Our approach

Data Integrity and immutability

Company can take advantage of blochain to improve data integrity to the highest standards. By design, blockchains are inherently resistent to the modification of data. Blockchain ledgers are immutable meaning that if data addition or transaction has been made, it cannot be edited or deleted.

    Digital Assets Descentralized

    Blockchain allows the storing and exchange of assets and valuable information between two entities anywhere in the world in a secure, transparent and immutable way without the need for a trusted centralized authority to authenticate parties and validate transactions. It is a promising approach to transforming society and changing how we trust individuals and institutions.

      Non Fungible Tokens (NFT)

      An NFT is a unit of data stored on a digital ledger, called a blockchain, which can be sold and traded. The NFT can be associated with a particular digital or physical asset (such as a file or a physical object) and a license to use the asset for a specified purpose.

        Supply Chain Management

        Improve supply chain visibility to all parties with a custom blockchain that can provide data integrity and trust. Any participant can register any relevant data such as price, date, location, quality, certification, ... and improve visibility and traceability of supply chains.

          Crypto Wallets

          Unlike a normal wallet, which can hold actual cash, crypto wallets technically don't store your crypto. Your holdings live on the blockchain, but can only be accessed using a private key. Your keys prove your ownership of your digital money and allow you to make transactions. If you lose your private keys, you lose access to your money. Crypto wallet allows you to store your private keys and to send, receive, and spend digital money; browse and use DeFi applications, and more.

            Crypto Tokens

            Either as currency, good, shares or rewards, tokens are the engine of your digital business based on blockchain and it is the one that its users will give value.

              What they say about us

              Fantastic Team. I've worked with almost all Etéreo developers in a large-scale re-launch project for one of Spain's most innovative Telcos. They had a great quality mindset, always trying to improve but also striking a good balance between perfect code and making necessary trade offs to hit critical deadlines. They were instrumental in getting the re-launch off the ground in short time and high quality. Would be very happy to work with Etéreo again.
