Terms of Service

Last updated: 2026-05-28 (testnet preview draft).

1. What certi.art is

certi.art is a smart-contract-based system on Ethereum for issuing soulbound identity tokens (SBT), Certificates of Authenticity (CoA) for fine art, and 1/1 Digital editions. At MVP we operate on Sepolia testnet; mainnet activation requires external audit sign-off.

2. Not a guarantee of authenticity

A certi.art CoA is a supplementary on-chain attestationcreated by an artist (or by an authorized gallery on the artist's behalf). It is nota legal substitute for traditional provenance, expert appraisal, or physical chain-of-custody documentation. Buyers and collectors must perform their own due diligence.

3. Eligibility

You must be at least 18.
You must have the legal right to issue a certificate of authenticity for the work you register (you are the artist, or an authorized representative).
You must not be a sanctioned person or located in a sanctioned jurisdiction.

4. Free tier and fees

At MVP, registration as an Artist and minting your first CoA + first Digital are gas-sponsored by certi.art (you sign nothing on-chain that costs you ETH). Subsequent mints may require payment of gas or a platform fee; the platform fee, if any, will be disclosed before each transaction.

5. Royalties

On secondary resale of a Digital edition, the contract enforces an EIP-2981 royalty up to a maximum of 10% to the address you designated at mint. CoA tokens are non-tradeable attestations; royalties apply only to Digitals.

6. Soulbound profiles

Artist, Gallery, and Institution profiles (SBTs) are non-transferable by design(ERC-5192). They are tied to the wallet that minted them. Linking additional wallets is possible (up to 10) via the on-chain linkWallet path.

7. Galleries and authorization

Galleries are admitted by certi.art after off-chain KYB (business registry check, basic reputation review). Once admitted, a gallery can request authorization from a registered artist to mint CoAs on their behalf within the cap and expiry the artist signs. Authorization is on-chain and revocable at any time.

8. Disputes and revocations

Tokens can be marked DISPUTED or REVOKED by certi.art on cause (clear evidence of forgery, fraud, or court order). This is on-chain and visible to anyone. We do not refund secondary purchases; collectors should check on-chain status before transacting.

9. Your data, your erasure

See the Privacy Policy. Your identity metadata (display name, bio, artwork image) lives on IPFS and can be unpinned on request, breaking the public link from your wallet to your name. The wallet address itself and the existence of the token remain on-chain.

10. Acceptable use

No infringing or stolen artwork.
No misrepresenting authorship.
No automated abuse of the free-tier quotas.
No attempts to bypass authorization, royalty, or other on-chain restrictions.

Violations may result in tokens being marked DISPUTED/REVOKED and the wallet being denied future free-tier sponsorship.

11. Limitations of liability

certi.art and its operators do not warrant uninterrupted service, error-free smart contracts, or the persistence of any IPFS gateway. To the maximum extent permitted by law, liability is limited to fees you actually paid in the previous 12 months (which, on the free tier, is zero).

12. Governing law

Polish law. Disputes that cannot be resolved informally are subject to the courts competent for the seat of the operator, without prejudice to mandatory consumer protections under EU law.

13. Changes

We will post a new version with a new “Last updated” date here. Material changes will be flagged in the app to active wallet holders.
