Why choose us ?

Tamper-proof, permanent, universal and transparent evidence

The highly decentralized nature of the Tezos blockchain is an effective alternative to trusted third parties solutions. It inherently allows the management of authentication as well as time-stamping and immutable storage of the proofs constituted during the signature process.

These proofs are universally valid and can be verified independently of any third party.

Based on the use of a high-quality public blockchain, Tediji is the first electronic signature solution on the market that meets the definition of an Electronic Register as defined by eIDAS regulations, opening the door to many new use cases.

Cost-effective and environmentally friendly

Our massification algorithm together with low transaction costs on the Tezos blockchain allow us to offer very competitive pricing compared to traditional solutions. With Tediji, you will be able to sign all the documents that deserve it !

In addition, the Tezos blockchain is known for its particularly low carbon footprint (its total consumption in 2021 was equivalent to that of 17 global citizens) and its efficiency keeps on improving.

A business solution

Our product is designed specifically for business needs. With Tediji, you can process all volumes of files and generalise your use cases for electronic signatures and content time-stamping. Hosted on a highly secure infrastructure designed for large volumes, we offer our customers and SAAS publisher partners open APIs at no extra cost.

Tediji, compliant with eIDAS regulations on electronic signatures

Tediji complies with the simple signature level defined by the eIDAS regulation of 23 July 2014. Subject to combining it with an identity verification policy, it also complies with the advanced electronic signature level. 
The simple signature represents more than 80% of signatures on the market  and is suitable for documents for which:

  • There is no legal obligation to use an advanced or qualified signature (e.g. notarial deeds must be signed with a qualified signature in France).
  • Disputes based on the rejection of a contract on the grounds of its form rather than its substance are rare and relate to well-understood legal and/or financial issues. 
  • Additional evidence may be provided to strengthen the proof of consent. 

In terms of its time-stamping and certification function, Tediji is also the only solution on the market to be natively compatible with the concept of Electronic Registers as described in the eIDAS 2.0 regulation of April 2024.

Tediji, a low-cost electronic signature pricing model

We offer a pricing model based on the volume of signatures.

Thanks to the ability to bulk-process signatures on the blockchain, we can offer particularly competitive rates for large volumes of signatures.

Based on your monthly or annual target volume of signatures, we will offer a package corresponding to a minimum commitment volume.

Above this minimum commitment threshold, a predefined unit cost will be applied.

The higher your commitment volume and/or consumption volume, the lower the unit price will be.

  • Certification: up to 100 times cheaper than the competition for very large volumes.
  • Electronic signature: up to 10 times cheaper than the competition for very large volumes.

Get ready for tomorrow

Decentralisation, blockchain and cryptoassets are becoming more widespread and are gradually revolutionising the practices of individuals and businesses. In April 2024, the European Union confirmed the relevance of blockchain for managing digital evidence through the use of electronic registers, the definition of which corresponds to that of blockchains.
Digital identity is undergoing a transformation, and tomorrow's exchanges between businesses and individuals will take place via digital identity wallets. Based on blockchain technology, Self-Sovereign Identity solutions allow users to control their identification data, thereby establishing a new framework of trust.
Tediji is the first software publisher to work on integrating these innovations into an electronic signature solution: identity, storage, decentralised application, cryptoasset payment, etc.

FAQ – Everything you need to know about electronic signature

What is blockchain-based electronic signature?

Blockchain-based electronic signature is a simple electronic signature within the meaning of the eIDAS regulation, whose evidence is timestamped and anchored in a public distributed ledger (Tezos). Unlike traditional PKI solutions, the proof does not depend on any central trusted third party and remains verifiable indefinitely.

Is Tediji compliant with eIDAS?

Yes. Tediji complies with the simple electronic signature defined by the eIDAS regulation of 23 July 2014, which covers more than 80% of business needs (employment contracts, leases, quotes, delivery records).

What is the difference between Tediji and DocuSign or Yousign?

Tediji differentiates itself through the use of the Tezos blockchain as a timestamping ledger, eliminating dependence on a trusted third party. Its pricing is up to 10 times lower on high volumes, starting from €0.03 per signature.

Does blockchain have legal value in France?

Yes. In March 2025, the Paris Civil Court recognised the probative value of a blockchain timestamp as "prima facie evidence in writing". eIDAS 2.0 (2024) also provides a framework for electronic registers, whose definition corresponds to public blockchains.

For which documents can simple electronic signature be used?

Simple electronic signature is suited to employment contracts, lease agreements, quotes, delivery records, membership forms, supplier contracts, and any document that does not require an advanced or qualified signature.

Is Tediji suited to large enterprises?

Yes. Tediji is designed for large accounts and mid-sized companies with high volumes, thanks to open REST APIs at no extra cost, iFrame integration, Microsoft 365 connectors, and a scalable microservices architecture.

How do I integrate Tediji into my applications?

Tediji offers documented REST APIs, webhooks, embedded signature via iFrame, and native connectors (SharePoint, Teams, Outlook, Nuxeo, Bonita). API access is included at no extra cost in all plans.

How much does electronic signature cost with Tediji?

Pricing starts from €0.03 per signature and €0.003 per certification, with volume-based discounts. Tediji is up to 10 times cheaper than traditional solutions at high volumes.
