Node configuration
The following information describes important node configuration settings within the ~/.dymension/config/
directory. It is recommended that you update these settings with your own information.
~/.dymension/config
│-- addrbook.json # Registry of peers to connect to
│-- app.toml # dymd configuration file
│-- client.toml # Configurations for the cli wallet
│-- config.toml # Tendermint configuration file
│-- genesis.json # Gensesis transactions
│-- node_key.json # Private key used for node authentication in the p2p protocol
└-- priv_validator_key.json # Key used by the validator to sign blocks
Initialize and configure moniker
We recommend saving the testnet chain-id into your Dymension client.toml. This will make it so you do not have to manually pass in the chain-id flag for every CLI command.
Initialize the node with a human-readable name:
dymd init <MONIKER> --chain-id=<CHAIN-ID>
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 ~/.dymension/config/config.toml
.
Set up external_address
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' ~/.dymension/config/config.toml
Set up seed_mode
In seed mode, your node constantly crawls the network and looks for peers. If another node requests addresses, it responds and disconnects. Seed mode will not work if the peer-exchange reactor is disabled. If you would like to run your full node in seed mode change the following config for your client.
seed_mode = true
Add seeds
To manually identify seed nodes, edit the following setting in config.toml
. For community provided seed nodes please visit the GitHub repository of the networks.
# Comma separated list of seed nodes to connect to
# Example:
seeds = "id100000000000000000000000000000000@1.2.3.4:26656"
Add persistent_peers
The nodes you specify are the trusted persistent peers that can help anchor your node in the p2p network. If the connection fails, they are dialed and automatically redialed for 24 hours. The automatic redial functionality uses exponential backoff and stops after 24 hours of trying to connect.
If the value of persistent_peers_max_dial_period
is more than zero, the pause between each call to each persistent peer will not exceed persistent_peers_max_dial_period
during exponential backoff, and the automatic redial process continues. The following is an example, for relevant peers see the networks GitHub repository.
# Comma separated list of nodes to keep persistent connections to.
# Example:
persistent_peers = "id200000000000000000000000000000000@2.3.4.5:26656"
