### `Contract`

| Property | Type | Description |

| `contractWasmHash` | `ContractHash` | Hash of the contract's WASM |
| `entryPoints` | `NamedEntryPoint[]` | Entry points defined by this contract |

import { RpcClient, HttpHandler } from 'casper-js-sdk';

const client = new RpcClient(new HttpHandler('http://node:7777/rpc'));

const result = await client.queryLatestGlobalState({
  key: 'hash-abc123...',
  path: [],
});

if (result.storedValue.contract) {
  const contract = result.storedValue.contract;
  console.log('Package:', contract.contractPackageHash);
  console.log('WASM hash:', contract.contractWasmHash);
  console.log('Protocol:', contract.protocolVersion);

  for (const ep of contract.entryPoints) {
    console.log('Entry point:', ep.name);
  }
}
```
