# Contract Inspection

Execute Pact code across chains to inspect smart contracts, query module information, and analyze on-chain state.

## PactQuery: Multi-Chain Contract Inspection

Execute arbitrary Pact code across multiple chains simultaneously to inspect smart contract modules and retrieve contract details.


```graphql
query PactContract($pactQuery: [PactQuery!]!) {
  pactQuery(pactQuery: $pactQuery) {
    result
  }
}
```

**Variables**


```json
{
  "pactQuery": [
    {
      "code": "(describe-module \"coin\")",
      "chainId": "0"
    },
    {
      "code": "(describe-module \"coin\")",
      "chainId": "1"
    }
  ]
}
```

**Response** *(truncated for brevity)*


```json
{
  "data": {
    "pactQuery": [
      {
        "result": "{\"hash\":\"klFkrLfpyLW-M3xjVPSdqXEMgxPPJibRt_D6qiBws6s\",\"interfaces\":[\"fungible-xchain-v1\",\"fungible-v2\"],\"name\":\"coin\",\"code\":\"(module coin GOVERNANCE...\"}"
      }
    ]
  }
}
```

**Use Cases**

- Smart contract module inspection
- Contract code verification across chains
- Module interface discovery
- On-chain state queries
- Development and debugging tools


**Notes**

- Query all 20 chains by providing 20 objects with chainIds "0" through "19"
- Use `(describe-module "module-name")` for contract metadata
- Supports arbitrary Pact read-only queries
- Results are JSON-encoded strings containing module information
