Irys.xyz is the online home of Irys, a blockchain infrastructure platform focused on programmable onchain data. Unlike blockchains primarily optimized for smart contract execution, Irys is designed as a “datachain” – a network structured to store and process data directly onchain at scale. According to the company, its goal is to make data not only storable, but also verifiable, traceable, and programmable across applications. In June 2024, Irys announced a $3.5 million funding round led by Lemniscap, bringing its total raised to $8.9 million. As reported by The Block, investors in the round include Framework, Primitive Ventures, Hypersphere, Permanent Ventures, and others.1
According to Irys, the platform is structured to address several limitations of earlier blockchains and datachains, including the challenges of static data, high storage costs, and centralization. Irys incorporates a multi-ledger architecture that supports data transitions from temporary validation to permanent storage. A system of ingress proofs and metadata is used to establish verifiability. IrysVM, the platform’s virtual machine, is designed to enable smart contracts to interact directly with stored data—supporting programmable and adaptable data within applications. These features are intended to support use cases involving provenance, traceability, and automated execution, including applications that intersect with AI-generated or manipulated data.
Irys is founded by Josh Benaron, who currently serves as CEO. According to his LinkedIn profile, Josh launched Irys in 2021 following roles as a consultant at technology and advisory consultancy VantagePoint and an intern at Found, a marketing agency focused on search performance. Under his leadership, Irys continues to focus on developing scalable infrastructure intended to support programmable onchain data and increase data accessibility across decentralized ecosystems.
The platform’s selection of the .xyz domain reflects its positioning as one focused on innovation and interoperability. .XYZ offers a flexible, neutral identity suited for technologies that aim to operate across ecosystems. Irys.xyz supports a memorable and forward-looking brand identity for a platform working to redefine how data is handled, verified, and deployed in decentralized systems. Additionally, Irys.xyz is short and easy to remember, which can make it easier for developers, users, and partners to find and revisit the platform. A concise domain also supports strong branding and helps maintain consistency across digital touchpoints, including email and social media.

Fluent.xyz is the online home of Fluent, a blockchain platform built as a Layer-2 network on Ethereum. Fluent is designed to help developers build apps using different programming tools in one place. It does this by combining support for multiple types of smart contract systems – known as virtual machines (VMs) – into a single environment where they can work together. In February 2025, Fluent Labs announced that it raised $8 million in funding led by Polychain Capital, with support from investors including Primitive, dao5, and Symbolic Capital.1
According to Fluent Labs, the platform is designed to combine elements of several blockchain systems, including Ethereum’s EVM, Solana’s SVM, and WebAssembly (Wasm). These systems usually operate separately, but Fluent is designed to help apps written for them interact smoothly and instantly. Developers can use different programming languages like Solidity and Rust, and Fluent converts their apps into a shared format that works across its platform. This approach is aimed at removing the limitations that come from working in just one blockchain system. Fluent also offers a set of tools—called the Fluentbase framework—that, according to the project’s documentation, helps developers launch apps, customize how they run, and connect them to other parts of the blockchain ecosystem.
The platform is founded by CEO Dino Savonin and CTO Dmitry Savonin. To engage the developer community, they host Fluent Fridays, a recurring online event where people share smart contract projects written in Solidity or Rust. According to Fluent’s GitHub, participants gather on the Discord every two weeks to talk about submissions, and one project receives a $250 prize. The event encourages exploration and experimentation on the Fluent platform.
Choosing a .xyz domain name reflects Fluent’s focus on flexibility and broad access. .XYZ offers broad appeal, with no ties to a specific region or industry. This makes it well-suited for a platform like Fluent, which is designed to support a wide range of tools, programming languages, and blockchain communities.
