What is Chromia Development Skill?
The Chromia Development Skill empowers AI agents to handle the end-to-end lifecycle of building decentralized applications (dApps) on Chromia. This includes mastering the Rell relational language, managing the Chromia CLI, and integrating advanced features like FT4 accounts and cross-chain messaging. By utilizing Openclaw Skills like this one, developers can automate complex blockchain engineering tasks while ensuring strict adherence to security and determinism guardrails.
The skill focuses on maintaining high standards in Postchain client alignment and TypeScript integration. It provides a structured approach to blockchain development, distinguishing itself from traditional smart contract platforms by leveraging a relational model that scales efficiently and integrates natively with modern web technologies.
Chromia Development Skill Use Cases
- Building relational dApps using the Rell programming language.
- Configuring multi-chain environments via chromia.yml.
- Implementing secure wallet-based (FT4) or key-based authentication patterns.
- Deploying and managing blockchain containers through the Chromia CLI.
- Integrating AI extensions like vector databases and on-chain inference for smart contracts.
How Chromia Development Skill Works
- Initialize the project structure using chr create-rell-dapp and configure the module entry points in the YAML configuration.
- Define the relational schema using entity and struct blocks within the Rell source files for persistent data storage.
- Implement business logic through operations and queries, applying the @mount namespace for seamless client accessibility.
- Configure authentication handlers and module arguments while maintaining a zero-secret policy for private keys.
- Execute unit tests with chr test and validate the dApp on a local Postchain node using chr node start.
- Manage the deployment lifecycle including container creation and updates across testnet or mainnet environments using the deployment pipeline.
Chromia Development Skill Setup
To use this within the Openclaw Skills framework, ensure the Chromia CLI is installed on your system. Follow these steps to prepare your environment:
# Install Chromia CLI globally
npm install -g @chromia/cli
# Install project dependencies specified in chromia.yml
chr install
# Start a local node for testing and development
chr node start --wipe
Ensure your agent has read/write access to the project directory to manage the chromia.yml and Rell source files.
Chromia Development Skill Data Schema & Taxonomy
The skill organizes data into a clean hierarchy for both backend and frontend components, ensuring consistency across the dApp.
| Component | Description |
|---|---|
| chromia.yml | The project root configuration containing module mappings and library definitions. |
| src/ | Rell source code including entities (tables), operations (writes), and queries (reads). |
| src/test/ | Unit and integration test modules referenced in the test.modules config. |
| client/ | TypeScript/Frontend integration using postchain-client and @chromia/ft4. |
It utilizes a strict relational taxonomy where entities map directly to database tables, and module_args define the runtime environment for each blockchain module.
Chromia Development Skill Advanced Features
