# Constructing a Wax interface

The root Wax interface can be constructed using either default or custom configuration options. Custom options allow selecting a specific blockchain network (e.g. mainnet, testnet, or mirrornet), a specific Hive API endpoint (e.g. api.hive.blog) and also a custom REST API endpoint. It also provides settings to optimize for performance, network latency, or other custom needs.

# Default Wax initialization

Test it yourself: src/typescript/config/init-general/chain.ts

import { createHiveChain } from '@hiveio/wax';

// Initialize Hive Chain using default options
await createHiveChain();

Test it yourself on github codespace: src/python/default_wax_initialization.py

from wax import WaxChainOptions, WaxOptions, create_hive_chain, create_wax_foundation

wax = create_wax_foundation()

wax_custom_options = create_wax_foundation(
    options=WaxOptions(chain_id="f875a0b000000000000000000000000000000000000000000000000000000000")
)

# Initializing Wax interface with custom options

Test it yourself: src/typescript/config/init-general/chain-with-config.ts

import { createHiveChain, IWaxOptionsChain } from '@hiveio/wax';

// Define custom options
const customOptions: IWaxOptionsChain = {
  // Example custom chain ID:
  chainId: 'f875a0b000000000000000000000000000000000000000000000000000000000',
  // Example custom API endpoint:
  apiEndpoint: 'https://hive.custom.endpoint',
  // Example custom REST API endpoint:
  restApiEndpoint: 'https://rest.api.custom.endpoint',
  // Disable API timeout:
  apiTimeout: 0
};

// Initialize Hive Chain with custom options
const chain = await createHiveChain(customOptions);
