Configure general settings

Initialize and configure moniker​

Initialize the node with a human-readable name:


_1
jmesd init <your_custom_moniker> # ex., jmesd init michaelscott-node

☢️Moniker characters

Monikers can only contain ASCII characters. Using Unicode characters will render your node unreachable by other peers in the network.

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

Update minimum gas prices​

  1. Open ~/.jmes/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.

The recommended setting is: minimum-gas-prices = "0.15ujmes"

Example:


_4
# The minimum gas prices a validator is willing to accept for processing a
_4
# transaction. A transaction's fees must meet the minimum of any denomination
_4
# specified in this config (e.g. 0.25token1;0.0001token2).
_4
minimum-gas-prices = "0.01133ujmes"

[Optional] Public RPC Configuration​

If you would like your node's RPC to be publicly available and serve requests, follow the steps below. This is not compulsory.

  1. Open ~/.jmes/config/config.toml.

  2. Locate the RPC Server Configuration Options section ([rpc]).

  3. Change laddr = "tcp://127.0.0.1:26657" to laddr = "tcp://<YOUR_PUBLIC_IP_ADDRESS>:26657".


_2
# TCP or UNIX socket address for the RPC server to listen on
_2
laddr = "tcp://<YOUR_PUBLIC_IP_ADDRESS>:26657" # Example: laddr = "tcp://164.92.191.45:26657"

  1. Open ~/.jmes/config/client.toml.

  2. Change node = "tcp://localhost:26657" to node = "tcp://<YOUR_PUBLIC_IP_ADDRESS>:26657".


_2
# <host>:<port> to Tendermint RPC interface for this chain
_2
node = "tcp://<YOUR_PUBLIC_IP_ADDRESS>:26657" # Example: node = "tcp://164.92.191.45:26657"

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.

  1. Open ~/.jmes/config/config.toml.

  2. Locate the P2P Configuration Options section ([p2p]).

  3. Change external_address = ":26656" to external_address = "<YOUR_PUBLIC_IP_ADDRESS>:26656".


_6
# Address to advertise to peers for them to dial
_6
# If empty, will use the same port as the laddr,
_6
# and will introspect on the listener or use UPnP
_6
# to figure out the address. ip and port are required
_6
# example: 159.89.10.97:26656
_6
external_address = "<YOUR_PUBLIC_IP_ADDRESS>:26656"
