/**4THTECH currently consists of four main products, which form the framework for future sollutions:

“I see amazing possibilities in the 4THPILLAR TECHNOLOGIES products. The FOURdx, eDelivery serves as a system for sensitive document distribution between organizations and individuals and is based on blockchain technology. A truly innovative and amazing solution.”

Igor Zorko, ZZi


EU technology pioneers

4THTECH infrastructure currently consists of four finished blockchain-based products; (1) FOURdx (i.e. document exchange protocol/eDelivery); (2) FOURid (i.e. digital identification mechanism); (3) 4THTECH ADD-ON (i.e. Google-extension with build-in asset management); (4) FOUR-TOKEN, and; (5) HI-WISE (i.e. hardware & mobile wallet of the future).

1.FOURdx- eDelivery and document exchange

FOURdx is a protocol that allows its users to exchange and safely store sensitive digital assets among each other. FOURdx blockchain-based multiple wallet and document management system is capable of: (1) connecting senders and receivers by executing document exchange; (2) performing eDelivery based on the current EU legislation, and; (3) AES and RSA document encryption, and; (4) archiving secure encrypted data storage. FOURdx protocol is designed and build based on blockchain-technology, tested on KOVAN network and implemented on ETHEREUM main net in Q3 2018. Designed and build from the ground-up in Solidity the product is fully operational, compatible and ready for implementations.

Product integration options

FOURdx blockchain eDelivery document exchange can be implemented three ways: (1) adopting existing 4THTECH, Ethereum based infrastructure (i.e. central platform with document repository, encryption service and API interface, chrome ADD-ON and HI-WISE hard wallet system), using FOUR tokens for gas to fuel the document exchange transactions; (2) using 4THTECH specific modules (i.e central platform, document repository, encryption service, APIs, FOURdx protocol, chrome ADD-ON or HI-WISE hard wallet system) to construct white-label solution, and; (3) migrating to any other Solidity based blockchain, using 4THTECH solution modules according to you needs.  

How does it work?

For easier FOURdx process understanding we created operational segments; (1) the document is uploaded to the FOURdx API (i.e. currently limited to 20MB file size); (2) the document is stored in the repository; (3) the user is provided with the “link” of the saved location; (4) the link is sent to the blockchain, and; (5) the recipient can download the document and decrypt it with his private key saved in the browser’s ADD-ON.

2.FOURid – Blockchain based individual digital identification mechanism

FOURid derives as a direct result of the FOURdx protocol. To provide an option for blockchain address ownership verification, the verification mechanism was created. It offers the establishment of blockchain-based individual digital identity and allows users to become verified, authenticated and seen in the vastness that is blockchain. Designed and build from the ground-up in Solidity the product is fully operational and offers; (1) user onboarding authorization through a KYC identification process; (2) assignation of user’s public and private key, and; (3) wallet address verification.


The 4THTECH ADD-ON is a Google Chrome extension that allows you to visit the distributed web of tomorrow in your browser today. It is one of our main innovations, a first system on the market capable of handling not only digital assets but also other assets such as links to encrypted documentation. Designed and build from the ground-up, the 4THTECH ADD-OD is fully operational and also offers a secure identity vault, providing a user interface to manage FOURid identities and sign blockchain eDelivery transactions.


Steps for installation; (1) follow on the link bellow; (2) add extension to chrome browser; (3) now you have installed extension, you can see icon on the right side; (3) click on that icon and setup your wallet; (4) refresh page and login.


4THPILLAR does not hold your keys for you. We cannot access accounts, recover keys, reset passwords, nor reverse transactions. Protect your keys & always check that you are on correct URL. You are responsible for your security.


The FOUR-TOKEN has been created as a 100% utility token, an atomic unit and technical component, combining three unique main features; (1) embedded token teleportation-service; (2) multiple-transfer option, and; (3) main value and “gas” in a decentralized, token-based 4THPILLAR ecosystem. To use the FOURdx-eDelivery service, the FOUR tokens are needed in order to fuel the transactions. The number of tokens is fixed, thus, there cannot be any inflation effect. As the adoption of the 4THPILLAR network and FOUR token transaction volume within the network grow, the demand for the FOUR token increases.


Token name: 4THPILLAR UTILITY TOKEN • Token symbol: FOUR • Blockchain: Ethereum • Maximum number of FOUR tokens issued: 400,000,000 (100%) • Decimals: 18 • Smart contact: 0x4730fb1463a6f1f44aeb45f6c5c422427f37f4d0 • Unique features: teleportation service, multiple-transfer option, transaction gas • Listing: LaToken • Token standard: ERC-20 (latest Open Zeppelin implementation)

5.The 4THTECH HI-WIZE hardware wallet

HI-WISE is an advanced PLUG&PLAY hardware wallet with futuristic uni-body design. Unique to the market, the HI-WISE has no openings and buttons, just a HI definition LCD display and it is powered by Qi charging technology. Accompanied by unique mobile multi-wallet with unparalleled safety features and integrated anti-spying algorithms. The HI-WISE hardware and mobile solution bridges the gap between the FOURdx – eDelivery platform and final user experience. The HI-WISE can be used as an alternative to 4THTECH add-on, providing platform login, identification and transaction conformation features.
