Techavancées, as an innovative company in the field of Web3 software, offers a new approach to data storage with a focus on innovation in data security based on decentralized identity. With our technical expertise and the development of smart contracts on the Polygon network, we have created methods for decentralizing and tokenizing data and identities. This enables users to store their data without concern and share it securely with others.

Innovative service for seamless digital transformation
Establish secure and decentralized identities for individuals and organizations
Data is encrypted based on wallet address, decentralized identity, and other parameters, ensuring that no one but the owner can decrypt it
Storage is managed through smart contracts based on identities, 2FA, and other parameters—ensuring that from now on, data has a clear owner, and no one except the owner can download or transfer it
A fraud-resistant authentication method based on decentralized identity—whether individually or through multi-signature—grants access only after simultaneously verifying multiple parameters
From now on, every identity and every piece of data will have an identifier. We assign identifiers to data and identities. These identifiers are turned into tokens, and for transfers, all you need to do is give the token to someone or even take it back
Creation of real (DI) and legal (DAO) decentralized identities with the ability to connect to governments and organizations.


An innovative solution using decentralized OTPs that are no longer susceptible to phishing.
A unified signature based on decentralized identity that clearly shows who signed which document.
A framework that helps businesses tokenize their products and services for sale.
An intelligent structure to verify the authenticity of certificates, contracts, and tokens based on decentralized identities and blockchain signatures.
A unique structure for covering network transaction fees off-chain
A framework that enables you to create smart contracts for all your agreements with the conditions you define—contracts that are fraud-resistant (from sales agreements to even simple invoices).

A financial smart contract for blockchain-based payments that allows parties to hold funds until the work is confirmed. The purpose and participants of the payment are transparently recorded on the blockchain
Decentralized data storage is a necessary need, because traditional passwords are no longer secure anywhere

A tool that enables you to tokenize anything — and these tokens can no longer be forged or stolen

A unique structure that gives you a digital vault of documents and identities that you always carry with you, and allows you to verify yourself using the tokens you own

A tool that helps you cut off access to your data from any organization or website you no longer use or receive services from

A structure powered by smart contracts that helps store encrypted data on traditional databases (SQL, NoSQL, etc.), making them hack-resistant
Techavancées addresses the problem of data insecurity by using tokenization and decentralized storage. We enable individuals to manage and control their own data and identity documents, removing the risks associated with centralized systems. Through tokenization, each piece of data and identity is uniquely secured—making unauthorized access and manipulation nearly impossible.
