Chromia CHR / Chromia

What Is Chromia (CHR)?

Chromia is a Layer-1 modular relational blockchain designed for building scalable and customizable decentralized applications. Chromia supports standalone applications, EVM-interoperable Layer-2 enhancements, and can serve as a decentralized infrastructure layer for data-intensive use cases such as AI, gaming, and more. The native token, CHR, was launched in May 2019.

Some examples of applications on Chromia include: My Neighbor Alice, a multiplayer builder and farming game; Mines of Dalarnia, an action-adventure game; EVAL Engine, an AI Agent Evaluation Plugin; Fanzeal, a digital collectible and fan engagement platform for club for sports and E-sports; and ColorPool, a DeFi platform offering a gas-free decentralized exchange, liquidity pools, staking, and integrated mini-games.

What Makes Chromia Unique?

Chromia is built on a unique relational blockchain architecture, allowing Chromia to support complex, data-intensive applications that would be difficult or expensive to run on traditional blockchains.

The platform uses a modular design, allowing developers to integrate optional components known as Extensions. These extensions can provide a variety of on-chain features like vectorized data, AI inference, and oracles.

Chromia stands out as an ideal platform for AI development due to several innovative features. The Mimir Mainnet Upgrade, released in March 2025, included the Vector Database Extension, enabling on-chain management of vectorized data essential for AI applications. The upgrade also introduced the AI Inference Extension, which aims to support hosting LLMs directly on network nodes, reducing reliance on centralized services. The platform's ongoing integration with LangChain, a leading AI agent framework, further expands support for decentralized, intelligent applications. Chromia’s relational database structure and independent dapp chains provide a scalable and developer-friendly environment for cost-effective and performant AI solutions.

Chromia also serves as an interoperable enhancement layer for Ethereum and other EVM chains. EVM-based projects can use Chromia to build companion dApps or store more complex and structured metadata, reducing reliance on centralized solutions.

Every application on Chromia runs on its own independent blockchain. This design allows each dApp to scale independently and define its own rules, governance, and fee models for optimal scalability and customization.

Chromia uses an economic model that resembles traditional hosting. Deployers pay CHR tokens to cover hosting costs, after which they have unrestricted access to their chain’s resources.
