# Network configuration

To build AMT bridges on Bool Network, builders are required to send several transactions on the Bool chain. 

Just to remind you that at the early stage of the Bool chain, it is specialized as a distributed ledger to record vital information about committees, and cross-chain bridges. 

Hence, before carrying on, please follow the guides in this section to set up the Bool chain in your wallet. Without loss of generality, we take MetaMask as an example.

#### Configuration information

| Variable                      | Value                                     |
| ----------------------------- | ----------------------------------------- |
| Network name                  | Bool Testnet                              |
| RPC URL                       | <https://test-rpc-node-http.bool.network> |
| Chain ID                      | `47`                                      |
| Currency symbol               | `tBOL`                                    |
| Block explorer URL (optional) | <https://test.boolscan.com/>              |

{% hint style="info" %}
`tBOL` refers to the native token on the Bool Network testnet chain. One can request `tBOL` from the official [faucet](https://faucet.bool.network/).&#x20;
{% endhint %}

{% hint style="warning" %}
NOTE that `tBOL` has no trading value at the current stage. It serves testing purposes only.
{% endhint %}

#### Configure MetaMask for Bool testnet

1. Open MetaMask from the browser extensions.
2. Click on your network list on the top, and click `Add network`.
3. By clicking on `Add a network manually`, you should view the following page:

4. Finally, input the configuration information provided above to finish the set-up procedure.&#x20;
5. **Configurations!** The network configuration has been done, now you can request test tokens from the [faucet](https://faucet.bool.network/) and follow the subsequent instructions to construct your AMT bridges.

# 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:

```
