# Blockchain Functions

### Introduction

The AI Agent SDK integrates various functions from the Crypto.com On-Chain Developer Platform Client SDK as tools. These special tools serve as pre-built blockchain-related functions, which enable developers to interact with Cronos Chains in an easier way. <br>

The SDK offers a wide range of features, including:

* **Wallet Management**: \
  Create wallets, check balances, and use SSO wallet integration for a seamless user experience.
* **Token Interactions**: \
  Retrieve token balances (native & ERC20), perform transfers, wrapping, and swapping.
* **On-Chain Queries**: \
  Access transaction details, fetch blocks by tag or number, fetch smart contracts ABI, and resolve CronosID.
* **DeFi Features**: \
  Retrieve whitelisted tokens, explore available farms, and obtain detailed farm information from specified DeFi protocols.
* **Exchange Integration:**&#x20;

  Access real-time market data and trading pair information from the Crypto.com Exchange.
