.horizen: The Official TLD for the Horizen Ecosystem

Privacy only matters when it holds up in real-world usage.
That’s easy to say. Much harder to build for.

Real applications don’t operate in isolation. They move value, coordinate users, integrate with other systems, and run in public environments where assumptions break quickly. Privacy that works in theory often collapses once value, users, and public execution enter the picture.

Horizen exists in that reality.

As more builders design applications where privacy is part of normal execution, ecosystems begin to form around shared constraints, tools, and approaches. At that point, participation needs to become visible. Projects need to be findable. Alignment needs to be clear.

That’s where .horizen comes in.
As privacy becomes part of normal application execution, coordination changes. Discovery, identity, and signaling need to work without exposing sensitive operational details.

In collaboration with Horizen, we’re introducing .horizen, a Web3-only top-level domain created specifically for the Horizen ecosystem.

.horizen gives builders, applications, tools, and contributors a shared namespace that clearly signals participation in the network. It’s a way to anchor projects, surface ecosystem activity, and make Horizen easier to navigate as more teams build and deploy.

This naming layer is not about explaining Horizen to the outside world. It’s built for the people already operating inside the ecosystem.

Horizen is operating a live onchain environment focused on making privacy usable at application level.

Horizen has launched its mainnet as a Layer-3 appchain on Base, placing the ecosystem directly inside an Ethereum-aligned environment while inheriting Base and Ethereum security. This gives builders access to familiar tooling, liquidity paths, and infrastructure without sacrificing control over application design. Crucially, it enables privacy to be applied at the application level while remaining auditable and compatible with real-world requirements.

Beyond infrastructure, Horizen is committing resources to long-term ecosystem growth. The network runs a 1,000,000 ZEN builder funding  program. These funds are designed to support applications where privacy is part of normal execution, not an optional feature.

This combination of live execution, developer incentives, and ecosystem integrations has positioned Horizen as a network builders can deploy on today.

As ecosystems mature, naming becomes operational infrastructure.

.horizen provides a shared naming layer for the Horizen ecosystem, making it easier to identify which applications, tools, and contributors are building within the network. A .horizen name immediately communicates context and alignment without requiring explanation. In regulated and privacy conscious environments, that clarity matters.

Because “Horizen” is distinctive and non-generic, .horizen carries clear meaning. Projects using it are unmistakably part of the Horizen ecosystem.

This makes .horizen especially well suited for:

• Applications built on Horizen
• Developer tools and infrastructure
• Research initiatives and experiments
• Documentation, dashboards, and ecosystem hubs
• Contributors who want visible alignment with the network

As the ecosystem expands, these names help structure how Horizen is discovered and understood.

Every .horizen domain includes onchain functionality designed to support coordination and participation across the ecosystem:

🌐 Onchain websites
Launch applications, publish documentation, or host ecosystem resources.

🆔 UD.me profiles
Establish a portable onchain identity that reflects your role within Horizen.

💬 Messaging & Group Chat
Coordinate directly with other builders and contributors.

💸 Human-readable onchain payments
Use your name as a readable destination for onchain transactions.

Together, these tools make domains practical touchpoints for builders and contributors.

As the ecosystem grows, early names tend to become long-term reference points.

Early access to .horizen gives ecosystem participants the opportunity to secure names that reflect projects, tooling, and long-term intent before the namespace fills out. Each .horizen domain functions as a coordination surface, not just an identifier.

Think names like:

• build.horizen
• labs.horizen
• docs.horizen
• tools.horizen
• research.horizen

For teams planning to build on Horizen over time, these names become part of how the ecosystem organizes itself.

Horizen is growing, and the ecosystem now has a shared naming layer to match.

If you’re building on Horizen, contributing to the network, or planning to, .horizen gives you a name that clearly places you inside the ecosystem.
