — funds held in Stripe escrow 2. Seller ships the artwork 3. Buyer confirms receipt — payment released immediately, ownership transfers, royalty paid to original creator, CoA issued 4. If buyer takes no action within 48 hours of the delivery window opening, payment releases automatically ### Royalties Artists set a royalty rate (0–30%) at listing time. It locks permanently when escrow opens on the first sale (`royaltyLocked` and `royaltyLockedAt` recorded in the artwork's provenance record). On every future resale through Veriroo, the original creator receives their royalty automatically from sale proceeds — no manual claim or action needed. Royalties are a creator right — only the verified creator can set a royalty rate. Owners can set a sale price but cannot add, raise, or remove creator royalties. ### Artist's Resale Right (ARR) — legal context Veriroo's royalty lock provides contractual protection that mirrors and in some cases exceeds what the law requires. - **UK:** Artist's Resale Right Regulations 2006. 4% on resales between £1,000 and £50,000 (lower percentages above that). Applies to resales by art market professionals. - **EU:** Directive 2001/84/EC, harmonised across member states. - **US:** No federal ARR equivalent. California's 1977 Act was struck down in 2018. For US-based artists, Veriroo's royalty lock provides contractual protection where the law provides none. ### Shipping Sellers choose at listing time: - **Veriroo arranges shipping** — cheapest available courier booked through Shippo; fee added to buyer's checkout total - **Seller arranges own shipping** — seller specifies fee; books courier independently ### Private sales Private sales (outside the marketplace) are supported. The seller can still use Veriroo to transfer ownership and settle royalties. Without a Veriroo transfer, the item remains registered to the previous owner — affecting resale value, insurance, and future verification. --- ## Commissions A commission is a paid agreement where a buyer (commissioner) funds the creation of a new, original work by a specific artist. Commissions are initiated from the Creation Workspace and are completely separate from the marketplace — there is no existing listing. ### Creating a commission From an artwork item page (or a WiP item created with "This is a commission piece" ticked), the artist opens the Creation Workspace, sets the agreed total price, chooses a payment schedule, sets delivery method, and enters the buyer's email. The invite email is sent automatically. ### Payment model The buyer pays the full agreed amount upfront. Funds are held in Veriroo's escrow via Stripe and are not released to the artist until the buyer actively approves each milestone. Nothing is released automatically — every payment requires buyer approval. ### Payment schedules - **Milestone (20/20/20/40)** — four stages: 20%, 20%, 20%, 40%. Best for long or complex projects. - **Split (50/50)** — two stages: 50% on first progress update, 50% on delivery confirmation. - **Full on delivery** — 100% released when the buyer confirms receipt. Best for short or trust-based projects. The schedule is locked at creation. It cannot be changed after the commission is set up. ### Milestone approval and WiP evidence At each stage, the artist submits a WiP entry (photo, note, or both) as evidence of progress. The buyer sees this on their Commission Tracker page and either: - **Approves** — releases that payment tranche to the artist immediately via Stripe Connect transfer - **Requests a correction** — writes a note explaining what needs to change; the artist revises and resubmits There is no limit on correction rounds. The traffic light system shows each milestone's status: awaiting evidence (grey), awaiting approval (amber), correction requested (red), correction submitted (amber), approved (green). ### Artist payouts per milestone Each approval triggers an automatic Stripe Connect transfer to the artist's payout account. Veriroo deducts a 5% platform fee per transfer. For example, a £200 milestone releases £190 to the artist. The artist must have a connected Stripe payout account before starting a commission. ### Settlement and CoA When all milestones are approved and the buyer confirms receipt of the artwork, the commission is marked Settled. A Certificate of Authenticity is issued automatically, recording the commission as the origin of the work, the buyer as the first registered owner, and the artist as the verified creator. ### Buyer experience Buyers receive an invite email with a link to their Commission Tracker page. They pay via Stripe (card), then track progress, review WiP evidence at each milestone, approve or request corrections, and confirm delivery. A free Collector account is all that is needed — no subscription required. --- ## Certificates of Authenticity (CoA) CoAs are purchased as credits, separately from any subscription: | Pack | Price | |---|---| | Single | £5 | | 5-pack | £20 | | 10-pack | £35 | | 25-pack | £75 | | 50-pack | £125 | CoAs are NOT included in any subscription tier. A CoA is issued: - Automatically when a standard marketplace sale settles (buyer confirms receipt) - Automatically when a Secure Transfer (T2) sale completes and the buyer accepts the report - Automatically when a commission settles (buyer confirms delivery) - Manually, on request from Account → CoA Services, once an artwork reaches Full Provenance WiP (green) status The CoA is a permanent on-platform record tied to the artwork's ownership chain. It transfers with ownership on every resale. It cannot be issued