One blockchain project that has gained attention for its innovative approach is Horizen, driven by a vision to create a more inclusive and secure digital future. In this article, we will explore the Horizen ecosystem, EVM compatibility through the EON sidechain, and how developers can leverage Horizen Nodes with the Tatum SDK for Dapp development.

What Is the Horizen Blockchain?

Horizen, is an innovative and decentralized blockchain ecosystem that prioritizes decentralization, security and selective privacy. It stands out in the blockchain landscape for its commitment to providing users with a decentralized and secure infrastructure, ZK-powered cross-chain communications, and zk-enabled privacy. Horizen allows developers to build and deploy decentralized applications (Dapps) while emphasizing user experiences, efficiency, data protection and anonymity. With a focus on user empowerment and data security, Horizen offers a robust and reliable foundation for a wide range of blockchain-based projects and applications.

EVM Compatibility and the EON Blockchain

EVM (Ethereum Virtual Machine) compatibility has become a key feature for many blockchain projects. It allows developers to migrate Ethereum-based Web3 apps to other chains with minimal modifications. Horizen accomplishes EVM compatibility through its sidechain platform, EON.

EON enables developers to create Ethereum-compatible Dapps, meaning that smart contracts and Dapps designed for Ethereum can be deployed on Horizen's network with ease. This compatibility opens up a wide range of possibilities for developers, making it easier to port their existing projects to the Horizen ecosystem.

End-to-End SDK for Dapp Development on Horizen using Tatum SDK

To facilitate Dapp development on the Horizen blockchain, Tatum provides an end-to-end SDK (Software Development Kit) that simplifies the entire process. This SDK includes tools for creating and testing their Web3 apps also deploying smart contracts, as well as APIs for interacting with Horizen Nodes.Thanks to Tatum SDK, developers can build their Web3 app with Horizen nodes via Unlimited RPC network, mint NFTs, create and manage wallets or enhance user experience their customers via notifications. You can find more in technical documentation.

Using Horizen Nodes Powered by Tatum’s Unlimited RPC

The Unlimited RPC Initiative by Tatum is a significant step forward in simplifying blockchain development and making blockchain accessible for everyone. It provides developers with a set of tools and infrastructure to easily build and deploy Dapps on various blockchain networks. In the case of Horizen, developers can leverage Tatum's infrastructure to interact with Horizen Nodes seamlessly. Horizen Nodes, which serve as the backbone of the network, validate transactions, maintain the blockchain's security, and enable communication with Dapps.

Enabling NFT Minting Through the Tatum SDK

In the rapidly evolving world of blockchain and Dapp development, the creation of NFTs (Non-Fungible Tokens) has become a significant trend. With Tatum's integration into the Horizen ecosystem, developers can harness the power of NFT minting with ease. Tatum's toolkit and infrastructure simplify the process of creating and managing NFTs, providing Dapp creators with the tools they need to bring unique and valuable digital assets to life. This integration enhances the already exciting potential of the Horizen ecosystem, offering a seamless solution for those looking to explore the world of NFTs and extend the capabilities of their decentralized applications.

Empowering Dapp Development with Wallet Provider Integration

The Wallet Provider feature, integrated into Horizen through Tatum SDK, is a game-changer for Dapp developers. It simplifies wallet management by supporting multiple cryptocurrencies, including Horizen's ZEN. With this feature, Dapp users can easily create and manage their wallets, securely store private keys, and manage transactions all within the Dapp interface. Security is a priority, as Tatum ensures the encryption and secure storage of private keys. This feature not only simplifies user experience but also broadens the Dapp's utility by offering multi-currency support

Enhancing User Experience with Real-Time Notifications

The Notification feature within Tatum SDK enhances the user experience by providing real-time updates and alerts for Web3 app users on the EON blockchain. Users can receive instant transaction updates, know the status of their ZEN transfers. Real-time notifications foster user engagement and trust, ensuring users remain well-informed about their incoming and outcoming transactions in wallets, NFT events or smart contract events.


Horizen is excited to see developers and businesses harness the power of its blockchain, and Tatum empowers them to do so with ease. By providing the necessary blockchain infrastructure and tools, Tatum removes many of the barriers to entry in blockchain development, allowing innovators to focus on creating groundbreaking Dapps.
