createLaunchpadSDK(options?): LaunchpadSDK

Creates a fully configured LaunchpadSDK instance with smart defaults

• Auto-detecting wallet input format (private key, mnemonic, or Wallet instance)
• Providing smart environment-based defaults
• Handling wallet creation automatically

Parameters

Parameter	Type	Description
options?	{[key: string]: unknown; config?: Partial<LaunchpadSDKConfig>; env?: GalaChainEnv; wallet?: string | Wallet; }	Configuration options
options.config?	Partial<LaunchpadSDKConfig>	Additional SDK configuration options
options.env?	GalaChainEnv	Environment preset ('prod' or 'stage') for automatic URL configuration
options.wallet?	string | Wallet	Wallet input (private key string, mnemonic string, or Wallet instance)

Returns

LaunchpadSDK

Fully configured LaunchpadSDK instance

Example

import { createLaunchpadSDK } from '@gala-chain/launchpad-sdk';

// Generate new random wallet and create SDK with stage environment
const sdk = createLaunchpadSDK();

// From private key with environment
const sdkFromPk = createLaunchpadSDK({
  wallet: '0x1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef12',
  env: 'prod'
});

// From mnemonic with config
const sdkFromMnemonic = createLaunchpadSDK({
  wallet: 'word1 word2 word3 word4 word5 word6 word7 word8 word9 word10 word11 word12',
  env: 'stage',
  config: {
    debug: true,
    timeout: 60000
  }
});

// With URL overrides
const sdkWithOverrides = createLaunchpadSDK({
  wallet: process.env.PRIVATE_KEY,
  env: 'prod',
  config: {
    gatewayBaseUrl: 'https://custom-gateway.example.com'
  }
});

// Ready to use immediately
const balance = await sdk.user.getGalaBalance({ walletAddress: sdk.getAddress() });