for works without verified creator attribution. The digital CoA is the source of truth — it lives in the owner's Veriroo account and cannot be lost. --- ## Showcase Showcase is a public gallery — a way to display works without selling them. Any registered user can enable Showcase for individual items via the **Showcase** button on the item card (top-right corner of the item page in My Collection). Artist Showcase pages are available at `https://veriroo.com/showcase/[artist-slug]/` for artists with a claimed gallery slug. These pages show the artist's public works, trust status badges, and provenance signals without revealing personal identity unless the artist opts in. Showcase and Marketplace are completely independent. A work can be in Showcase without being for sale. It can be listed on the Marketplace without being in Showcase. Toggling one has no effect on the other. --- ## Subscriptions - **Free** — full access to upload, WiP documentation, showcase, marketplace listing, and commissions. 5% marketplace platform fee. 20% verifier job platform fee. - **Pro** — reduced verifier job platform fee (10%), priority features. Available monthly or annual billing. CoAs are not included in any subscription tier — always purchased separately as credits. --- ## Verity — AI assistant Verity is Veriroo's built-in AI assistant, accessible via the ✦ star button in the site header. She helps artists upload and document works, helps collectors discover art, and guides verifiers through jobs. Verity operates on a credit system: - Signed-out visitors: 5 AI-powered queries per day - Free accounts: 25 AI-powered queries per day - Guided flows, FAQ answers, navigation help, and upload assistance are always free and do not use credits Credits reset daily. --- ## Galleries and partners **Galleries** can showcase works they hold or exhibit, with clear attribution labels (e.g. "Exhibited by") that do not imply ownership. Consignment records are supported — consignor and custody are recorded; final sale triggers transfer and royalty split if configured. **Shops** can showcase stock items and verified editions. White-label CoA branding is available for retail and gallery partners. **Insurance partners** can use the Veriroo API for claim checks with signed, scoped tokens. Identifying owner data is redacted unless the owner authorises disclosure for a specific claim. --- ## Data and privacy Personal data is kept minimal and handled in accordance with GDPR. Public views show only what the user chooses to make visible. Identity is pseudonymised on public pages unless the user opts in to showing it. Verification Partners have NDA-bound, time-limited access to assigned items only and cannot access anything outside their assigned jobs. Draft uploads are temporary. Anything saved to a collection is kept permanently as the user's private canonical record. Verification, provenance, and audit records are preserved long-term. Account deletion requests are handled by anonymising the profile and removing personal fields where possible — provenance and audit records may be retained to maintain the integrity of the chain. --- ## Frequently asked questions **Can I sell without a subscription?** Yes. Free accounts can list and sell on the marketplace. The 5% platform fee applies to all tiers. **Do I need to show a visible QR on my artwork?** No. Discreet NFC tags are available for materials where a printed QR is undesirable. **Can I showcase works that are not for sale?** Yes. Showcase and Marketplace are independent. **What if a tag is lost or damaged?** Use the secure replacement workflow to link a new tag to the same record. The history is never affected. **Can I hide my collection?** Yes. Items are private by default. You control visibility per item. **Can the royalty rate be changed?** It can be changed while an item is unlisted. It locks permanently when escrow opens on the first sale and cannot be changed afterwards. **What currencies are supported?** Commissions use the artist's configured currency. Stripe handles international card payments and conversion. **Is Veriroo only for UK artists?** No. The platform is global — available wherever Stripe Connect supports artist/seller payouts. **What happens to unclaimed royalties?** Where a statutory artist resale royalty applies, the royalty is held in escrow for up to six years. If unclaimed, funds transfer into a restricted Artist Cultural & Integrity Fund and are never returned to the seller. **Can two verifiers disagree?** Yes. If two independent verifiers reach different conclusions, the item may be temporarily restricted from sale while evidence is reviewed. Veriroo may require additional verification before the item can be listed as verified again. **Can an inconclusive result be removed?** No. Verification history is never removed or overwritten. All attempts, including inconclusive outcomes, are recorded in provenance permanently. --- ## Key URLs - Homepage: https://veriroo.com/ - Marketplace: https://veriroo.com/marketplace/ - Showcase: https://veriroo.com/showcase/ - Verify a work (QR scan entry): https://veriroo.com/verify/ - FAQ and Help: https://veriroo.com/faq/ - Artist onboarding: https://veriroo.com/onboarding/artist.html - Collector onboarding: https://veriroo.com/onboarding/collector.html - Sign up: https://veriroo.com/signup/ - Roadmap: https://veriroo.com/roadmap/ - Sitemap: https://veriroo.com/sitemap.xml - AI summary: https://veriroo.com/llms.txt ## Company Veriroo is operated by Cardaroo Holdings Ltd, registered in England and Wales (company no. 16872413).
