Configure General Settings

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

~/.xpla/config
│-- addrbook.json                       # a registry of peers to connect to
│-- app.toml                            # xplad configuration file
│-- client.toml                         # configurations for the cli wallet (ex xplacli)
│-- 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

Initialize and Configure Moniker #

Initialize the node with a human-readable name:

xplad init <your_custom_moniker> # ex., xplad init validator-joes-node

You can update your node’s moniker by editing the moniker field in ~/.xpla/config/config.toml

Update Minimum Gas Prices #

1. Open ~/.xpla/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.

Recommended setting is: minimum-gas-prices = "850000000000axpla"

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 = "850000000000axpla"

Start the Light Client Daemon (LCD) #

For information about the available XPLA Chain REST API endpoints, see the Swagger documentation. To enable the REST API and Swagger, and to start the LCD, complete the following steps:

1. Open ~/.xpla/config/app.toml.

2. Locate the API Configuration section ([api]).

3. Change enable = false to enable = true.

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

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

   swagger = true
   

5. Restart the service via systemctl restart xplad. 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.

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