# ClawChain RPC Client

Connect EvoClaw agents to the ClawChain blockchain for on-chain reputation tracking, token economics, and governance participation.

## Quick Start

```rust
use clawchain::ClawChainClient;

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    // Connect to local node
    let client = ClawChainClient::new("ws://127.0.0.1:9944").await?;
    
    // Query agent reputation
    let did = "did:claw:1a2b3c4d...";
    let reputation = client.get_agent_reputation(did).await?;
    println!("Reputation score: {}", reputation);
    
    // Check token balance
    let balance = client.get_token_balance(did).await?;
    println!("CLAW tokens: {}", balance);
    
    Ok(())
}
```

## Prerequisites

1. **ClawChain node running:**
   ```bash
   clawchain-node --dev --rpc-external --ws-external
   ```

2. **Rust dependencies in Cargo.toml:**
   ```toml
   [dependencies]
   clawchain = { path = "/path/to/clawchain-skill" }
   ```

## Key Concepts

### Agent DIDs

Agent identifiers follow the format:
```
did:claw:<hash>
```

Where `<hash>` is SHA-256(agent metadata + owner address).
