# Configure general settings

The paloma testnet configuration is available [here](https://github.com/palomachain/testnet).

The following information describes the most important node configuration settings found in the `~/.paloma/config/` directory. It is recommended that you update these settings with your own information.

## Structure of ~/.paloma/config/

```bash
~/.paloma/config
│-- addrbook.json                       # a registry of peers to connect to
│-- app.toml                            # palomad configuration file
│-- client.toml                         # configurations for the cli wallet (ex Palomacli)
│-- config.toml                         # Tendermint configuration  file
│-- genesis.json                        # genesis transactions
│-- node_key.json                       # private key used for node authentication in the p2p protocol (its corresponding public key is the nodeid)
└-- priv_validator_key.json             # key used by the validator on the node to sign blocks
```

### Update minimum gas prices

1. Open `~/.paloma/config/app.toml`.

2. Modify `minimum-gas-prices` and set the minimum price of gas a validator will accept to validate a transaction and to prevent spam.

**Example**:

The minimum gas prices a validator is willing to accept for processing a transaction. A transaction's fees must meet the minimum of any denomination specified in this config (e.g. 0.25token1;0.0001token2).
`minimum-gas-prices = "0.01133ugrain"`.

## Start the light-client daemon (LCD)

For information about the available Paloma REST API endpoints, see the [Swagger documentation](https://lcd.paloma.dev/swagger/). To enable the REST API and Swagger, and to start the LCD, complete the following steps:

- Open `~/.paloma/config/app.toml`.

- Locate the `API Configuration` section (`[api]`).

- Change `enable = false` to `enable = true`.

```toml
# Enable defines if the API server should be enabled.
enable = true
```

Optional

Swagger defines if swagger documentation should automatically be registered. To enable Swagger, change `swagger = false` to `swagger = true`.

```toml
swagger = true
```

Restart the service via `systemctl restart palomad`. Once restarted, the LCD will be available (by default on port `127.0.0.1:1317`).

### Set up `external_address` in `config.toml`

In order to be added to the address book in seed nodes, you need to configure `external_address` in `config.toml`. This addition will prevent continuous reconnections. The default P2P_PORT is 26656.

```sh
sed -i -e 's/external_address = ""/external_address = "'$(curl httpbin.org/ip | jq -r .origin)':26656"/g' ~/.paloma/config/config.toml
```
