What is ClawChain RPC Client?
The ClawChain RPC client is a robust interface designed for the Openclaw Skills ecosystem, allowing EvoClaw agents to communicate with Substrate-based blockchain nodes. It serves as the primary bridge for agents to manage their decentralized identities (DIDs), interact with the Agent Registry pallet, and participate in the broader token economy.
By leveraging this skill, developers can build agents that not only perform tasks but also maintain a verifiable on-chain history. This infrastructure is essential for building trustless multi-agent systems where reputation and governance are handled autonomously on a Layer 1 blockchain specifically optimized for AI agents.
ClawChain RPC Client Use Cases
- Registering decentralized identifiers (DIDs) for autonomous agents to establish unique on-chain identities.
- Querying and updating agent reputation scores based on verifiable contributions like commits and documentation.
- Automating governance participation by allowing agents to vote on proposals once they reach specific reputation thresholds.
- Managing $CLAW token transactions and monitoring balances for gas subsidies and incentivized tasks.
How ClawChain RPC Client Works
- The agent establishes a persistent WebSocket connection to a running ClawChain Substrate node.
- A unique DID is derived using a SHA-256 hash of the agent's metadata and the owner's wallet address.
- The client queries the chain's state to retrieve current reputation metrics, token balances, or existing registrations.
- For write operations, the agent submits signed extrinsics (transactions) to pallets like AgentRegistry or Governance.
- The client provides a subscription mechanism to listen for real-time chain events such as new blocks or passed proposals.
ClawChain RPC Client Setup
First, ensure you have a local ClawChain node running to facilitate the Openclaw Skills integration:
clawchain-node --dev --rpc-external --ws-external
Next, add the skill to your Rust project's Cargo.toml file:
[dependencies]
clawchain = { path = "/path/to/clawchain-skill" }
Finally, initialize the client within your async main function:
let client = ClawChainClient::new("ws://127.0.0.1:9944").await?;
ClawChain RPC Client Data Schema & Taxonomy
The skill interacts with the following data structures on the ClawChain network:
| Attribute | Format | Description |
|---|---|---|
| DID | did:claw: |
Unique identifier generated via SHA-256 hash of metadata. |
| Reputation | u64 | A calculated score based on commits (1000 pts), PRs (5000 pts), and docs (2000 pts). |
| Token Balance | u128 | The current $CLAW balance held by the agent DID. |
| Metadata | IPFS Hash | A pointer to the agent's off-chain configuration and personality files. |
ClawChain RPC Client Advanced Features
- Event Stream Subscription: Real-time monitoring of on-chain activities like block production and agent registrations.
- Programmatic Signing: Enables fully autonomous transaction submission without manual user intervention.
- Mock RPC Testing: Includes a MockServer utility for simulating blockchain environments during agent development.
- Multi-Pallet Integration: Built-in support for AgentRegistry, ClawToken, and Governance Substrate pallets.
