# 14.3 Bridging from FreCx to Polygon (Lock and Mint)

The process of moving tokens from FreCx to Polygon begins with locking tokens on the FreCx network.

The user initiates this process through the bridge interface by connecting their wallet and selecting the amount of FreCx to transfer. Once the transaction is confirmed, the specified amount of FreCx is locked in a bridge smart contract on the FreCx network.

After the lock transaction is verified, the bridge system triggers a corresponding mint operation on the Polygon network. This results in the creation of FreCx tokens(Polygon), which are credited to the user’s wallet on Polygon.

This process ensures that the original tokens remain secured while their equivalent representation becomes available on another chain.

## 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, and the optional `goal` query parameter:

```
GET https://docs.frequencychain.org/14.-cross-chain-interoperability-using-fswap/14.3-bridging-from-frecx-to-polygon-lock-and-mint.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
