Token Interaction

The AI Agent SDK offers powerful token interaction capabilities on the Cronos blockchain. It supports retrieving token balances for both native tokens and ERC20 tokens, performing token transfers, as well as wrapping and swapping tokens.

This comprehensive feature set makes it easy for developers to build AI agents that smoothly interact with tokens.

To learn more about the underlying Developer Platform functionalities, please visit Developer Platform Client SDK Token Module.

2.1 Get native balance

Query the native token balance for the specified blockchain address using the Crypto.com developer platform.

Query

• Arguments

  address (str): The blockchain address to query.

• Example Query

  "Get native balance of <example-address>"

Response

• Returns

  str: A formatted string containing the native token balance for the address.

• Example Response

  The native balance for address <example-address> is <example-amount> CRO (CRO being the native token).
