Frequently Asked Questions

Yes! KALIS certification is 100% free for creators. You can create as many certificates as you want without paying. We only earn revenue through a 5% commission on sales made via the platform. If you don't sell, you don't pay.

Every time one of your certified works is resold, you automatically receive 5% of the sale price thanks to smart contracts on the Unikium blockchain. On subsequent resales, the total commission is 7.5% (5% for the creator, 2.5% for KALIS). It's automatic and transparent.

RoyaltyLink is a unique sales link that you can share on your social media, website, or via message. When a buyer purchases through this link, the transaction is recorded on the blockchain and your royalties are automatically activated for future resales.

No, the NFC chip is optional. Digital certification (QR code + blockchain certificate) is completely free. The encrypted NFC chip (€19.90 excl. VAT) is attached to your creation for instant smartphone scanning. Packs are available from €79.90 excl. VAT (5 chips). It is recommended for physical works (paintings, sculptures, jewelry).

The Pioneer Program is reserved for the first creators who join KALIS. As a pioneer, you benefit from free premium features and dedicated support. Spots are limited.

Kalicertif is a blockchain-based digital certification platform. We enable artists, manufacturers, and professionals to create tamper-proof certificates of authenticity for their products and documents.

Not at all! We handle all the technical aspects. You create your certificate like a simple online form, and we take care of the blockchain anchoring, QR code generation, and NFC linking.

No. Everything happens via the web browser. Your clients scan the QR code or NFC chip with their smartphone, and the certificate displays instantly — no app download required.

Yes! The ownership transfer is recorded on the blockchain, creating a complete and verifiable ownership history. It's ideal for art resales or product tracking in the supply chain.

The NFC chip is a small electronic component (about 1cm in diameter) that you discreetly attach to the work (on the back, in the frame, on the base). When someone brings their smartphone close, the certificate displays automatically.

No. Each NFC chip contains a unique cryptographic identifier that cannot be duplicated. It's the same technology used in bank cards and passports.

The certificate includes: the title of the work, the artist, dimensions, technique, photos, creation date, ownership history, and the blockchain hash as proof of authenticity.

You can order individually (€19.90 excl. VAT/chip), in a Creator Pack (€79.90 excl. VAT for 5 chips), or in a Gallery Pack (€249 excl. VAT for 20 chips). For larger volumes, contact us.

The Digital Product Passport (DPP) will be mandatory in the European Union starting in 2027 for textiles, batteries, and electronic products. Non-compliant companies risk fines and bans from selling on the European market.

The first targeted sectors are batteries (2027), textiles (2027), and electronics (2028). The ESPR regulation provides for a gradual extension to other product categories.

Yes. Our REST API enables integration with most ERPs and management systems (SAP, Odoo, etc.). We also offer CSV import for companies that prefer a no-code solution.

On average, 12 to 18 months for full compliance: data audit, structuring, technical integration, and team training. Start now to be ready by 2027.

No. Kalicertif generates a certified copy with a QR code. Your original document remains intact. The cryptographic hash is computed from the original file.

Blockchain timestamping constitutes recognized proof of prior existence. The Kalicertif certificate can be used as evidence in a legal context, particularly to prove the existence of a document at a given date.

Yes. Only the cryptographic hash is stored on the blockchain, not the document content. Your data remains private and is never shared.

PDF, images (JPEG, PNG), Office documents (Word, Excel). PDF format is recommended as it allows direct integration of the verification QR code.

We use Unikium, our proprietary blockchain built on Avalanche technology. Fast transactions, low costs, and enhanced security. Each certificate is permanently anchored and publicly verifiable.

Your certificates remain accessible. The data is anchored on the Unikium blockchain, which is decentralized and publicly verifiable. You can always view a certificate directly on the blockchain.

The cryptographic hash and essential metadata are stored on-chain. Large files (images, PDFs) are stored on secure servers with the on-chain hash as proof of integrity.

Our infrastructure guarantees a 99.9% SLA for Premium plans. Blockchain data is available 24/7 since it resides on a decentralized network.

Yes, you can upgrade or downgrade at any time. The change takes effect immediately and the prorated amount is calculated automatically.

No. All our subscriptions are commitment-free. You can cancel at any time from your account dashboard.

Payment is secured via Stripe. You can pay by credit card (Visa, Mastercard, AMEX). Subscriptions are renewed automatically.

Yes. We offer discounts for associations, educational institutions, and cultural projects. We also provide volume-based pricing. Contact us to discuss your needs.
