# Configuration

> Configure network settings, RPC endpoints, and client options

## Network Configuration

The SDK provides pre-configured network settings for different environments. Understanding how to configure these properly is essential for connecting to the correct chain.

### Built-in Networks

The SDK includes two pre-configured networks:

<Tabs>
  <Tab title="Staging (Testnet)">
    Use staging for development and testing:

    ```typescript theme={null}
    import { Network } from "@oraichain/lfg-client-js";

    const network = Network.staging();

    // Network properties
    console.log(network.chainId);          // "lfg-staging-1"
    console.log(network.indexerConfig);    // Indexer endpoints
    console.log(network.validatorConfig);  // Validator endpoints
    ```

    <Tip>
      Staging network uses test tokens with no real value. Perfect for development.
    </Tip>
  </Tab>

  <Tab title="Mainnet (Production)">
    Use mainnet for production applications:

    ```typescript theme={null}
    import { Network } from "@oraichain/lfg-client-js";

    const network = Network.mainnet();

    // Network properties
    console.log(network.chainId);          // "lfg-mainnet-1"
    console.log(network.indexerConfig);    // Indexer endpoints
    console.log(network.validatorConfig);  // Validator endpoints
    ```

    <Warning>
      Mainnet uses real assets. Always test thoroughly on staging first.
    </Warning>
  </Tab>
</Tabs>

## Custom Network Configuration

For advanced use cases, you can create a custom network configuration with your own RPC endpoints.

### IndexerConfig

The Indexer provides read-only access to market data and account information:

```typescript theme={null}
import { IndexerConfig } from "@oraichain/lfg-client-js";

const indexerConfig = new IndexerConfig(
  "https://indexer.lfg.land/v4", // REST endpoint
  "wss://indexer.lfg.land/v4/ws" // WebSocket endpoint
);
```

### ValidatorConfig

The Validator handles transaction submission and blockchain queries:

```typescript theme={null}
import { ValidatorConfig } from "@oraichain/lfg-client-js";

const validatorConfig = new ValidatorConfig(
  "https://rpc.lfg.land", // RPC endpoint
  "lfg-mainnet-1", // Chain ID
  {
    CHAINTOKEN_DENOM: "uorai", // Native token denom
    USDC_DENOM: "ibc/...", // USDC denom
    USDC_GAS_DENOM: "uusdc", // Gas denom
    USDC_DECIMALS: 6, // USDC decimals
    CHAINTOKEN_DECIMALS: 6, // Chain token decimals
  },
  undefined, // Optional: custom denominations
  "My Trading Bot v1.0" // User agent
);
```
