You can use the `tx` data from the response to initiate a transaction on the source chain by calling the smart contract to complete the transaction. Please note that if you're dealing with an ERC20 Token, you need to approve the 'to' address beforehand.

**Additional technical note:** For ERC20 tokens, you must call the `approve()` function on the token contract to authorize the smart contract to spend your tokens before executing the main transaction. This is a standard security measure in the ERC20 token standard.

**Example flow:**

1. First approve: `token.approve(tx.to, amount)`
2. Then execute the main transaction with the provided tx data

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.wanchain.org/developers/xflows-api-old/1.4-examples.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
