# 📚 Holdstation/Worldchain-SDK

This document provides a comprehensive guide for integrating the **Holdstation/WorldChain SDK** to support core token functionalities within decentralized applications (dApps). The SDK enables seamless interaction with the WorldChain ecosystem, enhancing user experience and ensuring scalability for Web3-native applications.

The integration covers five key modules:

* **Token Integration:** Fetch and display a user's token list, including balances and token metadata (e.g., native tokens, ERC-20).
* **Transaction History Integration:** Retrieve and present detailed transaction history for any wallet on the WorldChain network.
* **Send Token Integration:** Enable users to send tokens with proper configuration and transaction handling via the SDK.
* **Swap Integration:** Facilitate token swaps directly within the app using WorldChain’s native swap functionality, allowing efficient asset conversion in a secure and user-friendly manner.
* **Widget Integration:** Embed prebuilt WorldChain widgets into the application (e.g., connect wallet, token selector, transaction modals), reducing development time and ensuring UI/UX consistency across Web3 components.

Each section includes implementation steps, SDK methods, and sample code snippets to support rapid and reliable development.
